Title: Voltage type inverter device
Inventor: NAGANO ISAMU
IPC: H02P23/20
Filed: 1981-04-09
Abstract: PURPOSE:To achieve a sudden acceleration and deceleration by a method wherein the ratio is kept constant of the motor voltage against the motor frequency. CONSTITUTION:The output of a voltage controlled amplifier 10 is of the negative polarity when on power running and of the positive polarity under braking, and the polarity is discriminated by a torque direction detecting circuit 21. Power running causes the torque direction detecting circuit 21 to yield a signal to place the braking current controlled amplifier 15 in a stop status, which in turn causes a braking phase controlled circuit 16 to output a signal to turn off a switching device 19. Application of brake causes the torque direction detecting circuit 21 to output a signal placing the braking current controlled amplifier 15 and the braking phase controlled circuit 16 in an operating status. Regenerative run causes the output of the voltage controlled amplofier 10 to be compared with the braking current coming through the braking current detecting detector 18 and then inputted to the braking current controlled amplifier 15. The output of the braking current controlled amplifier 15 is inputted to the braking phase controlled amplifier 16 yielding a signal in response to which the switching device 19 is chopped.

Title: Coding of color television signal and decorder and its method
Inventor: BURODERU UENTORANTO
IPC: H04N9/64
Filed: 1989-03-06
Abstract: PURPOSE: To send a color television signal taking the physiological aspect of human eyes into account by selecting a frequency band of a primary vertical filter that receives a 1st color difference signal to be narrower than that of a primary vertical filter that receives a 2nd color difference signal. CONSTITUTION: The pass band of a primary vertical filter 32 for receiving a horizontally band limited color difference signal U is selected to be narrower than that of a primary vertical filter 42 for receiving a horizontally band limited color difference signal V. The reason why this means is adopted is that human eyes are not so much sharper substantially with respect to the instability of action relating to the color difference signal U than the instability of action relating to the color difference signal V. Accordingly, the color difference signal V is transmitted with higher resolution (or at a high frequency band) in a primary direction than that of the color difference signal U. Thus, a color television signal paying more attention to the physiological aspect of human eyes can be transmitted.
