Patent number: 6114647Abstract: A bellows, of which one end portion is fixed to a movable lever passing through a vessel wall and the other end portion of which is fixed to the vessel wall, has a spring constant at a central portion in an expansion direction which is smaller than that at the end portions in the expansion direction. The bellows damps stress concentration at the end portions and improves the life thereof, without enlarging the size of the bellows. The bellows may be used in a vacuum switch.Type: GrantFiled: September 29, 1998Date of Patent: September 5, 2000Assignees: Hitachi, Ltd., Kuze Bellows Kogyosho Co., Ltd.Inventors: Ayumu Morita, Toru Tanimizu, Toshio Horikoshi, Yoshiharu Yotsumoto, Takanori Hashimoto

Patent number: 6005213Abstract: In an insulated type switchgear device in which a pair of arc electrodes are separably disposed in an opposing manner in a vacuum tube, and having a movable conductor extending from a back face of a movable one of the arc electrodes to the outside of the vacuum tube, the pair of arc electrodes are designed to be separated through a rotation of the movable conductor around a predetermined main axis.Type: GrantFiled: February 24, 1998Date of Patent: December 21, 1999Assignees: Hitachi, Ltd., The Tokyo Electric Power Co., Ltd.Inventors: Ayumu Morita, Takashi Sato, Youichi Ohshita, Tooru Tanimizu, Masayoshi Hayakawa, Toshio Horikoshi, Ryutaro Yamamoto

Patent number: 5952636Abstract: In a vacuum type switch gear device an L shaped stationary and movable conductors arrangement, a transitive portion from one spiral arc groove to a neighboring another spiral arc groove on the surface of a movable electrode defined by the terminating end portion of the one spiral groove, the starting end of the adjacent neighboring other spiral groove and the outer circumferential edge portion of the movable electrode is arranged in a substantially overlapping relationship in a vertical direction with the movable conductor. Thus an adverse effect of a current loop flowing through the movable conductor against an arc generated between movable and stationary electrodes is limited to thereby improve the circuit breaking performance.Type: GrantFiled: June 25, 1998Date of Patent: September 14, 1999Assignees: Hitachi, Ltd., The Tokyo Electric Power Co., Ltd.Inventors: Ayumu Morita, Takashi Sato, Youichi Ohshita, Tooru Tanimizu, Masayoshi Hayakawa, Toshio Horikoshi, Ryutaro Yamamoto

Patent number: 5892645Abstract: A protection apparatus for a spot network substation has a plurality of receiving lines connected between a network bus and a plurality of power sources. Each receiving line is connected to a primary switching device, a network transformer and a protector CB. A detector for detecting a phase of each receiving line voltage and a judging unit for judging the detected phase are provided on the primary side of each network transformer. A previously stored basic phase is compared with the detected phase of the receiving line voltage. If there is a lag in the detected phase of the receiving line voltage, it is judged to be a power-stop of the corresponding power source and the protector CB is tripped.Type: GrantFiled: July 29, 1997Date of Patent: April 6, 1999Assignees: Hitachi, Ltd., The Tokyo Electric Power Co., Inc.Inventors: Yoshiyasu Watanabe, Toru Tanimizu, Kazuo Kano, Yasunobu Kanou, Toshio Horikoshi, Koji Kondou, Ryutaro Yamamoto, Nobuhiro Kuroda

Patent number: 5597386Abstract: A hair dye consisting of an anti-hair antibody immobilized on a high bulky coloring material. The coloring material may be a coloring substance such as an inorganic pigment, water-soluble coloring matter, or water-insoluble coloring matter, or a composite of the coloring substance and a macromolecular carrier. Since it provides a good and strong coloring capability specific to hair, the hair dye of the present invention will neither stain the skin nor cause skin irritation. Further, the touch and feel of the hair will be improved.Type: GrantFiled: August 8, 1994Date of Patent: January 28, 1997Assignee: Kanebo, Ltd.Inventors: Shigeru Igarashi, Toshihiro Usui, Junichiro Hiraoka, Keiko Hashimoto, Hideyo Uchiwa, Umeji Murakami, Kenichi Sugimoto, Hiromi Minamino, Toshio Horikoshi

Patent number: 5439680Abstract: Cell-associated glucosyltransferase of S. mutans serotypes c, e or f producing dental caries was isolated and purified and its characteristics as an enzyme were revealed. Furthermore, an antibody against said enzyme was prepared from eggs of the hens immunized with said enzyme. Since this antibody effectively prevents adherence of the aforementioned S. mutans to tooth surfaces, it is useful as an effective component for a dental caries prophylactic composition.Type: GrantFiled: December 2, 1994Date of Patent: August 8, 1995Assignees: Kanebo Ltd., Ghen CorporationInventors: Toshio Horikoshi, Junichiro Hiraoka, Isamu Fujita, Tohru Tokoro, Yoshikatsu Kodama, Hideaki Yokoyama

Patent number: 5425937Abstract: Hair treatment compositions, hair damage protective agents and hair care products, each contain an active ingredient comprising an antibody which binds to human hair keratins which constitute intermediate-diameter filaments. This antibody can be produced efficiently and in a large quantities from the milk of a bovid animal immunized with said keratins. As this antibody binds to the hair specifically, it is effective in preventing the elution of proteins from the hair, imparting smoothness and flexibility to the hair, and improving the adaptability to combing and luster of the hair.Type: GrantFiled: August 4, 1993Date of Patent: June 20, 1995Assignee: Kanebo, Ltd.Inventors: Hideyo Uchiwa, Makoto Hirano, Umeji Murakami, Kenichi Sugimoto, Hiromi Minamino, Toshio Horikoshi, Minoru Ohta, Takusaburou Ebina

Patent number: 4510951Abstract: Disclosed are a method and apparatus for diagnosis of hair for permanent waving, in which the number of untwists of a twisted swatch of hair is counted to measure the waving efficiency, and the result of measurement of the waving efficiency is based to simply select the optimum processing condition for permanent waving which condition has been determined hitherto by relying upon the experience and sense of a beauty artist. The method comprises the steps of imparting twists to a swatch of hair, fixing the hair swatch at its both ends, applying permanent waving to the hair swatch with a waving lotion, releasing one end of the hair swatch in water to measure the number of untwists after processing, evaluating the permanent waving efficiency according to the following formula: ##EQU1## and selecting the optimum processing condition for the permanent waving of the specific hair on the basis of the evaluated waving efficiency.Type: GrantFiled: September 19, 1983Date of Patent: April 16, 1985Assignee: San-Ei Kagaku Co., L.T.D.Inventors: Katsuhiro Watanabe, Masayuki Minei, Toshio Horikoshi
