Title: Control method of continuous rolling mill
Inventor: MOROOKA YASUO
IPC: B21B37/00
Filed: 1980-04-25
Abstract: PURPOSE: To minimize the dispersion of plate thickness and tension variations, by measuring the state of plate thickness and tension, and accordingly controlling the roll opening degree and roll rotating speed.  
     CONSTITUTION: The desired thickness and tension are input from a host computer 150 into a schedule computer 140, and the calculated effect coefficient forward slip is output to a delivered strip thickness deviation calculating device 120 and a tension calculating unit 130. As rolling is started, the tension calculating unit 130 inputs rolling forces 61W6n and motor currents 71W7n, and calculates the opening tension of each stand to output to the thickness deviation calculating device 120. The calculating device 120 inputs speed 51W5n and thicknesses 41, 42 and calculates the exit side thickness deviation to output it to a memory unit 110 and an optimal control unit 100. The memory 110 inputs the outputs of 51W5n, and transfers the thickness at every specified small division. The unit 100 outputs the optimum operation amount to a speed controller 80 and a pressure down controller 90. The device 80, using the input speed control command signal and rolling pressure, armature current of the motor and motor speed, controls and motors 21W2n of each stand to the instructed speed.

Title: Selective etching of amorphous silicon
Inventor: ICHIKAWA YOSHIHARU
IPC: H01L21/308
Filed: 1989-03-06
Abstract: PURPOSE:To manufacture a thin film transistor in high throughput by a method wherein amorphous Si is selectively etched away using an organic alkali solution mainly comprising the fourth grade hydroxide ammonium or the quaternary ammonium salt. CONSTITUTION:Parts of amorphous Si film 3 and P-doped amorphous Si films 4 are etched away by hydroxide tetramethyl ammonium e.g. 1weight% of water solution at 50 deg.C using a gate electrode 7 and a gate insulating film 6 as masks. An amorphous Si thin film transistor thus manufactured is subjected to neither defective interlayer insulation nor dry areas on a glass substrate 1. Such a merit may be attributed to the application of the hydroxide tetramethyl ammonium water solution to the etching process of the amorphous Si. Furthermore, even if, during the other manufacturing process, the P-doped amorphous Si film 4 is etched away using an organic alkali solution mainly comprising the quaternary ammonium salt as well as a drain electrode 2 and a transparent source electrode 3 as masks, the said amorphous Si thin film transistor is subjected to neither defective interlayer insulation nor dry areas on the surface at all.

Title: Method and device for determining leakage impedance in alternating current power supply system
Inventor: ARUNOO AIHIMAN
IPC: G01R27/18
Filed: 1982-03-31
Abstract: A process and an apparatus for the determination of the total leakage impedance and the maximum conductor contact current of an ungrounded AC power supply system resulting from the total leakage impedance. An AC measurement current having a frequency that differs slightly from power frequency by a ratio other than a whole number is fed into the AC power supply system, which measurement current flows through the system leakage impedances to produce between supply system and ground, an interference pattern having the AC measurement voltage superimposed on the system voltage component at an interference pattern frequency (difference or beat frequency) of the pattern envelopes which is small with respect to the system frequency. By extracting and processing of the components of the interference pattern, it is possible to determine the AC measurement voltage component contained in the interference pattern. This allows a very precise determination of the total leakage impedance corresponding to the system frequency, and also of the maximum conductor contact current corresponding the total leakage impedance.

Title: Ball joint
IPC: F16C11/06
Filed: 1992-03-13
Abstract: PURPOSE:To prevent a ball joint manufactured by a calking process from the plastic deformation of the ball produced in the calking process and the quick wear after the calking. CONSTITUTION:The inside tip 10b of the opening of a tubular part to be calked is formed to diverge toward the opening before the calking, so that the inside tip 10b makes surface makes contact with a ball 8a in the calking. Thus, the ball is prevented from deformation by the surface contact of the inside tip with the ball during the caulking process. Since the surface pressure distribution on the contact part of the ball with the calked tubular part is uniform, even after the calking, quick wear can be prevented.

Title: Lc inversion circuit and high voltage pulse circuit
Inventor: IZEKI YASUSHI
IPC: H03K17/51
Filed: 1996-03-12
Abstract: PROBLEM TO BE SOLVED: To prevent the degradation of performance as much as possible and to prolong a service life by connecting a serial circuit for which the divided part of a magnetic switch and a switch element are serialy connected parallelly to a switch protection circuit. SOLUTION: Power changed through a laser head 5 by a capacitor 11 for charging is passed through a route composed of the capacitor 11 for charging again, the magnetic switch 16 and a switch 17, a current is made to flow and the voltage of the capacitor 11 is inverted. After the lapse of fixed time, the divided part of the switch 16 is turned to a conductive state to an inverse current and the current is started to flow to the switch protection circuit 18. At this time, the same voltage as the switch protection circuit 18 is applied to both ends of the serial circuit composed of the switch 17 and the divided part 16b of the magnetic switch 16. However, since almost all of the voltage applied to the circuit 18 is applied to the divided part 16b of the switch 16 in this LC inversion circuit 1, an inverse voltage applied to the switch 17 is reduced.  As a result, the characteristics of the switch 17 are stabilized and the service life is prolonged.

Title: Electrophotographic sensitive body
Inventor: OTA KATSUICHI
IPC: G03G5/047
Filed: 1987-03-09
Abstract: PURPOSE:To enhance sensitivity and to lessen the degradation in electric chargeability arising from pre-exposing fatigue by incorporating carboxylic acid amide into a layer in which an electric charge generating material is dispersed. CONSTITUTION:An electric charge generating layer 1 and charge transfer layer 2 are successively laminated on a conductive base 3. The carboxylic acid amide is incorporated into the layer 1 in which the charge generating layer is dispersed. Namely, the carboxylic acid amide adsorbs chemically on the charge generating material and provides the recombination center of the charges generated by light absorption and, therefore, the charges generated by the pre- exposing fatigue are quickly recombined and are thereby annihilated, conceivably, by which the drop of the charge potential of the photosensitive body is suppressed. The electrophotographic sensitive body which has the high sensitivity, extremely lessens the degradation in the electric chargeability arising from the pre-exposing fatigue and obviates the drop of the charge potential even after repetition of electric charge and exposing is thereby obtd.

Filed: 1994-03-25
Abstract: PURPOSE:To obtain optimum cleaning ability even when printing speed is changed by attaching a speed changer which changes the revolving speed of a fur brush in accordance with the charge of the printing speed to a motor. CONSTITUTION:Though the revolving speed of the fur brush 2 is kept constant even when the printing speed is changed in the conventional constitution, the speed changer 3 is attached to the motor 6 rotating the brush 2 in this device.
