Abstract: Provided is a submerged arc welding method that produces little fume, has good weldability, and is suitable for welding high-Mn-containing steel materials to be used in cryogenic environments. The method includes welding with a combination of a wire having a predetermined chemical composition and flux having a basicity [BL] of 1.5 to 2.4, while adjusting a welding heat input according to a groove cross-sectional area. In this way, a weld metal with high strength and excellent cryogenic impact toughness where the 0.2% proof stress at room temperature is 400 MPa or more and an absorbed energy (vE?196) in the Charpy impact test is 28 J or more can be easily manufactured.

Abstract: A release solvent composition for releasing a thermosetting resin coating film coated on a thermoplastic resin molded article, and the release solvent composition containing 1,1,2,2,3,3,4-heptafluorocyclopentane and aromatic alcohols and having no flash point.

Abstract: n-Propyl bromide based solvent compositions and methods for cleaning articles using said solvent compositions are provided. Such solvent composition comprise about 50 weight percent to 99 weight percent of n-propyl bromide, about 0.5 weight percent to 50 weight percent of alcohol, and at least 0.005 weight percent of a surfactant. Such solvent compositions remove at least one of water or water soluble contaminants. The solvent compositions and methods of the present invention are useful as a degreaser and/or cleaner in both for cold cleaning and hot rinsing systems for cleaning articles.

Abstract: Methods for cleaning articles using n-propyl bromide-based solvent compositions are provided. According to one method, an article to be cleaned is contacted with a solvent composition comprising about 50 weight percent to about 99 weight percent n-propyl bromide and about 0.5 weight percent to about 50 weight percent of an alcohol. Such methods remove at least one of water or water soluble contaminants. Such methods are useful as a degreaser and/or cleaner in both cold cleaning and hot rinsing systems for cleaning articles.

Abstract: A method for purifying an aqueous alkaline solution, which comprises: bringing a fibrous activated carbon into contact with an aqueous alkaline solution to remove a metal component other than alkali metals and alkaline earth metals from the aqueous alkaline solution.

Abstract: A coaxial cable connection assembly includes a cable tap connector for engaging with the coaxial cable, a transceiver for transmitting and receiving information signals to and from the coaxial cable via the cable tap connector, a drop cable connector for electrically connecting the transceiver to a station device, and two matable coupling members for engaging and electrically connecting the transceiver with the cable tap connector. The tap connector has an axis along which the coaxial cable is disposed when the connector is engaged with the coaxial cable. The tap connector also has an outer face substantially parallel to the axis thereof, and includes outer and center conductor contact members for respective electrical connections with the outer and center conductors of the coaxial cable. The transceiver includes a casing having first and second intersecting faces. The drop cable connector is mounted on the first face of the transceiver.
