Household appliances retailer on Wednesday (February 24) on the Sony, Samsung Electronics, Toshiba, LG Electronics and a number of subsidiaries made a joint lawsuit, alleging they manipulated the U.S. electronics manufacturers to drive market prices.

The lawsuit also charged that the drive manufacturers to use Trade Organization, and discussion forums to some agreements, man-made control of CD, DVD and Blu-ray drive in the Sony PS3 and PC and other products to maintain a very high price.

The lawsuit said that when the drive began to decline when the price of that the defendants reached an agreement to prevent competitors from entering the illegal market and the prices are kept in the ultra-competitive level.

Prisco Electric to the District Court of Northern California, submitted a 31-page complaint. The suit alleges that these companies attempt to conspire to manipulate, improve, maintain and stabilize the price of drives sold in the U.S.. These companies control billions of dollars in CD-ROM market share of 90%. The defendant has a long history of engaging in anti-competitive products, such as DRAM memory, TFT-LCD display and CRT tubes and so on.

Prisco Electric did not specify the amount of compensation it requires. However, there have been reports that it asked for triple damages and asked the court to issue an injunction to prohibit these companies in the future price-fixing activities.

Samsung Electronics has received U.S. Department of Justice’s subpoena. Samsung Electronics indicated that it had manipulated the prices of things that drive is not available for comment. Is not linked to the Hitachi and Toshiba officials to comment on this news. According to “The Wall Street Journal” reported last fall, Hitachi and Toshiba have also received information on the investigation of price fixing drive the summons.

U.S. Department of Justice in October last year, began to drive the market to investigate anti-competitive products. Sony Optiarc America to the U.S. Department of Justice issued a subpoena. Sony’s The subsidiary said it would meet the Ministry of Justice and other agencies investigated. According to reports, this survey not only to Sony, but also other electronic manufacturers.

Button batteries in children’s toys, cameras and other appliances are increasingly common, its a threat to the safety of children, many people are not paying enough attention.

In the United States, 2006, 3613 button batteries have been eaten, most of them victims are children. In the past three or four months, California took place on three such cases since, including a child died.

California Children’s Hospital, Dr Richard points out that children like to do regarding all things hand into his mouth, while the shiny appearance of the battery button on their very attractive.

California doctor, Robert said, the battery would be swallowed after the child’s body can cause greater damage: stuck in the throat, esophagus, leaking a corrosive acidic substances, within a few hours into the throat or esophagus can be burned out of a hole; stuck in the lungs, blocking the airway, it will lead to suffocation. If you enter the stomach, would be relatively safer, because its acidic substances generally mixed with stomach acid, so that the 338794-001 , 361742-001 , 371785-001 battery can be passed smoothly digestive system.

Beijing Children’s Hospital, Dr. Wang Qiang, deputy director of surgery emphasized that swallowing the battery is most important is the timely detection. Since the battery is not immediately cause harm to the body, usually just as soon as the parents can be sent to the hospital. Of course, if conditional, parents can give their children self-induce vomiting.

Chemical batteries, is through the electrochemical reaction, the positive, the negative electrode active material of the chemical energy into electrical energy a class of devices. After long-term research, development, ushered in a wide variety of chemical batteries, widely used in the situation. As large as a building can only accommodate a lot, the great device, small enough to count the species in millimeters. All the time is not a better life for our service. The development of modern electronic technology, chemical batteries made very high demands. Each chemical battery technology breakthroughs have brought a revolutionary electronic device development. Modern society, people, daily life, the more and more inseparable from the chemistry of the battery. Now many electrochemical scientists focus their interest as a chemical battery powered electric car field.

Dry and liquid Inspiron 6400 battery,Inspiron 640m batteryThe distinction between dry and liquid cells is limited to the period of early cell development. The first battery from the glass container filled with electrolyte and two electrodes. Was launched in order to paste electrolyte-based batteries, also known as dry batteries.

There are still “liquid” batteries. Size is generally a very large variety. Such as those used as an uninterruptible power supply in large stationary lead-acid batteries or solar cells supporting the use of lead-acid batteries. For mobile devices, some using a full-sealed, maintenance-free lead-acid batteries, these batteries have been used successfully for many years in which the electrolyte sulfuric acid is fixed by the silica gel or glass fiber separator suction pay.

