Patent number: 9399051Abstract: The present invention aims to provide a DPP-4 inhibitor that is obtained by using a food as a raw material and that is suitable for oral ingestion from the viewpoints of flavor and absorbability, and a composition for the prevention and/or amelioration of diabetes which contains the DPP-4 inhibitor. The present invention provides a DPP-4 inhibitor obtained by treating an azuki bean or a kidney bean with a microorganism or a proteolytic enzyme produced by the microorganism. In particular, a preferable DPP-4 inhibitor can be obtained by hydrolyzing an azuki bean with a koji mold or a proteolytic enzyme derived from the koji mold to fragment a protein in the azuki bean.Type: GrantFiled: February 3, 2014Date of Patent: July 26, 2016Assignee: Kaneka CorporationInventors: Yuji Tominaga, Shinichi Yokota, Hozumi Tanaka, Hideyuki Kishida, Masayasu Kitagawa, Hiroshi Tachi, Toru Ota

Patent number: 7320550Abstract: A tapered roller bearing includes an outer race, an inner race, a plurality of tapered rollers, and a cage. A small-diameter end portion of the inner race is formed with a small flange portion for limiting axial movement of the tapered rollers and a cylindrical portion which has a less diameter than the small flange portion and is connected to an axial outer end of the small flange portion. The cage is formed at a small-diameter end portion thereof with a bent portion which is bent inward in a radial direction. A small-diameter end portion of the cage has a bent portion which is faced to an outer surface of the cylindrical portion of the inner race with a predetermined clearance therefrom such that a labyrinth is created between the cage and the inner race.Type: GrantFiled: January 12, 2007Date of Patent: January 22, 2008Assignee: JTEKT CorporationInventors: Kenichi Ono, Kunihiko Yokota, Hiroshi Tachi

Patent number: 5067007Abstract: Attempts have been made to increase the number of pins of packages accompanying the trend toward fabricating integrated circuits highly densely and in smaller sizes. The present invention provides technology for improving reliability in fabricating packages of the surface-mounted type that have increased number of pins. That is, when the packages are mounted on the wiring substrate, the lead pins that receive load from the axial direction exhibit bending strength which is smaller than the junction strength of solder at the junction portions. To achieve this object, the lead pins are made of a material having large resiliency such as a fiber-reinforced material, a transformation pseudo elastic material, an ultra-high tension material, or a heat-resistant ultra-high tension material.Type: GrantFiled: January 24, 1991Date of Patent: November 19, 1991Assignees: Hitachi, Ltd., Hitachi VLSI Engineering Corp.Inventors: Kanji Otsuka, Masao Kato, Takashi Kumagai, Mitsuo Usami, Shigeo Kuroda, Kunizo Sahara, Takeo Yamada, Seiji Miyamoto, Yuuji Shirai, Takayuki Okinaga, Kazutoshi Kubo, Hiroshi Tachi, Masayuki Kawashima
