  • Patent number: 7628546
    Abstract: The object of the present invention is to suppress a decrease in the optical function of a sleeve by ensuring that a liquid chemical substance is not apt to remain on a peripheral surface of the sleeve even when the liquid chemical substance enters a connector. The present invention relates to an optical connector which is connected to an optical plug holding an optical fiber to a terminal end of which a ferrule is attached. The optical connector of the present invention has a guide pipe into which a ferrule is inserted and on an inner circumferential surface of which a supporting portion (a convexity) is formed, a light-emitting device, a light-receiving device, and a sleeve which is positioned by the supporting portion and optically connects the light-emitting device, the light-receiving device and the optical fiber.

  • Patent number: 7476990
    Abstract: An object of the present invention is to provide a linear actuator in which reliability is improved, and performance is also easily improved. The present invention provides a linear actuator including a stator, a movable element having an iron member, and being reciprocatable with respect to the stator, a permanent magnet fixed to the stator so as to be opposed to the iron member, and a coil fixed to the stator. Because both the coil and the permanent magnet are fixed to the stator, electrical current does not have to be supplied to the movable element, and the feeder lines connected to the coil will not be broken due to the movement of the movable element. In addition, the weight of the movable element will not be increased even when the weigh of the permanent magnet is increased in order to obtain high magnetic flux density for improvement in performance. Moreover, because the movable element does not include a magnet, a magnetizing operation does not have to be applied to the movable element.
