Title: Controlling method for breadth in rolling process
Inventor: TSUJI YUUICHI
IPC: B21B37/00
Filed: 1980-10-01
Abstract: PURPOSE: To control the breadth of a material to be rolled to a prescribed value, by controlling the circumferential speed ratio of the rolling rolls.  
     CONSTITUTION: A controlling computer 1 computes the run-out side breadth deviation from information on the feed-in side breadth profile obtained by a breadth gauge 6, etc., installed on the feed-in side of a rolling mill, in consideration of the rolling condition, and then, computes the circumferential speed ratio the most suitable for absorbing the said breadth deviation from a stored model. The result of this computation is inputted to a speed controller 2 as a control reference; then, the breadth is controlled through a controlling action for the circumferential speed difference. The result of the breadth control is measured by a breadth gauge 7 installed on the run-out side of the rolling mill and is fed back to the controlling computer 1; hereby, the model stored in the computer 1 is suitably corrected correspondingly to temperatures, material quality, etc., of the material to be rolled.

Title: Automatic gauge controller for rolling mill
Inventor: TOMARU TAKAO
IPC: B21B37/18
Filed: 1978-11-08
Abstract: PURPOSE:To make the automatic gauge controller superior in the high accuracy, the stability, and the quick responsiveness, by employing the mathematic model of the outlet side gauge for estimating the outlet side gauge value without time lag. CONSTITUTION:The reference gauge data and the rolling load for giving this reference gauge are specified precisely by the pass schedule computer 12 in consideration of the characteristic of the sheet material, and are respectively taken as h2i and pi. Next, depending on the data of the rotational speed, etc., of the roll 7, the oil film correction value is calculated, and the zero point correction is made on the cylinder position. Thr reference value of the modulus of mill stiffness Mi of the screw down device is set, and the reference cylinder position data Si is calculated. If the aim value of the absolute value of the gauge is taken as h2i, the rolling load pi and the cylinder position Si corresponding to h2i are precisely calculated. Moreover, even if Mi is different from the actual value M of the actual screw down device, the deviation factor DELTAM/Mi is corrected. As a result, the quality of the rolled product sheet is improved.

Rings 29 and 30 are expanded, and opened by said expansion, and the ring 30 is pressed to the water discharged pipe 3 through the inner lining material 10. Heating is carried out in said state, and a bonding agent is cured. The process is completed by removing the hydraulic pressure, making the expansion component contracted and removing the same.

Title: Piezoelectric oscillator
Inventor: WAKITA MASAAKI
IPC: H03H9/17
Filed: 1996-05-07
Abstract: PROBLEM TO BE SOLVED: To accurately and rapidly detect and determine an organic solvent gas by immobilizing a hydrophobic chitosan to a piezoelectric oscillator. SOLUTION: To make a chitosan thin film formation characteristic, a normal chain alkyl group of carbon number not less than 8, desirably carbon number 8-22 of hydrophobic group of good orientation characteristic is introduced. The chitosan has primary amino group, and the amino group is dissociated in acid and dissolved in water. A hydrophobic reference is introduced by alkylating the amino group of the chitosan, so that hydrophobicity is given while hydrophilic is maintained. The hydrophobic chitosan is desired to be fixed to an piezoelectric oscillator as a double layer. The piezoelectric oscillator is pulled up after soaking in a water-dispersion-liquid, and the water is evaporated, so that the hydrophobic chitosan is immobilized.  Relating to the piezoelectric oscillator immobilized in this manner, gas concentration and frequency lowering amount keep linear relation even under the condition of coexistence of liquid phase, so that an organic solvent gas can be detected and determined in a large environment range.

Title: Power factor control system of overvoltage suppressing device of reactive power compensation type power converter
Inventor: SUGIYAMA SHIYUUICHI
IPC: H02J3/18
Filed: 1981-09-03
Abstract: PURPOSE:To perform secure control to a constant power factor by using the absolute value of a reactive power component calculated on the bais of the voltage and current of an AC power source system as the command value of the control, and using the reactive power component as a detection value. CONSTITUTION:A power detector 7' finds reactive power EIsinpsi and active power EIcospsi from the voltage and current of an AC power source respectively, and an absolute value arithmetic device 9 performs arithmetic to obtain a command value for a power factor regulator 8'. On the other hand, the EIsinpsi is used as a detection value. In this case, E is a voltage value, and I is a current value; and psi is a power factor angle, and 1/K is the gain of the arithmetic device 9. Then, the power factor is set nearly to 1 by decreasing the gain 1/K of the device 9 as much as possible, and when the gain is increased, the output of the device 9 reaches zero. The output is the command value of the regulator 8', so the reactive power component EIsinpsi is controlled to 0 and the power factor of the system becomes 1. For this purpose, said K is selected adequately to obtain an optional power factor.

Title: Multicolor electrophotographic recording device and color slurring correction device
Inventor: DAITO CHIAKI
IPC: G03G15/01
Filed: 1988-06-03
Abstract: PURPOSE:To record a long size image with a small-sized inexpensive device by conveying a continuous transfer medium back and forth, that means, feeding out the medium from a roll and rewinding it. CONSTITUTION:At the time of transferring,a transfer sheet 10 is conveyed in the direction of an arrow B at the same speed as a photosensitive drum 1 by conveying rollers 16 while it is fed out from the transfer sheet roll 13 and taken up to a winder 18. In order to prevent the occurrence of wrinkle of the transfer sheet 10 and the meandering or the oblique proceeding thereof, a braking force in a direction C opposite to the conveying direction is given to the transfer sheet 10 by a motor 14. Since the title device has such a constitution that the transfer medium is conveyed back and forth, that means, it is fed out from the roll and rewound, it is unnecessary to make a mechanism related to the conveyance of the transfer medium larger so as to record the long size image.

Title: Screen size adjustment device
Inventor: SHIRAI IZURU
IPC: H04N5/44
Filed: 1997-05-12
Abstract: PROBLEM TO BE SOLVED: To provide a screen size adjustment device on which a more powerful video image is displayed even when additional information is superimposed on an upper mask part in a laterally long image where the upper and the lower parts are masked. SOLUTION: An arithmetic circuit 5 divides a video image into three areas; left middle and right and detects a video image starting position at the respective areas. Based on a pattern of the detected video image starting position, whether or not additional information is superimposed on an upper masked part of the left or right area is discriminated. When superimposition of the additional information is discriminated, a video starting position of the area at which the superimposition of the additional information is discriminated is disregarded and the video starting position is determined based on a video starting position of the other area. An aspect ratio conversion circuit 6 applies aspect conversion to a video signal based on the video starting position obtained by the arithmetic circuit 5.

Title: Electrostatic coating method
Inventor: KADOWAKI TOSHIYUKI
IPC: B05D1/04
Filed: 1981-09-02
Abstract: PURPOSE:To eliminate the seasoning and hardening of paint at a knife edge part and uneven paint-application, by feeding a wide relatively slower-speed gas stream in from the rear periphery of a cup to be coated when the paint is diffused by the high-speed rotation of the cup. CONSTITUTION:Compressed air is supplied through the hollow part of a rotary driving shaft to an air-spraying ring 39 in close contact with the rear periphery of a cup 1 to be coated, and sprayed to the periphery of the cup 1 to be coated through many small holes formed at the front surface part of the air-spraying ring 39 along its circumference. The sprayed shaving air stream expands its width until it reaches a knife edge part 9 at the front end of the cup 1 to be coated, so that the speed of the stream becomes slow and that drying the paint at the knife edge part 9 is not accelerated. Since the gas stream itself is widened although its speed becomes slow, the diffusion of the paint does not spread so much.
