  • 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: 5566072
    Abstract: An apparatus for estimating a road traffic condition and for controlling a vehicle running characteristic includes a controller having a fuzzy inference function and a neural network function. The controller carries out frequency analysis on vehicle driving parameters such as vehicle speed, steering angle, accelerator opening degree, and longitudinal acceleration and lateral acceleration of a vehicle, to thereby determine a mean value and variance of each parameter. It implements fuzzy inference based on a traveling time ratio, an average speed, and an average lateral acceleration, which are obtained from vehicle speed and/or steering angle, to thereby calculate road traffic condition parameters, including a city area degree, a jammed road degree, and a mountainous road degree.
