A Section and B Section are the neared vane, which rotate together with rotor clockwise. The turning Vane A increases the cubage of low pressure transitional area, oil being sucked into pump. Fuel between vane A and Vane B is brought to high pressure transitional area as the vane go around clockwise. In high pressure transitional area cubage become smaller because of vane rotation, as result, oil is impelled out under the vane pressure. When rotor turns continually oil in tank is sucked into pump and then discharged out ceaselessly to form a stable flowage. Pump flowage formula is showed in Diagram 2-1.

    evice type.   A list of all valid Subnet addresses is given in Engineering Bulletin Number 8.   N: All devices belonging to the same Subnet (so having the same type) are   identified by a unique Node address (N). The values are 1 to 127.   Please note that the SubnetNode assignments must be implemented at the Application   level. However to allow multiple devices to be interfaced via a single Echelon  fuel dispenser Neuron chip (i.e. An OPT that consists of a PIN Pad Card Reader Receipt Printer   Journal Printer) it is permitted to use a different SubnetNode address in the   application message than the actual network Neuron chip SubnetNode address.   Example:   When addressing a PIN Pad (S4:N1) that is connected to an OPT device with its   Neuron chip configured as (S6:N1) the Transmitting Neuron chip will transmit at   network level to the OPT device (S6:N1) but in the application message will use a   Recipient Subnet address of 4 and a Recipient Node address of 1.   Where: S4:N4 = S4 is Subnet 4   fuel dispenser N1 is Node 4.   It is therefore up to the application layer to decipher the incoming message and then   route the data to its respective device.  4.2 Application Protocol Parameters   - Block Length:   The Block Length is set by the Max_Block_Length communication data element.   The range for the block length is 32 to 228. To allow messages longer than this value   a Block Number BL is included in the message.   The preferred range for the Block Length is 32 to 228 but it is recognised sometimes   this is not practical. Therefore it is acceptable to implement a maximum Block Length   smaller than 228.

    rmation-technology triumphs. Competition is emerging, but “the opportunity is so large? that things seem set fair for the next five years at least. Kohlberg Kravis Roberts (KKR), most famous of American private- equity firms, seems to share his optimism. On April 16th it announced it was buying 85% of FSS from its owners, Flextronics, a contract manufacturer for the electronics industry, with its headquarters in Singapore. The price?600m in cash with a further $250m fuel dispenser plus interest due in eight years time—make this one of the largest deals yet in India s IT industry, and the biggest leveraged buy-out by a private- equity firm operating in India. In recent months there have been a number of takeovers of both IT firms and of those in the broader area of remote back-office services (“business process outsourcing? or BPO). Last August Oracle, an American software giant, bought control of i-flex, India s largest exporter of software products—in its case, banking systems. In March RR Donnelly, a big American printing firm, agreed to buy OfficeTiger, a Chennai-based BPO firm, for a reported $250m. These deals and KKR s purchase illustrate three trends. First is the expected growth of IT- outso fuel dispenser urcing and BPO. Mr Kumar estimates that, just in FSS s niche—sophisticated software for the communications industry—there is a potential market of $100 billion a year, of which so far only $2 billion is being outsourced. His firm, which had 90 people in 1995, now has 6,100, 85% of them in India. Second, this optimism about business prospects is being translated into valuations that make suitors hard to resist. Third is the recent availability in India of the huge resources of private-equity firms, looking for a home. This is KKR s first investment in India, although last year, in what it describes as the largest private-equity investment in history in a technology firm, it was part of a consortium that acquired SunGard, a big financial-software firm, which, like most such companies, fuel dispenser
