Patent number: 8654333Abstract: A surface inspection apparatus includes a light source for applying a detection laser beam to a film sample. A light receiver has plural photomultiplier tubes arranged in a width direction of the film sample, for receiving output light reflected by the film sample. A defect detector detects a defect on the film sample according to an output signal output by each of the photomultiplier tubes. A sensitivity corrector sets sensitivity of the photomultiplier tubes to process an output of the light receiver for output noise suppression. Specifically, the sensitivity corrector determines a set sensitivity of the photomultiplier tubes by correcting a sensitivity characteristic thereof for abnormality detection, to keep a sensitivity difference between the photomultiplier tubes as small as a predetermined value or less. Furthermore, plural light valves upstream from the light receivers are controlled by the sensitivity corrector for their transmittance.Type: GrantFiled: March 24, 2011Date of Patent: February 18, 2014Assignee: Fujifilm CorporationInventors: Bungo Shigeta, Ippei Takahashi

Patent number: 6375008Abstract: A light-shielding packaging for a roll of continuous photosensitive web wound on a core having on its each end a light-shielding flange disc has at its leading end a heat-shrinkable light-shielding leader sheet having a thickness of 30 to 200 &mgr;m which shows a heat shrinkage ratio at 50° C. of lower than 1% both in the longitudinal and width directions and a heat shrinkage ratio at 100° C. in the range of 5% to 30% in the longitudinal direction and a heat shrinkage ratio at 100° C. of less than the heat shrinkage ratio in the longitudinal direction by 1% or more in the width direction. The leader sheet has a length larger than the length of the outermost convolution of the roll and a width larger than the distance between the outer face of one flange disc and the outer face of another flange disc, and each side portion of the leader sheet is light-tightly attached by heat shrinkage to the outer face of the flange disc at least at a portion adjacent to the periphery of the flange disc.Type: GrantFiled: December 26, 2000Date of Patent: April 23, 2002Assignee: Fuji Photo Film Co., Ltd.Inventors: Bungo Shigeta, Hirofumi Abe, Yasuhiko Kitamura, Yoshio Hara, Masafumi Fukugawa, Akihisa Inoue, Norihiro Kadota, Koichi Nakatogawa

Patent number: 6340042Abstract: An elongate light-shield film is withdrawn for a length corresponding to the width of a photosensitive film by a light-shield film supply mechanism, cut off into a light-shield film by a first cutting mechanism, and fed to an overlapping position by a feeding and positioning mechanism. In the overlapping position, a transverse end of the light-shield film is caused to overlap a longitudinal end of the photosensitive film, and the overlapping ends are cut off by a second cutting mechanism. Abutting ends of the light-shield film and the photosensitive film are then joined to each other by a tape, and the light-shield film and the photosensitive film which are thus joined are around on a spool. Debris produced when the overlapping ends are cut off is automatically discharged.Type: GrantFiled: August 29, 2000Date of Patent: January 22, 2002Assignee: Fuji Photo Film Co., Ltd.Inventors: Bungo Shigeta, Akihisa Inoue, Akinori Takase
