Disclosed is a coating material for forming a gas barrier. The coating material includes a polyalcohol polymer, a polycarboxylic acid polymer, and a divalent or higher-valent metal compound whose surface is coated with a poorly water-soluble component, or alternatively a monovalent metal compound whose surface is coated with a poorly water-soluble component and a divalent or higher-valent metal compound whose surface is coated with a poorly water-soluble component. By applying this coating material to a plastic substrate layer, a gas-barrier multilayer body having a gas-barrier layer formed thereon is obtained.

A data transfer device is disclosed whereby both spoken conversation and transfer of data can easily and conveniently be carried out with a minimum of manual steps and repetitions operations. The disclosed device includes first telephone number memory for storing a telephone number of a remote communication node when the data transfer device originates a communication session; second telephone number memory for storing a telephone number of the remote communication node when the remote communication node originates the communication session; start command generating circuit for generating a start command; and data transfer circuit for transferring data. The above mentioned data transfer circuit is such that when the start command generating circuit generates a start command and the data transfer device has originated the communication session, the data transfer circuit initiates a connection over a channel for transmission of digital data between the data transfer device and the remote node corresponding to the telephone number stored in the first telephone number memory, and when the start command generating circuit generates a start command and the remote node has originated the communication session, the data transfer circuit Initiates a connection over a channel for transmission of digital data between the data transfer device and the remote node corresponding to the telephone number stored in the second telephone number memory.

In cation exchange membranes having a multi-layer structure consisting of two or three layers or more each having different equivalent weight and/or different kind of ion exchange group used for the electrolysis of alkali metal chloride according to an ion exchange membrane process, a homogeneous cation exchange membrane which comprises that at least one outer layer having a lower water content of both outer layers of said membrane has a roughened surface so that the amount of hydrogen gas bubbles generated from the cathode and attached to the membrane surface is the least whereby the electrolysis voltage is the lowest and the process for the production thereof.
摘要:
The use of a perforated plate anode in combination with a cation exchange membrane has been found to be extremely effective for rendering the current distribution in the cation exchange membrane uniform in practice of the ion exchange membrane process for the electrolysis of an aqueous solution of an alkali metal chloride. The uniform current distribution in the cation exchange membrane is, in turn, effective for preventing elevation of the electrolytic voltage and prolonging the life of the cation exchange membrane. Further, when the coating of the perforated plate anode on its front surface and the inner wall surfaces of the openings has a thickness larger than that of the coating on the back surface, the perforated plate anode has high durability and exhibits low electrolytic voltage for a long time as compared with the perforated plate anode having, on each surface, a uniform-thick coating.

A packing for use in a steel-pipe hydraulic testing apparatus, consisting of: an annular body having an annular cut in its inner peripheral portion; a plurality of backing pieces fastened to the wall of the annular cut at a given circumferential spacing and directed in the radial direction; and a plurality of adapter pieces embedded in the inner peripheral walls of the annular body of the packing at a given circumferential spacing and exposed to the annular cut, so that the aforesaid plurality of backing pieces may be each slidable on the surfaces of a pair of adjoining adapter pieces. This packing is contracted due to a hydraulic pressure being applied to the outer periphery of the body of the packing, and as a result the respective adapter pieces will slide on the surfaces of the adapter pieces in the circumferential direction of the packing.
摘要:
An equalizer device for a parking brake including an equalizer body that is formed by connecting paired side plates, which extend parallel to each other from a back plate so as to form a U-shape and a synthetic resin member that is fixedly arranged inside the equalizer body. The equalizer body includes paired engagement holes, paired insertion holes, and paired slits. Portions of the back plate, at which the engagement holes are formed, serve as the engagement portions. The synthetic resin member has a substantially flat plate shape that is arranged so as to face a portion of an inner face of a first side plate. The portion is a part of the U-shape, and extends parallel to the first side plate. The synthetic resin member includes paired gate portions and an engagement lug. The synthetic resin member is fitted to the equalizer body by the engagement lug.

摘要:
The present invention provides a metallic coating having a sheen and having a discontinuous structure at high productivity and low cost by using sputtering. A resin product includes a resin base material, and a metallic coating having a sheen and a discontinuous structure that is deposited on the resin base material so as to include a portion in which a high-formation metal that relatively readily forms a discontinuous structure when using vacuum vapor deposition is sputtered, and thereafter, a low-formation metal that does not relatively readily form a discontinuous structure when using vacuum vapor deposition is sputtered. The high-formation metal and the low-formation metal are selected from at least two species of metals whose crystal structures are identical and whose lattice constant difference is within 10%.
