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 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 electricity 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 power 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 fuel dispenser 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.

ot available any attempt to release a fuel pump should be　　 rejected with a Data ACK of 6.　　 If the FP is assigned to a CD the FP can only be released by the CD that assigned it.　　 Any fuelling limits and grade masks must be transmitted to the FP before the　　 Release_FP command is transmitted. The release could be done without any limits　　 with a volume limit (preset mode) or an amount limit (prepay mode).　　 If there are is no unit price available any attempt to release a fuel pump should be　　 rejected with a Data ACK of 6.　　 A Release command will be rejected if the customer has removed an invalid nozzle　　 i.e. one not permitted in the grade mask (FP Data Base Data_Id 25　　 Log_Noz_Mask). If this situation occurs the dispenser will reject the Release　　 command with a Data_ACK value of 6 (Command not accepted).　　 The FP receives a release and the FP moves to the STARTED state.　　 It is also possible to release a FP locally by a sales assistant (on attendant operated　　 FPs).　　 PCD Comment:　　 As most proprietary FP s only allow one transaction at a time the PCD will have　　 to manage multiple transaction itself (assuming that the PCD supports more than 1　　 transaction buffer).　　 As most proprietary FP s don t support assignment the PCD will have to manage　　 the assignment regulations itself.　　 Where the proprietary FP protoc fuel dispenser ol doesn t indicate the selected nozzle the PCD　　 will have no choice but to ignore the Log_Noz_Mask and release the FP.　　 Action : Fo fuel dispenser fuel dispenser

h should come entirely or mainly through donations rather than through taxation. What should worry the parties still more is that it emerged from focus groups that few people had more than the haziest notion what they contributed to democracy or why they needed money to function. Sir Hayden Phillips, a retired senior civil servant appointed by the prime minister last week to look into party financing, will complete his report later this year. Sir Hayden is almost certain to recommend some modest form of state funding linked to votes cast in elections and party membership rolls. After haggling over the details, Mr Blair and Mr Cameron will jump at it. The hard part will be convincing suspicious and bloody-minded voters that it is in their interests too. © 2006 .  About sponsorship Coming out Mar 23rd 2006 From The Economist print edition AP China hopes to use the 2008 Olympics in Beijing to mark its emergence on the world stage. But, says James Miles (interviewed here), it still has plenty of things to fix at home Get article background “CHINA is a second-rank middle power that has mastered the art of diplomatic theatre it has us willingly suspending our disbelief in its strength.�So argued the late Gerald Segal, a British scholar, in 1999 as the country reeled from the Asian financial crisis and fumed impotently as NATO attacked Serbia. China was then merely “a theoretical power� and seriously overrated in terms of international trade and investment. Mr Segal made a powerful case that China mattered far less than many believed. Today it is hard to dispute that China matters far more tha fuel dispenser n it did seven years ago. Yet there is no other important country whose likely trajectory over the next 20 years is more uncertain than China s.
