But on IC card fuel dispenser,�0�due to employ temperature control device. Turn on the device fuel dispenser 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 Ref fuel dispenser ueling 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

ing India s nuclear weapons ambitions ought not to be in Mr Bush s gift. When Congress is asked to change America s anti-proliferation laws, it should say no. © 2006 .  About sponsorship Shareholder democracy Ownership matt fuel dispenser ers Mar 9th 2006 From The Economist print edition But there are limits to shareholder power THERE is a whiff of revolution in the air. America s shareholders are growing restless, and the bosses of the companies they own seem increasingly nervous as they peer out from behind their boardroom curtains. On one side are veteran corporate raiders, s fuel dispenser uch as Carl Icahn and Kirk Kerkorian, and the growing army of imitators they have inspired in the hedge-fund industry. On the other, pension- fund activists are threatening one of the fiercest proxy seasons ever, spraying companies with resolutions demanding curbs on executive pay and majority voting in board elections. Surely there is nothing wrong with the sight of American shareholder democracy in action? Not so fast, say the country s beleaguered managers. The balance between owners and managers that has underpinned America s version of capitalism and made it the best in the world at creating wealth is a delicate one. The system s original genius was to tie the raising of capital to the transfer of ownership rights using sales of equity on public securities markets. Shares gave their buyers more than just a slice of the financial action in the form of dividends. They also carried with them the potential for control of the firm, as countless battles have testified. This mechanism facilitated the rise of corporate capitalism and the astonishing material wealth it has provided in the world s rich countries. You might think that you would fiddle with it at your peril. Those bullying, hectoring shareholders are thus, say some, a dangerous bunch who risk diverting managers from sensible stewardship towards short-term recklessness. That charge is difficult fuel dispenser
