Patent JP-S62242415-A (JP)
Title: Optical switch
Inventor: AKIYAMA SHIGEO
IPC: H03K17/78
Filed: 1986-04-14
Abstract: PURPOSE:To transmit/interrupt an optical signal to/from an optical waveguide by switching the output voltage of an optical switch control circuit to a high/low level by a contactless relay using a photoelectric element and a power MOS. CONSTITUTION:If an optical signal is inputted when the output voltage of the optical switch control circuit A is in the high voltage state, optical electromotive force is generated from a photodiode D1 and impressed between the gate and source of an output MOSFET Q2. At that time, the gate potential of a depression type junction FET Q1 becomes lower than its source potential by a voltage generated in the 2nd photodiode D2. Consequently, the interval between the drain and source of the FET Q1 is turned to high impedance and the interval between the drain and source of the FET Q2 is turned to low impedance by the optical electromotive force of the photodiode array D2. Thereby, driving current is supplied to a light emitting element D3 by the output voltage of the circuit A and the element D3 outputs an optical signal.

Title: Device for giving sound image moving effect
Inventor: FUJIMORI JIYUNICHI
IPC: H04S7/00
Filed: 1984-04-28
Abstract: PURPOSE:To obtain sound image moving effects capable of enlarging the sound image moving to outside of a speaker with simple constitution by inverting and controlling the phase relation with respect to an input music signal for every half period of a modulation signal. CONSTITUTION:A phase inversion control circuit 41 gives an input music signal SG as one input signal of a selection circuit 43, and simultaneously gives said signal as the 2nd input signal to the circuit 43 after said circuit 41 inverts a phase in a phase inversion circuit 44. On the other hand, an output of a selection circuit 14 is received by a polarity discrimination circuit 45, and the circuit 43 is controlled in such a way that it can select an output of the circuit 44 with the aid of a polarity discrimination output S11 when said output is negative. Thus, when the polarity of the output of the circuit 14 is positive, the signal SG is inputted to a multiplier circuit 42 through the circuit 43, while the signal SG is given to the circuit 42 through the circuit 43 after said signal SG is phase- inverted in the circuit 44, when the output of the circuit 14 is negative. The multiplied result is transmitted to a selection circuit 20.

Title: Ignition device for engine
Inventor: YAMAMOTO MASAYUKI
IPC: F02P3/04
Filed: 1988-04-08
Abstract: PURPOSE:To prevent an air cleaner from becoming dirty by adding an engine stoppage detecting circuit for detecting engine stoppage in the ON condition of a main switch and a slow cut-off circuit for gradually turning off a switching element at the time of the engine stoppage. CONSTITUTION:In an ignition action, for example, if an engine is stopped after an ignition signal is inputted, since a transistor Tr 4 is left off in an engine stoppage detecting circuit 11, a time constant capacitor 15b is charged after the lapse of a certain time making a comparing input voltage higher than a reference input voltage, and the output of a comparator 13 becomes low (thereby judging the stoppage of the engine). Thereby, the transistor Tr 3 of a slow cut-off circuit 5 is turned off. Then, in the circuit 5, since a capacitor 6 is gradually charged gradually turning off a transistor Tr 2 to slowly cut off the current of a primary coil 1a, no high voltage is generated in a secondary coil 1b without causing irregular explosion and the blow back of exhaust gas into an intake system will not take place.
