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. Articl fuel dispenser e IV Fuel dispenser and reader working flow Refueling process Under normal situation, fi fuel dispenser lling process should be like this: When power supply is connected, the whole system begins to initiate. 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

    e. Nobody in either party really knows who will bear the brunt of the blame. The bargaining about job cuts and plant-closings pits employers against the UAW, local politicians against Congress and states against each other. By the mid-term elections in November these skirmishes will coalesce into a more clear-cut battle between Democrats and Republicans, but it is not clear which issues will be to the fore health-care reform or state taxes? Trade or pensions? The politicking will be toughest in Michigan, a Democratic stronghold. Its unemployment rate is already above 6%, compared with 5 fuel dispenser % nationwide, and the city of Detroit recently had its debt downgraded again by the big rati fuel dispenser ngs agencies. Although Michigan has lost a quarter of its car jobs since 2001, the sector still accounts for 35% of the state s manufacturing employment, so more job cuts would hurt. This could damage Democrats in races they had expected to win easily. Debbie Stabenow, the state s junior senator, is a target for the Republicans. The state s governor, Jennifer Granholm, has been one of the Democratic Party s stars; but with her approval ratings down, her re-election in 2006 no longer looks assured. She went to Japan this summer in an effort to drum up investment. She also held a closed-door meeting in November with all 17 of Michigan s congressmen to plot strategy. A particular bugbear is a push by Congress to force firms with underfunded pension plans, such as the carmakers, to make up their shortfall in order to protect the government-backed Pension Benefits Guaranty Corporation. The industry is worried by a Senate bill that would force junk-rated borrowers, such as Ford and GM, to close their pension gap especially quickly. Ms Stabenow and Carl Levin, Michigan s other Democratic senator, were the only two people to vote against the bill, which now has to be reconciled with a less draconian House version. The unity the mid-west s politicians have displayed in Washington is missing in local politics. After a lot fuel dispenser
