Title: Surface treating agent for copper and copper alloy
Inventor: HIRAO HIROHIKO
IPC: C23C22/68
Filed: 1992-06-12
Abstract: PURPOSE:To obtain the chemical conversion film excellent in rust preventing property and thermal resistance by specifying the benzimidazole compd. which is contained in the pre-fluxing agent used at the copper circuit part of the hard and flexible printed circuit plate. CONSTITUTION:This surface treating agent contains 2-(cyclohexylalkyl) benzimidazole compd. (B) expressed by the formula as active component. In the formula, n is 0-6, each of R1, R2 is H atom, lower alkyl group or halogen atom and may be the same or different with each other. By allowing to contact the aq. soln. of this surface treating agent with the surface of copper or copper alloy, the chemical conversion film of compd. B which is locally formed into a copper complex is obtained. By allowing to stand or by heating this chemical conversion film, the compd. B is changed to the described copper complex, and thermally and chemically stable film is obtained. Further, because the compd. B is hardly soluble in water, the compd. B is dissolved using an acid.

Filed: 1987-07-17
Abstract: PURPOSE:To prevent the flaw of a microcapsule by superposing a light receiving sheet and an image receiving sheet, followed by irradiating a light for forming an image to the obtd. sheets, thereby reducing the distance of transporting solely the light receiving sheet. CONSTITUTION:The light receiving sheet 2 pulled out from a storage case 21 is supported by a guide roll 3 which is provided with connecting to the almost output of said case, and at the same time superposed with the image receiving sheet 6. A light reflected from an original is radiated on the superposed sheets 2 and 6 from a side of a transparent sheet 22 at an exposure point P.

Title: Producing apparatus for quickly cooled light-gauge metallic strip
Inventor: YASUDA TAKESHI
IPC: B22D11/06
Filed: 1983-09-30
Abstract: PURPOSE:To solidify a molten metal at nonuniform rates of solidification and to obtain a light-gauge strip having axial crystal or fine crystal grains by disposing partially materials having the heat conductivity of the value different form the heat conductivity of a roll material on the rotating and cooling surface of the roll. CONSTITUTION:The white part in the expanded view of a roll surface is the part where a roll material is exposed on the surface and black spots are the points where BN is embedded into the roll. The part 2 in the model diagram showing the section of the light-gauge strip corresponds to the BN part of the roll surface and the part 3 corresponds to the part where the roll material is exposed on the roll surface. The crystal grains beginning to crystallize and grow from the part 2 of BN have the smaller heat conductivity than the roll material and grow therefore to the smaller grains than the crystal of the part 3. The crystal grains of the part 3 on the contrary have a higher rate of solidification and grow to the grains larger than the crystal grains of the part 2 but there are the small crystal grains of the part 2 near said part and therefore the crystal grains grow by bending so as to cover the above-mentioned crystal grains and are parted in the midway of the growth, by which the smaller crystal grains 4 are formed.
