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 fuel dispenser 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 d fuel dispenser isplay 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 exp fuel dispenser losion-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

, falling. Yet the British have less confidence in their government s ability to crack down on violence and crime than the French, Germans, Italians, Spanish or Americans, an Ipsos-MORI poll revealed last week. For that, thank a run of bad news which has Britons reeling from headline to headline. If one were to believe the tabloids, paedop fuel dispenser hiles are rampaging through the schools and undeported foreign felons through the countryside. A string of crimes by convicts on early release culminated in a particularly sad and nasty sexual assault on a three-year-old girl, which came before the courts this month. Carefully stoked by the press, popular passions are running high against everyone involved with the administration of justice. One home secretary (the minister in charge of prisons, the police and immigration) got the boot in May. His successor, John Reid, is busily putting the boot into everyone else, lambasting judges for being fuel dispenser soft on crime and scaring the daylights out of his department. The Tories are demanding more prisons. Meanwhile, Tony Blair was due on June 23rd to urge a new balance between the rights of offenders and those of victims in favour of the latter. Right question, wrong answer Mr Blair is right to ask whether society s interests are best served by the status quo. The criminal justice system requires a degree of public trust that at the moment is lacking. This is a chance not fo fuel dispenser r lock-‘em- up posturing, but for a dispassionate look at how to make the administration of justice more effective. Start with one simple fact behind most of the headlines Britain s prisons are bursting at the seams. At current rates of sentencing, the inspector of prisons warns, jails will be full by September. This matters the shunting of prisoners from pillar to post by harried staff is undermining efforts to return offenders to society in a state fit to stay there (see article). They lose touch with their families; they leave courses and drug-detox programmes; wardens they knew l
