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 fuel dispenser 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 fuel dispenser tackle with network voltage fluctuation, it is can’t afford because of complicated technology, expensive cost and difficult to maintenance.

s behind closed doors have achieved a great deal. Take so-called “golden parachutes�? the large pay-offs that even the worst exiting executives sometimes receive. In 1997 some 123 FTSE-100 top managers were entitled to severance packages worth more than a full year s pay. Quiet lobbying by institutions has cut that to just seven now. So wha fuel dispenser t then prompted established British investing institutions such as Standard Life Investments, Morley Fund Management and Hermes Pensions Management to mount an open rebellion against Vodafone s board? And does it signal the end of corporate diplomacy? The ol fuel dispenser d style of quiet engagement worked well when share ownership was more concentrated in the hands of a small number of British institutions. Fund managers could make a few phone calls, build a consensus and then “speak for Edinburgh”—or at any rate for a substantial block of shares. Dialogue was also made easier by the corporate broker, that curious British figure who is appointed to act as intermediate between a company and its investors. And unhappy institutions could always sell a firm s shares and move on. But times are changing. Institutional investors are a less cohesive group than they used to be. Almost a third of British shares are owned by foreigners now—up from 13% in 1989 (see chart)—many of whom have different rules of engagement. Much of Vodafone s stock is held by institutions in North America, where investors are used to flexing their muscles publicly. Institutions also find it harder to dump shares and run than they did. Many measure their results against those of index-tracking funds these days and thus want to hold at least a stake in the biggest firms. They are also under pressure from their clients to secure returns more similar to the double-digit profits made by buy-out firms and (some) hedge funds. So many once-s fuel dispenser taid insurers and pension-fund managers are adopting similar tactics, trying to wring out juicier deals by intervening actively in company manage
