|20140241927||VANE-TYPE HYDRAULIC DEVICE - A vane pump (||08-28-2014|
|20140083804||DISK BRAKE DEVICE - A disk brake device has a rotor having a braking surface, a caliper, an outer pad and an inner pad each disposed to face the braking surface, and a braking operation mechanism which performs an operation of pressing the two pads against the braking surface. The braking operation mechanism includes a base plate, a wedge plate which holds the inner pad, a first movement conversion mechanism which moves the wedge plate in a direction perpendicular to the braking surface, while moving the wedge plate to slide relative to the base plate in a rotating direction of the rotor in parallel to the braking surface, an electric motor unit which outputs a rotational driving force, and a second movement conversion mechanism which moves, using the rotational driving force of the electric motor unit, the wedge plate to slide in the rotating direction of the rotor in parallel to the braking surface.||03-27-2014|
|20140079375||ELECTRIC HEATING DEVICE AND ELECTRIC VEHICLE - An electric heating device suitable for heating an electric vehicle and having a novel structure is provided. The electric heating device includes: an electric motor that includes a stator having a plurality of stator coils arranged along the circumferential direction to generate a rotating magnetic field and a disk-shaped rotor that includes a plurality of one-turn coils disposed correspondingly to the stator coils and a soft magnetic metal plate supporting the one-turn coils; and a fan secured to the soft magnetic metal plate on a side thereof opposite from the one-turn coils and including a vane wheel that has a plurality of vanes and rotates integrally with the rotor.||03-20-2014|
|20120240893||ENGINE LUBRICATING OIL SUPPLY DEVICE - An engine lubricating oil supply device (||09-27-2012|
|20120082581||GEAR PUMP - In a gear pump according to the present invention, a wall surface portion of a casing (||04-05-2012|
|20120076637||VARIABLE FLOW RATE PUMP - A water pump (||03-29-2012|
|20110248664||ENERGY CONVERTER - An energy converter includes a magnetism generation mechanism unit that generates a magnetic field when connected to an AC electrical power source, and a rotating mechanism unit having a single turn coil array member in which a plurality of single turn coils is disposed at a predetermined interval and a soft magnetic metal plate disposed on a side of the single turn coil array member opposite to the magnetism generation mechanism unit. The rotating mechanism unit is structured such that the single turn coil array member faces the magnetism generation mechanism unit across a predetermined magnetic gap and rotary driven by the magnetic field. Here, a drive signal period of the electrical power source is a period that maximizes an eddy current generated in the soft magnetic metal plate.||10-13-2011|
|20100086422||GEAR PUMP - An oil pump includes a drive gear, which rotates with a drive shaft, a driven gear, which meshes with the drive gear and is supported rotatable on a driven shaft, and a casing having a pump chamber, which accommodates the drive gear and the driven gear. The casing of the gear pump is provided with an intake port and a discharge port, which are in fluid communication with the pump chamber, so that oil is sucked through the intake port and discharged through the discharge port. A gear holder is provided in the casing such that the gear holder supports the driven gear rotatable and holds both sides of the driven gear while the gear holder itself is being supported axially movable by the driven shaft. The gear holder holding the driven gear moves axially by receiving a biasing force and also a pressing force acting against the biasing force.||04-08-2010|
|20080317595||Fluid Pump - A pump pulley is supported on a pump body via a bearing interposed between the outer peripheral surface of the pump body and the pump pulley so that the pump pulley can freely rotate relative to the pump body. A pump shaft extends along the rotation axis of the pump pulley into a pump chamber formed by a pump base and the pump body, and one end of the pump shaft is fitted to the pump pulley and the other end is fitted to an impeller located within the pump chamber. A body side seal member and a shaft side seal member that form a mechanical seal to maintain the leak tightness of the pump chamber are in opposite to and contact each other in the direction of extension of the pump shaft to form a seal surface, and the plane that includes the load support center of the bearing and the plane that includes the seal surface of the mechanical seal are substantially coincidental.||12-25-2008|
