Filed: 1994-11-29
Granted: 1998-08-25
Abstract: A fuel injection amount control system for an internal combustion engine includes an ECU which calculates a first amount of fuel directly drawn into each combustion chamber out of an amount of fuel injected into the intake passage via a corresponding fuel injection valve, a second amount of fuel carried off fuel adhering to the wall surface of the intake passage into the combustion chamber, and an amount of fuel to be injected into the intake passage, based on the first fuel amount and the second fuel amount, calculates an air-fuel ratio correction amount, based on an output form an air-fuel ratio sensor arranged in the exhaust system, and corrects the amount of fuel to be injected into the intake passage by the air-fuel ratio correction amount.  Further, the ECU corrects the second fuel amount, based on the air-fuel ratio correction amount.

Abstract: A distributed file system uses objects to model the behavior of components of the distributed file system. Each object has an associated logical path name and physical address. An aggregation of all the logical path names comprises a distributed name space which can be logically partitioned into domains. Each domain includes a domain folder object which maps logical path names of objects in the domain containing the domain folder object, into addresses in the distributed system where the objects are stored. The addresses of the objects are used to access the objects in order to retrieve information from the distributed system.

Title: Method for accessing banks of dram
Inventor: JONES ANTHONY M
IPC: G06F17/30
Filed: 1995-03-23
Granted: 1999-04-27
Abstract: This invention discloses a method for accessing Dynamic Random Access Memory (DRAM) to store and retrieve data words associated with a two dimensional image.  The DRAM includes two separate banks, a first bank and a second bank.          Each bank is capable of operating in page mode to read and write the data words.  The two dimensional image is organized in a two dimensional grid pattern of cells, each cell containing an M by N matrix of pixels.  The words associated with each cell occupy one page or less of a bank.  Each cell is assigned a particular one of the two banks so that all data words associated with that particular cell are read from and written to one particular page of that particular bank.  The assignment of banks to cells is done such that each cell is associated with a different bank than any bordering cell which is also either in the same row or in the same column.  There is then read the data words associated with a cell that is composed of a matrix of pixels and is not aligned with the two dimensional grid pattern, but is aligned with pixels in cells in the two dimensional grid pattern.

Granted: 2005-09-20
Abstract: The description relates to a process and device for transferring prints (18, 20) from a support (16) to a substate (10) in which the support (16) is conveyed together with the substrate (10) through a station in which copies (18, 20) are applied in register on the substrate (10) which has successive sheets (12). Here, use is made of a substrate (10) having at least two adjacent rows in the direction of transport of sheets (112) and of a support (16) which, in the direction of transport between the prints (18) for successive pages (12) in the direction of transport, has at least one additional print (20).  According to the invention, there are means by which only certain prints (18, 20) can be selectively transferred from the support (16) to the substrate (10) in the station. After leaving the station, the support (16) is released from the substrate (10) and, depending on the number of successive sheets (12) between two prints (18) in the direction of transport for successive prints (18) in the direction of transport, taken to the station at least once more, the support (16) being shifted sideways by the transverse distance between the neighbouring rows of sheets and by about the distance between directly successive prints (18, 20) is the direction of transport.

Title: Cryogenic fluid pump and tank apparatus and method
Inventor: GRAM ANKER
IPC: F04B19/06
Filed: 1994-03-29
Granted: 1999-08-10
Abstract: Cryogenic fluid piston pump functions as stationary dis-pensing pump, mobile vehicle fuel pump etc., and can pump vapour and liquid efficiently even at negative feed pressures, thus permitting pump location outside a liquid container. Piston in-ducts fluid by removing vapour from liquid in an inlet conduit faster than the liquid therein can vaporize by absorbing heat, and moves at essentially constant velocity throughout an induction stroke to generate an essentially steady state induction flow with negligible restriction of flow through an inlet port. Stroke dis-placement volume is at least two orders of magnitude greater than residual or dead volume remaining in cylinder during stroke changeover, and is greater than volume of inlet conduit. Cryo-genic tank has a liquid compartment, a vapour compartment, and inlet and overflow conduits. Inlet conduit receives liquid from dispensing pump and widely disperses liquid into liquid tank to contact and condense vapour. Overflow conduit restricts flow of excess liquid from liquid compartment to vapour compartment. Excess pressure in tank or temperature of overflow liquid from conduit is detected to automatically stop dispensing pump. As a fuel pump, the pump selectively receives cryogenic liquid and vapour from respective conduits communicating with tank, and pumps cryogenic liquid to satisfy relatively heavy fuel demand of engine, which, when satisfied, also pumps vapour to reduce vapour pressure in the tank while sometimes satisfying relatively lighter fuel demand.

Abstract: Initially storing multimedia messages from an originating communication terminalto a destination communication terminal on the destination communication terminal. If the destination communication terminal cannot store messages, then the message is stored on the originating communication terminal. The destination communication terminal may not be able to store messages because it no longer has present message storage facilities on an internal storage unit or it does not have any internal storage capability for messages.  Similarly, the originating communication terminal also may have exceeded its capacity to store messages or may not have any internal storage devoted to the storing of messages.  The destination communication terminal maintains a list of messages that are stored on other communication terminals.  In addition, if the originating communication terminal cannot store messages, a message is stored on a third terminal which has the capacity to store messages. The messages stored on the third communication terminal are encrypted to protect the privacy of users of the originating and destination communicationterminals.

Abstract: A method and a circuit for simple clock recovery from multi-level at high transmission rates. The circuit is compatible with standard PLL-type clock recovery techniques for NRZ and generalized two-level signalling.

Abstract: The accumulation of lint, debris and other contaminants in the needle and dial slots of a circular knitting machine can be significantly reduced by enclosing an annular air chamber spanning between the cylinder and dial and delivering a pressurized airstream into the chamber. The airstream can necessarily escape from the chamber only upwardly through the spacing between the cylinder and dial where the airstream serves to blow lint, debris and contaminants away from the critical knitting elements (e.g., needles and sinkers) and prevent the accumulation of such materials within the cylinder and dial slots. The conventional need for flushing the cylinder slots can be reduced or eliminated.
