Title: Change-over system for electric current limit for side guide
Inventor: IMAGAWA KOUICHI
IPC: H02P7/292
Filed: 1979-10-11
Abstract: PURPOSE:To restrict the twisting torque in a small value, by simultaneously detecting the jump of the electric current of the motor and the drop of its speed, at pinching the material with the side guides, to limit the electric current. CONSTITUTION:At rolling the material with the caliber roll, the material is pinched by the side guides and is transferred so as to fit the material's position to the caliber's position according to the rolling schedule. When the motor driven side guides pinch the material, in order to prevent the excessive twisting torque generated in the shaft of the mechanical system and the motor shaft owing to the impact torque from the loading side and the driving torque of the motor, the pinch timing is caught depending on the electric current and the speed, and the electric current limit is changed over to the lower value. That is, the motor speed is reduced as the electric current jumps at pinching the material. At the point of simultaenous detecting the jump of the electric current and the drop of the speed, the electric current limit is reduced. Hereby, the twisting torque is restricted in a small value.

Abstract: PURPOSE:To bond ceramic without causing any damage to the ceramic to a metal substrate to be a heat sink by a method wherein the bonding between the heat sink material and the ceramic is accomplished by means of pressure welding. CONSTITUTION:Ceramic 12 is covered by a metal frame 13.
