Patent number: 5850281Abstract: A photographic copier has a station which serves as a scanning station and a copying station. The station includes a support for an image to be scanned and copied, and a single light source for scanning and copying. A light-diffusing member is disposed between the light source and the support, and the light-diffusing member has a first condition for copying and a second condition for scanning. Light undergoes a high degree of diffusion in the first condition and a lower degree of, or substantially no, diffusion in the second condition.Type: GrantFiled: May 26, 1995Date of Patent: December 15, 1998Assignee: AGFA-Gevaert AG --FototechnikInventor: Gerhard Benker

Patent number: 5825466Abstract: A photographic printer for making 3D pictures or animation pictures from at least two 2D images on lenticular print material. The printer uses a monitor for sequentially displaying 2D images. A projection lens is used to project the displayed 2D images onto the print material. A tilting mechanism is used to tilt the print material for changing the projection angles. In order to correct for the distortion of images projected on the print material due to tilting, the 2D images are geometrically transformed according to the tilting angles. The same printer can be used to make 2D prints on regular photographic paper. The printer can be equipped with a plurality of projection lenses with different focal lengths so that pictures of different magnification factors can be made.Type: GrantFiled: January 18, 1996Date of Patent: October 20, 1998Assignee: Image Technology International, Inc.Inventors: Allen Kwok Wah Lo, Kenneth Quochuy Lao

Patent number: 5790237Abstract: A cleaning structure for an out-of-liquid conveying portion whose object is to facilitate detachment and attachment of a cleaning nozzle unit from and to a crossover rack, and to hold cleaning nozzles in predetermined positions suitable for the out-of-liquid conveying portion in a state in which the cleaning nozzle unit has been mounted to the crossover rack. In order to mount the cleaning nozzle unit to the crossover rack, the cleaning nozzles are made to penetrate through through-holes defined in one of side walls of the crossover rack. In this state, an interlocking member is elastically flexed so as to be inserted into an interlocking hole. After completion of its insertion of the interlocking member, a hook is brought into engagement with an upper edge of the interlocking hole by elastic recovery of the interlocking member. As a result, a case can be mounted to the side wall.Type: GrantFiled: May 15, 1996Date of Patent: August 4, 1998Assignee: Fuji Photo Film Co., Ltd.Inventors: Kouki Nomura, Hiroyuki Satoh

Patent number: 5767947Abstract: A method and apparatus for the production of individual prints and index prints from films which contain recorded data regarding the circumstances surrounding the exposure of the individual pictures stored on the film. Recorded data on the film is read, the data being associated with an individual picture and concerning a desired print format for the individual picture. The recorded data is preferably stored magnetically, but may also be stored optically. The system produces an individual print of the individual picture having a format based on the read data. The system also identifies, by modification of an image of the individual picture formed on the index print, the region of the film printed on the individual print and of the regions not printed, based on the read data.Type: GrantFiled: October 25, 1996Date of Patent: June 16, 1998Assignee: Agfa Gevaert AktiengesellschaftInventors: Hans-Georg Schindler, Hans-Juergen Rauh, Lothar Prause

Patent number: 5663783Abstract: In a stage-drive controlling device used in a scanning projection exposure apparatus, a targeted speed Iwy is imparted to a speed control system for controlling the speed of a substrate stage, and a targeted speed Irc is concurrently imparted to a speed control system for controlling the speed of a mask stage such that the two stages assume a predetermined positional relationship. A deviation Xrc in the speed of the Speed control system is multiplied by 1/4 (multiplied by the magnification of projection) by a deviation feedback system, and the multiplied value is fed back as a targeted input to the speed control system. For this reason, the following formula holds: Ywy={Kwy/(s+Kwy)}.times.(Yrc/4). If the response of the speed control system side (substrate stage side) is good, even if the speed response of the speed control system side (mask stage side) is poor, the speed ratio between the two stages is kept at 4:1.Type: GrantFiled: March 25, 1996Date of Patent: September 2, 1997Assignee: Nikon CorporationInventor: Toshio Ueda

Patent number: 5652645Abstract: A projection imaging system is described for patterning large, flexible substrates at high exposure speeds and desired resolution, the substrates being in the form of a continuous band fed from a roller for cost-effective electronic module manufacturing. From the continuous band, segments of one panel size are sequentially exposed one at a time. The segment being exposed is held rigidly on a scanning stage, on which is also mounted a mask containing the pattern to be formed on the substrate. The imaging subsystem is stationary and situated above the scanning stage. The mask is illuminated with a hexagonal illumination beam and a region of similar shape is imaged on the substrate. The stage is programmed to scan the mask and substrate simultaneously across the hexagonal regions so as to pattern one whole panel.Type: GrantFiled: July 24, 1995Date of Patent: July 29, 1997Assignee: Anvik CorporationInventor: Kanti Jain

Patent number: 5650840Abstract: A method of detecting a focus position of a projection optical system at a high throughput and with high accuracy. A sensor pattern (SP) which is provided on a wafer stage (WS) as a light-receiving part of a photoelectric sensor (PES) is moved in the direction of an optical axis (AX) of a projection optical system (PL), and at the same time, it is moved in a direction (X) perpendicular to the optical axis (AX). While doing so, a reticle pattern (RP) which is provided on a reticle (R) is illuminated by illuminating light (IL) for exposure, and an image of the reticle pattern (RP) is formed on the sensor pattern (SP) through the projection optical system (PL). Light passing through the sensor pattern (SP) is received by the photoelectric sensor (PES), and a focus position is detected on the basis of the intensity of the transmitted light.Type: GrantFiled: September 12, 1995Date of Patent: July 22, 1997Assignee: Nikon CorporationInventor: Tetsuo Taniguchi

Patent number: 5644381Abstract: By the method of exposure using attenuation type phase shift mask, based on the phase angle of exposure light passing through second and third light transmitting portions and on hole diameters of the second and third light transmitting portions, an optimal value between first and second distances h.sub.1 and h.sub.2 can be calculated. Therefore, a resist film can be exposed at optimal focal position. As a result, even when there is a step in the material to be exposed, a desired pattern can be exposed with high precision through the same steps in every region of the material to be exposed.Type: GrantFiled: May 15, 1995Date of Patent: July 1, 1997Assignee: Mitsubishi Denki Kabushiki KaishaInventors: Junji Miyazaki, Nobuyuki Yoshioka

Patent number: 5642184Abstract: Apparatus and method for contact printing uses a vacuum contact plate and a screen frame to hold a master film sheet in contact registration with a screen having a region that is substantially porous to the passage of air disposed about a central photosensitive region. The vacuum contact plate receives the screen frame and supports the master film sheet and the screen on an elevated, substantially planar component. Air is evacuated from a hollow cavity within the elevated component to create a pressure differential across the master film sheet to urge the master film sheet in contact with the screen. If the master film sheet is not large enough to cover the entire porous region of the screen, the master film sheet is attached to a carrier sheet of sufficient size. The carrier sheet is then placed on the elevated component to be retained in contact registration with the photosensitive screen.Type: GrantFiled: October 24, 1995Date of Patent: June 24, 1997Inventor: Ernest Ohlig
