Patent JP-H0884365-A (JP)
Title: Interference avoiding method
Inventor: KAKINUMA KAZUHIKO
IPC: H04W16/14
Filed: 1994-09-12
Abstract: PURPOSE: To attain installation and operation of a mobile communication system with less available channel resources having high possibility of causing interference with the surrounding service area. CONSTITUTION: A base station C is busy with a mobile station D and receives an incoming signal H from the mobile station D but receives the effect of an incoming signal F sent from a mobile station B of a peripheral system for the communication with the base station A and interference I takes place. In this state, an outgoing signal becomes a signal K by increasing the transmission output by the base station C up to a maximum value (figure J). Thus, the interference L takes place in the reception of the outgoing signal from the mobile station B. Since a channel is switched between the mobile station A and the mobile station B due to the interference L, the radio wave F being a cause to the interference I goes not give effect onto the radio wave H and then the interference I is avoided.

Title: Pulse rader
Inventor: HAMATSU KYOSUKE
IPC: G01W1/00
Filed: 1988-08-31
Abstract: PURPOSE:To expand the width of a maximum speed to be measured in a high elevation angle range by changing pulse repeating frequency correspondingly to a change in the elevation angle. CONSTITUTION:An elevation angle range to be scanned is divided into plural areas 1 to 4 and pulse repeating frequency levels F1 to F4 are set up correspondingly to respective areas 1 to 4. Since the repeating frequency levels can be increased in proportion to the elevation angles, F1<F2<F3<F4 is set up. On the other hand, maximum speeds to be measured can be increased in proportion to respective frequency ratios. In order to obtain changes in the repeating frequency levels, a pulse repeat control signal 9 is changed by a trigger controller 8 correspondingly to an elevation angle signal 10 and a trigger pulse 5 is generated by a trigger generator 4 on the basis of the control signal 9.

Title: Silicon carbide semiconductor device and manufacture thereof
Inventor: YAMAMOTO TAKESHI
IPC: H01L21/04
Filed: 1998-07-31
Abstract: PROBLEM TO BE SOLVED: To prevent the inversion of a conductive type of an n type channel formation region due to B(boron) diffusion. SOLUTION: B ion implantation is carried out into an n- type epitaxial layer 2, and then the layer is subjected to an annealing operation to activate B and to form a p-type base region 3. And a surface part of the epitaxial layer 2 is reactively ion-etched(RIE) down to a high B concentration to have the base region 3 exposed. Thereafter the epitaxial layer 2 is subjected to sacrificial oxidation and an oxide film formed by the sacrificial oxidization is removed to eliminate the damages by the RIE. The sacrificial oxidization step causes the regions 3 and 2 to have good surface crystallization. Thereby, even when a surface channel layer 5 is formed on the base region 3, it can be avoided that B does not diffuse into the surface channel layer 5.

IPC: C12R1/19
Filed: 1993-09-02
Abstract: PURPOSE:To enable efficient accumulation of an objective substance with reduced accumulation of acetic acid by culturing a microorganism belonging to Escherichia, by increasing the intracellular expression of the gene of a specific protein effectively suppressing the accumulation of acetic acid and collecting the objective substance accumulated in the medium. CONSTITUTION:Escherichia coli cells are cultured to collect wet cell bodies from the culture mixture and chromosomal DNA is isolated from the cell bodies by a usual manner. The DNA is treated with a restriction enzyme to be linked to a vector to prepare a gene library, which is cloned to isolate an acetic acid- assimilating gene (ace). The acetic acid-assimilating gene is linked to a vector together with the gene coding the objective substance to prepare a multi-copying type expression vector. Then, the vector is inserted into a microorganism of Escherichia coli to effect transformation. The transformant is cultured in a medium to increase the intracellular concentration of Ace protein having a specific amino acid sequence as a product of the ace gene and suppress the acetic acid accumulation. Thus, the objective substance is accumulated in the culture and collected to result in efficient production of the objective substance.

Abstract: PURPOSE:To stabilize the welding quality by arranging a DC voltage detection means of a welding electrode and a setting means of the constant voltage and comparing the DC voltage and the set voltage between the electrodes to control the pulse width of a high-frequency coil. CONSTITUTION:A voltage detection circuit 38 is connected with between a rectifier circuit 34 and the welding electrodes 10a and 10b via an induced voltage elimination circuit 36.
