Title: Power supply apparatus
Inventor: HAMAHATA SEIJI
IPC: H02M7/12
Filed: 1992-07-24
Abstract: PURPOSE:To provide a power supply apparatus which is small in size and low in cost and facilitates suppression of an output voltage fluctuation and a stable operation even if a power supply voltage declines. CONSTITUTION:A power supply apparatus has a switching device Q1 which converts a low frequency power into a high frequency power and a radio frequency transformer T1. The driving power supply of the switching device Q1 is composed of a constant voltage source V1 obtained from a commercial power supply and a variable voltage source V2 obtained from an oscillation output. V1<V2 is satisfied in an ordinary power supply voltage fluctuation range and the output fluctuation is compensated by the variation of V2. V1>V2 is satisfied when the power supply voltage is below a predetermined value and, when V1 is below a certain value, the oscillation is discontinued. With this constitution, a power supply apparatus by which a stable output with little output fluctuation can be realized at a low cost. Further, an unstable intermittent oscillation produced when the power supply voltage declines can be avoided.

Title: Information recording disk and its driving device
Inventor: OZAKI KAZUHISA
IPC: G11B19/02
Filed: 1993-07-16
Abstract: PURPOSE:To drive a disk with less torque and good balance and to improve the life of a slider by eliminating the need for specific positioning and decreasing the burden of a motor. CONSTITUTION:Ring electrodes 22 connected to a RAM 18 arranged in the unrecording region 14 of an information recording disk 10 are formed to a concentrical circle with the center of the disk and come into contact with spring electrodes 34 on a driving device side in a symmetrical position. These spring electrodes 34 are connected to sliding electrodes 38 formed along a revolving shaft 36. The slider at the front end of an arm part 44 comes into contact with these sliding electrodes 38 only when the RAM 18 is accessed by a plunger mechanism. The torque load of a spindle motor is thereby decreased and the consumption of the slider is reduced as well.

Title: Radio receiver
Inventor: MURATA KAZUO
IPC: H03L7/10
Filed: 1995-07-12
Abstract: PROBLEM TO BE SOLVED: To provide frequency control at a radio receiver without using any analog switch by performing step control to a voltage to be impressed to a voltage controlled oscillator(VCO). SOLUTION: Based on a reference oscillation frequency from a VCO 11, a received signal frequency is transformed 5 to an intermediate frequency. In the case of this transforming processing, a first comparative frequency based on the reference oscillation frequency is compared with a second comparative frequency based on the intermediate frequency by a comparator 14 and based on this compared result, a controller 28 successively performs the step control to the voltage to be impressed to the oscillator 11. Thus, the respective first and second comparative frequencies are made closer.  Therefore, when a received electric field is strong, the step control is performed in a certain direction so that the reference oscillation frequency can be low but when the received electric field is weak, the step control is performed in a certain direction so that the reference oscillation frequency can be high. Accordingly, the control can be processed by a software and averaged by any mathmatical method and the time for control is easily shortened and varied.

Title: Wafer holder
Inventor: TEI RIYUUWA
IPC: H01L21/673
Filed: 1996-07-29
Abstract: PROBLEM TO BE SOLVED: To obtain a wafer holder by which a uniform support force is applied to the whole outer circumferential part of a wafer and by which the yield of a semiconductor device is increased by a method wherein the shape of an inside edge is similar to the outer circumference of the wafer and a width which is sufficient to hold the whole edge of the wafer is formed as a width between an outside edge and the inside edge. SOLUTION: A plurality of leg parts 42 are formed at the outer circumferential edge of a wafer holder 40. The leg parts 42 are separated from each other by every prescribed angle. Then, a width between the outer circumferential edge and an inner circumferential edge has a width which is sufficient to hold the whole outer circumference of a wafer. Consequently, the wafer holder 40 supports the whole outer circumference of the wafer. As a result, it is possible to prevent a locally concentrated force from being applied to the wafer. In addition, the wafer holder 40 uses a continuous area to support the wafer. Consequently, a uniform force can be applied to the wafer.

Title: Measured value displaying device
Inventor: WATANABE KAZUMASA
IPC: G01D3/02
Filed: 1996-07-29
Abstract: PROBLEM TO BE SOLVED: To shorten the time required for making indication adjustment by constituting the device so that the device can control the reading of indicated data stored in a memory based on a control signal which is synchronized with the turn-on of power supply and another control signal which is outputted at the time of performing the indication adjustment. SOLUTION: The indicated characteristic data required for indicating various kinds of measured values are stored in advance in a memory 4. When an ignition switch is turned on, indicated characteristic data stored in the memory 4 are given to an indicated angle calculating section 12e through an indicated characteristic data reading section 12c. The calculating section 12e processes a false vehicle signal from an indication adjusting device 13 and moves the pointer of a meter 1 to the point corresponding to the false measured value. When the indicated result contains an error, the calculating section 12e writes the indicated characteristic data which do not contain any error in the memory 4 from the adjusting device.  Upon completing the writing, new indicated characteristic data are given to the calculating section 12e and a false signal is processed similarly to the preceding time, and then, the pointer is moved correspondingly. Thus the indication adjustment is repeated until the error disappears.

IPC: G11B5/245
Filed: 1989-07-31
Abstract: PURPOSE:To allow a high-density perpendicular magnetic recording with high speed responsiveness by forming the thin film of a heat sensitive magnetic material covering a thin-film permanent magnet and heating this film to the temp. near a Curie temp. or above. CONSTITUTION:The internal magnetic resistance as a permanent magnet increases extremely if the thin-film permanent magnet is magnetized in its longitudinal direction. Magnetic fluxes are shorted and the leakage of the magnetic fluxes decreases if this thin-film permanent magnet 3 is coated with the thin film 4 of the heat sensitive magnetic material having a high magnetic permeability at room temp. The magnetic fluxes from the thin-film permanent magnet 3 are no longer shorted if the thin film 4 of the heat sensitive magnetic material having the Curie temp. of the temp. slightly higher than room temp. is selected and is heated to the temp. near the Curie temp. or above. A magnetic pole, therefore, appears at the end of the thin-film permanent magnet 3 and the magnetic pole is eventually exposed. The thin-film permanent magnet 3 acts as a single magnetic pole magnetic head. The extremely thin single magnetic pole magnetic head of the high-speed response is obtd. in this way and the recording at a high density is possible.
