And Photographic Medium Support Means Patents (Class 396/628)
  • Patent number: 8303197
    Abstract: In an apparatus for performing a substrate developing process, a first washing tank and a second washing tank are disposed on both sides of a substrate support section for supporting the substrate opposite to each other to wash a developing nozzle. The developing nozzle moves in a horizontal direction from the first washing tank toward the second washing tank and supplies a developing solution onto the substrate in the meantime. After supplying the developing solution, the developing nozzle is received in the second washing tank, and the developing solution adhered to the developing nozzle is removed by a washing solution in the second washing tank.

  • Patent number: 7171974
    Abstract: At least one of a nucleus forming process, a nucleus growing process, a chemical sensitizing process, and a spectral sensitizing process for producing a silver halide photographic emulsion is performed by using a microreactor. A minute region of the microreactor is used to precisely perform a reaction of nucleus formation. A condition under which host grains are allowed to react with newly supplied silver halide nuclei is made uniform to cause uniform crystal growth. A predetermined quantity of molecules for chemical sensitization is doped in a crystal lattice of a nucleus of silver halide to effect a sensitizing process. Alternatively, a spectral sensitizing process in which a single molecular layer of a spectral sensitizer is uniformly adsorbed on a silver halide nucleus grain surface is securely carried out.

  • Patent number: 6300034
    Abstract: An apparatus is provided for processing an imaged element comprising a support, an image-receiving layer and a silver halide emulsion layer. The apparatus comprises a tank for holding a processing liquid, driving means for propelling the imaged element through the tank, guide means for directing the path of the imaged element through the tank and developer circulation means for promoting circulation of the processing liquid in the tank. The circulation means includes flow control means to provide substantially fresh processing liquid to the surface of the imaged element and to disperse exhausted processing liquid present at the surface of the element, thereby eliminating the difficulties associated with local developer exhaustion and ensuring that consistently high image quality is maintained across the whole area of the imaged element.

  • Patent number: 6228557
    Abstract: An apparatus is provided for processing a lithographic printing plate precursor comprising an aluminium support, an image-receiving layer and a silver halide emulsion layer. The apparatus comprises a tank for holding a processing liquid, at least one set of driving rollers, at least one guide roller or guide plate and means for providing direct electrical contact between the lithographic printing plate precursor and other electrically conducting surfaces in the apparatus which are in contact with the processing liquid. A method of processing a lithographic printing plate precursor using the apparatus is also disclosed. Undesirable electrochemical cell formation during processing, and the consequent deleterious effects on silver image formation, are prevented and subsequent problems with poor plate run length can therefore be avoided.
