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.
