  • Patent number: 7018672
    Abstract: A method of manufacturing multi-layer circuit board comprising: a hole forming step for forming through-holes or blind-holes in a plate-form or sheet-form board material, and a filling step for filling a paste into through-holes or blind-holes formed in the hole forming step by using a filling means. A second paste is supplied to the paste in the filling process by using a paste supplying means to stabilized a viscosity of the paste and the paste is reliably filled into the through-holes or the blind-holes.

  • Patent number: 6962352
    Abstract: A gasket provided with a sliding-treated layer on the surface of a fluorine rubber gasket body. The sliding-treated layer is a baked coated film of a sliding treating agent. The sliding treating agent is an aqueous emulsion containing a solid lubricant, an urethane-based resin as a matrix, and a reactive group-coupled alkyltrialkoxysilane series compound represented by the following chemical formula as an adherability modifier. X—CnH2n—Si(OR)3 {wherein X (reactive group) is an amino-containing group or an epoxy-containing group, n is a natural number of 2 to 4, and R is an alkyl group having a carbon number of 1 to 3}.

  • Publication number: 20040248041
    Abstract: The present invention aims to provide a printing plate capable of preventing paste of high viscosity adhering to an edge of a squeegee from being transferred to and left on a through hole of a printed circuit board when the paste is being filled by a squeegeeing method. The printing plate has a metal sheet (3) provided with a squeegee cleaning section (7) formed thereon and fixed to the back surface of a slanting area (5) of mask (2) attached to a plate framework (1). The through hole of the printed circuit board is filled with paste only after paste of high viscosity adhering to the edge of the squeegee is removed by the squeegee cleaning section (7), to prevent the paste from being left on the through hole, and thereby achieving the printed circuit board of excellent quality.

  • Patent number: 6776090
    Abstract: A circuit board with high quality is provided by preventing the falling of paste which comes around to the squeegee complementary angle side during the pattern printing or paste filling by the squeegeeing method. While lowering, the squeegee is passed through the inclined portion of a paste removing section (3) provided on a mask (2) before pattern printing or paste filling, whereby the paste on the non-printing side (complementary angle) of the squeegee can be removed; thus, a circuit board superior in quality is obtained.

  • Patent number: 6694612
    Abstract: A mask film includes a base material, a parting layer and a non-parting portion placed on the base material. Accordingly, an optimum adhesion strength of the mask film and a prepreg sheet can be maintained, and peeling between the mask film and prepreg sheet can be prevented. Further, by preventing the fusing adhesion between the mask film and prepreg sheet due to heat generated when forming penetration holes, a circuit board having an excellent quality is obtained.

  • Patent number: 4769059
    Abstract: A glass melting furnace includes a furnace body including for storing molten glass, an upstanding tank including a bottom member lying flush with the bottom wall of the furnace body and a rear wall remote from the furnace body, the upstanding tank communicating with the furnace body, a feeder disposed upwardly of the rear wall of the upstanding tank and communicating with the upstanding tank, and a drainage mechanism disposed in a corner defined between the rear wall and bottom member of the upstanding tank for draining out heterogeneous molten glass. The upstanding tank has a width smaller than the width of the furnace body. The drainage mechanism comprises a through hole having an inlet opening into the upstanding tank and an outlet opening at a rear surface of the rear wall, the through hole being tapered from the inlet toward the outlet.
