摘要： PURPOSE:To supply molding material smoothly so as to prevent molding from becoming faulty by feeding the molding material through a through-hole in a flanged cylindrical metal fitting set in a mold into an elastic pipe molding cavity after pressing the molding material, and feeding it from the pouring hole in the mold to a material sump part. CONSTITUTION:A water hammer shockabsorber for faucet mounting leg incorporates a flanged cylindrical metal fitting on both ends of an elastic tube, and cured, stuck, and formed integrally in a mold. In this case, upper and lower flanged cylindrical metal fittings 5 are set on a first mold 1 which comprises a pair of metal fittings 11 and 12 provided with a cavity 12a for elastic tube molding, and plural through-holes 5a are formed in the flanges. Also plural pouring holes 2b which are connected from an upper material storing part 2a to a lower material sump part 2c are formed in a second mold 2. In addition, a molding material in the material storing part 2a is push-pressed by a third mold 3. Then, after the push-pressed molding material is poured from the pouring hole 2b into the material sump part 2c, it is fed through the through- hole 5a into the first mold 1.

摘要： PROBLEM TO BE SOLVED: To provide a usable water use terminal capable of greatly saving piping materials and executing labors and thawing frozen members in a single motion by means of a centralized operation, in a cold district. SOLUTION: The pipe from a water supply lead-in pipe is branched into a hot-water passage leading hot-water to a centralized temperature adjustment header 3 through a hot-water supplier A and water passage directly leading it to the header and mixing and adjusting the hot-water and cold-water and distributing it to a hot-water supply terminal and a water supply terminal to directly lead pipes to respective terminals. Further, heating wires coated with flame-retardancy resin are laid along the pipe wall to constitute a serial circuit against an electric source. In this way, the thawing operation can be carried out by turning on/off the electric source, using a synthetic resin pipe coated with a heat retaining material on the external side.
