Patent JP-H03181920-A (JP)
Title: Photoelectronic integrated circuit
Inventor: MATSUDA KENICHI
IPC: G02F3/02
Filed: 1989-12-12
Abstract: PURPOSE:To eliminate a malfunction, to securely turn off an optical bistable switch, and to reduce the power of signal light which is necessary for erasing operation by providing a light absorbing layer whose band gap is smaller than a 1st base layer between the 1st base layer and a 2nd base layer. CONSTITUTION:The band gap of the 2nd base layer 17 is smaller than the band gap of the 1st base layer 13, but the light absorbing layer 15 whose band gap is equal to or less than that of the 1st base layer 13 is provided between the 1st and 2nd base layers. Therefore, when light 31 with wavelength lambdaOFF is made incident, a part of it is absorbed by the light absorbing layer 15 even if transmitted through the 1st base layer 13, so the light 31 with the wavelength lambdaOFF is not made incident on the 2nd base layer 17. Consequently, such malfunction that the optical bistable switch is turned on with erasure signal light is eliminated and the optical bistable switch can securely be turned off and the base layer of an OFF phototransistor is reducible; and the gain of the OFF phototransistor is increased and the power of the signal light required for the erasing operation is reduced.

Title: Noise reduction device
Inventor: UEDA NOBUO
IPC: G11B5/027
Filed: 1987-12-17
Abstract: PURPOSE:To sufficiently reduce noise and to obtain a reproducing video signal with a superior S/N by constituting a device in such a way that the time arrangement of reproducing output signals is performed by scanning the same track by two heads with different head width keeping a prescribed time of delay and those reproducing output signals are added. CONSTITUTION:The heads 2a and 2a1, and the heads 2b and 2b1 scan the same track keeping a delay time tau, and detect reproducing signals, respectively. Those reproducing signals are amplified by reproducing amplifiers 4a and 4a1, and a signal reproduced and amplified by the head 2a preceding in timing is delayed by the time tau. Since the reproducing signal of the head 2a preceded by the delay means 10 coincides with the reproducing signal of the succeeding head 2a1 in timing, the S/N of the output of an addition means 11 goes to 1/2. The reproducing signal 13 from which a crosstalk is eliminated passes reproducing signal processing systems 5 and 6, and the signal 9 synthesized at an adder 8 also becomes the reproducing video signal with superior S/N.

Filed: 1987-12-19
Abstract: PURPOSE:To eliminate a drive control circuit for a ferrite system, and in addition, to enable to drive the polarization plane switching devices of both systems by providing a pulse width modulating means of a pulse for controlling the polarization plane switching device of a servo motor system and a turning means into a DC. CONSTITUTION:The pulse width modulation circuit 12 to be triggered by the pulse from a differentiation circuit 11 outputs the pulse of a reference pulse width, and this pulse is summed with the pulse outputted from a voltage inversion circuit 13 by an addition circuit 14, and the positive and the negative pulses of the pulse width corresponding to the difference of the pulse widths of both pulses are outputted, and turned into a direct current by a filter 15. Then, a loop operates, and a DC voltage corresponding to the pulse width of the pulse to be impressed upon an input terminal 10 is obtained at an output terminal 17. Thus, since a pulse signal, that is, a control signal for the servo motor system can be converted into the DC voltage, that is, the control signal for the ferrite system, a special drive control circuit to generate the signal for the ferrite system comes unnecessary, and circuit constitution can be simplified.

Title: Video camera
Inventor: KOKUBU KOZO
IPC: G03B17/38
Filed: 1988-12-22
Abstract: PURPOSE:To prevent a video camera from being operated by the remote control against photographer's will by inhibiting the operation based on a remote control signal at the time of setting or electrically connecting a grip to a camera main body with respect to the video camera where the grip is freely attached to and detached from the camera main body. CONSTITUTION:When a signal in the low level is applied from a grip attachment/detachment discriminating part 16, a control part 14 of a video camera main body 10 discriminates that a grip 20 is not set yet or an operation button 26 is turned off. Then, the control part 14 receives an inputted remote control signal to start/stop photographing. Meanwhile, when a signal in the high level is applied from the grip attachment/detachment discriminating part 16, the control part 14 discriminates that the operation button 26 of the grip 20 is turned on, and the control part does not receive the remote control signal inputted through an infrared remote control light receiving part 15. That is, it is judged in this case that a photographer is taking a picture while holding the video camera, and only signals from switches on the video camera main body and the operation button 26 of the grip are received.
