Title: Torque transducer
Inventor: MIYAKE KATSUYUKI
IPC: G01L3/10
Filed: 1990-06-30
Abstract: PURPOSE:To enable highly accurate detection and prevent an electromagnetic shield means and a fixed housing from being shielded electrically by holding a rotary shaft, equipped with a ferromagnetic magnetostrictive means which varies magnetic permeability according to torque, on a fixed housing member through a bearing means, and providing an electromagnetic shield means with a ground connection projection part for rotation prevention. CONSTITUTION:When the torque operates on the rotary shaft 10, annular belts 12 and 14 of the ferromagnetic magnetostrictive means vary in magnetic permeability and a magnetic field varies, so that the magnitude of the torque is detected. Ball bearings 30 and 32 are interposed between the shaft 10 and fixed housing member 26 to prevent relative deflection substantially. An electromagnetic shield case 44, on the other hand, is held on the member 26 fixedly in the axial direction and radial direction and a rotation stop projection part 86 connects the case 44 to an earth wire and also prevent the case 44 from rotating in the circumferential direction. This constitution enables the highly accurate torque detection and prevent the electromagnetic shield case and fixed housing member from being shielded electrically.

Abstract: PURPOSE:To facilitate the manufacture of a high-frequency transformer and to make possible a low cost reduction in the transformer by a method wherein at least one groove is provided in tabular conductor having a flexibility in the direction of the flow of a current flowing through the conductor. CONSTITUTION:A conductive material is a tabular (or striplike, foil-shaped or the like) conductive material 13 and round or triangular grooves 14 are formed in parallel to each other in both surfaces of the material 13 as means for sectioning into one conductor by one conductor. The grooves 14 are simply formed by pressing a tabular conductor plate using a roller with grooves or the like. In the case where the conductive material is used as a winding for magnetic component use, an insulator 15 is provided in such a way as to cover the whole surface of the conductor part 13. Thereby, eddy current is reduced, current due to a skin effect can be increased and the high-frequency characteristics of a high-frequency transformer can be improved. Moreover, the problem of insulation in a lap winding or the like at the time of winding of the conductive material can be also improved.
