Title: Controller for induction motor
Inventor: TSUBOI TAKASHI
IPC: H02P23/16
Filed: 1982-02-22
Abstract: PURPOSE:To alleviate the variation in the torque of an induction motor due to the temperature rise of the induction motor by detecting the variation in the secondary resistance value from the variation in the voltage of the motor and correcting the slip frequency. CONSTITUTION:The voltage VM of an induction motor is detected by a detector 8. The voltage VM, current IM, slip frequency fS, and an inverter frequency fi are inputted to a correction rate arithmetic unit 9. The unit 9 calculates the correction rate of the slip frequency fS. This correction rate is inputted to a multiplier 10. The multiplier 10 corrects the slip frequency reference value fSO and produces the actual slip frequency fS.

Title: Picture display control circuit
Inventor: KUSAKABE MIZUO
IPC: G09G5/22
Filed: 1989-02-03
Abstract: PURPOSE:To change the picture on a screen with a scanning line as the unit by controlling the picture data output in relation to a vertical synchronous signal and the output of a comparator. CONSTITUTION:A first up-counter 12 outputs the counted value of a horizontal synchronous signal, and a second up-counter 15 and a down-counter 16 count up and down the numerical value of the horizontal synchronous signal in the boundary position between display and erase of the picture from the vertical synchronous signal respectively and output respective counted values. When the counted value of the first up-counter 12 coincides with that of the second up-counter 15 or the down-counter 16, a comparator 13 generates a prescribed output, and picture data is outputted by the vertical synchronous signal, and picture data is broken by the prescribed output of the comparator 13. Since this break vertical position is changed in every one picture, the picture is displayed to spread from the top to the bottom or is erased from the bottom to top. Thus, the picture on the screen is changed with a scanning line as the unit.
