Title: Superconductor wiring board
Inventor: IRISAWA NAOSHI
IPC: H05K1/09
Filed: 1987-10-08
Abstract: PURPOSE:To prevent a change in quality of a superconductor by a method wherein a metal layer is installed between a ceramic substrate and the superconductor. CONSTITUTION:A metal layer is installed between a ceramic substrate and a superconductor. When an oxide-based superconductor is used, it must be baked in an oxidizing atmosphere at a temperature of 900 deg.C or higher; accordingly, a metal which is stable in the high-temperature oxidizing atmosphere, e.g. Ag or Au, is preferable because its acid-resistance is high and its conductivity is excellent. By this setup, the superconductor is bonded firmly to substrate; the superconductor is not disconnected; the superconductor does not into direct contact with the substrate; accordingly, it is possible to prevent a change in chemical quality of the superconductor.

Title: Auxiliary magnetic pole excitation type vertical magnetic head
Inventor: IMAMURA TATSUO
IPC: G11B5/127
Filed: 1985-11-11
Abstract: PURPOSE:To prevent an external magnetic field from entering an auxiliary magnetic pole body and inductance from increasing and to facilitate the manufacture of a vertical magnetic head by embedding and fixing the auxiliary magnetic pole body in the recessed part of a magnetic material block with high magnetic permeability. CONSTITUTION:A main magnetic pole 15 is embedded and fixed in the recessed part 16a of a shield block 16 with high magnetic permeability and an auxiliary magnetic pole body 22 is embedded and fixed in the recessed part 19a of an auxiliary magnetic pole block 19 made of the same magnetic material; and a main magnetic pole film 11 and the main body 22 are set opposite each other across a recording medium 4. Even when an external field 26 is applied during magnetic recording as shown by an arrow X2, it passes through the blocks 16 and 19 and exits to the air. Winding is embedded around and in the outer periphery of the main body 22, so its manufacture is facilitated and it is fixed to the block 19 with a nonmagnetic adhesive 28, so the external magnetic field does not enter the auxiliary magnetic pole. Therefore, the external magnetic field and recording magnetic field 25 are separated to prevent the recording and reproduction level from lowering and the inductance of the auxiliary magnetic pole from increasing.

Filed: 1996-09-25
Abstract: PROBLEM TO BE SOLVED: To provide a power supply apparatus which controls irregular rises of a DC voltage under a light load condition, also controls a rush current and may be formed with fewer number of elements than that of the existing apparatus. SOLUTION: An AC power supply AC is rectified by a rectifying circuit DB. A capacitor C0 is selectively connected for rectifying an output of the rectifying circuit DB and power supply of an inverter circuit 2 via a switching element SW0 . The inverter circuit 2 uses a switching element Q2 in common, as an input distortion improving circuit 1, which is also operating as a voltage rise chopper circuit. After the predetermined time has passed from turning on of the power supply, the switching element SW0 is controlled, to connect a capacitor C0 to a resistor R1 and the capacitor C0 is connected to the switching elements Q1 , Q2 when a load is normal. Thereby, a rush current generated immediately after turning on of the power supply can be prevented, and there is no rise of voltage across the capacitor C0 during a light load.  Since the capacitor C0 is used in common for a couple of functions with the switching element SW0 , number of parts may be reduced.
