  • Method and apparatus for measuring temperature in the high pressure furnace of a hot isostatic pressing
    Patent number: 4666314
    Abstract: A method of measuring the temperature in a high pressure furnace of a hot isostatic pressing apparatus, wherein a closed-end pipe having its inside communicated with the inside of the high pressure furnace and enabling a pressure medium to pass therethrough is disposed in the furnace, an incident top end of an optical fiber, a bundle of optical fibers or like other equivalent optical rod-like memeber is disposed to the open end of the closed-end pipe so as to be capable of receiving thermally radiated light from the inside of the closed-ended pipe and an exit rear end thereof is led out through a cover and to the outside of said high pressure vessel and a measuring system is connected to said exit rear end to detect heat radiation power from the top end of the closed-end pipe to thereby measure the temperature inside of the furnace.
    Type: Grant
    Filed: June 6, 1986
    Date of Patent: May 19, 1987
    Assignee: Kabushiki Kaisha Kobe Seiko Sho
    Inventors: Shigeki Tojyo, Tatsuo Uesaka, Yoshio Kawate, Masayoshi Iwaskai, Takefumi Horiuchi, Masato Moritoki, Takeshi Kanda, Takao Fujikawa, Shigeo Kofune
  • Adjusting device for color cathode ray tube
    Patent number: 4295110
    Abstract: A barium ferrite layer is disposed around an external surface of neck portion of a color cathode ray tube to have a magnetic easy axis radially of the longitudinal axis of the neck portion. An electromagnet is revolved around the layer to magnetically charge it so as to correct static convergence and color purity of three electron beams generated in the color cathode ray tube.
