Patent number: 5518844Abstract: In a first processing step, whether a first photosensitive material is a particular photosensitive material is detected. If it is detected at least that the first photosensitive material is the particular photosensitive material, processing conditions in the first processing step are recorded in a predetermined position on the first photosensitive material. Exposure conditions in the exposure step are set in accordance with one of the result of the detection and the processing conditions recorded on the first photosensitive material. The second photosensitive material is exposed under the set exposure conditions. If the first photosensitive material is detected to be a particular photosensitive material, the setting of the exposure conditions is changed in the exposure step, and the exposure conditions are set in such a manner as to compensate the difference in the characteristic occurring in the image of the particular first photosensitive material depending on standard processing and particular processing.Type: GrantFiled: October 5, 1994Date of Patent: May 21, 1996Assignee: Fuji Photo Film Co., Ltd.Inventors: Nobuo Matsumoto, Toshihiro Nishikawa

Patent number: 5496687Abstract: A photographic film-incorporated camera which comprises a supply room in which an unexposed photographic film drawn from a cylindrical cartridge has been wound up and a wind-up room with which the cylindrical cartridge is enclosed, and which is designed to feed one exposure of the photographic film drawn from the supply room per a shooting to wind up in the cylindrical cartridge. The photographic film comprises a photographic layer on a composite of a support and a subbing layer. The composite is obtained by subjecting the support which comprises an aromatic polyester having a glass transition temperature of 50.degree. to 200.degree. C. to heat treatment at a temperature of 40.degree. C. to the glass transition temperature for 0.1 to 1,500 hours before or after forming the subbing layer on the support.Type: GrantFiled: March 2, 1995Date of Patent: March 5, 1996Assignee: Fuji Photo Film Co., Ltd.Inventor: Fumio Kawamoto

Patent number: 5466560Abstract: This invention relates to cameras designed for single or limited use. It more particularly relates to cameras that are intended for one use, after which they are recycled, subsequent to removal of the film for development and printing or scanning. The camera and film combinations provide exceptionally sharp images.Type: GrantFiled: October 13, 1993Date of Patent: November 14, 1995Assignee: Eastman Kodak CompanyInventors: Allan F. Sowinski, Richard P. Szajewski, James P. Merrill

Patent number: 5466561Abstract: The invention relates to an image plate (1) for intra-oral dental X-ray photography, the plate being placed in a shield (3) enveloping it for the duration of photography. According to the invention the shield has been made pervious to X-rays but impervious to visible light, and it comprises a closed shielding bag of plastic membrane. The shield may be made up of an inner shielding bag (3) impervious to light and a surrounding closed outer shielding bag which may be of transparent plastic membrane. After photography, the possible outer bag is first removed, the patient's saliva being removed along with it. Thereafter the image plate (1) and the surrounding shielding bag (3), one end (6) of which has been opened or, if an outer bag is used, is possibly already open, are introduced into the read-out apparatus, in which a pulling device grips the end of the plate in the bag, whereafter the bag can be pulled out while the plate remains in the read-out apparatus for the reading out of the image.Type: GrantFiled: September 2, 1994Date of Patent: November 14, 1995Assignee: Orion-Yhtyma OyInventor: Matti Rantanen

Patent number: 5397686Abstract: A method for temporarily marking a surface whose distance from a light beam source can substantially vary, without requiring focusing or refocusing of the light beam, commences with the step of coating a portion of the surface with a light reactant, color-forming chemical solution. The solution is soluble in a liquid solvent that is nonreactive with the surface. The coated portion of the surface is exposed to a collimated, non-focused laser beam exhibiting an airy disk pattern having central bright spot, the exposure occurring for a period of time that enables the central bright spot to expose the coating and to manifest a color change at points of incidence. The bright spot exhibits a diameter that does not exceed a predetermined diameter within an expected distance variations between the source of the laser beam and the surface.Type: GrantFiled: March 22, 1993Date of Patent: March 14, 1995Assignee: Northrop Grumman CorporationInventors: Glenn E.

Patent number: 5395736Abstract: Acid can be generated by exposing a superacid precursor to actinic radiation effective to generate superacid from the superacid precursor and heating the superacid in admixture with a secondary acid generator capable of undergoing thermal decomposition to produce a secondary acid. The superacid catalyzes decomposition of the secondary acid generator, thus increasing the quantity of strong acid present in the medium. The resultant secondary acid can be used to effect a color change in an acid-sensitive material, so providing an imaging process.Type: GrantFiled: October 22, 1993Date of Patent: March 7, 1995Assignee: Polaroid CorporationInventors: Jurgen M.
