ow pulse from sensor and calculating data. The measuring CPU exchanges and controls data or information th fuel dispenser rough the process circuit of communication signal and center-control computer. EEPROM: generally, fuel dispenser adopts model 24C16 of EEPROM, which is used for memorizing calculated information, unit price, oil density, etc. The IC chip matched with measuring CPU mainly has the memory chip of calculating data, like HX1215 and 24C16. 2.2 Keyboard At present, there are two types of keyboard used on fuel dispenser, parallel scan keyboard and serial scan keyboard. Different manufacturers employ various model keyboards with these logical units that illustrated in Diagram 3-2, 3-3 and 3-4 in their fuel dispensers. Diagram 3-2: Keyboard sketch map of fuel dispenser Diagram 3-3: Structural sketch map of parallel keyboard Diagram 3-4: Structure sketch map of serial keyboard Liquid crystal displays are adopted in keyboard screen and main display screen on which showing unit price, volume and sales. The components installe fuel dispenser d on keyboard varied largely, some manufacturers adopting touch switch, others membrane key or rubber keyboard. Parallel keyboard, high speed with many lines, is restricted by data signal length due to interference. However, serial keyboard with high anti-jamming and few lines is much freer from the length of data line. Both serial keyboard and parallel keyboard are feasible plans. 2.3 Main display screen Liquid crystal display (LCD) is generally adopted as main display board of fuel dispenser recently because it is clean and beautiful in sunlight. In order to be visible at night, transparent or semi-transparent liquid crystal screen is adopted against matrix backlight board with light-emitting diode, which also have hearting function. Display usually adopts 6-6-4 type illustrated in Diagram 3-5, showing 6 digits on volume and money, 4 digits on unit price, each item data has two digits after decimal point.

a tonne barrier amid concern of strikes at mines in Chile and Mexico. BP announced that net income for fuel dispenser the first quarter had fallen by 15% in a year, to $5.6 billion. The company s profit was partly affected by last year s shutdown of its oil refinery at Texas City following an explosion that killed 15 people. This week federal regulators fined BP s North American operations $2.4m for safety violations at a refinery in Ohio that were “similar to those found during an investigation�of the fatal blast. Slippery slopes The price of oil eased a little after touching $75 a barrel in trading late last week. Meanwhile, George Bush said he was suspending deposits to America s Strategic Petroleum Reserve until the autumn in an effort to boost oil supplies. The move (which will have a small effect on overall oil supply) comes amid growing political pressure in the United States over high petrol prices.

The bank knocks the spots off its competitors, whether in pure “investment banking� the traditional craft of underwriting and mergers and acquisitions in which it made its name, or in its new focus, trading for customers and its own account. Even compared with leaders in other industries, Goldman makes spectacular returns. Among its latest record-busting yardsticks was a 40% quarterly return on equity. The average pay-packet of its 24,000 staff last year was $520,000—and that includes a lot of assistants and secretaries. This makes the bank an easy target for populist politicians and tabloid newspapers. The real reason why Goldman should matter to outsiders is not because it is a manufacturer of mi fuel dispenser
