  • Patent number: 6591516
    Abstract: A hair dryer including a main body, a centrifugal fan, at least one air inlet and at least one inlet guide. The main body has an air outlet. The centrifugal fan is provided in the main body and configured to blow air toward the air outlet. The centrifugal fan has an intake side and an outer circumferential surface around a central axis of the centrifugal fan. The at least one air inlet is formed in the main body to face the intake side of the centrifugal fan. The at least one inlet guide is provided to project from an inside surface of the main body and extends along a circumference of the at least one air inlet to surround and face a part of the outer circumferential surface of the centrifugal fan along a circumference of the centrifugal fan.

  • Patent number: 5164560
    Abstract: A repulsion type circuit breaker movable contact device comprising a first movable contact, an opening/closing mechanism which drives the first movable contact for opening and closing, a second movable contact for contacting the first movable contact, the second movable contact being freely pivotable and adapted to receive an electromagnetic repulsion force from said first movable contact, and a contact spring comprising a twisted coil spring disposed with its twisting fulcrum displaced from the rotational pivot of the second movable contact, the contact spring urging the second movable contact into contact with the first movable contact, whereby upon flow of a predetermined amount of electric current through the first and second movable contacts, the electromagnetic repulsion force moves the second movable contact apart from the first movable contact.

  • Patent number: 5025236
    Abstract: The present invention is directed toward a circuit breaker having an open-and-close shaft; holding member coupled to the open-and-close shaft; at least one movable contactor coupled to the holding member; support member for rotatably supporting the open-and-close shaft; and stopper member coupled with the support member so as to restrict an open-and-separation position of the movable contactor, wherein the circuit breaker is disposed within a case, the stopper member are formed on side faces of between-phase partitions of the case and a portion of the holding member contacts the stopper member. Thereby, it is possible to improve an insulation function and to lessen the impact between the holding member and the stopper member.
