  • Publication number: 20130078330
    Abstract: A precision press device and a press load control method is provided for downsizing a vacuum chamber in press work in the vacuum chamber, shortening a time required to reach a vacuum and performing high accuracy pressure control. A pressure sensor is set up outside the chamber 16 and a cylinder chamber 17 is formed to allow a tubular plunger 7 to slide up and down. A negative pressure 22 in the chamber 16 attracts the pressurized section 2 and the pressurizing section 1, but by injecting an equivalent pressure 19 of a fluid into the cylinder chamber 17, pushing out the tubular plunger 7, the attractive forces are canceled out.

  • Patent number: 8387526
    Abstract: The present invention provides a precision press device and a press load control method thereof for downsizing a vacuum chamber in press work in the vacuum chamber, shortening a time required to reach a vacuum and further performing high accuracy pressure control. To downsize a chamber 16, a pressure sensor is set up outside the chamber 16 and a cylinder chamber 17 is formed to allow a tubular plunger 7 to slide up and down using the tubular shape of the chamber 16. A negative pressure 22 in the chamber 16 attracts the pressurized section 2 and the pressurizing section 1 to each other, but by injecting an equivalent pressure 19 of a fluid into the cylinder chamber 17, pushing out the tubular plunger 7, the attractive forces are canceled out.

  • Publication number: 20120313001
    Abstract: Provided are an image synthesizing device and an image synthesizing method wherein a subject is less affected by beam absorption. A diffraction beam intensity and a front diffraction beam intensity actually detected are included in the influence of absorption on a subject (Sa). Yet, assuming that said beams have the attenuation rate which is caused by said beams being absorbed when passing through a subject, the angle of refraction ?0 of the beam when passing through the subject (Sa) is obtained using the diffraction beam intensity and the front diffraction beam intensity which are not affected by attenuation, and which are represented by the aforementioned attenuation rate, front diffraction beam intensity, and diffraction beam intensity; a synthesized image of the subject (Sa) is obtained by means of said angle of refraction ?0.
