20150307800 | SLIDING MEMBER - There is provided a sliding member that has sufficient wear resistance and good adhesion to a base formed of a sintered body. The sliding member includes a surface layer formed of a crosslinked fluoropolymer and a base that adheres closely to the surface layer. The base is a sintered body having a full density ratio in the range of 0.75 to 0.96 and is formed of a material having higher thermal conductivity than a fluoropolymer. The surface layer has a thickness in the range of 1 to 300 μm. | 10-29-2015 |
20140199198 | INTERNAL GEAR PUMP - An internal gear pump includes an inner rotor having n teeth and an outer rotor having (n+1) teeth. A tooth profile of the inner rotor is an envelope of a group of locus circles ( | 07-17-2014 |

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 |
20130271256 | DUST CORE, METHOD FOR MANUFACTURING THE SAME, AND COIL COMPONENT - A method includes a step of compacting an insulation-coated pure iron powder or an iron-based alloy powder mainly containing iron using a die to obtain a dust core, a step of heat-treating the obtained dust core, and a step of post-machining at least one portion of the heat-treated dust core using a grinding wheel. In the post-machining step, grinding is performed in such a manner that the dust core and the grinding wheel are rotated, whereby isotropic machining marks are formed on a machined surface of the dust core. | 10-17-2013 |
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 |
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 |
20120177525 | PUMP ROTOR AND INTERNAL GEAR PUMP USING THE SAME - An object is to meet the demands for increasing the number of teeth of a rotor in an internal gear pump while maintaining a theoretical discharge amount by using an equivalent body configuration so as to enhance the pump performance relating to discharge pulsation due to the increased number of teeth. In a pump rotor | 07-12-2012 |
20100229395 | METHOD FOR MANUFACTURING RIGID INTERNAL GEAR OF WAVE GEAR DEVICE - A method for manufacturing a rigid internal gear of a wave gear device in which an internally toothed portion formed with internal teeth and a gear main body portion are joined integrally, the method including preforming an internal teeth-forming ring or disc for forming the internally toothed portion by using a first aluminum alloy powder; manufacturing a forging in which the internal teeth-forming ring or disc is placed in a forging die and is integrally formed on its outer side with the gear main body portion using a second aluminum alloy powder, the first aluminum alloy powder being harder and having higher abrasion resistance than the second aluminum alloy powder; and applying post-processing including cutting teeth to the forging. | 09-16-2010 |
20100209276 | INTERNAL GEAR PUMP ROTOR, AND INTERNAL GEAR PUMP USING THE ROTOR - Flexibility is given in setting the tooth depth and the number of teeth of a pump rotor 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 the increase of the tooth depth. At least one of an addendum curve and a dedendum curve of an inner rotor ( | 08-19-2010 |
20090197782 | SOFT MAGNETIC MATERIAL AND DUST CORE - A soft magnetic material includes a plurality of composite magnetic particles including a metal magnetic particle and an insulating film surrounding a surface of the metal magnetic particle. The insulating film also contains a phosphate. The soft magnetic material further includes an aromatic polyetherketone resin and a metallic soap and/or an inorganic lubricant having a hexagonal crystal structure. The metallic soap and the inorganic lubricant are particles with an average particle size of not more than 2.0 μm. | 08-06-2009 |
