摘要： PROBLEM TO BE SOLVED: To provide a blanket for offset printing capable of suppressing a deterioration of the blanket itself to the minimum limit by simply removing a volatile component of an ink from the blanket and restarting a printing operation immediately after a treatment by shortening a stopping time of an offset printer for a recovering work. SOLUTION: The blanket comprises a blanket body having a base material part and a surface part. The base material part has a heating mechanism to be a self-temperature regulation type. A method for offset printing using the blanket comprises the steps of supplying an ink to an intaglio, scraping the excess ink by a doctor blade, then receiving a pattern on the intaglio by an ink placing surface of the blanket, transferring the received pattern to a matter to be printed, and offset printing the matter.

摘要： PROBLEM TO BE SOLVED: To prevent generation of a defect on a surface of a blanket by refuse or bubbles. SOLUTION: In the method for manufacturing a blanket used for offset printing comprising the step of forming a surface layer of a mirror state by crosslinking a material of the surface layer of the blanket while bringing the material into contact with its mirror surface, before bringing the material into contact with the mirror surface, the mirror surface is cleaned by coating it with a cleanser 2 by a head 4 of a coater. The mirror surface is a surface of a film-like material 1. Contacting with and crosslinking the mirror surface are conducted by coating the surface of the material 1 with a material of the surface layer by a head 5 and crosslinking it in a drying furnace 7.

摘要： PROBLEM TO BE SOLVED: To prevent ink from being wasted, simplifying an apparatus requiring no doctor ring process itself, and reduce cost by saving processes by providing an ink spouting part, spouting ink from the ink spouting part directly, and supplying and filling it in a recessed pattern. SOLUTION: The ink spouting part is furnished with an ink jet nozzle 3 for spouting ink. For example, ink 107 is spouted in the pattern 1 of a printing recessed part 105. By repeating spouting several times, ink is supplied having a filling quantity needed to a predetermined pattern volume. After that, ink leveling work is carried out. Subsequently, an ink pattern 4 is received by a blanket 113 to then be transferred on a glass substrate before obtaining a printed pattern. In this way, by performing ink supplying and filling operations directly, ink filling can be done completely, and printing pattern can also be transferred finely in the entire surface. In addition, an efficiency of use of ink is made 100%, thereby making a doctoring process itself unnecessary so that the cost can be reduced.

摘要： PURPOSE:To mold a lens without generating strain, by cooling the center part and surface part of a plastic lens molded by injection molding in a specific stage. CONSTITUTION:Cooling water is allowed to flow through cooling pipes 10A, 10B in order to cool molds 2A, 2B. When the flow rate of cooling water is controlled to 0.5l/min, the lens surface temp. and center temp. of a molded lens respectively become temp. curves P1, P2. The surface temp. of the lens is 300 deg.C at the finish point of time of injection (at the start time of cooling) but lowered to glass transition temp. of 160 deg.C as shown by the temp. curve P1 after 17.5 sec. The center temp. of the lens at this time is 289 deg.C and the temp. of the molds is 155 deg.C. As a result of further allowing cooling water to continuously flow at 20 deg.C, the surface temp. of the lens becomes 113.8 deg.C and the center temp. thereof becomes 130 deg.C and the temp of the mold becomes 113.1 deg.C after 90sec and the lens free from deformation and strain is taken out of the mold.

摘要： PROBLEM TO BE SOLVED: To increase an ink charging amount on a recess pattern and to make doctoring by suppressing an ink residue on an intaglio by providing an edge leveling portion passed through a gap on a surface of the intaglio, and an edge charging portion brought into contact with the surface of the intaglio and passing it. SOLUTION: The doctor blade 2 is constituted by integrating an edge leveling portion 2b with an edge charging portion 2a. The portion 2a is formed at its edge in a protruding shape such as a cutter edge or the like, and sharpness of an ink 107 is effectively provided at an end of a pattern while leveling the ink 107. Meanwhile, the portion 2b is formed in plane at its surface opposed to the surface of an intaglio 105, passed at a desired gap from the surface of the intaglio 105 to suppress a phenomenon of ejecting subsequently to a rake angle of a doctor by the ink 107, and a charging amount of the ink is assured. Thus, the ink charging amount on the pattern 1 is increased and hence stably ensured.

摘要： PROBLEM TO BE SOLVED: To conduct doctoring of a region of a large area efficiently and at a low cost. SOLUTION: In an apparatus or a method for intaglio printing wherein an intaglio 201 supplied with ink is moved relatively to a doctor blade 205 in doctoring and a pattern formed of the ink filled in the intaglio thereby is transferred onto a printing matter, the doctor blade 205 is made up of a plurality of doctor blades 205 each having a length smaller than the width of a pattern part 202 of the intaglio and these doctor blades 205 are so disposed as to take charge of different regions on the intaglio in doctoring. Moreover, the individual doctor blades 205 taking charge of the regions adjacent to each other are disposed in doctoring so that the adjacent regions may overlap partially each other and that the doctoring be conducted in a manner of overlapping in a prescribed width.

摘要： PROBLEM TO BE SOLVED: To improve a lack of an ink by heating one or more of a doctor blade, the ink and an intaglio. SOLUTION: An ink 3 is inked, for example, in a glass intaglio 2, and doctored by using an offset printer having a heater 4 at a stainless steel doctor blade 1. At this time, a doctor blade is regulate to always hold a predetermined temperature. That is, when the heated blade is passed while scraping the ink on an intaglio rubbing-off part by the heated blade in the case of doctoring, the ink in contact with the blade is heated by the blade to be easily rubbed off, faithfully scraped, and the ink is filled in the plate as a trace of a cutting edge of the blade. Accordingly, at this time, the ink is faithfully charged in a pattern of a recess part of the intaglio, and the ink of a necessary amount for stabilizing is charged in the plate by controlling the trace of the edge of the blade.

摘要： PROBLEM TO BE SOLVED: To make the intra-surface temp. distribution of electrode substrates to be heated uniform and to form the electrode substrates having high quality by mounting heating elements settable at an arbitrary heating temp. at every prescribed region on a pair of the electrode substrates. SOLUTION: The heating elements settable at the arbitrary heating temp. at every prescribed region are mounted at a pair of the electrode substrates. A pair of the electrode substrates are heated by the heat generated by these heating elements to cure adhesive beads. Namely, the heating elements 4b capable of heat generating independently at the central side and the outer peripheral side are mounted via heat plates 3b and cushion materials 2b at a pair of the respective electrode substrates 1a, 1b with the lowest part to heat the electrode substrates 1a, 1b in such a manner that the temp. is made higher on the outer periphery side than the central side of the heating elements 4b, by which the intra-surface temp. of the electrode substrates 1a, 1b is lowered. The adhesive pieces 8 are mounted at least on either side of the opposite surfaces of a pair of electrode substrates 1a, 1b arranged to face each other.
