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 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 fuel dispenser 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 fuel dispenser 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

ley, who won 78% of the vote almost four years ago, is hoping for another resounding victory on February 27th. If nobody wins a majority, there will be a run-off election in April. And if there are no surprises, Chicagoans will not have to worry yet about what might happen when the dynasty ends. © 2006 .  About sponsorship Mexican food Hold the avocado Dec 13th 2006 | WASHINGTON, DC From The Economist print edition Guacamole gets a gringo makeover LAST year Brenda Lifsey of Los Angeles bought a tub of “guacamole�?made by Kraft Foods. When she gave it a try, she noticed something amiss. “It just didn t taste avocadoey,�?s fuel dispenser he said. The label confirmed her suspicions. Guacamole is mostly mushed avocado. Kraft s version is less than 2% fruit. Instead, it uses modified food starch, oil, corn syrup and dye. On November 29th, Ms Lifsey sued Kraft for fraud. It was foolish of Ms Lifsey to expect real guacamole from Kraft. The company is famous for Singles�? plasticky squares of “cheese product”—and Miracle Whip, a sugar-laden substitute for mayonnaise. It does not seem too concerned about authenticity, and neither do consumers. The Centre for Science in the Public Interest raised this exact issue three years ago. “By passing off t fuel dispenser hese cheap pastes as guacamole, Kraft and others are practically begging to be sued,�?said Michael Jacobson, the centre s executive director. It has taken all this time for someone to act on his tip. According to Packaged Facts, a market-research firm, the Latin food industry will grow from $18 billion in 2005 to $25 billion by 2015. Already, Kraft is not the only company to be slapped for misunderstanding Mexican food. In November, the Qdoba Mexican Grill chain, featuring “signature burritos�? opened a store in a Massachusetts shopping centre. But a sandwich outlet called Panera was there first, and its lease allowed no other sandwich shops nearby fuel dispenser
