ow pulse from sensor and calculating data. The measuring CPU exchanges and controls data or information through 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 fuel dispenser matched with measuring CPU mainly has the memory chip of calculating data, like HX1215 and 24C16. 2.2 Keyboard At fuel dispenser 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 installed 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.

ists fear that the LHC will be the last big accelerator built. Their subject, intellectually important though it undoubtedly is, has little practical application. It may therefore become too expensive for taxpayers to sustain. However, a paper just published in Nature Physics by Wim Leemans of the Lawrence Berkeley National Laboratory in Calif fuel dispenser ornia and Simon Hooker of Oxford University may offer the subject a way out. For Dr Leemans and Dr Hooker describe a fuel dispenser device that might cut costs drastically. Conventional accelerators use pulses of electrical energy to push sub-atomic particles (usually electrons or protons) to high speeds. The Leemans-Hooker device, by contrast, uses intense pulses of laser light. Unlike the LHC, which contains (if that is the right word) a vacuum and accelerates protons, it contains hydrogen and accelerates electrons. The hydrogen is in a narrow tube running through a block of artificial sapphire. First, the hydrogen is ionised by an electrical discharge. This not only separates the electrons and protons of which hydrogen atoms are composed, but also forces the resulting mixture, known as a plasma, towards the walls of the tube. That creates a channel through the plasma in the middle of the tube, and it is along this channel that the laser is fired. The passage of the laser beam knocks electrons out of the plasma remaining in the channel, because electrons are light. But protons, which are much heavier, are left behind. The result, since protons are positive, is that the laser pulse is followed along the channel by a pulse of positive charge, which in turn attracts electrons (which are negatively charged and therefore attracted to positive charges). Those electrons are thus accelerated rapidly. Other groups, it must be said, have tried this trick in the past. But they have not been as successful. The distinguishing feature of the Leemans-Hooker accelerator is the way that it stops the laser s light f fuel dispenser rom dispersing, and so keeps its intensity high enough for it
