    摘要: There is disclosed a process for preventing the polymerization of a vinyl compound which comprises allowing water in an amount of 0.05 to 5% by weight based on the vinyl compound or a corrosion inhibitive substance selected from an alcohol, an inorganic acid or its salt, an aromatic carboxylic acid or its salt and a zinc-containing salt in an amount of preferably 0.01 to 5% by weight based on the same, to coexist with a metallic salt of dithiocarbamic acid, in preventing the polymerization of the vinyl compound with the metallic salt of dithiocarbamic acid. The above process makes it possible to effectively inhibit the polymerization of acrylic acid, methacrylic acid, etc. in the distillation system, etc. of the production process for the above acids as well as the corrosion of the equipment and machinery to be used therein and also to assure long-term stable continuous operation of the equipment and machinery.

    摘要: An optical disk apparatus includes a carriage, a plurality of objective lens support portions, and a plurality of magnetic field generating means. The carriage is placed to oppose an optical disk and held to be reciprocally movable between an outer peripheral portion of the optical disk and its central portion. Each of the objective lens support portions has an objective lens elastically supported by an elastic member. The magnetic field generating means move each of the objective lenses in a direction perpendicular to the surface of the optical disk and a radial direction of the optical disk. Some of the magnetic field generating means which are used, in pairs, for the objective lens support portions are shared by the plurality of objective lens support portions.

    摘要: A simulator apparatus collects communication information on a transmission line by a line information collecting module, extracts the communication information between a server and clients from the collected communication information by an information extracting module, and further discriminates the communication information necessary for a simulation on a protocol unit basis from the communication information and converts to a simulating procedure by a procedure converting module. A simulation processing module performs a simulating operation of the client for the server in accordance with a simulation definition file of the simulating procedure and operating conditions and stores an operating situation to a performance log file.
