摘要:
A heating method and apparatus for a band-shaped body transported in a constant conveying direction in a heating zone so as to heat the band-shaped body is provided. The method includes detecting whether a portion of the band-shaped body at which width and/or thickness changes is passing through the heating zone setting a first supplied heat quantity, and supplying heat with the first supplied quantity to the band-shaped body in the heating zone; and setting a second supplied heat quantity, and supplying heat with the second supplied quantity to the band-shaped body in the heating zone. The method also includes increasing or decreasing at least one of air flow rate or temperature of the heated air stream. The apparatus includes an air flow ratio changing unit which maintains a constant sum of introduced air stream flow rate and bypass air stream flow rate.

A method for manufacturing a lithographic printing plate is provided in which conditions for heating a support and a photosensitive coated layer in a drying and heating step can be changed rapidly over a wide range, and the photosensitive coated layer and the support are heated without being contacted.
摘要:
In a method of producing a photosensitive planographic printing plate according to the present invention, a web is coated with a coating solution, and a coating solution film thus formed is rapidly dried. For this drying, fresh air is blown onto the web W heated with a heat roll such that the air is blown parallel to the coating solution film. The coating solution film can thereby be prevented from changing its thickness due to an air stream during drying, while the coating solution film can be rapidly dried. Accordingly, the coating solution film can be dried before the film is leveled, to form a coating layer having uniform thickness.
摘要:
A photosensitive planographic printing plate which can avoid quality defects such as residue films and the like and improve yield, and a fabrication process thereof. A coating layer of a region corresponding to an edge portion of a PS plate is preparatorily cleared by coating removal. Hence, pressure fogging which is formed by pressure at a time of cutting of a web will not occur.

Disclosed are a positive type lead-frame forming material which contains a light-sensitive material comprising an o-quinonediazide compound and a novolak resin, and a positive type lead-frame forming material which contains a positive resist composition comprising (1) a water-insoluble but alkaline water-soluble resin, (2) a compound capable of generating an acid by irradiation with active rays or radiant rays, and (3) a compound containing a group decomposable by acid which can increase its solubility in an alkaline developer through the action of the acid.
摘要:
The NOx-cleaning paving structure of the present invention comprises a concrete base layer 1, a paving layer 2 and a surface layer 3 as illustrated in FIG. 1. The surface layer 3 comprises 100 parts by weight of cement, 5-50 parts by weight of titanium oxide powder and 100-700 parts by weight of aggregate, by which the surface layer on the paving layer can be provided with an NOx-cleaning action and an excellent durability. In addition, pozzolan materials, particularly a blast furnace slag, or adsorbing materials can be added to the surface layer. The paving layer 2 comprises an asphalt paving 21 or a concrete paving 6, both of which may include the used paving layers. It is preferable that the asphalt paving is porous and the surface thereof has an unevenness. Additionally, it is preferable that the thickness of the surface layer is 1-300 mm for the concrete paving and 2-15 mm for the asphalt paving. Among cement, injection cement for half-flexible paving is preferable.
