ariable DC voltage. Diagram 3-9 is a drive circuit. The display mode of volume and sales on main display boa fuel dispenser rd 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 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 fuel dispenser 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 net fuel dispenser work voltage fluctuation, it is can’t afford because of complicated technology, expensive cost and difficult to maintenance.

a chance to reverse his city s decline, but only if Turkey unconditionally reopens its borders. By doing thi fuel dispenser s, Turkey would regain some moral high ground, as well as securing access to strategic markets in Central Asia and beyond. Kars could even become a regional hub in the Caucasus, especially if a rail link to Armenia s capital, Yerevan, were restored. Trade volumes between the two countries, now averaging a measly $100m a year, almost all of it conducted via Georgia, should soar. There is more. As many as 200,000 members of the Armenian diaspora return to their homeland every year. Many would like to cross the border into Turkey in order to visit Armenian archaeological sites. The tourist trade could be worth millions of dollars. “They would also meet Turks and realise they aren t quite as evil as they imagined,�adds Kaan Soyak, co-chairman of the Turkish-Armenian Business Development Council. But how to break the diplomatic deadlock? Mr Alibeyoglu s answer is to take matters into his own hands. In 2000 he drove to the Armenian town of Gyumri, where he appeared on television with his fellow mayor and appealed for peace. This autumn, Mr Alibeyoglu will host a festival that features, for a second time, performers from Armenia, Georgia and Azerbaijan. The Armenians will have to make a tortuous journey via the Turkish cities of Trabzon and Istanbul. But the mayor hopes that, one day soon, their journey will be much quicker.  © 2006 .  About sponsorship Ani, a disputed city Haunted by history Jun 15th 2006 | ANI From The Economist print edition The ruins of a contested capital are s fuel dispenser till hostage to geopolitics WHATEVER you think about ghosts, it is hard to speak of this desolate plateau on Turkey s eastern edge without using the word “haunted� A millennium ago, Ani rivalled By fuel dispenser zantium as one of the great cities of the Christian world.