Disposable batteries and rechargeable batteries

Disposable batteries commonly known as “disposable” batteries, because their power runs out, you can not recharge using only discarded. Common disposable batteries, including alkaline manganese batteries, zinc-manganese batteries, lithium batteries, zinc batteries, zinc air batteries, zinc-mercury batteries, mercury batteries, battery and magnesium hydroxide, manganese batteries.

Rechargeable battery according to production materials and processes on different common are lead-acid batteries, nickel-cadmium batteries, nickel-iron batteries, nickel-metal hydride batteries, lithium-ion battery. The advantage is a long cycle life, which can be more than 200 full charge and discharge, and some rechargeable batteries power the load higher than most of the disposable batteries. Ordinary Ni-Cd, Ni-MH battery, the unique memory effect, causing inconvenience to use, often cause early failure.

Theory of battery charge time

The theory of the battery charge time: battery charger power divided by the output current.

For example: a battery 800MAH Inspiron E1405 battery,Inspiron E1505 battery for example, the charger output current 500MA then charging time is equivalent to 800MAH/500MA = 1.6 hours, when the charger shows charging is completed, preferably about half an hour or so should be given to the battery the complement of power-up time.

Fuel Cell

Fuel cell is a fuel’s chemical energy through electrochemical reaction into electrical energy directly to the device is the use of hydrogen fuel cell the anode is carried out by oxidation of hydrogen oxidation of hydrogen ions, while the oxygen reduction reaction carried out at the cathode, and coming from the anode generates hydrogen ions with the water. Oxidation-reduction reaction process can generate electricity. Fuel cell technology, including the existence, in alkaline fuel cell (AFC), phosphoric acid fuel cell (PAFC), proton exchange membrane fuel cell (PEMFC), molten carbonate fuel cell (MCFC), solid oxide fuel cell (SOFC), as well as the direct methanol fuel cell (DMFC), etc., of which the use of methanol oxidation as a positive response to fuel cell technology, but is optimistic about the industry and positive developments.

1. Did not read the engine electronic control unit (ECU) records the fault code can not be dismantled before the battery cable

Because the fault code read before they hastily removed the battery cable or unplug the power supply fuse, due to interruption of power supply ECU, stored in its random access memory in the fault code will be automatically eliminate. If you want to re-access the fault information is necessary to repeat or reproduce the failure occurred when the working condition and environmental conditions, but who can not start the engine, so that the future operation would no longer be able to obtain fault code, lost an important failure to judge information, so Prior to the repair electric Inspiron 1100 battery,Inspiron 1150 battery motors, should be required to record the first ECU fault code, and then carry out other repairs.

2. Ignition switch is connected (ON) position, can not be easily removed battery cable

When the ignition switch is (ON) position, regardless of whether the engine running, you can not remove the batteries or unplug the power cord fuse. Because of sudden power cuts may produce self-inductance of the coil circuit electromotive force, which appears very high transient voltage (and sometimes even as high as ten thousand volts), so that ECU and related sensors, microelectronic devices were seriously damaged.

In addition, with the battery voltage is the same as any other electrical devices, wires, ignition switch in the ON position when they can not be removed, otherwise the same will produce self-inductance of the coil related to EMF, thus ECU or sensor. These electrical installations include: ignition system, idle speed stepper motor, ECU’s programmable read-only memory (PROM), fuel injector, air-conditioning, and other electromagnetic clutch, as well as some of the ECU connection lines.

3. Can not just remove Inspiron 1501 battery cable to use the method Clear fault code

For most electric motors run, remove the battery cable or remove the fuse leading to the ECU to maintain power for 30 seconds, you can clear the fault code stored in the ECU. But for some engines it is not suited to this approach, because the vehicle anti-theft, audio, quartz, etc. memory (including anti-theft password) are also stored in random access memory in the memory after the power failure will also be removed together, resulting in phenomena such as sound lock code on these engines should be based on the requirements of the maintenance manual methods to clear the fault code, and must not arbitrarily remove battery cable.

IBM’s 18 federal agencies announced that it would provide a period of 8 years worth 74.4 million U.S. dollars of computer equipment and modernization of office equipment.

Clustered storage an increasingly popular, not only users of its increasing concern, the major storage vendors are stepping up their action. Recently Dell has agreed to buy the professional vendor Exanet clustered storage assets issued an offer.

During the economic downturn of last year, clustered storage vendor to obtain unexpected success, as represented by Isilon clustered storage vendor to obtain a contrarian’s income, which also made large IT vendors are eyeing a new piece of cake. Last year, HP acquired Ibrix, LSI acquired Onstor, Dell is also unwilling to people, I want to join through the acquisition of Exanet clustered storage market.

