摘要： A magnetic recording medium composed of an aromatic polyamide support, a magnetic recording layer arranged on one surface side of the support, and a back-coating layer arranged on the other surface side of the support is improved in its running durability, by forming the back-coating layer from solid particles and a binder in amounts of the range of 8/10 to 20/10, and further by placing a subbing layer of polyester resin or polyurethane resin having a Tg of 40.degree. C.-80.degree. C. and a polar group such as --SO.sub.3 M, --OSO.sub.3 M, --COOM and --OPO.sub.3 MM.sup.1 (each of M and M.sup.1 is hydrogen, an alkaline metal ion or an ammonium ion) between the support and the back-coating layer.

摘要： A storage system which comprises a first storage unit such as an optical disk incapable of rewriting; a second storage unit such as a magnetic disk capable of rewriting; a control table for registering addresses of the first storage unit in which data are desired to be rewritten and addresses of the second storage unit in which the write-in data are temporarily stored; and a control unit for controlling the second storage unit in accordance with this control table such that the data desird to be rewritten into said addresses of the first storage unit are temporarily stored in the corresponding addresses of the second storage unit. The present invention enables the first storage unit incapable of rewriting to operate as is capable of rewriting. Using an optical disk or other large-capacity storages as the first storage unit will provide a mass storage system capable of rewriting.

摘要： A process for producing aluminum by electrolyzing fused aluminum chloride together with an alkali metal halide to produce chlorine gas at the anode surface and molten aluminum at the cathode surface where the electrolytic bath is of a molten mixed salt consisting essentially of 2 to 15% by weight AlCl.sub.3, 15 to 70% by weight CaCl.sub.2 and/or MgCl.sub.2, provided the amount of CaCl.sub.2 does not exceed 40% by weight, and 83 to 15% by weight NaCl. Metallic aluminum can be produced by electrolyzing aluminum chloride at a high current efficiency reaching about 90 to nearly 100%.

摘要： Thermoplastic synthetic polymer fibers having powder of metal attached to the surface of the fibers are subjected to a treatment for increasing the oxidation number of said metal from zero to a plus value, that is, oxidation in a broad sense. The resulting conductive synthetic fibers support a layer of a compound of the metal, i.e. an oxidized product of the metal in a broad sense, firmly and undetchably thereon, and have as low an electric resistivity as 10.sup.5 .OMEGA./cm or less. The conductive fibers can be blended to ordinary synthetic fibers to improve their antistatic property, or can be substituted for expensive metal fibers. The thermoplastic synthetic polymer fibers are sheath-core fibers wherein the sheath has a lower melting point than the core.
