Title: Noise prevention circuit
Inventor: OZAWA SATOSHI
IPC: H03K19/003
Filed: 1988-12-22
Abstract: PURPOSE:To prevent an interference by a noise by a method wherein, in an IC, a ground wiring part of a micro current circuit and a ground wiring part of other circuits are connected by a MOS transistor, an output signal of a shot-pulse generation circuit is connected to a gate of the transistor and a capacity is added to a part between the ground wiring part of the micro current circuit and a substrate. CONSTITUTION:A noise prevention circuit is constituted of the following: a noise- generation circuit 1; a previous-stage circuit 2 of the noise-generation circuit 1; a micro current circuit 3; other circuits 4; a shot-pulse generation circuit 5; a MOS transistor Qf; a capacity Cf. When the circuit 5 constituted in this manner receives an output of the circuit 2, it outputs a generated waveform to a gate of the transistor Qf and controls its ON/OFF operation. That is to say, when a gate input is at H, a GND wiring part of the circuit 3 and a GND wiring part of the other circuits 4 are connected; when it is at L, they are cut off. Accordingly, when a large electric current is output to the circuit 2 from the circuit 1, it is received by the circuit 5; the transistor Qf is turned off from the time when a noise is generated by the large electric current to the time when it is attenuated; a GND potential is maintained stably by the capacity Cf.

Title: Apparatus for monitoring roll surface
Inventor: KOYAMA KATSUHIKO
IPC: B21B31/08
Filed: 1997-11-28
Abstract: PROBLEM TO BE SOLVED: To remote-control an inline roll and obtain information of a defect position by projecting light of a projector from a direction of a specific angular difference to an inclined angle of an optical axis of a TV camera inclined by the specific angle to a normal of a surface of the roll. SOLUTION: TV cameras 2A-2E set in a rolling machine are inclined by 15-60 deg. to a normal of a face of a roll 1. Projectors 3A-3E project light from approximately the same direction which is within ±10% to an angle of the TV cameras. Each TV camera picks up an image of the roll 1 synchronously with a pulse of a pulse generator 4. TV camera controllers 51A-51E control to synchronize shutters, thereby coping with a contrast. Delay circuits 52A-52E adjust a timing, and a switch 53 sequentially switches images of the TV cameras and sends the images to an image-synthesizing circuit 54. A synchronous signal- synthesizing circuit 55 synthesizes the TV camera images for every frame.  Moreover, the synthesizing circuit synthesizes rotation position information of the synchronous signal roll, synchronous signals of the images and information of camera numbers, and records obtained image data. Information of a defect position can be obtained through monitoring from a remote pace.
