  • Publication number: 20220412728
    Abstract: A bead appearance inspection device includes an input unit configured to enter input data related to a welding bead of a workpiece produced by welding, and a determination unit configured to perform an inspection determination related to a shape of the welding bead based on the input data. The determination unit determines which of a range of a value indicating a non-defective product zone, a range of a value indicating a gray zone, and a range of a value indicating a defective product zone a value obtained from the input data belongs to. The range of the value indicating the gray zone is between the range of the value indicating the non-defective product zone and the range of the value indicating the defective product zone.

  • Patent number: 8144088
    Abstract: A surface lighting device has one single light source and a light-guide-board. The board includes a light-guiding-section and a light-emitting-section. A shorter side of the light-guiding-section is not more than 8 mm, and an area of the light-emitting-section is not less than 500 mm2. The light-emitting-section has the following features: (1) a ratio of min. luminance vs. max. luminance of is not less than 0.3; (2) an average luminance ranges from 1 cd/m2 to 200 cd/m2, and (3) a change value in luminance per unit length is not more than (average luminance)×100 cd/m3. Employing plural light-emitting-elements in the light source allows the lighting device to produce versatile colors. The light source, light-guide-board and a holder are structured and shaped in optimum way, so that unevenness in luminance of the device is reduced. An LCD unit incorporating this surface lighting device increases its display quality, and a portable terminal incorporating this LCD unit produces easy-to-lead display.

  • Patent number: 7531631
    Abstract: The present invention herein discloses a method for purifying human serum albumin, which is characterized in that it comprises the steps of heat-treating a human serum albumin-containing solution including impurities originated from a host cell, in the presence of a divalent cation such as calcium ion, magnesium ion, nickel ion, cobalt ion, iron ion and zinc ion to thus selectively allow the impurities to undergo agglutination. The present invention also provides the highly purified human serum albumin prepared by the foregoing method.
