Title: Magnetic recording and reproducing device
Inventor: HOSOKAWA NOBUO
IPC: H04N9/87
Filed: 1986-04-22
Abstract: PURPOSE:To attain excellent dubbing by detecting prescribed plural frequency levels of a reproduced FM signal and controlling the frequency characteristic via a variable equalizer in response to the level difference and using its output as a dubbing signal. CONSTITUTION:The level of a signal having a frequency fs being the FM modulation of a horizontal synchronizing signal and of a signal having a frequency fc being the modulation of a chrominance signal at a low frequency are detected by an fs level detection circuit 2 controlled by a control circuit 4 by using a reproduced FM signal such as a video signal and an fc level detection circuit 3 respectively. Then the variable equalizer 1 is controlled in response to the level difference of the signals having the frequencies fs, fc by a comparator 5 and the result is outputted as a dubbing signal. Thus, even when the kind of a tape and the operating condition such as temperature are changed, the compensation of the proper frequency characteristic is apllied and the dubbing with excellent picture quality is attained.

Title: External-magnetic-field compensating apparatus for magnetostriction type torque sensor
Inventor: ISHINO YASUSHIRO
IPC: G01L3/10
Filed: 1990-04-06
Abstract: PURPOSE:To eliminate the effect of leaking magnetic flux from an electromagnetic apparatus and to prevent the generation of the errors in the output of a sensor by providing a compensating coil around a power transmission shaft connecting the electromagnetic apparatus and a magneto-striction type torque sensor, and offsetting a magnetic field affecting on the torque sensor. CONSTITUTION:A compensating coil 12 is connected to an exciting coil 2 of a DC motor 1 in series. The coil 12 is concentrically wound around the outer surface of a power transmission shaft 4 for connecting the motor 1 and a magnetostriction type torque sensor 6. Therefore, a current which flows into the motor 1 flows through the coil 12. Compensating magnetic flux PHIC is generated in the shaft 4. The magnitude of the magnetic flux PHIC can be made equal to the magnitude of leaking magnetic flux PHIM by adjusting the number of the windings of the coil 12. Since the magnetic fluxes PHIM and PHIC are directed in the reverse directions, the magnetic fluxes act so as to offset to each other. Thus, the effect of the leaking magnetic flux on the torque sensor is removed, and the output errors of the torque sensor can be eliminated.

Title: Multioutput switching power unit
Inventor: YAMATO SHIGEKI
IPC: H02M3/28
Filed: 1986-04-24
Abstract: PURPOSE: To stabilize multiple outputs by controlling the feedback quantity of a circuit in accordance with the fluctuation of DC output voltage, which feeds back AC output voltage to a DC input power source driving a switching circuit through conversion of AC output voltage to DC one. CONSTITUTION: The voltage set up at the secondary output windings 63-66 of a transformer 6 of a switching circuit 2 is rectified, smoothed and supplied to load RL. A feedback quantity control circuit 8 monitors specific DC output voltage and detects the quantity of voltage variations. When the DC output voltage raises, the reactance of a reactor winding 822 of a reactor 82 increases. As a result, the voltage applied to an input winding 91 of a feedback transformer 90 in a feedback circuit 9 drops. On that account, the feedback voltage becomes low. Consequently, the driving DC voltage of the switching circuit 2 becomes low. So does the output voltage of a transformer 6 for oscillation and outputting.
