摘要： When an outer core that is to be mounted on a reactor is seen in plan, the outer core is a compact that has a plan-view shape in which a side of the outer core that is opposite to a facing side of the outer core, which faces the inner cores, has a smaller dimension in a width direction, which is parallel to a facing surface, than the facing side of the outer core. A method of manufacturing such an outer core includes a preparing step and a compacting step. In the preparing step, coated soft magnetic powder including multiple coated soft magnetic particles formed by coating soft magnetic particles with insulating coated films is prepared as raw-material powder of the outer core. In the compacting step, a compacting space 31, which is defined by a pillar-like lower punch 12 and a tubular die 10A, is filled with the coated soft magnetic powder and then the coated soft magnetic powder in the compacting space 31 is compacted by the lower punch 12 and a pillar-like upper punch 11, the lower punch 12 and the tubular die 10A being movable relative to each other. In the compacting step, the facing surface of the outer core is pressed by the upper punch 11.

摘要： A low-loss compact and a method for producing the compact are provided.A method for producing a compact by using coated soft magnetic powder that includes coated soft magnetic particles constituted by soft magnetic particles and insulating coatings coating outer peripheries of the soft magnetic particles includes a raw material preparation step and an irradiation step. In the raw material preparation step, a raw compact is prepared by press-forming coated soft magnetic powder. In the irradiation step, part of a surface of the raw compact is irradiated with a laser. Irradiating a part of a surface of a raw compact with laser increases the number of disrupted portions of conductive portions where constituent materials of the soft magnetic particles at the surface of the raw compact have become conductive to each other, and the loss of the compact can be decreased.

摘要： Provided are a green compact from which a low-loss core can be formed, a method of manufacturing the green compact, and a core for a reactor using the green compact. Parts of outer circumferential surfaces of green compacts 41 and 42 are molded with an inner peripheral surface of a through hole 10hA of a die 10A, and the other parts are molded with an outer circumferential surface of a core rod 13A that is inserted and disposed in the through hole 10hA. A raw-material powder P, which is a coated soft magnetic powder, is fed into compacting spaces 31 and 32 and pressurized by using a lower punch 12 (first punch) and an upper punch 11 (second punch). Then, the green compacts 41 and 42 are removed from the compacting spaces 31 and 32 by moving the die 10A with respect to the green compacts 41 and 42 without moving the core rod 13A with respect to the green compacts 41 and 42. An area that is on the outer circumferential surface of each of the green compacts 41 and 42 and that is molded with the core rod 13A does not rub against the core rod 13A, and thus a complete insulating layer is maintained in the area. Therefore, a core using the green compact 41 or 42 can reduce eddy current loss.

摘要： A gear pump rotor is provided including a combination of an inner rotor and an outer rotor whose numbers of teeth are different by one, and the discharge amount of the pump is increased by an increase of the tooth depth. At least one of an addendum curve and a dedendum curve of an inner rotor is formed by a locus of one point on formation circles that satisfy moving conditions that the formation circles move from moving start points to moving end points while changing the distances from an inner rotor center to the centers of the formation circles. The centers of the formation circles move by a distance in the radial direction of a base circle, and the formation circles rotate by an angle at a constant angular velocity in the same directions of the moving directions of the formation circles.
