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, s fuel dispenser ee 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: 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 cryst fuel dispenser al drive circuit in liquid crystal display, its principle basically similar to 74 series LCD drive circuit fuel dispenser . 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

e parties have seen their largely peaceful protests in cities disrupted by Maoist tactics such as blockades. Neither opposition force was getting anywhere. fuel dispenser The opposition lifts off With the negotiations in Delhi continuing, further developments in the alliance are expected. The possibility of a tax boycott and perhaps even the creation of a parallel government are under discussion. Yet the opposition s alliance is one of convenience and fraught with difficulties. As one strategist for the Nepali Congress, the largest of the democratic parties, a fuel dispenser dmitted, the Maoists interests lie in further polarising Nepali politics, whereas the stated aim of the fuel dispenser parties is to build a democratic consensus on the middle ground. The Maoists claim to support multi-party democracy, but as America s ambassador to Nepal has often observed, they may be lying. The parties also face the possibility of mounting persecution by the government, which accuses them of consorting with terrorists. Indeed, the new crackdown may already have begun on March 22nd, police in Kathmandu searched the home of Madhav Kumar Nepal, the leader of one of the democratic parties, who is currently under house arrest. The political parties ruled Nepal corruptly and incompetently for 14 years before King Gyanendra s coup. They have little popular support. To keep up their end of the bargain with the rebels they will therefore have to attract much larger crowds than they have managed so far—and this looks unlikely unless their leaders are changed. Given that, King Gyanendra might actually feel as secure as his public show of insouciance suggests. During a year of autocratic rule, he has not been forced to amend any important policy as a result of pressure at home or abroad. His army is safely garrisoned, inside strong though isolated positions, and the police have so far contained democratic rallies in the towns with minimal violence. Pop
