  • Patent number: 8900199
    Abstract: A needle tip protector is configured in such a manner that a flexible plate is provided to a protector main body over which an action ring is mounted and that the flexible plate undergoes flexural deformation when the action ring is moved to a predetermined position relative to the protector main body. When the flexible plate undergoes flexural deformation, a needle tip of an inner needle to which the protector main body is mounted is protected by a protection part placed at a distal end of the flexible plate. The needle tip protector is also provided with a slip-stop mechanism for preventing the action ring from slipping out of the protector main body in an axial direction of the needle.

  • Patent number: 6679003
    Abstract: A door frame structure of a vehicle, of which a door frame is covered with a frame molding. The door frame has a flat peripheral wall extending around a window opening of a vehicle door and a protrusion protruding from an inside end of the flat peripheral wall. The frame molding is composed of a synthetic resin or TPO and is attached to an outside end of the peripheral wall of the door frame. A pair of shelf projections are integrally formed on an inside surface of the frame molding from about a widthwise center thereof so as to be spaced from each other. By press-inserting the flat peripheral wall of the door frame between the shelf projections of the frame molding, the frame molding is secured to the door frame.

  • Patent number: 6655698
    Abstract: A sealing member to be attached along a periphery of a door with a continuous good sealing performance against a facing opening portion even in a corner of the periphery of the door. A bar-shaped magnet is provided in a tubular seal portion of the sealing member so as to extend in a longitudinal direction thereof in close contact with an inside surface of a contacting part of a seal wall, which contacts the facing opening portion. The bar-shaped magnet has a cross-sectional shape of which the width gradually decreases from the side of the contacting part of the seal wall inwardly of the tubular seal portion, thereby reducing the cross-sectional area of the magnet, and enabling the magnet to be readily bent along a corner of the periphery of the door. And the bar-shaped magnet has an outwardly curving contacting surface, which contacts the contacting part of the seal wall, thereby improving contacting properties between the sealing member and a corner of the opening portion.

  • Patent number: 6530618
    Abstract: A sealing structure for forming a seal between a weather strip attached to a door opening portion of a vehicle body, and a periphery of a vehicle door. The weather strip includes a base portion having a generally U-shaped cross-section for attachment to the door opening portion, and a tubular seal portion which expands from an outer side wall of the base portion. A projection is formed in the weather strip so as to project from the outer side wall of the base portion into an interior of the tubular seal portion so as to be spaced from an inner surface of a projecting top of a sealing wall of the tubular seal portion. When the vehicle door is closed, an inside surface of a periphery of a door panel contacts and presses the projecting top of the sealing wall, which faces the projecting end of the projection, while an inside surface of a door frame contacts and presses a side part of the sealing wall apart from the projecting top of the sealing wall.

  • Patent number: 6506005
    Abstract: A method of machining seats of a compressor piston having an approximately hemispherical recess. A surface of a piston extending perpendicular to an axis of the piston is machined by annularly moving a cutting element while the cutting element is rotated with respect to the piston to form an annularly cut portion. The surface is further machined by moving the same cutting element in a direction toward the surface while the cutting element and the piston are relatively rotated to form a hemispherical recess in the surface. The firstly formed annularly cut portion becomes an annular chamfered portion on the periphery of the hemispherical recess. In this way, it is possible to form the hemispherical recess, and the annular chamfered portion on the periphery thereof, with the common cutting tool.
