Title: Method for controlling threading position of steel strip
Inventor: YOSHINAGA HIROHIKO
IPC: B23K11/04
Filed: 1999-04-14
Abstract: PROBLEM TO BE SOLVED: To stably control the passing position of a steel strip and to prevent the steel strip from being deformed. SOLUTION: A CPC device 19 is arranged on a route for continuously threading a strip to control the centering of the passing position. A pivot 32 is arranged on one end of a roll shaft 31 of a CPC roll 30, another end is deformed by a CPC cylinder 33 to change the inclination of the shaft 31 and change the threading position of the strip. The centering position is calculated from the position detection values of both the ends of the strip detected by respective detectors 34, 35. When a deviation is larger than a reference value, an operation command value to be applied to the cylinder 33 is divided by a fixed period and steps are controlled so as to gradually execute centering. Consequently a sudden change in the position can be evaded, thus stable control can be attained and the deformation of the strip can be prevented.

IPC: F02P3/04
Filed: 1981-07-10
Abstract: PURPOSE:To enable to prevent occurrence of accidents due to short-circuiting of a diode in an igniting apparatus utilizing a semiconductor rectifying circuit, by detecting a trouble of a diode through detection of the change in the direction of current flow, and disconnecting an operating circuit when the change in the direction of current flow is detected. CONSTITUTION:In case that an operating circuit is constituted by a diode D1, ignition plugs P1, P2 and a diode D4, current is passed from D4 P4 P1 D1. When the polarity of the voltage produced by an ignition coil 2 is reversed, current is passed from D2 P2 P3 D3. Here, if a diode D2 causes a trouble of short-circuiting, current is passed reversely through the circuit of the diode D2 and the ignition plug P2 when diodes D1, D4 and ignition plugs P1, P4 are in operation. This reverse current induces a negative voltage in a detecting coil S2 and a control circuit 10 detects occurrence of a trouble from the negative voltage. Then, the control circuit 10 operates to prevent occurrence of an accident by opening an emergency cut-off switch W2 and thereby stopping operation of the ignition plugs P2, P3. Here, since only the ignition plugs P1, P2 are operated in this state, rapid stopping of an automobile is not caused.
