  • Patent number: 7607229
    Abstract: An electric razor including an actuator, an outer cutter and an inner cutter. The actuator has a first vibrator and a second vibrator. The outer cutter and the inner cutter are respectively supported at the first vibrator and the second vibrator so that the cutters can slide against each other. The actuator vibrates the first vibrator and the second vibrator so that the vibrators slide in reciprocation toward opposite directions to each other. Even though vibration of the first vibrator is interrupted by external force through the outer cutter, the second vibrator relatively vibrates so as to slide in reciprocation with respect to the first vibrator and therefore it is easy to meet specified shaving performance.

  • Publication number: 20090260354
    Abstract: An axle driving apparatus in which a hydraulic pump and a hydraulic motor which constitute a hydrostatic transmission are disposed on a center section. In a horizontal portion of the center section are provided a pair of linear oil passages in parallel to each other. A pair of arcuate ports are provided on a pump mounting surface formed on the horizontal portion of the center section. The pair of arcuate ports are substantially perpendicular with respect to the direction in which the oil passages extend. The axis of slanting movement of a movable swash plate of the hydraulic pump extends laterally of the vehicle body on which the axle driving apparatus is provided. The rotating direction of an arm provided on a control shaft for slantingly operating the movable swash plate is coincident with the operating direction of a control rod connected with a speed changing member. Thus, the link mechanism for connecting the speed changing member and the control arm for the movable swash plate is simplified.

  • Publication number: 20090126328
    Abstract: The working vehicle with front-mount mower according to the present invention makes it possible to secure, in the center in a vehicle widthwise direction, a free space used for positioning a discharge duct without being affected by a pump-side transmission mechanism that transmits rotational power from a driving power source to a hydraulic pump main body and a PTO-side transmission mechanism that transmits rotational power from the driving power source to a mower. Accordingly, it is possible to improve design freedom of the discharge duct, thereby eliminating the use of or downsizing a blower, which has been vital in the conventional techniques.

  • Publication number: 20090073263
    Abstract: A vehicle periphery monitoring system takes a view image of a vehicle rear periphery, which is in a predetermined area from the vehicle. This view image is converted into a bird's-eye view image and the bird's-eye view image is displayed in a vehicle compartment to assist rearward movement of a vehicle. As the vehicle approaches an obstacle, the bird's-eye view image is formed by increasing an angle of depression of the bird's-eye view image. A masking section is synthesized with the bird's-eye view image to mask a part of the bird's-eye view image not to be viewed. This masking section is increased as the depression angle increases thereby masking the distorted part of the view image.
