Patent number: 8202365Abstract: In a process for producing an oriented inorganic crystalline film, a non-monocrystalline film containing inorganic crystalline particles is formed on a substrate by a liquid phase technique using a raw-material solution which contains a raw material and an organic solvent, where the inorganic crystalline particles have a layered crystal structure and are contained in the raw material. Then, the non-monocrystalline film is crystallized by heating the non-monocrystalline film to a temperature equal to or higher than the crystallization temperature of the non-monocrystalline film so that part of the inorganic crystalline particles act as crystal nuclei.Type: GrantFiled: December 17, 2008Date of Patent: June 19, 2012Assignee: FUJIFILM CorporationInventors: Kenichi Umeda, Hiroyuki Hirai, Atsushi Tanaka, Katsuhiro Kohda, Kohei Higashi, Hiroshi Sunagawa

Publication number: 20100240164Abstract: A coating film is formed by applying, on a tentative support, a dispersion solution in which at least an inorganic semiconductor particle and a binder are dispersed. Then, a radiation photoconductive layer is formed by subjecting the coating film to thermal compression, and the radiation photoconductive layer is joined to an active matrix layer in which multiple switching elements are arranged.

Publication number: 20090032096Abstract: In a process for producing a thin-film device having an inorganic film formed over a resin-based substrate, a thermal-buffer layer is formed over a substrate which contains a resin material as a main component, and a light-cutting layer is formed over the thermal-buffer layer, where the light-cutting layer prevents damage from short-wavelength light to the substrate by reducing the proportion of the short-wavelength light which reaches the substrate. Thereafter, a non-monocrystalline film which is to be annealed is formed over the light-cutting layer, where the non-monocrystalline film transmits the short-wavelength light to such a degree that the short-wavelength light can damage the substrate. Then, an inorganic film is formed by irradiating the non-monocrystalline film with the short-wavelength light so as to anneal the non-monocrystalline film.Type: ApplicationFiled: July 30, 2008Publication date: February 5, 2009Applicant: FUJIFILM CorporationInventors: Atsushi TANAKA, Kenichi UMEDA, Kohei HIGASHI, Hiroshi SUNAGAWA, Katsuhiro KOHDA

Publication number: 20070184483Abstract: The biochemical analysis unit has a base plate and absorptive regions. The absorptive regions are surrounded by the base plate formed of materials which shield a radioactive ray and a light. In the absorptive regions are applied and absorbed specific binding substances to be bound with substances derived from a living organism that are labeled with labeling substances for generating the radioactive ray or the light. The base plate prevents the specific binding substances from penetrating in the other absorptive regions.

Patent number: 6806486Abstract: Stimulating rays produced by a line light source are linearly irradiated onto an area of a stimulable phosphor sheet, on which a radiation image has been stored, the stimulating rays causing the sheet to emit light in proportion to an amount of energy stored thereon during its exposure to radiation. Light emitted from the exposed linear area of the sheet is received with a line sensor comprising photoelectric conversion devices arrayed along each of a length direction of the linear area of the stimulable phosphor sheet and a direction normal to the length direction. The sheet is moved with respect to the line light source and the line sensor and in a direction different from the length direction of the linear area of the sheet. Operation processing is performed on outputs of the photoelectric conversion devices, which outputs have been obtained at respective positions of movement and correspond to an identical site on the sheet.Type: GrantFiled: June 21, 2001Date of Patent: October 19, 2004Assignee: Fuji Photo Film Co., Ltd.Inventors: Yuji Isoda, Sumihiro Nishihata, Satoshi Arakawa, Kenji Takahashi, Ichirou Miyagawa, Katsuhiro Kohda
