Publication number: 20080136893Abstract: When laser beams with a wavelength of 9.3 ?m or 9.6 ?m are used, a pulse width t (?sec) which is a radiation time of the laser beam and an energy density E (kw/cm2) of the laser beam on an X-ray film are set such that they meet requirements based on an area A between line segments A1 and A2. Moreover, when laser beams with a wavelength of a 10-micrometer band, such as 10.6 ?m, is used, the pulse width and the energy density are set such that they meet requirements based on an area B between line segments B1 and B2. As a result, since the pulse width t is within a range of equal to or larger than 3 ?sec and smaller than 30 ?sec, a high-quality marking pattern with excellent visibility can be formed while improving the productivity of the X-ray film.Type: ApplicationFiled: November 26, 2007Publication date: June 12, 2008Applicant: FUJIFILM CORPORATIONInventors: Keisuke Endo, Hiroyuki Nishida

Patent number: 7369152Abstract: In a marking device, by illuminating a laser beam onto an X-ray film which is a light-photosensitive heat-developing photosensitive material, an inner portion of a surface layer is melted, a cavity is formed, and a dot, which projects a surface out in a convex shape, is formed. At this time, an illumination time of the laser beam is controlled in order to control melting of the surface layer. In the marking device, when conveying of an X-ray film is stopped, oscillation of a laser oscillating tube is continued until a predetermined period of time elapses. When stoppage is for a short time, control is carried out such that marking can be started quickly.Type: GrantFiled: March 16, 2005Date of Patent: May 6, 2008Assignee: Fujifilm CorporationInventors: Keisuke Endo, Hiroyuki Nishida

Patent number: 7360348Abstract: A sorting and conveying line provided at an X-ray film cutting and collection operation includes a defective sheet gate, a collection gate and a sample gate for sorting X-ray film sheets, which have been cut to a predetermined size at a cutting section, while the X-ray film sheets are conveyed. Film detection sensors are disposed at entrance and exit sides of each of the defective sheet gate, the collection gate and the sample gate, and each film detection sensor detects the X-ray film sheet at times when the X-ray film sheet should be conveyed and sorted. Based on the results of detection, a determination is made as to whether or not there is any failure in control on a number of produced X-ray film sheets, and the like, as well as conveyance and sorting operations. This allows smooth and quick handling in the event of a failure.Type: GrantFiled: December 3, 2003Date of Patent: April 22, 2008Assignee: Fujifilm CorporationInventors: Yoshiyuki Ishii, Hiroyuki Nishida

Patent number: 6927408Abstract: When a film is rewound, light is applied from light-emitting units to the film, and light that has passed through the film is detected by light-detecting units to detect a plurality of inclined defects in the film based on a change in the intensity of the light transmitted through the film. Slits oriented in the direction of the inclined defects are disposed in front of the light-emitting units and the light-detecting units. Detected signals outputted from the light-detecting units are transmitted to a processing device and processed thereby. The processing device processes the signals by approximating a maximum value array of extremal values of the signals in respective reference lengths of the film, with two functions in zones, and identifying a boundary between the zones as a position where a defect disappears.Type: GrantFiled: June 21, 2002Date of Patent: August 9, 2005Assignee: Fuji Photo Film Co., Ltd.Inventors: Kazuo Onishi, Hiroyuki Nishida

Patent number: 6908728Abstract: By irradiating a laser beam onto an X-ray film that includes a support layer having disposed thereon an emulsion layer, the emulsion layer is melted, numerous minute air bubbles are generated in the emulsion layer, and the emulsion layer becomes convex, whereby a visible dot pattern is formed. The irradiation time and wavelength of the laser beam are selected so that separation is not generated between the support layer and the emulsion layer. By defocusing and irradiating the laser beam, the X-ray film may substantially uniformly receives energy of the laser beam. Moreover, an undersurface layer may also be formed, and the laser beam may be irradiated onto the undersurface layer to form a dot pattern on the undersurface layer. A device and a method for forming a marking pattern representing identification information on a rolled photosensitive material and cutting the photosensitive material into sheets are disclosed.Type: GrantFiled: April 15, 2003Date of Patent: June 21, 2005Assignee: Fuji Photo Film Co., Ltd.Inventors: Keisuke Endo, Hiroyuki Nishida
