  • Joint for joining two coaxial shafts
    Patent number: 7226235
    Abstract: A joint, usable as a component of a golf club, including an outer sleeve having a proximal end, a distal end, an outer surface and an inner surface; an inner sleeve having a proximal end, an outer surface in circumscribing contact with the inner surface of the outer sleeve, a slit, and a projection ring having an inner diameter; and an inner projection having a proximal end sized to be in circumscribing contact with the inner surface of the inner sleeve, a distal end, a key sized to be slidably fit in the slit of the inner sleeve, a proximal taper, a distal taper and a maximum diameter, the maximum diameter being larger than the inner diameter of the projection ring, the maximum diameter being selectively passable through the projection ring.
    Type: Grant

  • Small-sized and precision injection molding apparatus
    Patent number: 4723898
    Abstract: In a small-sized and precision injection molding apparatus, a raw material supply means, a raw material plasticization means, an injection plunger means and a melted resin flow passage means are all together incorporated in a mold, thereby a substantial distance from the raw material up to a cavity becomes shorter. Thus, an overall construction of the injection molding apparatus becomes small-size and compact.
