  • Patent number: 8587177
    Abstract: A stator includes a stator core and a distributed winding type multi-phase coil. This coil includes unit coils made by winding a flat conductor wire in plural turns. The unit coils are mounted in slots of the stator core and connected with each other. Each unit coil includes an outer-layer coil and an inner-layer coil each being concentrically wound. Those two layer coils are made of a single continuous flat conductor wire. A winding start portion of the outer-layer coil and a winding end portion of the inner-layer coil form first and second connection end portions of the unit coil respectively. The first and second connection end portions are located separately on both edges of the unit coil above an upper end face of the stator core. The first connection end portion is placed close to an inner circumference of the stator core and the second connection end portion is placed close to an outer circumference of the stator core.

  • Publication number: 20130291814
    Abstract: In an intake valve timing control apparatus, a lock member is arranged to lock a vane rotor with respect to a housing when the vane rotor is in a most retarded position within which rotation of the vane rotor is restricted by a stopper mechanism. In an exhaust valve timing control apparatus, a lock member is arranged to lock a vane rotor with respect to a housing when the vane rotor is in a most advanced position within which rotation of the vane rotor is restricted by a stopper mechanism. The exhaust valve timing control apparatus further includes a biasing member arranged to bias the vane rotor with respect to the housing in a direction toward the most advanced position. In each valve timing control apparatus, a housing body of the housing and a vane rotor are formed by extruding an aluminum-based metal.

  • Publication number: 20130233261
    Abstract: Even if an internal combustion engine is stopped having a lock pin of a vane rotor kept disengaged from a lock recess, subsequent engine starting can instantly move the vane rotor to a desired angular position where the lock member an be engaged with the lock recess. The vane rotor has therein two passage control mechanisms each having a hydraulically actuated valve body. When the valve body is moved to a given position, retarding and advancing hydraulic holes become communicated to each other through an annular groove of the valve body. Due to this ON communication, retarding and advancing operation chambers become communicated, so that reciprocative swing movement of the vane rotor induced by an alternating torque produced at the starting of the engine is effectively made and thus the vane rotor can be quickly turned to the desired angular position for ease of engine starting.

  • Publication number: 20130238176
    Abstract: In order to minimize a calculation load and surely obtain a maximum adhesion torque, estimated adhesion torques are always stored, an maximum value is obtained from the stored plural estimated adhesion torques immediately before slip/skid is detected when detecting the slip/skid, and the maximum value is set as a maximum adhesion torque. The maximum adhesion torque immediately before the slip/skid is detected is compared with a value of the estimated adhesion torque when the slip/skid is detected. When the calculated value exceeds a threshold value, it is determined as a condition where an adhesion coefficient drastically drops, and a suppression/return ratio of the torque is switched to a lower value than that under a condition where the adhesion coefficient does not drastically drop. The value of the torque at the time of suppression or return is set to a smaller value to surely suppress the slip/skid.

  • Patent number: 8492004
    Abstract: The invention provides a friction joining structure comprising steel products, a friction joining steel plate inserted there between, and a fastening device, which are mutually friction joined by a compressive force derived from the fastening device. A portion of projected streaks on the friction joining steel plate is designed to have a Vickers hardness at least 3 times greater than the surface of the steel products, which allows the projected streaks to more easily enter the steel products thereby increasing the friction coefficient between the steel products. The friction joining structure is constituted by a slip resistance mechanism which can be easily validated from a theoretical or an experimental point of view and is also small in variance of the friction coefficient. Therefore, a friction coefficient used in design can be set at a high value with high accuracy to realize a rational design.

  • Publication number: 20130175344
    Abstract: The purpose of the present invention is to reduce costs for biological sample measurement devices by means of providing a novel method for easily and reliably identifying types of biological sample measurement sensors. Specifically, the present invention provides a biological sample measurement device provided with a main body case, a sensor insertion port, a connector, a light-emitting element and a light-receiving element disposed inside of the main body case in the vicinity of the connector, and a connector terminal. The light-emitting element can irradiate light onto a biological sample measurement sensor attached to the connector. The light-receiving element can receive reflected light or transmitted light from the biological sample measurement sensor attached to the connector. The type of the biological sample measurement sensor is identified on the basis of the light received and recognized by the light-receiving element.

  • Publication number: 20130146005
    Abstract: In a valve timing control apparatus configured to enable rotary motion of a vane rotor relative to a housing, a recessed-groove passage is formed in the inside end face of the housing. A circumferential length of the recessed-groove passage is dimensioned to be greater than a circumferential width of the associated vane. The recessed-groove passage permits fluid-communication between a phase-advance hydraulic chamber and a phase-retard hydraulic chamber by way of both circumferential ends of the recessed-groove passage at a maximum phase-retard position of the vane rotor relative to the housing.

  • Publication number: 20130139628
    Abstract: A method forms ball recirculation and rolling grooves at an inner circumferential surface of a nut for ball screw use in a state free of deviation in axial, circumferential, and radial nut directions. A flange end face is formed with a concave part, then an inner circumferential surface of a blank and an end face and outer circumferential surface of the flange are continuously ground. Due to this, the coaxiality of the blank inner circumferential surface and the flange outer circumferential surface, and the perpendicularity of the flange end face to the blank inner circumferential surface, are made smaller. The blank is plastically worked to form the ball recirculation groove and is cut to form the ball rolling groove while using the concave part as a phase reference, the end face as an axial direction reference, and the outer circumferential surface as a radial direction reference.
