20110123877 | CATALYST FOR OXYGEN REDUCTION ELECTRODE AND OXYGEN REDUCTION ELECTRODE - An oxygen reduction catalyst and the catalyst as an electrode catalyst are provided. The oxygen reduction catalyst is characterized by including an organometallic polymer structure in which a transition metal or zinc is coordinated with an organic polymer compound including a ligand comprising a heterocyclic 5-membered ring or a heterocyclic 6-membered ring containing at least not less than two elements selected from nitrogen (N), oxygen (O), sulfur (S), and selenium (Se), and derivatives thereof. Thereby, even when an amount of a metal is smaller than that in a platinum particulate catalyst, an oxygen reduction capacity equal to or more than that of the platinum particulate catalyst can be obtained. Further, by coordinating a metal with an organic polymer, stability in an oxygen reduction condition can be significantly improved compared to the case of metal based macrocyclic compounds. | 05-26-2011 |

20120206007 | ROTOR CORE FOR ROTATING ELECTRICAL MACHINE, AND MANUFACTURING METHOD THEREOF - A cylindrical rotor core | 08-16-2012 |
20130127283 | ROTOR OF AN ELECTRIC MOTOR AND MANUFACTURING METHOD OF SAME - A rotor of an electric motor is provided in which a cylindrical rotor core that is formed by stacked magnetic steel sheets and includes permanent magnets is crimp-fixed to a rotor shaft. The rotor core is directly fixed, in the axial direction of the rotor shaft, between a flange portion that is provided on an outer periphery of the rotor shaft and abuts against one axial end surface of the rotor core, and a crimping member that is crimp-fixed on the rotor shaft while pressure-contacting the other axial end surface of the rotor core. | 05-23-2013 |
20160006313 | STATOR FOR ROTARY ELECTRIC MACHINE - The stator includes a stator core, a plurality of phase windings, a neutral line and a fixing member. The plurality of phase windings are wounded a plurality of times by a predetermined winding method crossing between a plurality of slots. One lead end of each phase winding is supplied with a phase current. The other lead end of each phase winding is a neutral point connecting portion. The other lead end is pulled out from an axially end portion of the stator core. The neutral line connects the neutral point connecting portions of the phase windings of different phases together. The neutral line is separate from the phase windings. The fixing member fixes the neutral line to a yoke portion via an intermediate member. The intermediate member is made of resin. | 01-07-2016 |
20160006314 | STATOR FOR ROTARY ELECTRIC MACHINE - A stator includes a stator core, a plurality of phase windings, a neutral line and a fixing portion. The plurality of phase windings is wounded a plurality of times by a predetermined winding method crossing between a plurality of slots. One lead end of each phase winding is a neutral point connecting portion, and the one lead end is pulled out from an axially end portion of the stator core. The neutral line connects the neutral point connecting portions of the phase windings of different phases together. The neutral line is separate from the phase windings. The fixing portion fixes a first phase winding that is connected to the neutral line. A second phase winding is adjacent to the first phase winding together. | 01-07-2016 |
