摘要:
A printing plate lock-up apparatus for a plate cylinder in a printing press comprises a groove defined in the plate cylinder and having an essentially circular cross section, the groove having an opening end opening to the outer periphery of the plate cylinder and having a width in the circumferential direction smaller than the internal diameter, the opening end having one edge engageable with a turned back edge of the printing plate, an engaging member disposed along the groove and having mating surfaces slidably contacting with the inner periphery of the groove for permitting rotation of the engaging member relative to the groove, the engaging member having an engaging hook engageable with a turned back edge, and having a thickness permitting withdrawal and installation through the opening end, and an operation assembly cooperating with the engaging member for operating the latter to rotate within the groove, the operation assembly maintaining an angular phase of the engaging means at least in the position where the engaging hook of the engaging member hooks the trailing end side turned back edge.

An offset printing apparatus provides good adhesion of ink onto the roller of the feeding route by efficiently fractionizing the dampening fluid supplied to the ink device. An ink device has an ink feeding route including an ink metering roller and an ink storage device whose distance toward the revolving direction of the upstream roller of said ink feeding route gradually decreases.

A lithographic press includes a plate cylinder having an outer surface which includes a first outer section and a second outer section, and at least one printing plate disposed around one of the first and second outer sections in parallel to a rotational axis of the plate cylinder. The other of the first and second outer sections is uncovered and exposed to the ambient environment. The lithographic press also includes an ink supplying device which feeds ink to the at least one printing plate and the other of the first and second outer sections, and an ink removing device having a contact member which contacts the other of the first and second outer sections of the plate cylinder and removes ink therefrom. A method for removing ink from the other of the first and second outer sections includes removing the ink by way of contact between the ink removing device and the other of the first and second section of the outer surface of the plate cylinder.
摘要:
A method of manufacturing a resin-encapsulated semiconductor device, which includes the steps of, mounting a semiconductor element facedown on a substrate provided with a wiring circuit with a main surface of the semiconductor element being faced to the substrate, positioning the substrate bearing the semiconductor element in a mold together with a sealing resin, and applying a pressure onto the sealing resin to move the sealing resin to a space between the semiconductor element and the substrate, to the sides of the semiconductor element and to the bottom surface of the semiconductor element, thereby sealing the semiconductor element with the sealing resin.

A web width adjusting device comprises a pressure force applying unit for applying pressure force to one side surface of a paper web which is successively traveled through two or more printing sections. Further the web width adjusting device may also include a counter pressure applying unit to apply counter pressure to the other side surface of the paper web. The pressure applying unit (and the counter pressure applying unit) deformes the paper web in a wavy surface which causes the width of the paper web to be shortened. The adjusting factors for the web width are controlled by automatic control system which detects traveling condition of the paper web, the generation of shears in printing, etc.
摘要:
A web width adjusting device can adequately adjust the width of paper web which travels through at least two printing sections. The travelling web is sandwiched by a pair of wave forming devices including a plurality of fluid ejectors which are aligned in the width direction of the paper web. The fluid ejectors of one alignment face alternately the other alignment to alternately eject fluid to both sides of the web.

摘要:
This invention relates to an offset type rotary press adapted for a color printing system, with printing sections, which prevents print-shears and produces printed matter in high quality. The system of this invention includes an extending area which supplies to the travelling paper web the power to extend in width direction, and at least two printing sections arranged in sequence at the position where the paper web travels after passing through the extending area.

There is disclosed a method for manufacturing a printed circuit board in which fine copper circuit patterns are transferred onto a thermoplastic resin, without producing a large amount of waste liquors in which copper is dissolved unlike in a subtract method. The method for manufacturing a printed circuit board includes the steps of manufacturing a printed circuit original plate having protruding patterns which have the same shape as circuit patterns to be formed and a height at least the same as the thickness of a copper foil used and each of which is constituted by a flat or projecting curved surface to be brought into contact with the copper foil and side surfaces different from the flat or projecting curved surface, and heating under pressure the protruding patterns of the original plate against a thermoplastic resin with the copper foil interposed therebetween to transfer portions of the copper foil in contact with the protruding patterns onto the surface of the thermoplastic resin, thereby forming the circuit patterns.
