Patent number: 6092937Abstract: The inventive dispenser mechanism uniformly develops a photosensitive layer on a substrate. The mechanism uses a developer head that moves in a substantially linear relative motion with respect to the substrate and dispenses a developer at a controlled rate.

Contact of the rinse material with the developer material on the photosensitive layer retards the chemical reaction of developing. The rinse head waits for a predetermined dwell period after the developer head has dispensed the developer material before dispensing the rinse material. The mechanism may also use a suction head that has the same motion and velocity and removes loose material on a surface of the substrate.Type: GrantFiled: January 8, 1999Date of Patent: July 25, 2000Assignee: FAStar, Ltd.Inventors: Ocie T.

Patent number: 6024501Abstract: The invention concerns a method for controlling the activity of a development composition which comprises, as a developing agent, an organometallic complex. The method includes measuring the variations in optical density difference of the composition that varies with the degree of oxidation of the organometallic complex. The method also makes it possible to regenerate the development composition by means of an electrolysis current. A device for controlling the activity of the development composition includes two light-emitting diodes of different wavelengths, the light beams of which pass through the development composition, and photodiodes to receive transmitted light.Type: GrantFiled: March 11, 1998Date of Patent: February 15, 2000Assignee: Eastman Kodak CompanyInventors: Claude G. Goumont, Gerard R. Sirand-Rey, Alain Andre Charret

Patent number: 6020949Abstract: An automatic correction method is used in connection with a device for correcting an image on a surface light source that can be reproduced with a high degree of quality on a print or a developed film by compensating for the effects of a lens system and the photosensitive material properties as well as the effects of the properties of the surface light source. Photographic printing paper is exposed to a calibration pattern and is transferred to the development section to be developed. Thus, the calibration pattern image is formed on the print paper. The density of each portion of the calibration pattern image on the print is measured in a density measurement section and stored in a memory device. A microprocessor reads the measured values out of a memory device and corrects the image data stored in a frame memory based on the measured values.Type: GrantFiled: September 22, 1997Date of Patent: February 1, 2000Assignee: Noritsu Koki Co., Ltd.Inventor: Jyunji Yamada

Patent number: 6012606Abstract: An apparatus for is disclosed for detecting low liquid level in a bottom-draining container (12), the apparatus including a spout (14, 48) extended outwardly from the container, the spout having a central bore (18) through which liquid can drain from a bottom of the container; at least one guide member (26, 56, 62) positioned in the spout; at least one float (38) mounted for movement in the spout along the guide member, the float being buoyant in a liquid to be drained from the container; a source (42) for directing a beam of radiation into the spout along a path intersected by the float when a liquid drains to a preselected level within the spout; and a device (44, 46) for detecting when the float intersects the beam. The guide member may be omitted in one embodiment.Type: GrantFiled: June 27, 1996Date of Patent: January 11, 2000Assignee: Eastman Kodak CompanyInventors: Clark Eugene Harris, Dennis Robert Stell

Patent number: 5980126Abstract: In an automatic film developer, measurements are taken of internal temperature parameters during a warm up phase. Based on measured temperature values a time for completing the warm up phase is calculated. The calculated time for warm up is displayed so that it can be read by an operator. When the calculated time for warm up completion has elapsed, an indication is displayed that the film developer is operational. During the warm up phase, film is not allowed to advance through the automatic film developer. When the calculated time for warm up completion has elapsed, advance of film through the film developer is automatically started.Type: GrantFiled: March 25, 1997Date of Patent: November 9, 1999Assignee: Fuji Photo Film Co., Ltd.Inventors: Kenro Yamamoto, Seiichi Yoshizawa, Ryoei Nozawa, Akira Sugiyama

Patent number: 5968719Abstract: A photo filmstrip includes two side portions extending in a longitudinal direction, and has a leader, a trailer, and a series of effective frame regions arranged between the leader and the trailer. A series of bar codes are recorded on one of the side portions optically in a predetermined exposing condition, i.e., with light of an intensity suitable for the film speed. The bar codes are associated with the series of the effective frame regions. A test dot is recorded optically in the predetermined exposing condition, disposed in each of the leader and the trailer, for inspection of the optical recording.Type: GrantFiled: December 14, 1998Date of Patent: October 19, 1999Assignee: Fuji Photo Film Co., Ltd.Inventor: Yoshihiko Nakamura
