Title: Exposure apparatus, exposure method and manufacturing method of device
Inventor: MURAKAMI SEIRO
IPC: G03F7/20
Filed: 1998-11-23
Granted: 2001-08-01
Abstract: In this invention, under the state that the illuminating light from the illuminating optical systems IOP1, IOP2 is irradiated on the mask of the mask stage RS1 and the mask of the mask stage RS2, respectively, the mask stage RS1 is made to move synchronously with the substrate stage WS1 and the mask stage RS2 is made to move synchronously with the substrate stage WS2. In addition, by moving the mask stage RS1 and mask stage RS2 in the directions opposite to each other, the reacting force for the chassis 18 caused by the movement of stage can be canceled out so as to suppress the vibration of the exposure apparatus. Additionally, by conducting the calibrating actions onto the substrate stage WS3, WS4 at the same time as that of performing these exposure actions, the production capability can be improved.

Title: Silence compression for recorded voice messages
Inventor: ALI SYED S
IPC: G10L19/02
Filed: 1998-11-24
Granted: 2000-08-11
Abstract: A silence compression system that improves data compression in a digital speech storage device, such as a digital telephone answering machine, without undue clipping of voice signals. Instead of employing only real-time compression, the inventive silence system analyzes and compresses or recompresses digital speech samples stored previously, when the voice messaging system is off-line or otherwise in a low priority state. A method of silence compression comprises receiving real-time speech samples, storing the same in memory, and analyzing the stored speech samples at a later time to determine thresholds for periods of silence. The periods of silence are then compressed, and the silence compressed voice message is restored in memory. In this fashion, the processor is not required to make a silence period determination on-the-fly simultaneous with encoding and compression of the real-time voice message, and thus is not subjected to heavy processor loads typically encountered in real time. This enables more efficient compression of speech samples, lighter duty processors, and improved voice quality upon reproduction by eliminating undesired clipping of the voice signal encountered in prior systems after periods of silence. The silence compressed speech samples are stored in a storage device for subsequent playback.

Title: Suspension type hoist
Inventor: NAKAGAWA SUSUMU
IPC: B66C13/06
Filed: 1999-02-25
Granted: 2004-01-01
Abstract: This invention provides a suspension type hoist. To greatly enhance an operation efficiency by effectively preventing an elevation part from rocking, in this invention, a positioning means positioning suspended material in a horizontal plane is set up in a place between a moving dolly and the suspended material. The rocking speed of an elevator part hung down from the suspended material is detected by a rocking speed detecting means. The positioning means is controlled by a position control loop, a speed control loop and a rocking retaining compensation means, wherein the position control loop outputs a speed command based on deviation between a position target value and an actual position, the speed control loop outputs a thrust command based on deviation between the speed command and an actual speed, and the rocking retaining compensation means outputs a damping signal based on the rocking speed of the elevator part, which is outputted from the rocking speed detecting means, and makes addition to the thrust signal after the damping signal is reversed in phase.

Title: Bus interface for transferring a signal over a bus and method of transferring a signal over a bus
Inventor: SEOK YONG-SIK
IPC: G06F13/40
Filed: 1999-04-15
Granted: 2001-09-11
Abstract: A bus interface system and method includes a driver circuit and a receiver circuit coupled on opposite ends of a conducting line of a bus. The driver circuit drives an adjustable current through the conducting line to the receiver circuit. The current level of the adjustable current can be adjusted to one of several levels according to the data item being transferred across the line. The receiver circuit receives the adjustable current and detects the level of the current to identify the information encoded by the signal being transferred. The current level can be set to one of several values such that the information being transferred by the signal can be in one of several possible states. The system therefore is capable of encoding more data than binary systems. Higher data bus transfer rates can therefore be realized.

Title: Radio communication system
Inventor: BAKER MATTHEW PETER JOHN
IPC: H04B7/26
Filed: 2000-05-31
Granted: 2002-07-01
Abstract: In a radio communication system having a primary station and a plurality of secondary stations, the power of uplink and downlink channels between the primary station and a secondary station is controlled in a closed loop manner by each station transmitting power control commands to the other station. In response to these commands the receiving station adjusts its output power in steps. By considering a plurality of received power control commands the receiving station may emulate the ability to use power control step sizes other than those it directly implements, for example step sizes smaller than its minimum or intermediate between implemented step sizes. Performance can thereby be improved under certain channel conditions. In one embodiment when the required power control step size is less than the minimum step size of the receiving station, that station processes a group of power control commands to determine whether to adjust its output power by its minimum step size.

Title: Wafer retaining device
Inventor: NAKAI TETSUYA
IPC: H01L21/687
Filed: 2000-08-31
Granted: 2002-11-21
Abstract: A wafer-retaining device is provided. Put the wafer (22) on the surface of the retaining device body (23). The retaining device body is inserted into a fillister for plural retaining devices (14), which is formed by a thermal process furnace and is kept horizontally. The retaining device body is made to be a round plate without breaches. The body also has a ring type extrusion (24) that extends in the radial direction (by using the body axis as center) and extrudes in the upper direction. The wafer touches the extrusion and is carried on the retaining device body. If the diameter of the wafer is D, the outer diameter of the extrusion is fallen in the range 0.5 D to 0.98 D to let the edge of the wafer not touch the extrusion. By controlling the twist of the retaining device body during fabrication, the slide of the wafer is suppressed. The retaining device can retain the wafers with different diameters in fixed site. Besides, the operation of loading/unloading wafer from the retaining device is also smoothly executed.