Starting from the acquisition of EqualLogic, Dell in the past two years in the data storage market has become a major manufacturer. Now Dell wants through the acquisition of Israeli companies Exanet set his sights on cluster file system and NAS market. Exanet last month filed for bankruptcy protection.

A Dell spokesman, said Dell “has been the acquisition by the Israeli court approval after the liquidation of Exanet assets - primarily patents and other IP - sent out an offer. We are very pleased to have this opportunity to purchase Exanet, which not only storage technology to our advantage, but it also let Dell have the opportunity to develop the Israeli market. memory is Dell’s enterprise-class solutions in an important component of, Exanet’s resources are an extension of Dell’s storage. Israeli court has not yet formally approved this transaction, we will not be completed or agenda guess. ”

The right Exanet of NAX-based Linux platform for the acquisition should be considered as clustered NAS market, the main data storage vendor’s recent moves.

As we all know the battery will cause great harm to the environment, but as one of the necessities of life, people are unable to leave it, so how to find an alternative product will become the scientists have always hoped to overcome many problems. According to British media reported yesterday, giving us several generations to provide kinetic energy of the battery, will soon be thrown into the dustbin of history.

British scientists say they invented a plastic that can store and release energy, which will allow us to use the telephone, electric car, even in the dressing, it’s always brought a revolutionary change. For example, mobile phones and Walkman player can be used like a credit card-sized card to provide a small mechanical power.

This technology helps manufacturers such as paper folding, and carry the same computer screen. And it can be used to create “power clothes” in the people moving charge, when the slow release of energy in keeping warm during cold weather.

This stored electrical plastic works similar to traditional batteries, from 3-layer fiber material composition. Covered by two layers of carbon fiber upper and lower conductive resin, respectively, as positive and negative; the middle of laminated glass fiber. British Airways Department of Imperial College, said Dr. Emile Greenhalgh, exactly speaking, is not a new invention but a super capacitor batteries. His team invented a prototype plastic, about five square inches in size and very thin, charging five minutes can be used for LED screen 20 minutes of power.

Dr. Greenhalgh is working with Volvo Car Corporation, launched a three-year cooperation plan at a cost of 3 million pounds development of hybrid cars, he said: “Thanks to our newly invented materials, we believe that the future of the automobile can be the roof or the doors to be dynamic. ”

The use of this material than these, for example, that people can have like a credit card-sized mobile phone, because they no longer need bulky batteries, or a laptop computer can also get energy from the shell, but also can be used longer.

He also added that the new material charge and discharge faster than conventional batteries, but does not occur when using a chemical reaction, therefore live longer.

Scientists planned to use this material to replace the Volvo car trunk inside the metal chassis. This Volvo Car batteries can reduce the size of its hybrid, you can reduce the weight and more efficient.

Dr. Greenhalgh said: “No one can create with this new type of plastic match the material, within ten years it will replace the old batteries.”

Was once labeled a “sunset industry” label lead-acid battery industry, is being renewed vitality.

Despite the continued impact of the battery by other materials, and suffer from frequent fluctuations in lead prices, lead-acid battery business of the living space was once compressed, but its inherent technology, price, resource advantages, as well as the rapid development of new energy industries, people have reason to remain confident in its prospects.

Have a bucketful of trouble

Other materials, batteries, especially lithium-ion batteries, since access to the battery industry, “will be at an alarming rate, all the time we do not covet the status of lead-acid battery industry.” Zhejiang days to the battery (Jiangsu) Co., Ltd. Deputy General Manager of any fu warned.

Repeatedly over the past decade by the battery will be replaced by other materials, such as the impact of arguments, walking in the prejudices of the lead-acid battery industry, once bleak.

China is the world’s largest producer of lead-acid batteries, consumer and exporter. In 2008 the spread of the global financial crisis, to the abolition of export tax rebate lead-acid battery industry has brought no small impact on corporate profits decline, and many small businesses were forced to stop production or close down.

In addition, the enterprises are small and scattered, low-level redundant construction and overcapacity, disorderly competition in the industry, the status quo, as a result of discrete procurement price fluctuations in the lead repeatedly Ai Zai, have made lead-acid battery industry “bruised and battered.”

But, this does not affect the industry in the development of the industry held by the optimism.

