  • Patent number: 11911820
    Abstract: A gap control part controls a clamping device so that mating surfaces in a die face each other across a gap, and thereby a cavity and an external part of the die communicate across the gap. A molten metal feed control part controls a molten metal feed device so as to feed molten metal into a sleeve when the gap is being maintained. An injection control part controls an injection device so as to start a forward movement of a plunger at a time when the gap is maintained and there is the molten metal in the sleeve. A clamping control part controls a clamping device so as to make the mating surfaces abut against each other to eliminate the gap after the forward movement of the plunger is started and before the molten metal reaches a molten metal surface height at which the molten metal flows into the gap.

  • Patent number: 11152023
    Abstract: A manufacturing method of a disc device suspension includes forming a load beam blank including the load beam and a first frame continuous to the load beam, forming a flexure blank including the flexure and a second frame continuous to the flexure, forming a convex portion in the first frame, forming an opening in the second frame in a position corresponding to the convex portion to receive the convex portion, overlapping the load beam blank with the flexure blank to insert the convex portion into the opening, fixing the flexure to the load beam, and separating the load beam from the first frame and the flexure from the second frame after the fixing.

  • Patent number: 9592352
    Abstract: An ultrasound-guided piercing needle constituting the internal needle of an indwelling needle has ridged and grooved portions which reflect ultrasonic waves. The ridged and grooved portions comprise grooves, which are disposed on the outer periphery near the tip having a blade face, and ridges, which are arranged on both sides of the grooves.

  • Publication number: 20160022977
    Abstract: A method of manufacturing a cap including a top face ring having an opening on the center thereof and a peripheral wall extending from the outer peripheral edge of the top face ring and directly or indirectly attached to a housing . When the cap is injection molded, a molten resin is injected from a center gate of a cavity of a circular plate located on the opening of the top face ring, allowed to radially flow to fill a cavity of the top face ring, and allowed to further flow to fill a cavity of the peripheral wall to form a molded body.
