Title: Power-supply apparatus
Inventor: ASAYAMA ATSUSHI
IPC: H02M3/28
Filed: 1999-07-27
Abstract: PROBLEM TO BE SOLVED: To reduce the capacitance of a smoothing capacitor, by a method wherein the detection of the power supply of a commercial power supply by a power-failure detection circuit is performed independently of the detection of a power-supply voltage value after a rectifying and smoothing operation by a voltage detection circuit, the reference value in the output circuit of a power-failure notice signal is controlled variably, and the output timing of the power-failure notice signal is changed. SOLUTION: This power-supply apparatus is provided with a power-failure detection circuit wherein a voltage, in a point B, which is obtained by rectifying and smoothing a commercial power supply Vin by using a diode bridge circuit DB1 and a smoothing capacitor C1 is detected so as to be compared with a reference voltage Vx by a comparator COMP1, and a power-failure detection signal ACDWN* is generated. In the power-supply apparatus, a circuit which is composed of a resistance 3 and a bidirectional photocoupler Q4 and which detects the AC voltage, in a point A, of the commercial power supply Vin is installed. When a power failure is detected, the reference voltage Vx of the comparator COMP1 is changed to a higher value. As a result, the capacitance of the smoothing capacitor C1 is reduced, and the production cost and the size of the powersupply apparatus can be reduced.

Title: Optical information recording/reproducing device
Inventor: UMEDA MASATOSHI
IPC: G11B7/126
Filed: 1981-12-26
Abstract: PURPOSE:To avoid the useless mission of light of a semiconductor laser and to ensure a long lifetime of the laser, by discontinuing the feed to the semiconductor laser in response to the recording end signal and starting the feed in response to the signal which moves a recording disk toward its radius direction. CONSTITUTION:In a reproducing mode, a disk motor 2 and a traverse motor 6 rotate with a command given from a system controlling circuit 3. Then an optical recorded information detector 4 irradiates a laser beam to a recording disk 1 through a semiconductor laser output controlling circuit 5 and then detects the reflected beam. The output of this detection is applied to a detected information processing circuit 7, and the recorded information is delivered. When the detector 4 detects the recording end signal out of the disk 1, the detected signal is applied to the circuit 3. Then the laser beam is stopped by the output signal of the circuit 3 and via the circuit 5. When the signal which shifts the detector 4 to the radius direction of the disk 1 is fed to the circuit 3, the irradiation of laser beam is started. As a result, a long lifetime is ensured for the semiconductor laser.

IPC: G11B5/39
Filed: 1994-08-12
Abstract: PURPOSE:To solve a problem of short circuits between an electrode and magnetic shield layers in a magnetoresistive effect head and to narrow the magnetic gap. CONSTITUTION:Nonconductive magnetic ferrite layers 7a, 8a are formed between insulating layers 3a, 3b and metal magnetic layers 7b, 8b for shielding so that magnetic shield layers 7, 8 have a two-layer composite structure of the nonconductive magnetic ferrite layers 7a, 8a and metal magnetic layers 7a, 8b. By this method, short circuits between an electrode 5 and metal magnetic shield layers (metal magnetic layers 7b, 8b) can be prevented and the effective magnetic gap can be rendered narrower since the nonconductive magnetic ferrite layers 7a, 8a act as a magnetic shield with metal magnetic layers 7b, 8b. Thus, the obtd. magnetoresistive effect head is suitable for high recording density.

Abstract: PURPOSE:To enable the titled device to attain the function of protecting an output transistor with a small occupation area by a method wherein an emitter region has the first and second electrodes, and a base region a base electrode: the first electrode is connected to the reference potential by connecting the second electrode to the base electrode. CONSTITUTION:An emitter resistor R3 is formed on a P type semiconductor substrate 1, and the base region 5 is formed by diffusing a P type impurity to an island-formed N type region 2 made electrically independent by insulation isolating regions 4; further, the emitter region 6 is formed by diffusing an N type impurity. One electrode of the emitter region 6 is connected to the base region 5 with a wiring metal 7, which metal is connected to the emitter of an output stage transistor Q2. The other electrode of the emitter region 6 is connected to a source terminal of overcurrent, and an N<-> region 2 is connected to the base of a transistor Q1. Since the transistor Q3 and the resistor R3 of the protection circuit can be thus formed with one element, it is unnecessary to provide the transistor Q3 and the resistor R3 separately, and the saving in chip size can be contrived.
