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.

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.

摘要:
A thermoelectric converter has a N-type thermoelectric element, a P-type thermoelectric element, an endothermic electrode and a radiative electrode. One surface of the N-type thermoelectric element is attached to one surface of the endothermic electrode and the other surface is attached to one surface of the radiative electrode. One surface of the P-type thermoelectric element is attached to the other surface of the radiative electrode and the other surface is attached to the other endothermic electrode.
