20100193726 | SOFT MAGNETIC MATERIAL, DUST CORE, METHOD FOR PRODUCING SOFT MAGNETIC MATERIAL, AND METHOD FOR PRODUCING DUST CORE - A soft magnetic material includes a plurality of composite magnetic particles ( | 08-05-2010 |
20110068506 | METHOD FOR PRODUCING SOFT MAGNETIC MATERIAL AND METHOD FOR PRODUCING DUST CORE - The invention offers a method for producing a soft magnetic material. The method effectively produces a soft magnetic material having soft magnetic metallic particles each coated with a plurality of insulating layers. A soft magnetic material to be used as the material for a dust core is produced through the following steps: a step of preparing a material powder having composite magnetic particles produced by forming an insulating film containing hydrated water on each of the surfaces of soft magnetic metallic particles, a step of preparing a resin material containing silicone that cures through a hydrolysis-polycondensation reaction, and a step of mixing the material powder and the resin material in a heated atmosphere at 80° C. to 150° C. to form a silicone film on the surface of the insulating film. | 03-24-2011 |
20130038420 | GREEN COMPACT, METHOD OF MANUFACTURING THE SAME, AND CORE FOR REACTOR - 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 | 02-14-2013 |
20130127574 | OUTER CORE MANUFACTURING METHOD, OUTER CORE, AND REACTOR - 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 | 05-23-2013 |
20130322135 | COMPACT, METHOD FOR PRODUCING COMPACT, REACTOR, CONVERTER, AND POWER CONVERSION DEVICE - A low-loss compact and a method for producing the compact are provided. | 12-05-2013 |
20140191839 | COMPACT | 07-10-2014 |
20140232034 | METHOD FOR MOLDING POWDER MOLD PRODUCT - The present invention relates to a method for molding a powder mold product according to which a powder mold product of uniform quality can be molded with excellent productivity. The present invention includes the steps of: preparing raw material powder | 08-21-2014 |
20150279532 | COMPACT, METHOD FOR PRODUCING COMPACT - 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. | 10-01-2015 |
