Title: Method for reusing peeled wafer and silicon wafer to be provided for reuse
Inventor: KUWABARA NOBORU
IPC: H01L21/20
Filed: 1998-04-23
Abstract: PROBLEM TO BE SOLVED: To improve the productivity of an SOI(silicon on-insulator) wafer having an SOI layer with actually high quality, and to reduce costs, by providing a method for operating proper re-processing to a peeled wafer being a by- product in a hydrogen ion peeling method for actually reusing it as a silicon wafer, providing a method for reducing costs for the re-processing of the peeled wafer, and reprocessing an expensive wafer such as an epitaxial wafer many times for reusing this many times. SOLUTION: This is a method for adding re-processing to a peeled wafer being a by-product at the time of manufacturing an SOI wafer by a hydrogen ion peeling method for reusing this as a silicon wafer. In this case, this is a method for reusing the peeled wafer by operating at least grinding for removing a peripheral difference in step and heat-treatment under a reduction atmosphere containing hydrogen to the peeled wafer as the re-processing. Also, a silicon wafer to be provided for reuse can be obtained by this re-processing in this method.

Title: Matched filter
Inventor: MATSUI HIROFUMI
IPC: H04B1/7093
Filed: 1999-05-12
Abstract: PROBLEM TO BE SOLVED: To set other spread code from a spread code generating circuit in a short time in a matched filter where a correlation unit calculates correlation between a circulating spread code sequentially delayed in delay elements connected in a loop and a received spread spectrum code and a multiplexer selects an arithmetic result with all the spread codes and outputs the selected result so as to attain dump while continuously outputting the correlation arithmetic result. SOLUTION: The matched filter is provided with switches 17(n) each corresponding to each delay element 11(n) and with a spread code input selection circuit 18 that detects an end of the spread code by a dump code DMP and selects a proper switch. Thus, a new spread code is received from the proper switch immediately after a switching request of the spread code and the spread code can be set in the shortest time of one period.

Title: Method and device for conversion to pseuro stereophonic form
Inventor: KAKU JUNYA
IPC: H04S5/00
Filed: 1995-05-30
Abstract: PURPOSE: To obtain a pseudo signal by shifting the frequency of a voice signal to a high frequency side or a low frequency side and using each of an original voice signal and the voice signal shifted in frequency as voice signals of different channels. CONSTITUTION: The frequency of a monophonic voice signal MS is shifted to a high frequency side or a low-frequency side by a frequency shifting means A and the signal is defined as a voice signal S2R of a first channel. A delay means B delays the voice signal MS by the same signal delay as the delay by the processing of the frequency shifting means A and signal is defined as the voice signal S2L of a second channel. By reproducing the voice signals S2R and S2L of the first channel and the second channel by the speaker arranged on the right and left sides, for instance, a listener can obtain spreading feeling because the right and left reproduced voice is small in correlation with each other. When the shift amount of the frequency is made proportional to the size of the frequency of an original voice signal, more natural spreading feeling can be obtained.

IPC: H05B6/06
Filed: 1998-05-15
Abstract: PROBLEM TO BE SOLVED: To prevent operational interruption of an inverter as much as possible by turning an inverting circuit and the high frequency output off for an arbitrary time when the phase difference between voltage and current 15 smaller than a preset value and releasing turn-off after elapsing an arbitrary time. SOLUTION: Outputs from a voltage detection circuit 12 and a current detection circuit 13 are fed to a phase difference detection circuit 14 producing a signal corresponding to the phase difference between voltage and current. When the phase difference between voltage and current is smaller than a preset value, an inverting circuit 11 is turned off for an arbitrary time. High frequency output is turned off for an arbitrary time by turning off the high frequency output set signal from an error amplifier 24 for stabilizing the voltage or current of high frequency output and turn-off is released after the arbitrary time. Consequently, operation interruption of an inverter can be prevented as much as possible.
