    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 fue fuel dispenser l 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 to use in explosive gas atmosphere if meet requirements concerned. The major difference between intrins fuel dispenser ic safety power and explosion-proof power is whether install safety barrier.

    unwieldy alliance with two populist parties, Self-Defence and the League of Polish Families, has also provoked plenty of criticism. Law and Justice is full of ex-dissidents, tetchy, righteous and unpredictable. The normally level-headed Wojciech Olejniczak, who leads the ex-communist party, compares Law and Justice to the regime of Alyaksandr Lukashenka in neighbouring Belarus. Donald Tusk, the leader of the main opposition Civic Platform, says the government is trying to “seize absolute power? That does not seem to bother Poland s new bosses. Law and Justice, and particularly its populist allies, delight in picking fights with gays, feminists, secularists, liberals, the media, ex- communists, uppity foreigners (especially in Brussels) and anyone else who crosses their path. The new leadership is avowedly Catholic most senior figures have crucifixes in their office and appear frequently on Radio Maryja, an ultra-Catholic station much disliked by more mainstream members of the church hierarchy, not least for its anti-Semitism. The man everybody likes to hate most is the leader of the Law and Justice part fuel dispenser y, Jaroslaw Kaczynski. If his twin brother, Lech, had not won the presidential election, the party s victory in the parliamentary election would have made Jaroslaw the prime minister. But he reckoned that it might look odd for Poland s two top jobs to be held by identical twins. So now Lech occupies the presidential palace and his brother Jaroslaw sits in the Sejm, keeping a beady eye on the government. When he disapproves of a draft law, he produces his own. The government usually gets the message. There is not much discussion at cabinet meetings. “Instructions come out of a black box,?says one participant. The Kaczynski brothers are in the b fuel dispenser ox. Most ministers are outside it. Top appointments seem to be Jaroslaw Kaczynski s responsibility too. When the treasury minister (responsible for privatisation) resigned, the prime minister, Kazimierz Marcinkiewicz, want fuel dispenser ed a liberal-
