Granted: 2000-09-19
Abstract: The present invention provides a method and device for bringing the driven load of an internal combustion engine into motion by controlling the throttle or fuel delivery system of the engine and supplying a series of voltages to an electromagnetic clutch in a clutch engagement cycle. The throttle is set to a position or the fuel flow is regulated such that a specified torque output is produced by the engine. A detection means designates the time at which this output torque has been achieved. At this time, as designated by the detection means, a series of voltages is output to the clutch comprising a first voltage or voltage sequence to ensure engagement of the clutch, a second lower voltage to rapidly reduce holding torque to induce clutch plate slippage, a third voltage to maintain a desired rate of slippage, and a fourth voltage, preferably the rated voltage of the clutch, to lock the clutch plates together.

Title: Process executing method and resource accessing method in computer system
Inventor: SERIZAWA KAZUYOSHI

Filed: 1997-08-20
Granted: 2003-01-28
Abstract: A process executing method capable of performing multiprocessing by using a shared resource without impairing periodical drivability of processes designed for executing continuous media processing.  When a process requests the use of the shared resource, abortion of that process is first disabled by the process itself by using an abort disable function and then preemption of the same process is disabled by means of a preempt control module, whereupon the process enters a processing executed by using the shared resource.  Upon completion of the processing for the shared resource, the process is immediately set to a preempt-enabled state by means of a preempt control module.  After completion of all the processings, the abort-disabled state is finally cleared by using a disabled-abort clear function.  Upon occurrence of forcive termination of a process in the abort-disabled state thereof, execution of this process is continued until the abort-disabled state is cleared, and the process is terminated forcibly after the abort-disabled state has been cleared.

Abstract: A inexpensive and time saving method and system for reducing the use of gummed service stickers and the completion by hand of special forms for specialty mail is disclosed. This invention also reduces the amount of trips that have to be made to the post. The foregoing may be accomplished by replacing the standard (fixed) graphic cartridge that is normally supplied with a standard digital postage meter with an addressable "ram" image cartridge.          The addressable ram image cartridge may also be linked to a personal computer, where a program would allow the user to request specialty mail services. Once the desired service (services) are selected, the required postal graphic images are downloaded into the ram cartridge. Next, postal payment, if any, is totaled and the additional postal value is totaled and passed to the postal meter vault for totaling and printing in an accountable way. Finally, the personal computer meter or postage meter cycles normally first printing the indicia and then the graphics and bar codes as specified by each postal service that was selected by the user.

Abstract: An integrated circuit fuse with a fuse element having an "open" state and a "closed" state. A fuse status indicator is provided to indicate whether the fuse element is "open" or "closed". A current driver is electrically connected between the fuse element and electrical ground. One input of a dual input multiplexer is electrically connected to the fuse status indicator. The multiplexer's other input receives a fuse status simulation signal. A simulation mode switching signal is applied to the multiplexer's select input. A fuse output signal is consequently provided at the multiplexer's output to simulate operation of the fuse element in either the "open" or the "closed" state. The fuse element can be opened by causing a current having a value exceeding a preselected minimum value to flow through the fuse element for a preselected minimum time. This is preferably accomplished by fabricating the current driver as an NMOS device having a size sufficiently large to conduct the minimum value current for the minimum time required to open the fuse element. Advantageously, a pre-driver is provided to rapidly turn the current driver on, upon receipt of a fuse opening signal.

Title: Improved durability flame stabilizing fuel injector
Inventor: MORFORD STEPHEN A
IPC: F23R3/28
Filed: 1999-03-23
Granted: 2005-09-20
Abstract: The invention is a tangential entry, premixing fuel injector (10) for the combustion chamber (30) of a turbine engine. The injector includes a pair of arcuate scrolls (18) defining the radially outer boundary of a mixing chamber (28) and a pair of air entry slots (36) for admitting a stream of primary combustion air tangentially into the mixing chamber. The scrolls also include an axially distributed array of primary fuel injection passages (42) for injecting a primary fuel into the primary air stream. A  flame stabilizing fuel injector centerbody (46) includes an impingement and transpiration cooled outlet nozzle (50) for introducing secondary fuel and secondary air into the combustion chamber. The nozzle (50) includes an impingement plate(74) with an array of impingement ports (76) and a tip cap (104) with an array of discharge passages (106). The impingement ports and discharge passages are in series flow, misaligned relationship so that secondary air exiting from the impingement ports impinges on the tip cap and flows through the core discharge passages to impingement cool and transpiration cool the nozzle. The disclosed injector runs cooler than a more, conventional tangential entry injector and therefore is more durable. The improved durability is achieved even though the disclosed injector uses less cooling air than a more conventional tangential entry injector and discharges the cooling air at a lower velocity. The reduced cooling air quantity helps to minimize carbon monoxide emissions and the reduced discharge velocity improves the spatial and temporal stability of the combustion flame.

Title: Process for operating a blood centrifugation unit, as well as a centrifugation unit to carry out the process
Inventor: GEIGLE PETER
IPC: A61B90/00
Filed: 1997-10-24
Granted: 2004-03-23
Abstract: A process is disclosed for operating a centrifugation unit with a centrifugation container, in particular a centrifugation bowl, for separating the components of a liquid, in particular blood, containing components with different specific weights. The centrifugation container has a separation chamber, a liquid inlet into the separation chamber and an outlet for discharging the separated component from the separation chamber. The inlet and the outlet extend through a revolving passage at the upper end of the container. The inlet is in communication with an inlet duct which opens in a defined area of the container into the separation chamber. A pumping device is provided for filling and/or emptying the centrifugation container. The liquid to be centrifuged is supplied through the inlet. After a desired amount is separated, the flow direction between inlet and outlet is reversed while the centrifugation container continues to rotate at its full working speed, so that at least one of the separated components is discharged from the separation chamber through the inlet duct and the inlet. The flow direction is then reversed again, so that liquid to be separated is again supplied through the inlet. While the separated component is discharged, a compensating liquid is supplied through the outlet in communication with the separation chamber. Also disclosed is a corresponding centrifugation unit.
