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 applicabi fuel dispenser lity of power supply, high reliability, low ratio of failure, convenient for co fuel dispenser mbination and expansion. Article IV Fuel dispenser and reader working flow Refueling process Under normal situation, filling 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

be passed on, and a large chunk of that seems destined for philanthropic purposes—not least because involving children and grandchildren in the running of a foundation is increasingly seen as a way to give them a sense of purpose and to pass on family values. Self-interest A secondary motive may be the desire to take advantage of the many tax incentives and other fixes that can make a wealthy person look virtuous at an appealingly low cost. America has the most gener fuel dispenser ous treatment of charitable giving, allowing taxpayers to deduct their donatio fuel dispenser ns from their taxable income. In Britain, too, the tax system has become much more philanthropy-friendly. Other parts of Europe are following slowly. The European Foundation Centre is lobbying for better tax treatment throughout the European Union. A particular concern is the harsh tax regime that some countries apply to giving abroad. The recent tax reforms in Britain have not changed the tendency to give out of income rather than assets, in sharp contrast to the Americans, says Les Hems of the Institute for Philanthropy in London. There is currently no British version of America s popular “charitable remainder trust”—a device that allows a donor, say, to give away his house, claim an immediate tax break and then continue to live in it until his death, when the remaining value of the asset goes to the designated charity. One of the strongest trends in American philanthropy in recent years has been the rapid growth of donor-advised funds, offered by money management companies such as Fidelity, whose fund is now America s fifth-biggest charity. These funds allow individuals to commit themselves to a donation and claim their tax deduction, but defer nominating a beneficiary and actually paying out the money until a later date. This has led Congress to suspect foul play—though not by Fidelity, which has a decent average pay-out rate of 25% of donated money each year.
