  • Publication number: 20060138255
    Abstract: A tip end surface of a valve body and a back end surface of an injection nozzle contact each other with pressure by being fastened using a retaining nut and thereby form a metal seal structure to achieve a metal seal. To increase a surface pressure in a seal surface by fastening axial force, conventional recesses around the central axis of a nozzle are replaced so that proximity of a high pressure fuel hole is secured as a seal surface. An outside recess is provided outside of the proximity of the high pressure fuel hole to link with an outer peripheral border of the metal seal structure. Alternatively, a contact surface functioning as a retaining seal surface is added outside of the outside recess to be apart from the proximity of the high pressure fuel hole.

  • Patent number: 5937959
    Abstract: A conveyance apparatus, and more particularly, an improvement of a transfer aid mechanism which allows a patient to be transferred from a bed to a wheelchair, for example, is disclosed. The transfer aid mechanism according to the invention includes casters disposed at four locations on a frame, and a drive mechanism which is elevatable with respect to the frame. When required, the drive mechanism is lowered to bring its drive wheel into contact with a floor, and when the drive wheel is driven for rotation under this condition, the transfer aid mechanism may be moved back and forth by utilizing the drive wheel alone. Accordingly, a travelling movement of the transfer aid mechanism is facilitated if there is a carpet laid over the floor or there is a step in the floor.

  • Patent number: 5309362
    Abstract: A driving torque controlling system by which a vehicle can drive with safety and certainty while maintaining an appropriate posture without dissatisfying the will of a driver very much. The driving torque controlling system comprises a control signal selecting section which selects, in response to a predetermined change-over condition, one of control signals from a turning control unit for setting an aimed driving torque in response to a magnitude of lateral acceleration applied to the vehicle during turning of the vehicle and a slip control unit for setting an aimed driving torque in response to an amount of slip of a driving wheel of the vehicle. A torque controlling unit receives a selected control signal from the control signal selecting means and reduces the driving torque of the vehicle in response to the received control signal independently of operation by a driver of the vehicle.

  • Patent number: 5284222
    Abstract: A speaker cabinet in which a cross section of an outer peripheral portion (11) is formed as an elliptic shape and opening portions (22 to 25) formed on the outer peripheral portion (11) and into which speakers (2 to 5) are mounted are formed as horn shapes whose diameters are improved toward the outside. The speaker cabinet includes a plywood member (10) that is formed by laminating a hard plate member, a soft plate member and a light and soft rear surface plate member on a face front surface plate member. The cabinet is molded in a predetermined curved fashion to have an elliptic shape. Thus, an acoustic characteristic of the speaker cabinet can be increased and a manufacturing cost of the speaker cabinet can be reduced.

  • Patent number: 5276624
    Abstract: In a turning control apparatus for a vehicle, a torque calculation unit calculates a target lateral acceleration of the vehicle according to detection signals from a steering angle sensor for detecting the direction of a steering wheel and a vehicle speed sensor for detecting the speed of the vehicle. It then sets target driving torque of the engine according to the target lateral acceleration. An electronic control unit controls the operation of a torque control device for reducing driving of the engine so that the driving torque of the engine is a target driving torque independent of manipulation by the driver. This thereby rapidly estimates lateral acceleration applied to the vehicle during turning and prevents control delay to enable stable and positive traveling through a curved road.
