ch is allowed to be operative switch, which should be connected with intrinsic safety power or dealt with explosion-proof. Diagram 3-23: Photoelectric switch circuit Simple as operative switch, the trouble of operative switch largely caused by incorrect mechanical position is very common. Article III IC card-controlled fuel disp fuel dispenser enser IC card-controlled fuel dispenser, just as its name implies, refers to a new kind of fuel dispenser that is conducted refueling with valid IC card, filling money being deducted from IC card after operation. As a new payment of refueling, the trouble of IC card accounts for a certain proportion. Thus, it is necessary to introduce IC card here. Filling IC card App fuel dispenser earance Filling IC card is same to finical IC card in terms of inner structure or appearance size, both complying with the standard of ISO 7816. The appearance of filling IC card is showed in Diagram 3-24. Surface size of IC card is presented in Table 3-1.

Inner structure of IC card chip Inner structure of IC card chip illustrated in Diagram 3-25 CPU: 8-digit microprocessor with 16-digit address bus (some with 16 MPU) COS memory: it is often used to store operating system of chip (COS--- Chip operation system). With enhance of COS function and CPU speed, the storage of COS become larger.

the second level of addressing is the subnet. A subnet is a logical　　 grouping of nodes from one or more channels. There may be up to　　 255 subnets per domain.　　 - the third level of addressing is the node. There may be up to 127　　 nodes per sub fuel dispenser net.　　 - group addressing facilities are not used.　　The Lontalk protocol offers four basic message services these being:-　　 ACKD REQUESTRESPONSE UNACKD_RPT UNACKD　　The service implemented on the IFSF network is ACKD. The ACKD service is were a　　message is sent to a node and individual acknowledgements are expected back from each　　 fuel dispenser recipient node. If the acknowledgements are not all received the sender times out and retries　　the transaction. The number of retries and the time-out value are variable and are set along　　with the network parameters by application level code (layer 7 OSI model) see below for　　par fuel dispenser ameter description and the values set in the IFSF network implementation:-　　FP2_1.84 IFSF STANDARD FORECOURT PROTOCOL February 2003　　 COMMUNICATION SPECIFICATION　　Page: 8　　Priority Slot:1 Determines if message has priority over other messages　　 improves response time of critical messages (set to 1 to　　 allow for the creation of emergency messages).　　Retry =3 Specifies the number of times a node will repeat sending　　 A messageif it doesn t receive an acknowledgement.　　RPT_Timer : Not used Specifies how frequently the message is repeated when　　 using unacknowledgedrepeated service.　　RCV_Timer: Not used Started when a node receives a message.　　TX_Timer = 96ms

fragile morale. Only 31% of respondents planned to vote for Labour, its lowest rating in 19 years, while 40% said they would vote Conservative, the party s strongest showing in 14 years and enough to secure a narrow election victory. Just as dismaying, on almost every measure of personal economic well-being voters thought they wer fuel dispenser e worse off than when Labour came to power in 1997. Among the MPs keenest for Mr Blair to announce his exit date are those with marginal constituencies in highly taxed London and the south-east, which they fear are vulnerable to the appeal of David Cameron s reviving Tories. Above all, however, there is frustration over the sense of drift caused by the expectation, bu fuel dispenser t not certainty, that Mr Blair will quit soon after his tenth anniversary as prime minister next May. Only the most reckless can see advantage in forcing him to go sooner. But though nearly everyone claims to want a smooth transition from Mr Blair to Mr Brown, waiting for it to happe fuel dispenser n, says Don Touhig, a former minister, is “bleeding the Labour Party at its heart� Mr Brown, although seething with impatience, understands precisely how dangerous the situation is both for himself and for the government. That is why he has kept so quiet during an eventful August and why, despite the encouragement of his admirers, he will resist the temptation to start explaining what a Brown administration would look like. The chancellor s more naive supporters yearn for him to demonstrate the ways in which he will differ from Mr Blair. The prime minister, on the other hand, would like him to commit himself unambiguously to a version of New Labour that is indistinguishable from his own. Mr Brown judges neither course to be in his or the party s interest at the moment. The key to whether Mr Brown inherits a party divided by faction lies in the behaviour over the next few months of Blairite loyalists. On that score, he has grounds for hope. Stephen Byers, a former minister who likes to be known as an “o
