Abstract: A soft magnetic material includes a composite magnetic particle and an organic substance. The composite magnetic particle has a metallic magnetic particle and a coating layer coating the metallic magnetic particle and containing an oxide therein. The organic substance is formed by adding at least one of a thermoplastic resin and a higher fatty acid having an effect of increasing resistivity of the material, to a non-thermoplastic resin having an effect of improving durability such as material fatigue limit. The organic substance is contained in the soft magnetic material by not less than 0.001% by mass and not more than 0.2% by mass. The present invention provides a soft magnetic material having high magnetic property and mechanical strength and also having fatigue property and resistivity satisfying durability enough for use as a motor core or the like, and a method for manufacturing the same. Further, the invention provides a motor core and a transformer core made of the soft magnetic material.

Abstract: A Stirling engine is provided with a piston and a displacer. When the piston is made to reciprocate inside a cylinder by a linear motor, the displacer reciprocates inside a cylinder with a predetermined phase difference relative to the piston. In parts of the displacer and the cylinder that receives the displacer, the parts facing a compression space are made of metal, and the parts facing an expansion space are made of a low-thermal-conductivity material. In the metal part, the fitting accuracy is defined.

Abstract: A yoke used for an electromagnetic actuator is formed by molding a soft magnetic iron powder, and, in the yoke, a discontinuous portion is formed which prevents the occurrence of eddy current loss. This discontinuous portion prevents eddy current and permits the actuator to operate at high efficiency.

Abstract: With spacers (30, 31) held between the central portion and the circumference of two plate springs (61, 61), a fixed shaft (67) erected on a fixed block (70) is inserted in a through hole (64) in the periphery of the plate spring (61) and also in the spacer (31), and nuts (68, 68) are applied for tightening from above and below (step #1). Thereby, a displacer supporting spring (6) is fixed to the fixed block (70). And the threaded portion (2b) of a rod (2a) is inserted in a through hole (63) in the center of the plate spring (61) and also in the spacer (30) from the upper surface side of the upper plate spring (61), and a nut (32) is attached to the threaded portion (2b) projecting from the lower surface of the lower plate spring (61) so as to fix the displacer (2) to the upper surface side of the upper plate spring (61) (step #2). In this state, small vibration is applied to the displacer supporting spring (6) (step #3).

Abstract: A soft magnetic material includes a plurality of composite magnetic particles each having a metal magnetic particle and an insulating film surrounding a surface of the metal magnetic particle, and an organic substance joining the plurality of composite magnetic particles together. The organic substance has a deflection temperature under load of not more than 100° C. With this structure, the soft magnetic material can obtain a desired magnetic property.

Abstract: A linear actuator has inner yokes, outer yokes forming gaps between themselves and the inner yokes, and a movable body provided with planar magnets in the gaps. Eight pieces each of the inner yokes and the outer yokes are arranged at equal angular intervals in a circumferential direction with planar faces of each of the inner yokes and the of the outer yokes being opposed to each other. The movable body has magnet retaining portions having a substantially triangular shape and placed between adjacent inner yokes and between adjacent outer yokes. A linear actuator having high magnetism usability can be structured using magnetic parts suitable for mass production.
