Title: Stage mechanism controller
Inventor: TAKAHASHI MASAKO
IPC: H02P29/00
Filed: 1989-04-28
Abstract: PURPOSE:To make direction stable and to improve an effect by providing a stage mechanism controller, which controls the moving speed of a stage mechanism based on a speed command value and a speed feedback signal, and a learning means equipped with specified function. CONSTITUTION:A learning circuit 4 is equipped with learning function and reproducing operation function. At the time of a rehearsal, for the operating state of a suspending mechanism and a floor mechanism, etc., which are the stage mechanisms, the learning function detects the change of acceleration from the starting position of the operating state to the stopping position of the state and converts a speed feedback signal S2 at that time to distance data with the position of a change point as a reference. Then, these distance data are made correspondent to a speed command value S1 at that time and successively stored to a function generator by this learning function. At the time of reproducing operation, the position of initial operation is matched to the starting position at the time of the rehearsal and the reproducing operation function calculates a speed command value S4 at that time from the stored value and applies this calculated value to a stage mechanism controller 3 instead of the speed signal value S1 from a speed setter 1.

For example, cyclopentadiene epoxy resin or cyclopentadiene cyanate ester resin is used. When a glass transition temperature of the laminate is set to 150 deg.C or higher, warpage of the laminate can be reduced.
