  • JOINT, AND AIRCRAFT STRUCTURE
    Publication number: 20160194071
    Abstract: A joint (20) joins a plate member (26) with a preform (22), wherein an inclined part (28), which is inclined relative to a surface that is orthogonal to the direction in which a tensile load is applied to the plate member (26), is formed on a surface (25) that joins with the preform (22). Moreover, an indented part (38) corresponding to the shape of the inclined part (28) is formed on the preform (22) so that the inclined part (28) of the joint (20) is embedded into the indented part (38). The joint (20) is embedded in and bonded to the preform (22). As a consequence, the strength of the bonding surface of the joint (20) and the preform (22) becomes greater.

  • Functional food containing sodium tricaffeoylaldarate
    Patent number: 8372890
    Abstract: Components that demonstrate an ?-glucosidase inhibitory activity and hyperglycemic inhibitory activity have clearly been provided from among the components included in Yacon. The present inventors found that as a result of screening for a strong anti-oxidant component in a Yacon aerial portion extract, an antioxidant activity was converged in a DIAION HP-20 column chromatography 50% methanol-eluted fraction of hot water extract. Thus, since a previously unidentified high-content component was confirmed, the present inventors conducted purification thereof, and thereby separated TCAA. As a result, this TCAA was found to be the component that demonstrates the ?-glucosidase inhibitory activity and hyperglycemic inhibitory activity.

  • Wobble information recording method, information recording medium, and recording and reproduction method and apparatus thereof
    Patent number: 8149682
    Abstract: An optical disk and a method for identifying the optical disk making it possible to identify a recording system of the optical disk easily in a short time by a recording and reproduction apparatus when a groove-recording system and a land-recording system are both employed in one kind of optical disk, such as, for example, a BD-R. Specifically, a polarity upon reproducing wobble information is made to be the same in both an optical disk of groove-recording system and the optical disk of a land-recording system. The recording system of the optical disk that shows the same wobble polarity irrespective of the recording system can be easily detected by finding a tracking polarity that can recognize the wobble information by changing the tracking polarity, whereby the start-up time of the recording and reproduction apparatus can be shortened.
