    ariable DC voltage. Diagram 3-9 is a drive circuit. The display mode of volume and sales on main display board adopt 6 digits liquid crystal display (Model ED-139, see Diagram 3-11), PPU or unit price r digits LCD (Model ED-830, see Diagram 3-12). Diagram 3-9: Static circuit and wave of LCD tube Diagram 3-10: Drive circuit of one-digit tube Diagram 3-11: ED-139 6-digit LCD Diagram 3-12: ED-830 4-digit LCD Display drive chip often adopts 8-digit memory/flip-latch: fuel dispenser 74HC95. The drive circuit of liquid crystal display is composed of double D trigger 74HC74 and double input excl fuel dispenser usive-OR gate 74HC86. Some fuel dispensers adopt special crystal drive circuit in liquid crystal display, its principle basically similar to 74 series LCD drive circuit. A few fuel dispenser manufacturers adopt light-emitting diode (LED) as display components of display board because its cost is low and need not backlight in evening. The defect of this display component is bad display effect, especially under extensive sunlight, and much electricity consumption. LED display drive circuit also has parallel and serial drive, similar to LCD display drive circuit in terms of structure. Very few fuel dispensers adopt matrix or color liquid crystal display, showing much information. However, it largely increases cost. 2.4 Power supply Stable voltage power supply used in explosion-proof fuel dispenser Most of fuel dispensers adopt explosion-proof type, installing liner stable voltage power supply or switch voltage power supply. Switch voltage stabilizing power supply includes power transformer, DC/DC converter, 220V direct commute and pulse transformer, illustrated in Diagram 3-14 and 3-15. Due to cost-efficient and simple design, liner stable voltage power is widely adopted. However, it is affected by exterior network voltage. Although pulse transformer is able to tackle with network voltage fluctuation, it is can’t afford because of complicated technology, expensive cost and difficult to maintenance. In recent years, D fuel dispenser

    ying their taxes in full. But another risk is that, if it does work, it could induce the government to keep relying on higher tax revenues not spending cuts to sort out its public finances. If that happens, it could hold back growth. The warning signs are all there in the draft 2007 budget. Mr Berlusconi claims to have found 67 new taxes hidden in the small print. In his evidence to parliament on October 12th, the governor of the Bank of Italy, Mario Draghi, said gloomily fuel dispenser that the budget left the trend of current spending “substantially unchanged� an implicit criticism.

About sponsorship French icons Liberation, Equity, Sobriety Oct 19th 2006 | PARIS From The Economist print edition Attacking the things that make France French ONE by one, icons of the French way of life are under attack. The government is to ban smoking in public places, threatening an end to the smoke-filled café beloved of students. Speed cameras on motorways are bringing to a halt the annual August carnage as families rush to the beach. Now it looks as if Libération, a newspaper founded by Jean-Paul Sartre that is the bible of the left-bank intelligentsia, could be heading into history. What is happening to France? The first two reflect health-and-safety worries. The decision to ban smoking in public places from February 2007, and from cafés and restaurants a year later, is meant to curb France s high lung-cancer rate; the government blames smoking, directly or indirectly, for 65,000 deaths a year. It is a similar tale for speed cameras. In 2001 the French were traffic-accident champions, killing over 8,000 people on the roads. Between 2003, when the first cameras were installed, and 2005, the annual number of deaths fell to just above 5,000. The ill health at Libération is financial. The pape fuel dispenser
