Patent number: 4996560Abstract: An apparatus for exposing of an image of an original film on photosensitive material, the film and the photosensitive material being held together by vacuum contact between a transparent plate and a flexible sheet. The apparatus includes a squeegee unit which moves while pressing the flexible sheet. The squeegee unit forcibly moves the air, thereby speeding up the setting of the vacuum contact. The apparatus also includes a speed changing unit for changing the speed of the squeegee unit depending on the resistance of the air to movement. If the air moves easily, the squeegee unit moves rapidly. If the air does not move easily, the squeegee unit moves slowly, or the squeegee unit stops for a prescribed period and then, after the air is removed, is restarted. Thus, complete removal of air is carried out rapidly.Type: GrantFiled: October 31, 1989Date of Patent: February 26, 1991Assignee: Dainippon Screen Mfg.

Patent number: 4980262Abstract: A photographic contact printing process is disclosed having application in the mass production of replicate video discs from a master disc, and other applications wherein it is desired to replicate micro-detail over a relatively large area. A problem with conventional contact printing from a mask to a photographic medium is one of maintaining intimate contact over a relatively large area since dust, dirt, etc., are almost impossible to completely eliminate in any practical manner. In accordance with the present invention, a contact printing process is provided wherein intimate contact is not necessary for making high quality contact prints. The present invention recognizes that in contact printing information from a master disc to a replicate disc, the contact printing process is significantly less sensitive to imperfect contact between the master disc and the replicate disc if one employs a replicate disc comprising a photosensitive material having a certain optical properties.Type: GrantFiled: August 29, 1979Date of Patent: December 25, 1990Assignee: Eastman Kodak CompanyInventors: Harold T. Thomas, Dennis G. Howe

Patent number: 4942426Abstract: An improvement in a contact printer which comprises means for supporting a film and an original in superposed relationship on a vacuum table, means for providing a source of light for exposing the film through the original, and means for moving the light over the surface of the superposed film and original. A substantially impervious, flexible and transparent cover sheet carried by the light moving means is arranged to cover the superposed film and original as the exposing light is scanned across the film and original whereby the vacuum is applied to the film and the original to remove air from therebetween as the film is exposed by the light through the cover sheet and the original. The improvement comprises means for contacting the surface of the cover sheet during use and removing dust and dirt thereon to assure that the optical path for the exposing light remains clear and unobstructed.Type: GrantFiled: November 17, 1989Date of Patent: July 17, 1990Assignee: Eastman Kodak CompanyInventors: Robert S.
