Title: Inner-rotor motor
Inventor: FUKITA TAKU
IPC: H02K1/20
Filed: 1994-07-28
Abstract: PURPOSE:To make the surface area of an outside surface large and to enhance the dissipation of heat generated by a coil or the like at the inside of a laminate by a method wherein an uneven shape is formed on the outside surface of the laminate arranged at the outside of a rotor for an inner-rotor motor. CONSTITUTION:An inner driving motor 2 is constituted in such a way that a rotor 3 fitted with a driving magnet supports its rotor shaft 9 by a bearing 10 and that it is supported so as to be rotatable with reference to the side of a stator. In addition, a rotating polygon mirror 4 is attached to the upper part of the rotor 3 by a plate spring 11. Individual sheets whose outside diameter is different are sandwiched alternately or several sheets whose outside diameter is large are sandwiched between laminates 8 arranged at the outside of the rotor 3, and uneven parts are formed on the outside surface of the laminates 8 so as to increase a surface area. Thereby, when the motor is driven, heat generated by a coil or the like at the inside of the motor can be dissipated with good efficiency.

Title: Laminated film of insulator thin film and oxide superconducting thin film and its manufacture
Inventor: TANAKA SATOSHI
IPC: H01B13/00
Filed: 1993-07-14
Abstract: PURPOSE:To restrain the mutual diffusion at the interface between an oxide superconducting thin film and an insulator thin film by a method wherein a monolayer of a noble metal is arranged between the oxide superconducting thin film and the insulator thin film. CONSTITUTION:An insulator thin film is laminated on an oxide superconducting thin film which has been formed in advance on a substrate. In this case, after the oxide superconducting thin film has been formed, a noble metal layer in the thickness (monolayer) of the portion of a monoatomic layer is formed continuously on the oxide superconducting thin film inside the same film formation apparatus, and, in addition, the insulator thin film is formed continuously on the noble metal layer inside the same film formation apparatus. Thereby, the monolayer by a noble metal prevents the mutual diffusion between the oxide superconducting thin film anti the insulator thin film. Consequently, since impurities are not diffused into the oxide superconducting thin film, its superconductive characteristic is excellent. In addition, the insulator thin film is excellent in an insulating characteristic because its composition is maintained.
