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 |
