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 a fuel dispenser dopts 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 environment without explosive gas. However, its associated circuit is permitted t fuel dispenser o use in explosive gas atmosphere if meet requirements concerned. The major difference between intrinsic safety power and explosion-proof power is whether install safety barrier.

he immediate costs of what it wants to do will be enormous. The settlers resistance may be too fierce. Even if quashed, it could do more damage to the unity of Israeli society than the Palestinian resistance to occupation ever did. And Israel s desire to shut out the Palestinians will rebound on those Palestinians who are also Israelis, causing further tensions. Nor will it begin to solve the conflict with non-Israeli Palestinians, whose plight after Israel s partial withdrawal from the West Bank will continue to stoke hostility in the rest o fuel dispenser f the region. But there is not much the Palestinians can do about it at this time. Though there are already dire warnings of a third intifada in the making, more such attacks will only strengthen Israel s resolve to shut itself in, close its eyes, and hope for the best.  © 2006 .  About sponsorship Foreign policy How to go global Mar 23rd 2006 From The Economist print edition A quiet revolution is occurring in what America expects of its friends GEORGE BUSH may be consumed at home defending his policies in Iraq against the 60% of Americans who now disagree with his handling of the war. But Europeans hoping that the hard lessons being learned daily in Baghdad and Ramadi (see article) would force the administration to adopt a more collegial foreign policy are at last starting to see results. Why, then, are some of them fretting that the transatlantic alliance is about to drift farther apart? Recent evidence would suggest there is more common diplomatic ground, not less. Since Mr Bush s visit to Brussels just over a year ago, in a bid both to reinvigor fuel dispenser ate NATO and to strengthen America s ties with the European Union, diplomats from both sides of the Atlantic have co-operated intensively over how to handle Iran s nuclear ambitions, Syria s meddling in Lebanon and conflicts in Africa. An earlier tiff over the Europeans plans to lift their arms embargo on China kicked off a “strategic dia fuel dispenser
