Title: Controller for power supply stabilization and control method
Inventor: KIBI KAZUHITO
IPC: H02H3/48
Filed: 1995-09-26
Abstract: PROBLEM TO BE SOLVED: To ensure sufficient stability of system after removal of fault by performing the control at an accurate power generation control amount for a fault in any type of power system. SOLUTION: A power generation control amount corresponding to the kinetic energy of a generator at a predetermined time after removal of fault (control amount of generated power supply) is determined previously. When a fault occurs, kinetic energy is derived from generators 1A-1C upon elapse of predetermined time after removal of fault and a power generation amount corresponding to the kinetic energy is determined based on a predetermined power generation control amount. A minimum combination exceeding the (optimal control amount) is then selected based on the power generation control amount thus determined and trip signals are delivered to circuit breakers 4A-4C in order to limit (control) the power supply thus stabilizing the system.

Title: Method for shifting work roll in cold rolling
Inventor: FUJITA TAMIO
IPC: B21B1/22
Filed: 1993-10-05
Abstract: PURPOSE:To prevent the damage to the surface flaw of a rolling material by confirming the generation of the roll flaw in a rolling time and its position of a stand in the direction of the roll axis through a flaw detector, repeating the shifts of the work roll when this roll flaw is positioned in the plate way and removing the surface flaw. CONSTITUTION:The direction of the ground traces of the surface flaw of the roll is shifted from the rolling direction by shifting the work roll 1. The ground traces of the work roll 1 crush the projectives on the surface flaw through this shift, as a result, the roll flaw generated on the surface of the rolling material P can be gradated by this. The projectives of the ground traces on the work roll are crushed by the friction with the middle roll or the backup roll and this, too, acts on the reduction of the surface flaw. When the surface flaw occurs on the edge part of the rolling material P, the flaw part is pushed out by shifting the work roll to the external part of the plate way to prevent the damage. In this way, the roll flaw on the surface of rolling material can be pushed out to the external part of the roll width to prevent the damage.
