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 fuel dispenser : 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 thi fuel dispenser s 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.

congestion at existing ports may be hurting trade. Last summer, container ships were queuing to dock at Southampton, one of Britain s biggest ports—proof, says the union, that the market is not working properly. Fans of free markets are suspicious. “Congestion largely reflects the length of time it has taken to a fuel dispenser pprove planning applications,�says Ms Griffith, pointing out that several ports want to expand. The government s record on using industrial policy to assuage social ills (which underlay, for example, its attempts to preserve British shipbuilding) does not inspire confidence. And congestion problems can be solved by requiring firms to pay for road and rail upgrades, something that the review is also considering. It would be a shame if Britain s biggest experiment with a free-market transport policy were to come to an end so soon. © 2006 .  About sponsorship fuel dispenser Divorce laws Nuclear fission May 25th 2006 From The Economist print edition The law lords lay down guidelines for big-money divorce settlements IF A wife walks out on her wealthy husband after a short marriage, should the courts penalise her when dividing the spoils? If a rich husband leaves his long-suffering wife for a young bimbo, should the wife be awarded a bigger share of their joint wealth on divorce? No, said the House of Lords, Britain s highest court, this week in a firm rejection of the notion of blame being re-introduced into divorce proceedings. Straying spouses around the country breathed a sigh of relief. In 2000, the House of Lords ruled that assets should be divided according to a “yardstick of equality� and not simply on the basis of the claimant s—usually the wife s—financial need. Since then, judges have struggled to decide when they might depart from that broad principle of equal shares. The law lords have now tried to lay down some guidelines. Their first case concerned Alan Miller, a fund manager with an incom fuel dispenser
