Title: Digital signal processor
Inventor: MORI KOICHI
IPC: G06F9/38
Filed: 1999-06-29
Granted: 2001-06-16
Abstract: The present invention relates to a digital signal processor, especially to a digital signal processor for reducing the number of processed commands while executing condition commands. The object of the present invention is to reduce the number of commands in the program having condition executing command. In the solution means, when the digital signal processor performs the pipeline process with three stages, such as command reading period, command decoding period and command executing period, and decodes the condition executing command with command decoder 14, it is assumed that the condition is consistent in putting the value of register A on the data bus. During the command executing period of condition executing command, the register B will take the value on the data bus only when the condition is consistent. Therefore, the condition generated by the command is executed during the command executing period, even before the changing of conditional code flag Z. It can decode the condition executing command to eliminate the commands such as ""condition generating command or conditional executing command"" required in the conventional necessary.

Title: Load balancing cooperating cache servers by shifting forwarded requests
Inventor: JORDAN KEVIN MICHAEL
IPC: G06F9/50
Filed: 1999-10-07
Granted: 2001-07-01
Abstract: In a system including a collection of cooperating cache servers, such as proxy cache servers, a request can be forwarded to a cooperating cache server if the requested object cannot be found locally. An overload condition is detected if for example, due to reference skew, some objects are in high demand by all the clients and the cache servers that contain those hot objects become overloaded due to forwarded requests. In response, the load is balanced by shifting some or all of the forwarded requests from an overloaded cache server to a less loaded one. Both centralized and distributed load balancing environments are described.

IPC: H01L21/76
Filed: 1999-12-09
Granted: 2001-05-16

Therefore, the present invention has an application potential in the future damascene of copper wire/low dielectric constant (low-K) dielectrics.

Title: Projection display device
Inventor: KUROSAWA SHOGO
IPC: H04N5/74
Filed: 2000-02-15
Granted: 2003-03-01
Abstract: The present invention aims to provide a projection display device that not only allows easy change of light source and, at the same time, has excellent cooling efficiency but also impels miniaturization. By being installed on a replaceable cap (502), an exhaust fan (16) adjacent to a light bulb (181) can be taken off together with the replaceable cap (502) from the main body of the projection display device (1). Thus, it only needs to take the replaceable cap (502) off to easily mount or dismount the whole unit (8) containing the light bulb (181) through a space (504). Also, while no extra special space is required for sliding of the unit (8), other components, apart from the exhaust fan (16), can be installed adjacent to the periphery of the unit (8) so that the device (1) can be further miniaturized. Moreover, since the exhaust fan (16) is adjacent to the unit (1) once the replaceable cap (502) is shut, the light source (183) in the unit (8) can be cooled down efficiently.

Title: High-speed digital timing and gain gradient circuit employing a parallel architecture
Inventor: STASZEWSKI ROBERT B
IPC: H03H17/02
Filed: 2000-03-01
Granted: 2001-10-01
Abstract: A system and a method for implementing a feedback control signal by employing parallel paths (105 and 106) for processing separate parts of the signal. The method effectively doubles operating speed of the feedback circuit by providing two processing paths (101 and 102). Where two paths are used, each operates at approximately one-half of the data rate of the incoming data signal (516). The method also lends itself to processing in those applications where more than one mode is used. For example, when used in a read channel (513) of a disk drive (500), three modes are desired: FIR-bypass (201), acquisition (202), and data-tracking (203). Being able to switch easily among the three modes of the system (200) provided for in a read channel of a disk drive (500) demonstrates the adaptability of the method and supporting structure to a broad class of feedback circuits used in systems employing high throughput rates.

Title: Enhanced method of closed vessel combustion
Inventor: ISAKSEN KJELL
IPC: F02B53/00
Filed: 2000-06-01
Granted: 2001-12-11
Abstract: In a spark ignition (SI) turbine engine, the combustible fuel-air mixture is compressed by volume displacement and accelerated at high velocity into the ignition source, to reduce the combustion time relative to conventional SI engines, lowering the lean fuel-air mixture flammability limit. Increased process velocity reduces the time exposure of the compressed fuel-air mixture to combustion, permitting near adiabatic operation without preignition. Reducing the time exposure of the combustible gases to high combustion temperatures may reduce emission of oxides of nitrogen. The best power combustion velocity may be maintained throughout the fuel-air mixture range. Lean fuel-air mixture operation may result in fuel savings without a corresponding loss of power, and may reduce carbon dioxide emissions. The high speed operation may provide a quieter engine. An expander or a turbine may recover some of the exhaust energy loss associated with near adiabatic combustion.
