  • Heat transfer tube, heat exchanger, and method for manufacturing heat transfer tube
    Patent number: 11285522
    Abstract: A heat transfer tube is made of aluminum and includes a streak-shaped Zn diffusion layer (6, 106) which is spirally formed on a circular outer peripheral surface in a length direction. According to this heat transfer tube, even in a case where rainwater or dew concentration water is intensively accumulated in a portion of the outer peripheral surface in a circumferential direction, it is possible to obtain a sufficient corrosion resistance.
    Type: Grant
    Filed: November 30, 2017
    Date of Patent: March 29, 2022
    Assignee: Mitsubishi Aluminum Co., Ltd.
    Inventors: Yusuke Nakaura, Yuki Hateruma, Hideo Kume, Takuya Okawa

  • Optical fiber switch
    Patent number: 5175780
    Abstract: An optical switch having two spherical or elliptical corner-reflecting surfaces provided in a light-conducting member, a shutter to open and close a light path between the corner-reflecting surfaces, and focusing lenses to focus the incident beam from an emitting optical fiber and to focus the emitting beam from the light-conducting member to a primary receiving optical fiber. Because almost all the beam transmitted through the light-conducting member is focused at one point in an air gap in which the shutter moves, the optical switch can transmit the beam with high efficiency without leakage to the outside, and a small stroke of the shutter is sufficient to completely transmit or stop the beam.

  • Electric motor fan
    Patent number: 4589827
    Abstract: An electric motor fan comprises a fan driven by a motor, a case with the fan mounted therein and including a scroll providing an air outlet port of the fan, and a control unit including an output transistor for controlling the drive of the motor. The control unit includes a heat radiation device mounted in the scroll for radiating the heat generated by the transistor. At least a part of the heat radiation device is formed as a radiation fin having an internal surface in the same plane as the internal wall surface of the scroll.
