But on IC card fuel dispenser,�0�due to employ temperature control device. Turn on the device when necessary. Apart from the above functions IC card fuel dispenser should be provided with these traits such as explosion-proof electric safety, anti-dust, anti-interference, high applicability of power supply, high reliability, low ratio of failure, convenient for combination and expansion. Article IV Fuel dispenser and reader working flow Refueling process Under normal situation, filling process shou fuel dispenser ld be like this: When power supply is connected, the whole system begins to initia fuel dispenser te. As CPU get open command (nozzle has switched on) motor is startup; small flux solenoid valve switch on, oil flowing out of nozzle; CPU calculates volume filled according to pulse transmitted by sensor; at same time, large flux solenoid valve is open, being large filling state. Metering circuit counts paid volume and money on basis of pulse sign transmitted by flow sensor, then transmit these data and unit price into CPU that control the display of current filing. Metering CPU, if in randomly filing, will switch off solenoid valve and motor to end filing when receive stop sign (nozzle has switched off). If in presetting filing process, metering CPU will firstly close large flux solenoid valve when paid volume approaching to presetting volume (100ml~~300ml), small flux solenoid valve being open until paid volume is equivalent to presetting volume. Finally, current filing information such as filled volume, money and unit price (PPU) is transmitted into CPU and display on screen. The proportion of large flux to small flux is 10 to 1. The knowledge of fuel dispenser’s normal working procedure is of importance to judge trouble and failure. Reader flow chart of main programme Diagram 3-27: Filling operation flow fuel dispenser

it confessed that it was “uncertain about how much, if any, further tightening would be needed� Prices are rising and money is flowing freely in the euro area, making it more likely the European Central Bank (ECB) will raise interest rates at its next meeting on June 8th. Inflation edged up to 2.5% in the year to May, and the annual growth rate of the broad money supply averaged 8.4% in the three months to April, well above the 4.5% the ECB deems consistent with stable prices. In Germany unemployment fell to 11% in May, from 11.3% the month before. In France it dropped to 9.3% in April, compared with 9.5% the month before. Japan s core consumer prices, which exclude fresh food, rose by 0.5 fuel dispenser % in the year to April, a sixth straight month of inflation. Industrial production fuel dispenser grew by 3.8% over the same period. Canada s GDP grew at an annual pace of 3.8% in the first quarter. © 2006 .  About sponsorship Output, demand and jobs Jun 1st 2006 From The Economist print edition © 2006 .  About sponsorship Prices and wages Jun 1st 2006 From The Economist print edition © 2006 .  About sponsorship Germany Jun 1st 2006 From The Economist print edition After four disappointing years, the German economy looks poised to make a genuine recovery sustained by stronger domestic demand as well as buoyant exports. GDP is forecast to grow by 1.8% in 2006, according to the OECD s latest survey of the country. This will fall away to 1.6% in 2007 because of a scheduled increase in VAT. The country must press on with reforms to spur long-term growth, the OECD says, without jeopardising its short- term prospects. Deficit-cutting should now concentrate on spending restraint, rather than tax rises. Universities should be given the right to charge students for their tuition. More flexible employm fuel dispenser
