  • Patent number: 7208113
    Abstract: To provide a method of producing an encapsulating molding material tablet by which adhesion of an encapsulating molding material to the punch surface of a tablet forming machine can be reduced, an encapsulating molding material tablet produced by this method, and an electronic part apparatus equipped with an element encapsulated using this encapsulating molding material tablet. A method of producing an encapsulating molding material tablet in which a release agent dissolved in a solvent is fed to the punch surface of a tablet forming machine to form a release agent layer having a thickness of over 0.001 ?m and less than 0.07 ?m on the above-mentioned punch surface, then, an encapsulating molding material is fed to the above-mentioned tablet forming machine for molding the material, an encapsulating molding material tablet produced by this method or having a contact angle ratio of 1.15 or more and less than 1.

  • Patent number: 4422263
    Abstract: A toy vehicle is disclosed including a gear changing mechanism for use in conjunction with a flywheel driving device. The mechanism comprises a gear changing lever pivotally mounted to a frame by means of a pin. The lever is biased in one direction by means of a first spring member to hold the axle of an idle gear in engagement with one end of an elongated opening formed in the frame. The gear changing lever is adapted to pivot by a depressing action against the force of the first spring member to disengage the idle gear axle from the one end of the elongated opening so as to allow a second spring member to urge the idle gear axle against the other end of the elongated opening.
