Title: Disk chucking device
Inventor: YAMASHITA NORIO
IPC: G11B17/028
Filed: 1998-06-23
Abstract: PROBLEM TO BE SOLVED: To prevent the axis misalignment between a turntable and a disk clamper at the time of a disk chucking by providing a conical recessed part at the center axis of either a disk guide or a disk clamper and also providing a projected part having a sphericality to be engaged with the recessed part at the center axis of another part. SOLUTION: When a misaligment is generated between the center axis of a turntable 3 and the center axis of a disk clamper 5 at the time of the disk chucking, the sphericality 12 of a projected part 11 hits on the upper part of the conical recessed part 3c of a turntable 3 and an arm part 14 increases a repulsive elastic force and the part operates so as to move the disk clamper 5 until the center axis of the projected part 11 reaches a position where the conical recessed part 3c is most recessed.  Moreover, even in a constitution in which a transparent hole is formed coaxially with the center axis of the disk clamper 5 and a pin-shaped member is putted into the transparent hole and a sphericality is formed at the top end of the member and one end of the member is attached to the clamper 5 with a spring pushing the rear end part of the member, the pin-shaped member similarly operates so as to move the clamper 5.

Title: Method for lining metal tube
Inventor: HONDA NAOJIRO
IPC: B29L23/00
Filed: 1987-07-17
Abstract: PURPOSE:To facilitate the control of lining operation by a method wherein the lining operation is done by passing high temperature fluid through the inside of a lining tube, which is produced by adding power of metal hydrogenated material and inserted in a metal tube. CONSTITUTION:A lining tube 1, the outer diameter of which is formed slightly smaller than the inner diameter of a metal tube 2 to be inserted and made of mixture of synthetic resin abundant in heat resistance and elasticity and powdered metal hydrogenated material mixed with each other at the predetermined mixing ratio. And, the lining tube 1 is inserted in a metal pipe 2 and, after that, heating medium having a temperature, at which the metal hydrogenated material releases hydrogen, is flowed in the interior of the lining tube. As a result, the base material of the lining tube 1 expands thermally and, at the same time, the powdered metal hydrogenated material mixed in the lining tube 1 releases hydrogen and simultaneously expands itself. As a result,the diameter of the lining tube 1 increases, resulting in bringing the outer peripheral surface of the lining tube 1 into close contact with the inner wall surface of the metal tube 2. Thus, the control of lining operation can be done very easily.

Title: Inverter with output regulation mechanism
Inventor: KIJIMA SEIICHI
IPC: H02M7/538
Filed: 1996-06-19
Abstract: PROBLEM TO BE SOLVED: To reduce production cost by constituting the output regulation mechanism for an inverter of a potentiometer by a control means producing a control signal each time the output signal from the potentiometer exceeds a predetermined level and a switching member thereby simplifying the output regulation mechanism. SOLUTION: Since the input voltage Vo to a step-up transformer 11 has a repetitive waveform (sinusoidal full-wave rectified voltage), varying periodically for each oscillating operation, a potentiometer 3 produces an output signal VS1 having waveform dependent on the input voltage Vo and operation set values upon application of the input voltage Vo. Every time the output signal VS1 from the potentiometer 30 is repeated, a control means outputs a control signal VS2 during an interval in which the output signal VS1 exceeds a predetermined level. A transistor 32, provided in the input current path of the step-up transformer 11, is subjected to conduction/nonconduction control by the control signal VS2. This constitution realizes an inverter providing a main regulation mechanism, having simple circuitry and suitable for reducing the production cost.
