Patent number: 6685367Abstract: In the processing of thermal films, following processing, negatives are scanned and the resulting image files are digitally manipulated to render a desired output. Since it is desirable to return thermally processed films to a control location for silver recovery, the negatives are not returned to the consumer. In the method and apparatus of the present invention, after processing and scanning, the film or negative can be rendered unscannable by heating it to a temperature that develops the entire film to its maximum density and destroys the images on the film. As a further option, the film can be physically destroyed by use of for example, a shredder or illuminator downstream of the scanner.Type: GrantFiled: June 13, 2000Date of Patent: February 3, 2004Assignee: Eastman Kodak CompanyInventors: James H.

Publication number: 20020058207Abstract: A method for forming a positive image, which comprises exposing an image-forming material comprising a substrate and a positive photosensitive composition layer containing a novolak resin and a photo-thermal conversion material which absorbs light from an image exposure light source and converts it to heat and not containing a thermally decomposable material which decomposes by the action of heat generated by the photo-thermal conversion material upon absorption of light from the image exposure light source, formed on the substrate, followed by development with an alkali developer containing an amphoteric surfactant to form a positive image.Type: ApplicationFiled: January 19, 1999Publication date: May 16, 2002Inventors: TOSHIYUKI URANO, ETSUKO HINO, MITSURU SASAKI

Patent number: 6335147Abstract: There is disclosed a developing processing method and apparatus in which developing processing is carried out with a developing solution being jetted toward an emulsion surface of a photosensitive material from jetting holes of a blowoff chamber. Only one blowoff chamber is disposed in a developing tank and conveying roller sets are disposed at both sides of the blowoff chamber. The photosensitive material is horizontally conveyed above the blowoff chamber by the conveying roller sets. Due to the number of components of the developing processing tank being thus reduced, the apparatus can be made small in size. Positions where the photosensitive material is nipped by the roller sets are located within a processing solution, and therefore, there is no possibility of the photosensitive material being nipped and conveyed in a state in which outer peripheral surfaces of the rollers are wet non-uniformly with the processing solution. As a result, non-uniform processing is prevented.Type: GrantFiled: December 28, 1999Date of Patent: January 1, 2002Assignee: Fuji Photo Film Co., Ltd.Inventors: Hideaki Nomura, Hideo Iwasaki

Patent number: 6333144Abstract: In a developing processing method and apparatus in which developing processing is carried out in such a manner that a processing solution is jetted from jetting holes to an emulsion surface of a photosensitive material, a hole diameter of the jetting holes is set to be 0.5 mm to 0.9 mm. In this case, clogging of the jetting holes does not easily occur and the processing solution can be jetted from the jetting holes stably for a long period of time. Accordingly, non-uniform processing is rarely caused. Intervals between the jetting holes in the transverse direction of the photosensitive material are each in a range of 3.0 mm to 4.5 mm. The jetting holes are disposed in such a manner that jetting holes of adjacent three rows in a direction in which the photosensitive material is conveyed are located at different positions to form a staggered arrangement, and the three rows of jetting holes are formed repeatedly.Type: GrantFiled: December 28, 1999Date of Patent: December 25, 2001Assignee: Fuji Photo Film Co., Ltd.Inventors: Hideaki Nomura, Kazuo Sanada
