  • Patent number: 5468079
    Abstract: A printing apparatus comprises a card transport mechanism for printing on a card-like medium. A slider is provided having a card stop against which one edge of the card stops and a holding mechanism holds the card to the slider. A guide frame is further provided having at least one guide portion engaged with the slider for moving the slider parallel to the guide frame. A motor and transmission mechanism moves the slider, whereon a card-like medium is held by the holding mechanism, along the guide member for printing.

  • Patent number: 5194771
    Abstract: A brushless core motor featuring improved positional relationship between magneto-sensitive elements and core windings to prevent distortion of the output from the elements, enable a reduction in the thickness of the motor, and assure reduced and uniformly distributed leakage of magnetic flux. The motor includes an armature core having a plurality of salient poles, a plurality of windings in "m" phases (the term "m" expresses an integer.gtoreq.two) which are wound on the salient poles, a rotor magnet rotatable in an opposed relation with the salient poles, and "n" magneto-sensitive elements (the term "n"=an integer satisfying the relation of m.gtoreq.n) for detecting the magnetic poles of the rotor magnet in order to effect electric conduction control of the windings in the m phases. The magneto-sensitive elements are disposed in the vicinity of the rotor magnet, and, of the salient poles, having no windings are disposed adjacent the magneto-sensitive elements.

  • Patent number: 4967999
    Abstract: A flow passage coupling unit is provided for connection and disconnection of pipings e.g. on a tooling die exchanger of a press or a former machine, in which both the cylindrical body and the valve head of a slide valve actuated for communication and discommunication between flow paths are slidably fitted into the small and large diameter bores of a main body respectively which is designated as a housing for the slide valve, so that the sliding distance of the slide valve can be determined by summing up of the sliding lengths of their respective small and large diameter bores. Accordingly, the entire length of the main body is minimized and thus, the flow passage coupling unit will become compact in size while assuring consistent action in coupling the flow passages. Also, the flow passage coupling unit is further reduced in the overall size by improviding both the sealing arrangement in the sliding regions and the opening arrangement in the cylindrical body.

  • Patent number: 4962881
    Abstract: A flow passage coupling unit (1) for flow passages (2, 4) of movable and fixed members (3, 5), which includes a cylindrical body (6) secured to the movable member and having a large bore (10) communicating with the flow passage, a small bore (11) and a value seat (12) formed between the large and small bores; a sliding valve (7) having a cylindrical sliding surface (7a) which slidably fits in the small bore and has an axial passage (14), a valve head (17) movable within the large bore, and a through-hole (16) provided through the cylindrical sliding surface adjacent the valve head; a coil spring (13) provided within the large bore for biasing the valve head against the valve seat so that communication between the large bore and the axial passage is normally cut off; and the valve seat (12) made in a plane which is perpendicular to an axis of the sliding valve.

  • Patent number: 4903730
    Abstract: A pipe coupling consisting of a male and female elements for connecting and disconnecting a hydraulic or pneumatic piping used for industrial machinery. Each coupling element includes a check valve therein which is actuated by connecting and disconnecting operation to automatically open the passageway of the coupling when it is connected and to automatically close it when it is disconnected. The inventive pipe coupling is designed to be used with a conventional automatic connecting and disconnecting device such as automatic coupling device for large scaled industrial machinery.