Can not hide the inherent advantages of

Referred to the future development of the industry, he served as Anfu repeatedly emphasized words, “full of confidence.” At the recent Summit Forum of China lead-acid battery industry, he has a stage, we appeal to everybody as a lead-acid battery industry, the development of “Drum applause.”

Anfu very good reasons office.

Lead-acid battery technology is mature and reliable, in many important applications have been successfully used for more than a century, the product durable, well received by various types of user trust, which is driving a fundamental factor in market growth.

“Lead-acid battery is the most price-competitive with battery.” Ren fu said, the price significantly lower than the lithium batteries, nickel-hydrogen batteries, fuel cells and other new battery, “the size of lead-acid battery production makes their prices in a relatively a low level. ”

In addition, its raw material can be recycled. Ren fu said, “lead-acid battery contains 60% to 80% of the recycling of plastic and lead recycling of these materials for both the user and the environment benefit.”

“Although many environmentalists have their bias, but it can be seen everywhere throughout the country have been discarded batteries, really can not find a discarded lead-acid batteries.” Chemistry and Environment South China Normal University, says Dean CHEN Hong-yu .

Lead-acid battery pollution is mainly concentrated in the lead smelting and manufacturing stages of plate current with the technology and equipment upgrading, lead-acid battery industry has undergone tremendous change, with advanced production technology, special equipment, fully capable of with international practice. The industry has long been the mainstream of business has changed in the past high-pollution production status, product technology has been achieved, “low energy consumption,” and manufacturing equipment “energy saving” and embarked on a clean production path.

“Through strong environmental protection facilities and measures for the implementation of the certified industry-standard rate of corporate environmental emissions by 5 percent a decade ago, increased to 99.5%, lead-acid battery as a class of high resource recycling of energy products, are not consume resources the industry. “China Lead-Acid Battery Industry Association, said the Secretary-General in Iraq Xiaobo.

“Especially in today’s emphasis on resource recycling, lead-acid batteries can be described as an unparalleled resource advantage.” Battery, Shenyang Institute of Fan Guang-Yu said that its resources the characteristics and cost-effective advantages, it laid the foundation for a long time.

New market for old signs

In the current race to the era of the development of hybrid electric vehicles, with reliable and the characteristics of raw materials can be recycled, lead-acid batteries may be preferred.

In fact, the lead-acid batteries in electric vehicles, the advantages of industrial development has been concerned about. Public letter to the Department of State has issued a “new energy automobile manufacturing companies and product access management rules,” new energy vehicles will be divided into initial stage where the development period, three stages of maturity. Among them, the use of lead-acid batteries and nickel-metal hydride batteries in hybrids are classified as mature, be the first into the industrial development.

“This grant from the national policy lead-acid batteries as a new energy direction for the positioning of automotive development.” China Electrical Equipment Industry Association vice president of lead-acid storage battery branch, said Zhou Rui.

At the same time, with the energy, the environment is becoming increasingly prominent, solar, wind and other renewable energy sources will enter a new period of development. And renewable energy use, need a lot of energy storage cell to regulate its continuity and stability.

ZHOU Rui-Long said, according to the world’s leading organizations predicted, the 2010 to 2020, the global photovoltaic industry will reach 34% annual growth rate, but thanks to the emerging needs of the rural off-grid PV off-grid system would be far greater than the growth rate grid system, “Therefore, for the photovoltaic industry, the battery market is enormous.”

In this regard, Fan Guang-Yu also said that “industry generally agreed that the next two years, off-grid lighting systems, the demand for lead-acid batteries, electric bicycle battery demand than the more rapidly, while the market capacity will be much larger.”

For example, he said, precisely because of battery and energy sources, Shenzhen Investor battery company with new energy as the starting point a few days ago, successfully landed on the Main Board of the U.S. NASDAQ.

Communications industry to promote the rapid development of data centers and other key areas of standby battery life. In some areas, such as “BRIC”, carried out a large-scale telecommunications expansion, and further extends the battery industry development. In addition, there is a broad-based global transportation market, electric, railway battery market.

Manufacturing technology continues to mature, price competitiveness, the only renewable raw materials, office fu has made a number of advantages makes the following judgments, “the next decade, lead-acid batteries is difficult to be replaced and will be dominant.”

New needs emerging, with other types of batteries together to compete, only the market is unique, and it is the best referee. “Now a series of new energy needs are likely to re-form a new territory under the battery, I believe that this piece of old lead-acid batteries will sign the more light the more rub.” Zhou Rui confidence.
