s to quickly switch off power supply circuit in case that the associated circuit, connected power and used in explosive gas atmosphere, generate spark or become hot due to short circuit. Therefore, a reliable and valid safety barrier is very important to intrinsic safety fuel dispenser. The traditional safety barrier, adopting diode safety barrier, current fus fuel dispenser e, voltage stabilizing diode and limited current resistance, is difficult to applicable to simple fuel dispenser due to expensive cost, large cubage and long time of melt. Owing to reliable performance, cost-efficient, quick response, electric safety barrier adopted VMOS component is widely mounted in most fuel dispenser at home and abroad.

At present, there are two kinds of popular pulse sensors in domestic market. One has double-way 30 pu fuel dispenser lses as per rotation of flow meter, the other double-way 50 pulses per rotation. Pulse sensor includes photoelectric sensor and Hall-effect Sensor. The circuit of popular photoelectric sensor is illustrated in Diagram 3-21 and 3-22. With the development of integrated circuit, a new kind of optical coupler is created, collecting the outside section of optical couple into inner so as to be simpler to use. Diagram 3-21: Photoelectric sensor circuit I Diagram 3-22: Photoelectric sensor circuit II 2.7 Operative switch Most manufacturers install operative switch on keyboard of fuel dispenser, though simple to technical solution, especially in preventing dangerous area in where install switch, the life service of keyboard is unable to be ensured due to so frequent operation. Therefore, the best solution is to install a touch switch on nozzle bracket. Mechanical key swit fuel dispenser

Chernin, the group s chief operating officer, would take over. Meanwhile, Mr Murdoch has failed to see off John Malone, boss of Liberty Media, whose 18% voting stake is not far off the 29.5% that the Murdochs collectively own. In 2004, to the dismay of shareholders, News Corporation s board agreed to a poison-pill defence to prevent Mr Malone buying more v fuel dispenser oting shares. Eventually, Mr Murdoch hopes to overcome the impasse by buying back Mr Malone s shares in return for one or more of the group s assets. “We re waiting on him to come up with a scheme that will satisfy his tax issues,�Mr Murdoch says. He rejects the possibility that Mr Malone intends to grab control of News Corporation. “He s a great financial engineer, but he doesn t have the management,�Mr Murdoch says. For the moment, News Corporation intends to keep its poison pill, even though investors dislike it. News Corporation argues that senior people at big fund-management firms do not have a big problem with the poison pill, and that it is only corporate-governance specialists who are making a fuss. Perhaps, but the company would doubtless like more fund managers fuel dispenser to buy its shares. Many will not do so until the poison pill is gone and there is clarity about who will end up in charge. © 2006 . Emerging economies Climbing back Jan 19th 2006 From The Economist print edition The economies of what used to be called the “third world�are regaining their ancient pre-eminence SINCE their industrial revolutions in the 19th century, the rich countries of the “first world�have dominated the global economy. By one measure at least, that era may be over. According to estimates by The Economist, in 2005 the combined output of emerging (or developing) economies rose above half of the global total. This figure has been calculated from the International Monetary Fund s World Economic Outlook database. We have adjusted the IMF s numbers in two ways. First, we have taken account of China s fuel dispenser
