  • Patent number: 5639403
    Abstract: A molded article is formed by an injection molding method of embedding a workpiece within a resin by the use of a mold. The mold has a mold cavity, at least one supporting pin removably projecting into the mold cavity to support the workpiece in the mold cavity, and at least one gate for injecting the resin into the mold cavity. The supporting pin is forced against the workpiece to support the workpiece within the molded cavity. The resin is injected into the molded cavity through the gate. In the present method, the supporting pin is removed from the mold cavity after the workpiece is supported by pressure of the resin injected in the mold cavity. The injection of the resin is continued to fill a hole left in the mold cavity by removal of the supporting pin. After the injection is finished, the injected resin is hardened to obtain the molded article.

  • Patent number: 5023414
    Abstract: An electrical rotary switch in use with an automatic transmission for detecting the operative position of the transmission and controlling an electric circuit associated with the positions of the transmission. The switch comprises a switch casing composed of a base plate and a cover plate each formed of an electrically insulating material and provided in its interior surface with a plurality of fixed contacts. Supported between the base plate and the cover plate is an actuator which is rotatable about a rotation axis in response to the changing positions of the automatic transmission. The actuator has a coupling end to be interlocked with a control output shaft of the transmission which is provided to rotate in synchronism with changing positions of the transmission.

  • Patent number: 4298779
    Abstract: A rotary type microswitch wherein a rotary handle member having at its body periphery a handle for driving a free end of a movable contact spring plate carrying a movable contact opposed to a stationary contact is rotatably borne at both axial ends between opposing side walls of a housing, and a lever member receiving an external operating force for rotating the handle member is coupled on a desired side of the housing to either one of the both ends of the handle member which are exposed to the exterior of the side walls. With the handle member thus providing a free selectivity in operating-force applying direction with respect to the both ends at which the member is borne, stably reliable switching operation is obtained. Such operation is further assured to be achieved with a smaller operating force due to the fact that a slidable card is inserted between the free end of the movable contact spring plate and the handle.
