  • Patent number: 9399051
    Abstract: 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.

  • Patent number: 7320550
    Abstract: 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.

  • Publication number: 20070104403
    Abstract: A bearing apparatus for supporting a pinion shaft comprises a pair of rolling bearings which rotatably support a pinion shaft to a case and are arranged side by side in a shaft direction between a pinion gear arranged at one end of the pinion shaft, and a companion flange attached outside the other end thereof. The rolling bearing on a companion flange side comprises an angular ball bearing, and a radius of curvature Ri of an inner ring raceway, a radius of curvature Ro of an outer ring raceway, and a ball diameter Bd of the rolling bearing may satisfy a relationship given by equations of Ri<Ro, 0.502×Bd?Ri?0.512×Bd, and 0.510×Bd?Ro?0.520×Bd.

  • Patent number: 5234866
    Abstract: According to the present invention, as improvement in the adhesion of inner leads with a packaging resin in a resin-sealed semiconductor device is attained by spreading leads on or near the circuit-forming face of a pellet, or on or near the main non-circuit-forming face of the pellet to extend the lengths of the inner leads on or under the pellet.

  • Patent number: 5067007
    Abstract: 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.
