Patent number: 6841230Abstract: A long-fiber-reinforced thermoplastic resin sheet comprises short strands, each of which has a width of from 0.2 to 5 mm and a length of from 10 to 150 mm and is made of a unidirectionally long-fiber-reinforced thermoplastic resin. The short strands are oriented at random and are fixed together at intersections thereof. The long-fiber-reinforced thermoplastic resin sheet has a basis weight of from 30 to 500 g/m2 and is provided with openings therein. The long-fiber-reinforced thermoplastic resin sheet can be produced by evenly spreading and piling up short strands of substantially circular or elliptical sections, and subjecting the short strands to pressureless hot-melt adhesion or to hot-melt compression bonding under pressure such that the sheet has a basis weight of from 30 to 500 g/m2 and is provided with openings therein. The short strands of the substantially circular or elliptical sections have an average diameter of from 0.1 to 1.Type: GrantFiled: October 24, 2002Date of Patent: January 11, 2005Assignee: TS Tech Co., Ltd.Inventors: Yuji Yokoo, Toru Mizukami, Kengo Ozaki, Takashi Shimizu, Yukiko Takei

Patent number: 6686034Abstract: A new process for producing a fiber-reinforced thermoplastic resin molded product with a high mechanical strength and no heat substantial deterioration of the resin, by an efficient heating without applying shear stress to the fiber-reinforced thermoplastic resin base material and a molded product, for example, a tiptoe core for a safety shoe produced by said process are provided. The fiber-reinforced thermoplastic resin base material P1 in a string form or a tape form is scattered and accumulated in a vessel such as tube 11, and a heating gas passed to the accumulated base material to melt heat, and preferably press by a plunger 15, the base material P1, whereby a molten mass P2 is formed, and then the molten mass P2 is dislocated to a mold to be press-mold. Said base material preferably satisfies the following formula: {fraction (1/100)}≦&rgr;1/&rgr;0≦½, wherein &rgr;0 means a density where said base material is scattered and accumulated and &rgr;0 means a true density of said base material.Type: GrantFiled: February 28, 2001Date of Patent: February 3, 2004Assignee: Asahi Fiber Glass Company, LimitedInventors: Toru Mizukami, Kengo Ozaki, Masahiko Tominaga, Yuji Yokoo

Patent number: 6485931Abstract: According to the present invention, a process for producing a practical cholesterol-reduced substance by converting cholesterol contained in foods and feeds to coprostanol having very low intestinal tract absorbability by utilizing enzymatic action is provided. Cholesterol in a cholesterol-containing substance such as meat, egg, milk, seafood and cooked processed foods containing the same, or feeds for animals, poultry and pisciculture, and the like, can be treated with three kinds of enzymes which are a cholesterol dehydrogenase having an optimum pH in a neutral pH range and 4-cholesten-3-one dehydrogenase and coprostan-3-one dehydrogenase each having an optimum pH in a weak acidic range, or microbial cells containing the enzymes, for converting the cholesterol to coprostanol to reduce the amount of the cholesterol.Type: GrantFiled: January 2, 2001Date of Patent: November 26, 2002Assignee: Kyowa Hakko Kogyo Co., Ltd.Inventors: Chiaki Saitoh, Hideyo Kumazawa, Kazuo Aisaka, Toru Mizukami, Katsuhiko Ando, Keiko Ochiai, Ryoichi Katsumata
