Title: Forced hydraulic differential gear device
Inventor: HAYASHI YUSHI
IPC: F16H48/26
Filed: 1990-07-20
Abstract: PURPOSE:To attain remarkable improvement in the straight line stability and directional steering performance of a vehicle by installing the shaft of a hydraulic motor on one side of the differential gear of a non-slip differential gear device and the external container of the hydraulic motor on the other side, thereby enabling the differential gear device to perform differential transmission at need. CONSTITUTION:The rotation inputted from a shaft 1 by rotational input or gear input is divided by gears 2, 3 into the rotor side and external container side of a revolving piston motor. A rotor 7 is rotated by feeding/discharging oil through pipelines 12, 13, but when the revolving piston motor is placed in the locked state without feeding this oil therein, the gears 2, 3 are also locked, and a vehicle is placed in the rectilinear travel state. In case a steering wheel is steered in this state, the vehicle makes a large turn with the slip of its front wheels. On the other hand, when the rotation on the driving side is stopped and the hydraulic motor is rotated, the all-wheel drive vehicle such as a four-wheel drive one is turned on the spot.

Filed: 1983-10-14
Abstract: PURPOSE:To inform visually the state that an emergency alarm broadcast is received and an emergency alarm broadcast reception function is on standby by allowing a light emitting diode to inform the state through its lighting and flickering operation. CONSTITUTION:While no emergency alarm broadcast is received, since an output of a decoder circuit 8 is at a low level, a transistor (TR)12 is nonconductive, its emitter is at a low level and one input to NAND gates 141, 142 goes to a low level, then an output of an oscillation circuit 14 goes to a high level and a TR16 is conductive. As a result, a light emitting diode 17 is lighted so as to inform the standby state. In receiving an emergency alarm broadcast, an output of the decoder circuit 8 goes to a high level through the discrimination of start and the TR12 is conductive. On input to the 141, 142 goes to high level, the oscillation circuit 14 starts oscillation and the light emitting diode 17 is flickered through the switching operation of the TR16. The flickering displays that the emergency alarm is under broadcasting.

Title: Video head circuit
Inventor: SHIMOI HIROSHI
IPC: G11B20/24
Filed: 1982-11-02
Abstract: PURPOSE:To shorten the distance from a video head to an amplifier circuit and to prevent the influence of noises by blowing a recording signal and a reproducing signal into a video head circuit without using a switching element. CONSTITUTION:At the recording, a recording signal impressed to an input terminal 4 is amplified and outputted by/from a recording amplifier circuit 1. The impedance of the video head 2 for the output recording signal is normally <=100OMEGA, but the input terminal of a reproducing amplifier circuit 3 is high impedance because the input terminal consists of an emitter, a follower, etc. Since the input terminal 4 is opened at the reproducing, the output current of the recording amplifier circuit is about ''0''. The bark current of the output of the recording amplifier circuit 1 is sufficiently low current of generally about 1mA, and if the impedance of the video head 2 is 100OMEGA, the current flowing into the video head 2 is several muV or less when considering voltage drop, and the current value can be ignored as compared to the several hundred muV, the voltage level of the reproducing signal. As compared to the input terminal of the reproducing amplifier circuit 3, the output terminal of the recording amplifier circuit 1 has sufficiently high impedance. Therefore, the reproducing signal detected by the video head 2 is impressed to the reproducing amplifier circuit 3.

Filed: 1991-08-02
Abstract: PURPOSE:To modulate the light absorbing intensity with different wavelength by 2 elements by constituting a non-symmetrical SEED element with 2 types of different pin diodes to be operated by different wavelength. CONSTITUTION:When the switch light of constant wavelength (lambda1) and constant intensity Pin1 is made incident on a diode element 31 at the wavelength area in which the light absorption is reduced by the increase of a reverse bias voltage, a low impedance condition is obtained, the reverse bias voltage is impressed to a diode element 32 and a high impedance is obtained. When the light of different wavelength lambda2 is made incident on the element 32 to be operated by the wavelength different from the element 31, and when trigger light intensity Pin2(lambda2) to be made incident on the element 32 is smaller than switch light intensity Pin1(lambda1), the reverse bias voltage impressed condition of 31 and 32 is not changed. At the time of Pin2>Pin1, the element 32 becomes the low impedance and the element 31 is changed to a high impedance condition (B). At this time, for the element 31, the light absorption becomes small and the light switching action of switch light intensity Pout1 is obtained.
