  • Transfer method and device and driving system therefor for transfer presses
    Patent number: 5103965
    Abstract: A trolley is reciprocally moved along a guide. A work support, supported by the trolley, is vertically moved so that the lift mechanism can be made of a compact size, a light weight and highly reliable in operation thereby increasing the processing speed of the processing line and improving productivity.
    Type: Grant
    Filed: June 28, 1990
    Date of Patent: April 14, 1992
    Assignee: Ishikawajima-Harima Jukogyo Kabushiki Kaisha
    Inventors: Yoshio Takahashi, Mitsuo Sudo, Takamasa Arikawa, Kenji Nakamura, Izumi Sato, Katsuyuki Onogi, Takao Iura, Nobuji Ishida

  • Ultrasonic thickness measuring method and apparatus
    Patent number: 5009103
    Abstract: An ultrasonic thickness measuring method and apparatus in which an ultrasonic pulse is transmitted from a probe to a material to be measured and resulting multiple reflection pulses from the material to be measured are detected to obtain a time interval between the reflection pulses for measuring the thickness of the material. This method and apparatus features, for example, comprises counting a time from transmission of the ultrasonic pulse to reception of a first reflection pulse from a bottom of the material to be measured; detecting a pulse received within a preset period of time after said first reflection pulse has been received and just before a time corresponding to the counted time has passed, as a second reflection pulse; and counting a time between the reception of the first reflection pulse and the reception of the second reflection pulse to measure the thickness of the material.
