Title: Competition evading system between transfer cycle and pefresh cycle
Inventor: OKU NAOKO
IPC: G11C11/401
Filed: 1988-04-29
Abstract: PURPOSE:To provide three signals, a transfer refresh signal, a transfer signal and a refresh signal, with synchronous relation to evade competition to be generated at the time of transmitting image display data by allowing a transfer refresh control circuit to mask the transfer refresh signal and separate the masked signal into the transfer signal and the refresh signal. CONSTITUTION:The title system is provided with the transfer refresh control circuit 1 for outputting three signals, a transfer refresh signal, a transfer signal and a refresh signal, from a display signal and a clock signal, a priority control circuit 2 for outputting a most prior signal from a transfer refresh signal, a clock signal and an access signal and a transfer address counter 3 for outputting a transfer line address signal from a transfer signal. The circuit 1 masks the transfer refresh signal to form a transfer signal and a refresh signal. Consequently, synchronizing relation is held among these three signals and competition to be generated at the time of control based upon the transfer signal and the refresh signal can be evaded.

Title: Cellular electrofusion using electro alternation magnetic field
Inventor: UURURITSUHI JINMAAMAN
IPC: C12N5/14
Filed: 1990-04-24
Abstract: PURPOSE: To fuse cells of various dimensions approximately corresponding to an initial ratio of cells in a starting medium, by impressing an electrical alternating field and a direct current electrical potential pulse to the cells.  
     CONSTITUTION: An electrical alternating field in an ordinary magnetic field intensity useful for mutual attraction of cells in a liquid is impressed to the cells and the intensity of the magnetic field is gradually reduced to intensity equal to about a half or smaller than the initial intensity for about 5-30 seconds. The reduced intensity of the magnetic field is maintained for a fixed cell membrane contact time of about 5-60 seconds to bring the cells into contact with each other. The cell membranes of adjoining cells are bored by a direct current electrical potential pulse to carry out cell fusion. At least one impression of the direct current electrical potential pulse is carried out after the intensity of the magnetic field reaches the reduced intensity of the magnetic field.

Title: Production of fluorine-doped quartz glass
Inventor: TSUMANUMA KOUJI
IPC: C03B8/04
Filed: 1993-05-10
Abstract: PURPOSE:To provide a process for the production of a fluorine-doped quartz glass having high specific refractive index difference at stable deposition rate. CONSTITUTION:A fluorine-doped quartz glass is formed on the circumference of a starting member 10 by plasma outer deposition method. The deposition process is carried out by placing a plasma torch opposite to the starting member 10 and perpendicular to the length of the member and supplying a quartz glass raw material gas coaxially with a plasma flame 11 ejected from the plasma torch simultaneously with the supply of a fluorine-based gas 15 into the plasma flame 11 from a direction different from the direction of the quarts glass raw material. Since the fluorine-based gas is supplied to the plasma flame 11 independent of the supply of the quartz glass raw material gas, the etching of the formed glass with the fluorine-based gas can be inhibited to attain a stable deposition rate.

Title: Production of nonlinear high-polymer material
Inventor: NONAKA TAKESHI
IPC: G02F1/361
Filed: 1990-04-26
Abstract: PURPOSE:To prevent the denaturation of a nonlinear material by interposing an insulating layer between an electrode and a nonlinear optically active molecule at the time of orienting the nonlinear optically active molecule at the time of orienting the nonlinear optically active molecules in a host polymer by subjecting a matrix to an orientation treatment by an electric field using a counter electrode. CONSTITUTION:The insulating layer is interposed between the electrode and the nonlinear optically active molecule at the time of orienting the nonlinear optically active molecules in the host polymer by subjecting the matrix to the orientation treatment by the electric field using the counter electrode. The contact of the nonlinear material and the counter electrode is obviated by the intervening of the insulating layer in such a manner. The transfer and receipt of electrons between the nonlinear material and the counter electrode are, therefore, obviated and so-called current flow is eliminated. The denaturation of the nonlinear material is prevented and the intensity of SHG (second harmonic wave generation) is increased if the amt. of the nonlinear material to be added is an equal amt.

IPC: B21D1/05
Filed: 1988-05-02
Abstract: PURPOSE:To reduce the dispersion of the blank L camber by disposing work rolls alternately on the upper and lower sides and setting a crown having prescribed value on each work roll. CONSTITUTION:The prescribed value of crowns are set on the work rolls 2 of its own constituting a roller leveler 5 and the rollers are disposed alternately on the upper and lower sides.

Abstract: PURPOSE: To comply with multiple kinds with lower cost and to realize precision fabrication of them. CONSTITUTION: A lead frame mounted with semiconductor devices is fed to a press machine 21 out of press machines 21 to 23 for cutting work and each semiconductor device is cut off. The cutting work is performed step by step, feeding each semiconductor device by a transferring apparatus in a die to the press machines 22 and 23 in sequence. Therefore, the spacing between the press machines can be set wider and the press motor 85a to 85c, that are needed to be of higher output, can be mounted independently on each of the press machines 21 to 23. The spacing between the press dies is not required to be changed depending upon the change of the component pitch of the lead frame. Therefore, as the press motor is mounted on each of the press machines, the precision work of the components is possible.  As the press die spacing is not required to be changed, multiple kinds can be complied with lower cost.
