ariable DC voltage. Diagram fuel dispenser 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 D fuel dispenser iagram 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: 74HC95. The drive circuit of liquid crystal display is composed of double D trigger 74HC74 and double input exclusive-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.

PA THE timing fuel dispenser could not have been more provocative. Just two days before the British and Irish prime ministers were due to announce a plan to revive self-government in Northern Ireland, Denis Donaldson, a former top I fuel dispenser RA man turned British agent, was found shot dead in his wretched last refuge in north-western Ireland. Although the IRA denied responsibility, the murder recalled the worst of the violence that the group had supposedly abandoned since laying down their arms last year. It is not the first time that Mr Donaldson s fortunes have been intertwined with those of devolved government. The head of Sinn Fein s Stormont administration after power-sharing between unionists and republicans began in 1999, he was a familiar figure around the Assembly. Persuasive, on-message, a friend of Gerry Adams, the party s leader, and of Martin McGuinness, its chief Brothers in arms negotiator, he seemed to embody the new, moderate republicanism. But it was the discovery of an IRA spy-ring at Stormont supposedly controlled by Mr Donaldson that brought devolution screeching to a halt in October 2002. When he vouchsafed, in December 2005, that the spy-ring was a hoax and he had in fact been working for Britain s security services since the 1980s, people marvelled that he walked away alive. Proof, it was said, of the IRA s new commitment to peace and politics; Freddie Scappaticci, another IRA turncoat, had also been permitted to vanish discreetly. Mr Donaldson, alas, disappeared only to be hunted down later and murdered. Mr Adams argues that Mr Donaldson s killers clearly wanted to derail the peace process. That may be correct. Many observers blame dissident republicans, who have often tried to disrupt Sinn Fein s progression towards peaceful political engagement. Some, of course, cry British dirty tricks and blame the ‘securocrats�who do not like the way the war has ended. But unionists insist that the IR fuel dispenser A
