Patent number: 10156576Abstract: The purpose of the present invention is to develop: a method for selectively separating a glycoprotein derived from the central nervous system from a body fluid or a central nervous system cell; and a method for searching for an index marker for central nervous system diseases, which utilizes the aforementioned method. A protein derived from the central nervous system, which occurs in a trace amount in a body fluid or a central nervous system cell, can be selectively enriched by a two-stage separation procedure comprising removing a glycoprotein having sialic acid at a non-reducing terminal thereof from the body fluid or the central nervous system cell and then separating a glycoprotein having N-acetylglucosamine at a non-reducing terminal thereof.Type: GrantFiled: March 16, 2016Date of Patent: December 18, 2018Assignee: National Institute of Advanced Industrial Science and TechnologyInventors: Hisashi Narimatsu, Jun Hirabayashi, Atsushi Kuno, Hideki Matsuzaki, Yuzuru Ikehara, Hiromi Ito, Yasuhiro Hashimoto, Keiro Shirotani, Satoshi Futakawa, Hajime Arai, Masakazu Miyajima, Kazuo Fujihara

Patent number: 7549555Abstract: A flange is provided at the opening metal of a pressure container, and it extends toward the periphery of the container body at the bonding part thereof at which it bonds to the container body. The liner of the pressure container has a self-sealing part at which it abuts the flange to be sealed up together. On the outer peripheral side of the self-sealing part, a ring-shaped constraint member is provided in the outer periphery of the liner, and the constraint member is to restrict the diameter expansion of the liner to be caused by the expansion of the container body. The liner has an easily-displaceable part that is readily elongable and deformable, at the outer periphery thereof in the radial direction of the self-sealing part.Type: GrantFiled: December 24, 2003Date of Patent: June 23, 2009Assignee: Toyoda Gosei Co., Ltd.Inventors: Tetsuya Suzuki, Minoru Komada, Kazuo Fujihara, Yoshiaki Kondo, Takashi Maeno, Isamu Komatsu

Patent number: 7040306Abstract: A blowby gas ventilation system for an internal combustion engine capable of preventing oil from being diluted by efficiently and quickly exhausting a blowby gas together with a water content and the like from a crank chamber through forced ventilation of the crank chamber. The blowby gas ventilation system is intended for a four-stroke-cycle internal combustion engine. The system includes a fresh air introduction pipe, through which fresh air is sent from an outside of the internal combustion engine through a throttle portion to a crank chamber. The system also includes a blowby gas return passageway, through which the blowby gas is returned back to a downstream side of an air cleaner.Type: GrantFiled: August 24, 2004Date of Patent: May 9, 2006Assignee: Honda Motor Co., Ltd.Inventors: Ryuji Moriyama, Kenji Oki, Yuuki Muraoka, Ryuji Maeda, Kazuo Fujihara, Nobuhiro Shimada

Publication number: 20050006394Abstract: A high-pressure gas container is provided with a hollow liner portion made of resin and a regulating portion disposed on the outer peripheral side of the liner portion. Reinforcing ribs projected toward the hollow inside of the liner portion and used for reinforcing the liner portion are provided integrally with the liner portion on the inner peripheral side of the liner portion. Providing the reinforcing ribs results in increasing the strength of the high-pressure gas container. Moreover, providing the reinforcing ribs integrally with the liner portion makes it possible to reduce not only the number of parts and that of manufacturing man-hours required to produce the high-pressure gas container, so that the high-pressure gas containers are producible less costly.Type: ApplicationFiled: June 10, 2004Publication date: January 13, 2005Inventors: Kazuo Fujihara, Tetsuya Suzuki, Takashi Mitsuda, Takashi Maeno
