  • Patent number: 11414898
    Abstract: An automobile door latch device includes: a mesh mechanism; a body; a base; and an operation mechanism disposed on the base, the operation mechanism including: an outside lever configured to receive an operating force of an outside handle to perform open actuation; a first open lever configured to perform open actuation in conjunction with open actuation of the outside lever; a locking/unlocking mechanism; a second open lever configured to perform open actuation in conjunction with open actuation of the first open lever output from the locking/unlocking mechanism; and a fully open release lever configured to perform open actuation in conjunction with open actuation of the first open lever, wherein the fully open release lever is connected to an operating force transmission member configured to transmit the open actuation of the fully open release lever to a fully opening latch device for holding the slide door in a fully open position.

  • Publication number: 20100148387
    Abstract: A process for production of a heat-resistant hollow article made of a polylactic acid containing resin by using a mold which includes a female mold portion having a concavity, a male mold portion having a convexity and a stripper plate having an edge-forming part. The surface of the mold facing the cavity is heated to a temperature corresponding to a crystallization temperature of the polylactic acid containing resin. The male mold portion and the stripper plate are moved away from the female mold portion when a temperature T(° C.) of the resin detected by an infrared temperature sensor is in the range of T=(t+3.5)±1.5 (t(° C.) is the surface temperature of the mold). Gas is introduced between an inner surface of the hollow article and the male mold portion, and the hollow article is taken out of the mold by advancing the stripper plate toward the hollow article.

  • Publication number: 20090008838
    Abstract: Provided is a process for the production of heat-resistant hollow articles that does not cause the deformation of injection-molded products or the incapability of the same being taken out of a mold. A mold 1 that comprises a female mold portion 3 having a concavity 2, a male mold portion 5 having a convexity 4, and a stripper plate 7 having an edge-forming part 6, is heated so that the temperature of a surface facing a cavity 8, which is enclosed by the concavity, convexity, and edge-forming part becomes the crystallization temperature of a polylactic acid containing resin, and the polylactic acid containing resin is injected via a gate 9.

  • Patent number: 5919012
    Abstract: There is provided a method of three-dimensionally cutting a mold including the steps, in sequence, of (a) rotating a single ball end mill at a rate in the range of 50,000 rpm to 200,000 rpm, the ball end mill being made of material having high thermal resistance, (b) driving the ball end mill in horizontal, reciprocating movement at a rate in the range of 10 m/min to 100 m/min, and driving the ball end mill in transverse movement at a predetermined depth of cut in a direction perpendicular to a direction in which the ball end mill is reciprocated, at opposite ends of the reciprocating movement to cut a workpiece in a surface thereof at a common depth of cut, and (c) vertically feeding the ball end mill at a predetermined depth of cut. This method makes it possible to significantly increase a rotation speed and a feeding speed of a cutting tool to thereby remarkably reduce time necessary for cutting a mold.
