Title: Control circuit for motor rotation
Inventor: YAHAGI YOSHIYUKI
IPC: H02P29/00
Filed: 1990-03-28
Abstract: PURPOSE:To shorten time until servolock of motor rotation phase and to diminish dispersion in time by controlling the gain of rotation phase control signals according to the error between rotation phase detection signal and phase reference signal. CONSTITUTION:An exclusive OR gate 22 that is a phase difference detection means detects the error (phase difference) between rotation phase detection signal SWP and phase reference signal RP. Resistors R2, R3 and an analog switch 25 that are variable gain means control the gain of rotation phase control signal according to detection output from the phase difference detection means 22. Hereupon phase difference detection and gain control in the phase difference detection means 22 and variable gain means R2, R3, 25 are attained when the rotation speed servo locks but the rotation phase servo does not lock. This process can shorten time until the servolock of motor rotation and further diminish dispersion in time until servolock of rotation phase.

Filed: 1981-05-27
Abstract: PURPOSE:To improve the efficiency of the transmission and reception for the picture information of plural originals having the same constant pattern, by dividing an original into the constant pattern and other picture areas and transmitting and receiving them independently. CONSTITUTION:An original slip A is read by a scanner 1 at the transmitting sideIand stored in an original slip storing circuit 2.

Addresses of the carrier car are set in an address setting section 13 and, if the unmanned carrier car is to be stopped, an address detecting signal is given to a decelerating instruction sending section 18 and stopping instruction sending section 20. Even after the decelerating instruction is sent, the optical signal of the carrier car 1 is given to the master station 5 and its peak value is successively updated by a peak value holding section 16, but, if the level of the photodetecting section 6r becomes lower than the peak value level held by the peak value holding section 16, the output of a comparator 15 is given to the stopping instruction sending section 20. In this case, the side lobe of the photodetecting angle alpha is not produced and the peak value signal from the light projecting section can be discriminated accurately, since the directional angle (B) of the photodetecting section 6r of the master station 5 is constituted smaller than the photodetecting angle (alpha).

Abstract: PURPOSE:To enable to shorten the accelerating time of a motor stably even if a load torque alters by calculating the detected current value and the detected speed value of the motor to calculate a load torque value, and increasing the reciprocal of the load torque value to the maximum value of the speed command. CONSTITUTION:The detected armature current value Ia and the detected rotating speed value NM of a DC motor 10 are inputted to a motor acceleration torque arithmetic unit 30, which thus divides the Ia by the NM and obtains a motor acceleration torque TM. Further, the differentiated values of the torque TM and the value NM are inputted to an arithmetic amplifier 26, which thus subtracts the torque TM and NM are inputted to an arithmetic amplifier 26, which thus subtracts the torque TM by the differentiated value of the detected value NM and calculates the load torque TL. This torque T1 is then inputted to a speed limit signal converter 27, which thus varies the limit value of the speed command to be inversely proportional to the TL.
