    摘要: A spherical body having a core and a surface layer is manufactured by a method comprising a preforming step in which a pair of sheet blanks (1) are formed into half-shells (11) in a two-part mold (2) having hemispherical concave mold halves by pressing each blank from one side while applying vacuum suction to the other side; a surface layer forming step in which the half-shells are loaded into another two-part mold (12) having pattern-forming projections, the core (19) is placed on one mold half, and the other mold half is joined thereto to close the mold, thereby pressing the core against the inner side of each half-shell, concurrent with which vacuum suction is applied to the outer side; and a molding step in which the surface layer is fused and solidified onto the core within the closed mold.

    摘要: A golf ball mold is prepared by inserting a dimpled hemispherical male die into a chamber in a frame, admitting hot liquid wax into the chamber, cooling and curing the wax to form a wax shape, covering the wax shape with a mix slurry of ceramic particles and a binder, drying and curing the slurry to form a ceramic shell around the wax shape, removing the wax shape from the ceramic shell, casting a molten metal into the ceramic shell, cooling and solidifying the metal to form a mold half, and removing the ceramic shell from the mold half. The mold is improved in molding precision, durability and cost.

    摘要: An air bag is made by forming a base cloth into the shape of a bag by stitching. The air bag is expanded by gas supplied from an inflator. Stitching of areas of the base cloth in the vicinity of the inflator is made non-extendable stitching, and stitching of areas of the base cloth distant from the inflator is made extendable stitching. As a result, even if the output of the inflator is high, gas leakage in the vicinity of the inflator can be prevented. Also, even if the output of the inflator is high, it is possible to suppress damage suffered by stitching thread in areas of stitching in the vicinity of the inflator.

    摘要: A hollow-fiber filtering module includes a casing having an open end and an inlet for introducing water to be treated thereinto. A bundle of hollow fibers is mounted within the casing, each of the hollow fibers having an open end. A fastening member sealingly joins the open ends of the hollow fibers to the open end of the casing in sealing relation thereto, the open ends of the hollow fibers opening to the exterior of the casing. Part of the hollow fibers are made of a microporous membrane having a portion of a hydrophobic nature, and the other hollow fibers are hydrophilic microporous membranes. Gas introduced into the filtering module can easily permeate the hydrophobic portions of the hollow fibers and is discharged through the bores of the hollow fibers from their open ends together with the filtered water. There is also disclosed a water purification device employing such a hollow-fiber filtering module.
