摘要:
A novel method for firmly bonding metal and ceramics comprising the steps of applying a composite plating composition consisting of a metal containing plating solution and fine particles of ceramic on a surface of metal to which the ceramic is to be bonded, thereby forming a metal plating layer on the surface having partially projected fine particles of ceramic, and then firing the coated metal in order to fuse the ceramic thereto.

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.

There are provided an even number of paired roll-shift type rolling mills 12a, 12b and a controller 16 for controlling the rolling mills 12a, 12b. Each of upper and lower work rolls 13 of each of the roll-shift type rolling mills has a predetermined crown curve and has a roll shifting mechanism 14 for axially shifting the upper and lower work rolls relative to each other. The controller 16 determines a shift amount of each rolling mill in order to obtain a predetermined cross section shape of a steel plate, shifts the work rolls of the rolling mill on the upstream side paired every rolling coil to thereby disperse wear on the roll surface, and moves the work rolls of the rolling mill on the downstream side of the pair in a predetermined direction by the same distance, thereby canceling the change in the cross section shape of the plate caused by the shifting operation for the wear dispersion.

In growing an oxide single crystal such as a garnet single crystal or ferrite single crystal by the liquid epitaxial process, the Bridgman process or the like, the melting-out of a platinum or platinum-based alloy-made crucible holding a melt for growing the crystal therefrom is prevented by bringing an electrode in contact with the melt or dipping the electrode into the melt in oxygen, air or an inert gas, applying electric current through the melt between the electrode and the metallic container and controlling the current so as to keep it at nearly zero.

Disclosed is a resin laminate having a surface layer excellent in antistatic properties, scratch resistance, and transparency. Also disclosed is a method for producing the resin laminate with a high productivity. Further disclosed is a transfer film for use in the production of the resin laminate. The resin laminate comprises a resin shaped article, an antistatic layer containing a π-electron conjugated conductive polymer and at least one resin selected from a polyester resin, a polyurethane resin, a polyesterurethane resin, an acrylic resin, and a melamine resin on at least one surface of the shaped article, and a cured coating film layer obtained by curing a curable resin on the antistatic layer. The method for producing the resin laminate preferably comprises the steps of forming the cured coating film layer and the antistatic layer on a mold using a transfer film, carrying out cast polymerization of a raw material for a resin, and detaching the resin laminate from the mold after the polymerization is completed.
