Inventor: SAWAZAKI YASUHARU
IPC: H04N5/92
Filed: 1986-06-13
Abstract: PURPOSE:To attain a stable video control operation, by eliminating the distortion of a video control signal receiving the distortion of a transmission line. CONSTITUTION:A television broadcasting wave selected by a tuner part 2 is detected as a video signal by a demodulator 3, but the video signal of 1Vp-p including the VPS signal is amplified to the signal of 2Vp-p at a video amplifier circuit 9, and is supplied to a low-pass filter 10. The signal passed through the low-pass filter 10, after passing a buffer 11, is changed to a control signal output 13 at a detector 5, and a form arranging circuit 7. At this time, the output 4a of the video amplifier circuit 9 is the signal receiving the distortion, but, an output 12 passing through the low-pass filter 10 is recovered to a signal from which a higher harmonic distortion is eliminated. Therefore, the control signal output 13 of the form arranging circuit 7 becomes a waveform devoted to an original VPS signal.

Filed: 1983-07-28
Abstract: PURPOSE:To prevent the infiltration of air into a pump with an reduction in the negative pressure working on a bubble catcher section by providing an accumulator between the pump for forcing a liquid and a bubble catcher provided upstream from the pump. CONSTITUTION:A pump 30 for forcing a liquid is provided, while a bubble catcher 10 upstream from the pump 30 and an accumulator 20 is placed between the pump 30 and a suction valve 31 of the bubble catcher 10.

Title: Electromagnetic flow meter
Inventor: WATANABE HIROSHI
IPC: G01F1/60
Filed: 1984-07-06
Abstract: PURPOSE:To perform the stable display of a flow amount by removing the effect of DC potential, by performing no measurement of a flow amount when the ratio of the change is sampling electromotive force, when no magnetic field is applied in the vicinity, is large at the sampling time of a flow amount signal. CONSTITUTION:A fluid flows through detector piping 6 toward the vertical direction in the drawing and a bipolar magnetic field is applied in a direction A. The electromotive force corresponding to the flow amount of the fluid generated between electrodes 8, 10 is taken in CPU38 as a digital value through an amplifying means 32, a sampling hold circuit 34 and an A/D converter 36. A switch 40 is closed at times ta-tb during a stop period when the magnetic field is zero and at times tb-tc during a period when positive and negative magnetic fields are applied and electromotive force is taken in. CPU38 displays the flow amount signal calculated from the values at the times tb-tc only when the change in the values at the times ta-td is small. By this method, the effect of DC potential is removed.

Title: Channel selection device
Inventor: WATANABE SHIGEHARU
IPC: H03J5/02
Filed: 1980-10-07
Abstract: PURPOSE:To prevent a temperature drift from occuring even in a range where a tuning voltage level is low, by providing a compensation voltage superposing circuit including an element, having temperature characteristics, between a tuning voltage generating circuit and the varactor diode of a tuning element. CONSTITUTION:A tuning voltage generating circuit 1 generates a tuning voltage VC', which is applied to a DC amplifier 3 through a buffer amplifier 2 and a resistance R1; and the output tuning voltage VC of the amplifier 3 is applied as a reverse bias to the varactor diode of a tuning circuit 4. A reference voltage Vr is applied to the positive-side input terminal of the amplifier 3 through a resistance R2 and diodes 5a and 5c. The voltage VC' varies between 0 and Vr, and the temperature coefficient of the forward voltage of the diodes 5a-5c is negative. A compensation voltage Vs generated from the voltage Vr through the diodes 5a-5c and the resistance R2 is superposed upon the voltage VC' and the voltage Vs rises as the level of the voltage VC' is low, so that when VC'=0, the circuit 4 tunes to the lowest reception frequency. Consequently, a temperature drift is prevented from occurring even in a range where the level of the voltage VC' is low.
