|20140084755||ON-VEHICLE ROTARY ELECTRIC MACHINE - An on-vehicle rotary electric machine includes a first member provided with a stator, a rotor, and a housing in which the stator and the rotor is housed, a second member adjacent to the first member in an axial direction, and a third member adjacent to the second member in the axial direction at an opposite side of the first member, and the first member, the second member, and the third member are pierced by a through bolt in the axial direction and are fixed.||03-27-2014|
|20130218366||SYSTEM FOR PROVIDING INFORMATION ON POWER CONSUMPTION AMOUNT OF ELECTRIC VEHICLE - A high-speed calculation of power consumption provided to a driver to figure out whether an electric vehicle is able to reach a destination can be implemented. Solution: A system for providing information on power consumption amount of an electric vehicle includes receiving means for receiving a departure point of the electric vehicle and a destination of the electric vehicle from a terminal device; a database which stores a plurality of power consumption amounts required to move between respective two sections, corresponding to a plurality of combinations of two sections, the combinations including a combination of a first section in a predetermined area including the departure point and the destination, and a second section including a second point in the predetermined area; extracting means which retrieves the database to thereby extract a power consumption amount required to travel from the departure point to the destination; and transmitting means for transmitting information on the power consumption amount extracted by the extracting means to the terminal device.||08-22-2013|
|20130100628||Printed Circuit Board and Electronic Device Using Printed Circuit Board - An electronic device having a press-fit connection for connecting a connector and an electronic part mounted on a printed circuit board which is possible to enable high density mounting. Viewing the printed circuit board from an upper surface, between adjacent through holes on which a compressive force acts upon insertion of the press-fit terminal, among the large number of through holes, a land or a conductor film connected to the conductor film formed on the inner wall surface of the through hole or the conductor film not connected to the conductor film formed on the inner wall surface of the through hole, formed in the circuit board held between the top layer circuit board and the bottom layer circuit board, exists in a width equal to or wider than the diameter of the through hole.||04-25-2013|
|20120008286||Power Conversion Device - A power conversion device according to the present invention includes: a power module (||01-12-2012|
