Abstract: Provided are a processing method and a processing apparatus in which a concentration of a solid content of a development fatigue liquid is low and a moisture content of a discharged solid substance is small. The processing method is a method for removing a first solid substance having a smaller specific gravity than the washout liquid and a second solid substance having a larger specific gravity than the washout liquid from a development fatigue liquid including a solid substance generated by removal of a non-exposed portion of a photosensitive resin plate that has been exposed in an image shape by development using the washout liquid.

Abstract: A coating device and a coating method are provided. The coating device comprises a coating station for coating a coating liquid on a band-shaped substrate running continuously, and a coat-adjusting station disposed downstream of the coating station for adjusting the coating liquid on the substrate so that the coating liquid layer is coated on the substrate at a predetermined thickness. The coating station and the coat-adjusting station comprise first and second bars for respectively coating and measuring the liquid agent. The coating liquid can be coated on evenly and in a stable manner even if the coating operation is performed with the substrate running at a high speed.

Abstract: An apparatus for anodizing a support for a lithographic printing plate which comprises a backing roller which guides a web made of aluminum or an alloy thereof in a state of contacting the backing roller, (an) electrode(s) which is/are arranged along the peripheral surface of the backing roller in a concentric arc, an electric supplier which is provided at least on the upstream side or the downstream side of the backing roller, and an electrolyte solution which fills the clearance between the backing roller and the electrode, and an anodizing method using the same. By using the apparatus, the electric voltage loss can be reduced in electrolyte solution, and only a single surface of the supports is anodized without the necessity for providing any special means. Anodizing can be conducted at a high speed and the thickness of anodized layer easily increased. Moreover, thin supports can be anodized without fusion troubles.

Abstract: An apparatus for continuous electrolytic treatment of an article of aluminum web or an aluminum alloy including an electrolytic part, a pre-stage power supply part provided upstream of the electrolytic part, a post-stage power supply provided, downstream of the electrolytic part and a power source, at least one electrode in the pre-stage power supply part and at least one electrode in the post-stage power supply part part being connected with one pole of the power source, and at least one electrode of the electrolytic part being connected with the other pole of the power source. This apparatus can decrease a running cost such as the electric cost and the cooling cost as well as the facilities cost, can conduct a high speed treatment and increase the thickness of a film without fusing an aluminum article, even if the aluminum article has a small sectional area, such as a wire, a foil or a thin web.

Abstract: An electrolytic treatment apparatus for continuously electrolyzing an elongated product of aluminum or an aluminum alloy at a low electrolyzing voltage and reduced amount of electric power. The apparatus includes at least one electrolytic section and front- and rear-side power supply section disposed respectively at front and rear sides of the electrolytic section in the longitudinal direction of the elongated product in the electrolytic section. Each of the power supply sections contains at least one electrode, and the electrolytic section contains a plurality of electrodes. The electrolytic section and the power supply sections are filled with an electrolyte in which the elongated product and the electrodes is immersed.

Abstract: A method for manufacturing a substrate for presensitized plates for use in making lithographic printing plates comprises the steps of electrolytically surface-roughening an aluminum plate or an aluminum alloy plate in a nitric acid-containing electrolyte and then etching the surface with an alkali or an acid to thus form irregularity in the order of not more than 0.1 .mu.m within pits formed on the surface during the electrolytic surface roughening treatment. The method makes it possible to provide a lithographic printing plate stably and simultaneously having excellent printing durability and good resistance to background contamination of non-image areas.

Abstract: An electrolytic treatment apparatus is provided in which one or more electrolyte discharge outlets and one or more electrolyte supply inlets are provided between main counter electrodes so that the concentration and temperature of the electrolytic treatment solution at the the inlets and at the outlets can be made close to one another. As a result, uniformity and fineness in grains can be maintained, electrolysis efficiency can be raised, and the production speed can be improved.

Abstract: A coating method and apparatus in which a freely falling film of a coating solution is applied to a web moving along a continuously rotating backing roll. The film width is wider than that of the web. The coating solution is removed from the backing roll by a cleansing device such as one that applies a solvent to the backing roll and then suctions the solvent and coating solution from the backing roll.

Abstract: A multi-layer coating method in which a first layer is first applied to a moving web and is allowed to partially dry before a second layer is applied as a freely falling coating composition film.

Abstract: A method for making multilayer coating on a support, which comprises simultaneously applying multiple layers of at least two nonaqueous coating liquids on the support, at least one of the liquids containing an electron radiation curable compound, irradiating the applied layers with electron rays at a rate of 50 Mrad/sec. or less to cure them or to increase the viscosity thereof, and then drying. This method can be applied to the production of presensitized plates, multilayer photographic materials, multilayer analytical elements, etc.
