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 tube Diagram fuel dispenser 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. In recent years, D fuel dispenser fuel dispenser

en in shorter supply than snow in the Amazon. Lula had been expected to win outright in the general election on October 1st. Instead, Geraldo Alckmin, until recently the governor of São Paulo, the biggest state, did unexpectedly well, winning 41.6% to Lula s 48.6% and forcing the run-off. Mr Alckmin was helped by a last-minute scandal of the kind that the fuel dispenser Workers Party has produced like popcorn in the past four years. This one involved party workers offering to pay 1.7m reais ($800m) for a dossier which smeared José Serra, Mr Alckmin s successor in São Paulo. But he also benefited from anger against the government in the south and centre-west, where drought and the strong real have hurt farming and some industries. In a month of campaigning since then, Lula has widened his lead to 20 percentage points, if the polls are right. To repair relations with farmers, he recruited Blairo Maggi, newly re-elected as governor of the grain-growing state of Mato Grosso and himself the world s largest soyabean producer. He is courting the disgruntled middle class, which does not benefit from federal cash transfers to the poor—nor from those that go to the rich through high interest rates on government bonds. In debates, Lula has managed to make the PT s serial scandals sound almost like a virtue. “The time when things are swept under the carpet is over,�he declared. Most of all, he found a way to turn the pro-business leanings of Mr Alckmin and his Party of Brazilian Social Democracy (PSDB) against them. Lula s predecessor as president, Fernando Henrique Cardoso, privatised electricity distribution, the telecoms monopoly and Companhia Vale do Rio Doce, a mining giant. Mr Alckmin has overseen São Paulo s own privatisation programme. Such is the PSDB s addiction to sell-offs, Lula suggested, that it would sell parked cars off the street. Brazilians tend to forget the successful sell-off of telecoms, banks and many industries. They remember that electricity privatisation was rushed and inco fuel dispenser fuel dispenser
