Abstract: The purpose of the present invention is to provide a heat release sheet and a heat sink that have excellent heat conductivity to both of plane direction and orthogonalized direction and can efficiently release heat which generates from a notebook computer and a plasma television etc. The heat release sheet is comprised of an expansive graphite sheet and a reticulated body, wherein said reticulated body is comprised of metal wire, and it is overlapped on both sides of said expansive graphite sheet, and said expansive graphite sheet and said reticulated body are combined by metal rolling process. The heat sink is comprised by forming the heat release sheet.

Abstract: A packing material wherein one or a plurality of hard metal wire and one or a plurality of soft metal wire are tied up or twisted in a bundle to construct a weft material wherein the ratio of the number of the former to the number of the later is 1:1-0.3, the weft material is put in weft knit processing such as plain stitch, rib stitch, pearl stitch, welt stitch, half cardigan, full cardigan, plating stitch and inter-lock stitch, and Brinell hardness of said hard metal wire is 90-240 (Kg/mm2) and Brinell hardness of said soft metal is 40-55 (Kg/mm2).

Abstract: The present invention relates to gland packing materials made from expansive graphite, gland packing made from expansive graphite made from the materials, and a producing method of gland packing made from expansive graphite; braiding thread is a filamentose with winding or twisting a strip laminated sheet that a bundle of sprit fiber is laminated and unified through an adhesive layer so as to be a reinforcing material, and a cord body is constructed by braiding the braiding thread, then a packing is constructed by pressure forming this cord body.

Abstract: This invention relates to a reduced water producing apparatus, which can mass-produce reduced water, wherein oxidation-reduction potential maintains for a long period successively, from not only industrial water, natural water but pure water speedily and inexpensively, and that suited for industrial mass production of reduced water. The apparatus have a water tank, at least one electrode plate unit, and a voltage impressing means for impressing high-frequency alternating voltage, wherein the electrode plate unit includes two alternating electrode plates in which alternating voltages impressed by the voltage impressing means are varied to be modulated waves of mutually opposite phases and a ground electrode plate arranged to oppose the two alternating electrode plates, and wherein surfaces of these electrode plates are formed of titanium or platinum.
