Title: Magneto-optical recording device
Inventor: MURAKAMI YOSHITERU
IPC: G11B5/02
Filed: 1991-08-02
Abstract: PURPOSE:To make the width of a recording bit uniform and to improve a signal quality by controlling an optical beam corresponding to the inverting condition of an outside magnetic field. CONSTITUTION:A bit pattern detected from a recording signal by a pattern detection circuit 4 is sent to a laser power control circuit 6. In accordance with a bit inversion detecting signal, a driving current with an inverse polarity is impressed to a recording film via head 2 by a recording signal processing circuit 7. When the bit inversion detecting signal is received by a laser off circuit 5, a laser off signal is sent to the laser power control circuit 6 and the intensity of the optical beam is reduced so that the magnetization of the recording film is not affected by the outside magnetic field for the period necessary for inverting the outside magnetic field. Thus, based on the pattern detecting signal, the intensity of the optical beam is controlled by the control circuit 6 so that the width of the recording bit is kept constant and the intensity of the optical beam becomes a leading power at the time of reproduction while a signal is inputted from the laser off circuit. Thus, the width of the recording bit is made uniform.

Title: Phase shifting device having delay circuit
Inventor: CHIKUMA TOUICHI
IPC: G05F1/455
Filed: 1982-11-06
Abstract: PURPOSE:To obtain a phase shifting device which completes its working in a fixed time after the start with a simple constitution by applying the voltage obtained through the working of a thyristor to a delay circuit and applying gradually the output of the delay circuit to a part of a starting circuit. CONSTITUTION:When a sine wave AC voltage (e) is applied, the full-wave rectified voltage V is generated by a full-wave rectifier 1. A starting circuit 3 is actuated by a thyristor 2. The voltage drop of a resistance 9 due to a flowing full-wave rectified current charges gradually a capacitor 7 in a delay circuit 4 through a variable high resistance 8. Then a transistor 5 is also started. Thus the current of the circuit 3 is synthesized with the output current of the transistor 5, and a part of the synthesized voltage is applied to the gate of the thyristor 2. Therefore the anode current of the thyristor 2 is gradually deformed, and as a result the voltage (e) is stabilized in the form of a phase shift waveform after a fixed period of time. The width of said waveform can be optionally changed by the value of a resistance 8.

Abstract: PURPOSE: To realize reduction in leakage current, higher speed of operation and simplification of a circuit to improve properties of ME-HET, by making a base layer of a material such that an energy band gap expands from a collector layer toward an emitter layer. CONSTITUTION: A collector contact layer 2 made of n-InGaAs, a collector layer 3 of n-InGaAs and a base layer 4 of p-In1-x Gax As are formed on an InP substrate 1.
