C/DC convert type switch power is universally adopted in fuel dispenser. Diagram 3-13: Structural sketch map of liner voltage stabilizing power Diagram 3-14: Structural sketch map of switch stable voltage power adopted DC/DC converter Diagram 3-15: Structural sketch map of switch voltage stabilizing power adopted pulse transformer As an electronic component in fuel dispenser, stable voltage power is easily failed and possibly leads to whole trouble of fuel dispenser once appear doesn’t work. Generally, liner voltage stabilizing power adopts 78 series special voltage stabilizing integrated circuit, such as 7805 and 7812, simple design and convenient maintenance. In Diagram 3-16, a popular liner voltage stabilizing power circuit of fuel dispenser is illustrated. Switch power supply adopted pulse transformer will not introduced here, reference with relevant boos when necessary. Diagram 3-16: Circuit diagram of liner voltage stabilizing power These integrated circuits of LM2576, LM4962 AND MC34063A are widely adopted in DC/DC transformer power supply. Intrinsic safety voltage stabilizing power supply in fuel dispenser This kind of direct current is able to employ in flammable and combustible environment only when mounted safety barrier. It also called intrinsic safety voltage stabilizing power supply illustrated in Diagram 3-18. Explosion-proof power supply is only used in explosion-proof box or an atmosphere without explosive gas, including its associated circuit. It is allowed to employ intrinsic safety power in explosive atmosphere, but must in explosion-proof box or an enviro fuel dispenser nment without explosive gas. However, its associated c fuel dispenser ircuit is permitted to use in explosive gas atmosphere if meet requirements concerned. The major difference between i fuel dispenser ntrinsic safety power and explosion-proof power is whether install safety barrier.

ak. Unlike Wall Street banks, research firms such as Gradient cater to institutional clients rather than retail customers and are independent of a broker-dealer. Therefore they are not subject to the rules of self-regulatory organisations, such as the New York Stock Exchange and NASDAQ, says Mr Coffee. Ms Hinton adds that it makes little business sense for independent research houses to publish “biased research�? Few institutional clients would be willing to pay fees of tens of thousands of dollars for shoddy work. And any reports by firms known to produce skewed research would be discounted by the market—and thus have no impact. Lynn Turner, a former chief accountant at the SEC, believes that hedge funds and research firms should be punished for intentionally publishing false, negative information “to the full extent of the law”—just as Wall Street analysts were punished for writing false, rosy stuff a few years ago. But Mr Turner cautions against any broader attempts to fight short-sellers. “Ethical short-sellers are good for the financial markets,�?says Mr Turner. After all, it was hedge-fund short-sellers who first unearthed financial jiggery-pokery at Enron and elsewhere, and who tipped off America s regulators. © 2006 .  About sponsorship An Icelandic financial saga Storm in a hot tub Mar 30th 2006 From The Economist print edition A Nordic nation s debt problems are unlikely to spread far beyond its shores MORE than almost anything, Icelanders like a soak in hot water. Reykjavik has more therma fuel dispenser l spas per head than any other city in the world. But fuel dispenser lately, the North Atlantic nation has been feeling more heat than it bargained for. On February 21st Fitch, a rat fuel dispenser ing agency, cut its outlook on Icelandic sovereign debt to negative from stable, drawing attention to a current-account deficit that ballooned to 15% of GDP in 2005 and fast-rising foreign debt. Since then, the krona has tumbled, the
