摘要： An actuator for controlling the movement of an element between two stable positions with pulsed electrical control without a change in polarity comprises: a ferromagnetic mobile mass, at least one electrically controlled wire coil that is fixed with respect to the mobile mass, at least two ferromagnetic poles that are fixed with respect to the mobile mass and on either side of the mobile mass. The actuator comprises at least one permanent magnet that attracts the mobile mass in order to achieve the two stable positions. The mobile mass defines, with the ferromagnetic poles, at least two variable air gaps during the movement of the mobile apparatus. The magnetic flux of the permanent magnet opposes the magnetic flux generated by the at least one coil regardless of the position of the mobile mass.

摘要： In the coil component, the coupling coefficient can be adjusted by the magnetic sheet and the insulator interposed between the pair of coils. For example, by increasing the magnetic permeability of the magnetic sheet so that the magnetic flux generated in the coil easily passes through the magnetic sheet, the coupling coefficient decreases. In the coil component, the coupling coefficient can be adjusted while the thickness of the element body is suppressed.

摘要： There is provided a method for producing metal foils, capable of easily crystalizing amorphous soft magnetic material of a plurality of metal foils into nano-crystal soft magnetic material by uniformly heating the metal foils. A laminate obtained by laminating the metal foils made of amorphous soft magnetic material is held by a holding member such that adjacent metal foils can be separated from each other in a laminated direction of the laminate. By conveying either the holding member or magnets in a direction perpendicular to the laminated direction as a conveying direction such that the holding member and the magnets come close to each other, the adjacent metal foils are separated from each other with a magnetic force of the magnets. The separated metal foils are heated to crystalize the amorphous soft magnetic material of the metal foils into nano-crystal soft magnetic material. The same magnetic pole of the magnets aligns in the laminated direction.
