Title: Drive circuit of oscillatory wave motor
Inventor: SASAKI TOYOJI
IPC: H02N2/00
Filed: 1988-05-17
Abstract: PURPOSE:To enhance universality of a motor and to extend the reference phase in a wide range by making serrate waveforms, etc., through a reference phase circuit, then by comparing this waveform voltage with the decided voltage by a comparator, and by making a reference phase. CONSTITUTION:In a drive circuit of an oscillatory wave motor a voltage variable oscillator 1 generates a frequency square wave signal four times as high as the optimum driving frequency in which the number of revolutions is at its maximum and supplies it to a frequency dividing phase shifter 3. The signal is then divided into a quarter each to generate signals phi1-phi4 in 90 deg. phase difference. Through a power amplifier 3 it is added to the voltage of a motor 4 and drives the motor 4. The monitor voltage VFB at a monitor electrode 4-c of the motor 4 is given to a driving point detection circuit 6 through a rectification circuit 5. This detection circuit 6 compares the phase of output signals from a reference phase circuit 8 with the phase of output signals from the rectification circuit 5 and gives an output according to its result to a frequency control circuit 7. The output of the circuit 7 thereby controls the output frequency of the voltage variable oscillator 1.

Filed: 1982-07-13
Abstract: PURPOSE:To reduce color shift generated on a profile section and a phenomenon colored into moire state, by providing an inverse correcting circuit in a primary color signal system amplifier in a color image pickup device. CONSTITUTION:An output signal of the image pickup device applied to an input terminal 11 becomes two modulated primary color signals at an attenuator 14 and an adder 15. The output signal of the adder 15 is subtracted with a signal being a half amplitude of a carrier amplitude in picking up a low frequency pattern of white 100% level applied from an input terminal 16. This signal is demodulated at a synchronizing detection circuit 21 to correct inversely the characteristic boosted at high frequencies with the inverse correcting circuit 23 so as to avoid unnatural emphasis at a high frequency region. Since the output of the circuit 21 becomes a video signal keeping the symmetrical relation of positive and negative polarities around the level 0 by the operation of the subtractor 18, a true blue signal is obtained by superimposing the video signal a half the white 100% DC level from an input terminal 24 on the output of the circuit 23 at an adder 26.
