Title: Motor controller and control method
Inventor: OKUYAMA TOSHIAKI
IPC: H02P29/40
Filed: 1990-04-24
Abstract: PURPOSE:To suppress vibration by constituting a motor control system, from motor speed to motor generating torque, of a compensating transfer function comprising the sum of a negative feedback proportional compensation element and a positive feedback differentiation compensating element. CONSTITUTION:A torque signal TRS is provided from a speed control circuit 1 to a speed model 8 which then outputs a reference speed for a motor 24 corresponding to the torque. An encoder 27 provides a pulse proportional to the rotational speed to a speed detector 28 which then converts the pulse into an actual motor speed WM. In place of a value proportional to the difference between the reference speed and the actual speed WM of the motor 24, the actual speed WM is added to a compensation transfer function 9 comprising the sum of a negative feedback proportional compensation element and a positive feedback differentiation compensating element thus producing a value to be employed actually.

Abstract: PURPOSE:To lower contact resistance and besides increase layer withstand voltage, by forming a metallic silicide film, then performing ion implantation all over the surface, then performing a patterning process of the metallic eilicide film, and then covering it with an insulating film. CONSTITUTION:A first insulating film 2 is formed on a main surface of a P type single-crystal substrate 1. An interconnection layer 3 of a poly-crystal Si film is formed thereon. After a second insulating film 4 is then formed on the layer 3, a hole 4a for a through hole is formed in the film 4. A high-melting- point metallic silicide film 5 is then formed all over the surface, and ion implantation of high-dosage phosphor is also performed all over the surface. Thus, contact resistance can be prevented from becoming high. After patterning of the film 5, then a SiO2 film 8 is formed as a third insulating film. Thereafter, a PSG film 8 is formed and heat treatment is performed to reduce the step difference. Hence, contact resistance between the polycrystal Si film and the metallic silicide film can be lowered. Besides, formation of the film 8 after patterning of the film 5 enables layer withstand voltage to be increased.
