A multi-layer circuit board capable of reducing an electrical resistance between circuit patterns positioned inside the circuit board and a through-hole connection conductor. A plurality of circuit patterns are superposed on each other with a plurality of insulating layers being alternately interposed therebetween in turn. A solution in which ultrafine metal particles of the independent dispersion type such as silver, gold, palladium or the like are contained in a colloid-like manner is applied so as to extend from one of lands through an inner surface of a through-hole to the other land. Then, the solution is calcined to form a metal particle film, The metal particle film is coated thereon with a conductive paste such as a resin/silver paste or the like, which is then calcined to form a conductive paste layer.

This invention provides a circuit board having an electric component which has an electric element smaller than a conventional element. A circuit pattern (5) which includes a pair of contact electrodes (3, 3) is formed on the surface of a board (1) made of an insulating material. A photoresist film (7) is formed on the surface of the board (1). At least one electric element forming hole (9) is formed in the photoresist film (7) by a lithography technology so as to expose at least part of the pair of the contact electrodes (3, 3). The electric element forming hole (9) is filled with an electric element forming paste material to form an electric element (13). A protective film (15) made of a synthetic resin is so formed as to cover the electric element forming hole (9).

摘要:
A process for producing a phase retarder film or sheet, which comprises subjecting a stretched thermoplastic resin film or sheet to thermal relaxation at a temperature not lower than the glass transition temperature of the thermoplastic resin to shrink the film or sheet in the stretching axis direction while suppressing the expansion of the film or sheet in a direction parallel to the film or sheet surface and perpendicular to the stretching axis.

Disclosed is a molding material for extrusion foam molding from which woody molded foam of high quality can be obtained. From the molding material, woody molded foam of high quality with no defects is efficiently produced. Constituent materials comprising woodmeal and a thermoplastic resin as major components and containing 1-5 wt % alkane having a molecular weight of 300-1,000 g/mol are melt-kneaded until the components come into an evenly dispersed state, and the resultant mixture is molded into pellets having a given diameter to obtain a molding material. Subsequently, this molding material is extrusion-molded into a given shape together with a blowing agent by means of an extrusion molding device, thereby obtaining woody molded foam. The extrusion molding is preferably conducted in a manner such that the extrudate (25a) extruded from the extruder (12) is introduced into the molding chamber (31) of a molding die (30) while keeping the extrudate in the pressurized state and the extrudate (25a) is released from the pressure upon introduction into the molding chamber (31) of the molding die (30) to foam the extrudate (25a).

A stapler processing apparatus includes a paper jogging tray 6 for a collated sheet 3, a paper jogging unit 7 for jogging the collated sheet 3 by pressing it on the tray 6 by a presser jogging member 13, a stapler 8 for stapling the collated sheet 3 jogged by the paper jogging unit 7 and a paper discharging unit 9 for discharging the collated sheet 3 stapled by the stapler 6 from the tray 6. In operation, when the stapler 8 staples the collated sheet 3, it is forced to the tray 6 while making an upper driven roller 30b in close contact with a lower drive roller 30a. After stapling by the stapler 8, the paper jogging operation of the paper jogging unit 7 is stopped and the upper driven roller 30b is separated from the lower drive roller 30a to release the collated sheet 3 from it nipped state once. Subsequently, the upper driven roller 30b is brought into close contact with the lower drive roller 30a again and the discharge operation is started.
