Title: Rotation stopping method of motor
Inventor: FURUE RYOSUKE
IPC: G03B42/02
Filed: 1984-11-07
Abstract: PURPOSE:To shorten a time from the indication of a rotation stop to the rotation stop by applying a reverse maximum speed signal together with a rotation stop indication signal to a motor rotating at a designated speed, detecting a reverse rotation and then instructing a speed zero signal. CONSTITUTION:When a start operation is instructed by a switch 38, a selector 34 selects the output of a speed indicating voltage calculator 32, a power amplifier 42 amplifies it, and a motor 12 is rotated at a speed set by a speed setter 30. A rotary encoder 16 detects the rotating speed, a calculator 26 calculates the speed through a counter 22, and inputs to a comparator 28. The comparator 28 compares the actual speed with a set speed 30 to correct a deviation of the speed by the calculator 32. When a stop indicating switch 40 is closed to indicate a stop, the selector 34 selects the output of the reverse maximum speed indicator 36 to drive the motor 12 in reverse direction. When the encoder 15 detects the reverse rotation, the selector 34 selects a speed zero signal. Thus, a time from the stop indication to the stop can be shortened.

Title: Maximum power control method for solar battery
Inventor: KOSHIN HIROAKI
IPC: H01L31/04
Filed: 1999-08-20
Abstract: PROBLEM TO BE SOLVED: To stably control the output of a solar battery at a high speed by changing the gain of amplifying the deviation of a current command value supplied to a power inverter and an output current outputted from the power inverter corresponding to the variation range of an output voltage from the solar battery. SOLUTION: In a current control circuit 25, first control Loop-A for controlling the current command value so as to correct the deviation of a set reference operating voltage and the actual output voltage of the solar battery 10 and second control Loop-B for correcting the deviation of a specified current command value and the output current from an inverter 11 detected by a current detector 26 are activated. In this case, in the current control circuit 25, corresponding to the variation range of an amplitude generated at the time of changing the reference operating voltage, the gain of an amplifier circuit is changed.  That is, by increasing the gain in the case that the variation range is small, control is performed so as to make the output voltage of the solar battery 10 quickly reach a specified reference operating voltage, and the gain is reduced in the case that the variation range is large.
