Title: Multi-conductor oxide superconducting wire and manufacture thereof
Inventor: KIYOFUJI MASAHIRO
IPC: H01B12/10
Filed: 1989-03-23
Abstract: PURPOSE:To enhance the critical current density in a magnetic field by forming a multi-core wire, in which crystals of filament are oriented. CONSTITUTION:A powder assuming superconductivity is put fully in a pipe, followed by regressive plastic processing to yield a covered single wire. Then a plurality of such single wires are inserted in the pipe, followed by regressive plastic processing to yield a covered sub-multi-wire, and then a plurality of sub-multi wires are incorporated in the pipe, followed by regressive plastic processing to yield a covered multi wire. This is subjected to rolling process into a tape-shaped wire, which is passed through a one-point concentrated furnace 4 with steep temp. gradient at a specified speed to undergo one-way heat treatment at a partial fusion temp. of 850-950 deg.C, and thus a wire 3 having filament with intense orientation is accomplished. This allows production of a multi-core metal covered wire with good characteristics, which can be used in energy application.

Filed: 1989-03-23
Abstract: PURPOSE:To obtain uniform sticking of zinc phosphate by chemical conversion treatment in the Al alloy sheet by once removing a surface layer of an Mg- contg. Al alloy sheet, thereafter subjecting it to heat treatment and regulating the oxidized film thickness and Mg/Al ratio to specified range. CONSTITUTION:An Al alloy sheet contg. >=0.6wt.% Mg is treated by chemical technique using, e.g. nitric acid and an alkaline detergent to remove a surface layer of seizure and an ununiform sheet surface formed by soaking, hot rolling, etc. Next, the Al alloy sheet is subjected to final heat treatment to obtain a product sheet having 50 to 150Angstrom  oxidized film thickness and 0.6 to 5 Mg/Al ratio. At this time, for <50Angstrom  oxidized film thickness, adhesion of zinc phosphate is deteriorated, and for >150Angstrom , heating temp. is needed to raise and good stock can not be obtd. As for the Mg/Al ratio, inconvenience similar to that in the oxidized film thickness occurs for <0.6 and >5.

Title: Method for preventing fat or oil from being oxidized
Inventor: NAMIKI KAZUKO
IPC: C09K15/34
Filed: 1990-03-20
Abstract: PURPOSE:To facilitate the prevention of oxidative degradaded of fat or oil (and a food containing the same) with the utilization of an agricultural waste by using lipid components which are contained in the shell and endodermis of a peanut. CONSTITUTION:The oxidative degradation of fat or oil and a food containing the same is prevented by using, as the antioxidant, lipid components which are contained in the shell and endodermis (pellicle) of a peanut. For example, when 0.2% crude lipid of the shell is added to lard of an oil type, the mixture exhibits oxidation resistance like tocopherol. Also, in a dressing of an oil/water emulsion type, when 0.2% hexane : ethanol (99 : 1) extract plus ethyl acetate extract of the shell is added, the oxidation resistance is stronger than that of tocopherol and the activity is comparable to BHA.

IPC: G02B6/13
Filed: 1989-03-27
Abstract: PURPOSE:To eliminate the need for a chemical etching treatment by growing the crystal film of a magneto-optical material only in the hollow grooves provided on a substrate surface to form a waveguide layer and forming a coating layer thereon. CONSTITUTION:A photoresist film is formed in the part to be formed with the optical wave guide by a resist pattern on the substrate 1 and a metallic film is formed by sputtering, etc., over the entire surface; thereafter, the metallic film on the resist pattern is removed together with the resist to expose only the part to be formed with the optical wave guide and is subjected to an ion beam etching or the like to form the hollow groove 2 having the inside surface of a specular surface state. A single crystal film 3 is grown over the entire surface of the substrate 1 if an operation to grow the single crystal is carried out. The optical wave guide 4 consisting of the single crystal film existing only in the hollow groove is formed if the single crystal film formed in the part exclusive of the hollow groove 2 of the part to be formed with the optical wave guide is removed by polishing. The surface of the single crystal film 4 in the hollow groove 2 is also made into the specular state by polishing and, therefore, the coating layer 5 can be formed thereon. The need for a stage for etching the crystalline film to remove the unnecessary part and to shape the film is eliminated in this way and the accuracy and efficient mass production is possible.
