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 |
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 |
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 |
