  • Publication number: 20190285339
    Abstract: A raw material gas liquefying device includes a feed line; a refrigerant circulation line; and a controller. In a refrigerant liquefaction route, a refrigerant flows through a compressor, a heat exchanger, a circulation system JT valve, a liquefied refrigerant storage tank, and the heat exchanger, and returns to the compressor. In a cryogenic energy generation route, the refrigerant flows through the compressor, the heat exchanger, an expansion unit, and the heat exchanger, and returns to the compressor. The controller determines if a refrigerant storage tank liquid level is within an allowable range, manipulates a feed system JT valve opening rate to control refrigerant temperature at the high-temperature-side refrigerant flow path exit side of the heat exchanger, and manipulates the opening rate of the feed system JT valve to control the refrigerant storage tank liquid level so that the refrigerant storage tank liquid level falls into the predetermined allowable range.

  • Patent number: 5739533
    Abstract: A radiation detector has a film-like pyroelectric element which has a fan shape, and two support plates which are made of an electrical and thermal insulating resin and adhered to the both ends elongating from the pivot of the fan shape to the peripheral portion. After a radiation absorbing layer is attached to one face of the pyroelectric element, the resin plates are adhered to each other so that the layer is positioned inside and the pyroelectric element is formed into a conic shape, thereby forming a conic portion. Radiation entering an opening of the bottom face of the conic portion is absorbed by the layer in the form of heat. The temperature rise is converted by the pyroelectric element into an electric signal, thereby detecting the energy amount of the radiation. A reflected component of radiation entering the layer again enters the layer. Since the input radiation is repeatedly reflected and absorbed by the layer, the radiation is absorbed and detected with about 100% irrespective of the wavelength.

  • Patent number: 5151609
    Abstract: The solid shape of an object is detected by viewing the objects along a Z-axis direction. A plurality of images of the object are picked up at different focus levels having correspondingly different Z-axis coordinate values. Focus measure values are calculated with respect to each of the pixels that are in each of the object images and that are designated by the same X- and Y-coordinate values. The focus measure values of the pixels in the object images having the same X- and Y-coordinate values are compared with each other to detect maximum focus measure values. The solid shape of the object is then estimated based on the Z-coordinate value of the focus level of the object image having the maximum detected focus measure values.

  • Patent number: 5059559
    Abstract: The present invention relates to a multi-pin chip mounting method and apparatus based on a TAB (Tape Automated Bonding) system in which leads formed on a tape and bumps formed an IC chip are aligned with each other and compress-bonded to each other. An IC chip having bumps formed on a surface thereof and inner leads formed on a carrier tape are disposed opposite to each other at a bonding station. A position of the IC chip on a stage is detected through the inner leads at the bonding station to determine the amount of correction of position of the stage. The inner leads and the IC chip are aligned with each other on the basis of the determined correction amount and are thereafter bonded to each other.

  • Patent number: 4872187
    Abstract: In an X-ray tomographic imaging system and method, an object to be inspected is irradiated with X-rays from an X-ray source to obtain an X-ray transmission image of the object. The X-ray transmission image is converted by an X-ray fluorescence image intensifier into a detection image. The intensity of the detection image is also intensified by the X-ray fluorescence image intensifier. A photo-electric converter converts the intensified detection image from the X-ray fluorescence image intensifier into an electrical signal. The object to be inspected is held by an object holder rotatably at a position in proximity to the X-ray source and movably in a direction of the axis of rotation of the object and a direction perpendicular to the rotation axis. The electrical signal from the photo-electric converter is processed to a cross-sectional image.
