20110156512 | STATOR FOR ROTATING ELECTRIC MACHINE AND MANUFACTURING METHOD FOR THE SAME - The present invention relates to a rotating electric machine stator that includes connecting members for connecting jumper wires to each other between neighboring magnetic pole coils of the rotating electric machine stator, and its manufacturing method. In a conventional connecting member, its portions to be connected to the jumper wires are figure-U shaped and have openings on the opposite side to a core's end-face where the jumper wires are disposed, so that, in order to insert the jumper wires into the openings, complex drive controls have been required for the connecting portions being figure-U shaped. In order to simplify the drive controls, such connecting portions being made in curved shapes have openings each facing the end-face of a core. It is possible to generally apply the present invention to rotating electric machine stators that obey coil connection specifications. | 06-30-2011 |

20090011300 | FUEL CELL SYSTEM AND CONTROL METHOD THEREOF - In a fuel cell system, mixture fuel having a certain fuel concentration is supplied to an anode, electric power is output from between the anode and the cathode due to electrochemical reaction when the cathode makes contact with air, and unreacted fuel containing unreacted fuel is discharged from the anode. A fuel circulating path for circulating the unreacted fuel to the anode is connected to the power generating unit and fuel is supplied from the fuel supplying unit to the fuel circulating path depending on a reduction in pressure of the mixture fuel. The temperature of the power generating unit is controlled according to the concentration of the mixture fuel supplied to the anode. Consequently, a fuel cell system, which can achieve reduction of the size thereof without dropping fuel usage efficiency, can be provided. | 01-08-2009 |
