  • Publication number: 20030043361
    Abstract: An object of the invention is to prevent leakage of powder, etc. by effectively sealing en end of a rotary body with a simple structure. An end seal which prevents toner leakage by contacting an outer circumference of a developing roller, has a contact portion made of a sealing material of yarns including porous hollow fibers. Being made of hollow fiber, the seal exhibits reduced repulsive elasticity during compression, and high hermeticity is attained in the yarns by applying only a relatively light load to such an extent that deformation in a pressure-applying supporting plate and the to-be-pressed developing roller is not caused, thereby maintaining sealability. The seal is freely deformable so as for a stepped portion to be sealed effectively. By mixing non-hollow fibers, the seal can be partially provided with elasticity. By mixing electrically conductive fibers, the seal can be used in a region where static protection is necessitated.

  • Patent number: 4996560
    Abstract: 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.

  • Patent number: 4980262
    Abstract: 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.
