Patent TW-425783-B (TW)
Title: A method to mitigate the near-far fext problem
Inventor: JACOBSEN KRISTA S
IPC: H04B3/32
Filed: 1999-07-07
Granted: 2001-03-11
Abstract: The present invention provides methods and apparatuses for reducing near-far cross-talk interference between channels in a communication system. Channels (L1-Ln) of different lengths (d1n-dn) that are disposed adjacent to each other and carrying signals at the same frequencies often time create cross-talk interference in their neighboring channels. By spectrally shaping the signals carried on shorter lines the amount of cross-talk interference generated by these lines to longer lines may be significantly reduced, resulting in a better overall performance. In one embodiment of the present invention, a method of reducing the generation of near-far cross-talk interference includes spectrally shaping a signal carried on a first channel to reduce the amount of cross-talk coupling a neighboring second channel. In further embodiments, the shaping of the signal carried on the first channel is based in part on characteristics of the second and/or first channel. The characteristics include, but are not limited to, the length of the channels and the transfer functions of the channels. The present invention, in alternative embodiments, may also be embodied in a communication system, a central unit and a transceiver (or remote unit) or other suitable types communication devices that are capable of shaping transmissions to reduce cross-talk interference generated by the transmissions.

Title: Laser interferometer, position measuring device and measuring method, exposure device and manufacturing methods thereof
Inventor: TSUCHIYA MAKOTO
IPC: H01L21/027
Filed: 1999-08-05
Granted: 2000-06-01
Abstract: The present invention provides a laser interferometer for measuring the Y-direction position of the moving object while moving in X direction that comprises a separated optical system moving with different speed from the moving object along the X direction. The laser beam is separated into reference beam and measurement beam by means of the separated optical system and those beams are incident on the reference lens and moving lens of the moving object respectively. Then, the reflected beams from the moving lens and the reference lens are received by the light measurement device through the separated optical system; and the photoelectric conversion signal of said interference light is outputted as the information of Y-directional position. Because the separated optical system also moves along the X direction, it is enough to use the fixed lens having shorter length than the moving object.

Title: Computer system with power management scheme for DRAM devices
Inventor: BENN SAMUEL D
IPC: G06F1/32
Filed: 1999-10-28
Granted: 2001-07-11
Abstract: A computer system employs DRAM devices in a memory sub-system, which devices are assigned into particular pools corresponding to different power consumption states with a most-recently-accessed (MRA) device being assigned to an active pool and placed at the top of a stack structure. A LRA device in the active pool is evicted from the active pool and placed in a standby pool when the active pool is full and the processor accesses another device, which is not currently assigned to the active pool. A LRA device of the standby pool gets evicted into a nap pool upon one of two conditions: either a timeout occurs, or the standby and active pools are full and the processor accesses another device, which is not currently assigned to either the active or standby pools.

Title: Circuit driver on SOI for merged logic and memory circuits
Inventor: LATTIMORE GEORGE MCNEIL
IPC: H01L27/088
Filed: 2000-02-29
Granted: 2001-09-11
Abstract: A silicon-on-insulator digital circuit combination having a body voltage control stage and a voltage clamp stage. The body voltage control stage is responsive to an input control signal to provide an output driver signal. The body voltage control stage has a first transistor with a terminal for electrically-coupling to a combinational logic circuit, and a body contact electrically-coupled to the input control signal such that a threshold voltage of the transistor is reduced when the transistor is placed in an active state. It can be readily appreciated that the reduced threshold voltage of the transistor increases the transition rate for the first transistor to an inactive state in response to the input control signal. The voltage clamp stage has a second transistor responsive to the input control signal such that the terminal is electrically-coupled to a reference voltage when the first transistor is in the inactive state.

Title: Micro-positioning device for micro electric discharge machining
Inventor: SHIE JUNG-YOU
IPC: B23H1/00
Filed: 2000-03-31
Granted: 2003-04-11
Abstract: The present invention relates to a micro-positioning system for micro electric discharge machining, comprising a machine frame, a worktable, an electrode holder, an electrode, a spindle driving motor, an X-axis driving member, a Y-axis driving member and a Z-axis driving member and a control unit. The X-axis driving member, the Y-axis driving member and the Z-axis driving member each comprise a driven element driven by an electrical power source. A shock absorbing member formed of high molecular electrorheological material is attached to an end of the driven member and a fine adjusting member formed of piezo-electrical material is attached to an opposite end of the driven member. An end of the fine adjustment member is attached to the worktable. When the control unit applies no current to the shock absorbing member, the molecules of the shock absorbing member show irregular arrangements of positive and negative poles thereof, leading to the effect of slightly liquidized (namely softened), which demonstrates characteristics similar to a shock absorber whereby the shock caused by positioning the worktable to predetermined location is minimized quickly, realizing the function of shock absorption. By having the control unit applying a voltage of desired volts to the fine adjustment member made of the piezo-electrical material, the characteristics of piezo-electricity of the material makes the fine adjustment member extend a desired distance in approximately super-sonic speed thereby realizing fine adjustment of positioning.
