ariable DC voltage. Diagram 3-9 is a drive circuit. The display mode of volume and sales on main display board adopt 6 digits liquid crystal display (Model ED-139, see Diagram 3-11), PPU or unit price r digits LCD (Model ED-830, see Diagram 3-12). Diagram 3-9: Static circuit and wave of LCD tube Diagram 3-10: Drive circuit of one-digit tube Diagram 3-11: ED-139 6-digit LCD Diagram 3-12: ED-830 4-digit LCD Display drive chip often adopts 8-digit memory/flip-latch: 74HC95. The drive circuit of liquid crystal display is composed of double D trigger 74HC74 and double input exclusive-OR gate 74HC86. Some fuel fuel dispenser dispensers adopt special crystal drive circuit in liquid crystal display, its principle basically similar to 74 series LCD drive circuit. A few fuel dispenser manufacturers adopt light-emitting diode (LED) as display components of display board because its cost is low and need not backlight in evening. The defect of this display component is bad display effect, especially under extensive sunlight, and much elect fuel dispenser ricity consumption. LED display drive circuit also has parallel and serial drive, similar to LCD display drive circuit in terms of structure. Very few fuel dispensers adopt matrix or color liquid crystal display, showing much information. However, it largely increases cost. 2.4 Power supply Stable voltage power supply used in explosion-proof fuel dispenser Most of fuel dispensers adopt explosion-proof type, installing liner stable voltage powe fuel dispenser r supply or switch voltage power supply. Switch voltage stabilizing power supply includes power transformer, DC/DC converter, 220V direct commute and pulse transformer, illustrated in Diagram 3-14 and 3-15. Due to cost-efficient and simple design, liner stable voltage power is widely adopted. However, it is affected by exterior network voltage. Although pulse transformer is able to tackle with network voltage fluctuation, it is can’t afford because of complicated technology, expensive cost and difficult to maintenance. In recent years, D

s not produce economic returns in the lifetimes of the administrations that fund the experiments, it is a fascinating endeavour. Over the past 100 years, physicists have succeeded in identifying the fundamental building blocks of the universe, both in terms of matter and of the forces that act on it. Yet the so-called Standard Model of particle physics, which weaves these discoveries together, and which has proved so successful to date, is incomplete. If physicists are to improve on it, they need machines that supply particles at higher energies to probe the nature of space and time. Such machines could provide answ fuel dispenser ers about how the universe began and how it will evolve. In this light, the NRC report makes interesting if somewhat biased reading. It wants America to retake the lead in particle physics, and to host the next new particle accelerator to be built after the LHC. A decision on whether to build this machine, dubbed the International Linear Collider, will not be taken until the initial results from the LHC are fuel dispenser known. If these point to more fundamental physics beyond the Standard Model, as is widely expected, then there would be mileage in building a more powerful accelerator to study these phenomena. Such a decision would not be made until 2010, but America s physicists are keen for their country to host such a facility. To do so, the NRC reckons, America will need to spend between 2% and 3% more each year in real terms on particle physics. That migh fuel dispenser t not sound onerous, but it amounts to $500m over the next five years. European particle physicists are also keen to lead the world. A similar panel of experts is close to finalising a European strategy. The CERN Council Strategy Group, as it is called, will meet near Berlin next week to hammer out a consensus. Then, in July, this consensus will be presented to the politicians who decide the funding of particle physics. At present, Europe is poised to take the lead it will soon have the world s biggest and best particle accelerat
