  • Patent number: 9238688
    Abstract: Disclosed is a compound which exhibits a higher effect of preventing wrinkle formation, a higher effect of improving wrinkles, a higher effect of making the skin beautiful, and a higher effect of improving skin quality than conventional retinol and retinol derivatives in a sustained manner. Further disclosed are a method for producing the same, and an external composition for the skin and a sheet-shaped cosmetic each containing the same as an active ingredient. More specifically disclosed are retinol-modified collagen in which a dicarboxylic acid is attached to at least one hydroxyl group of collagen and retinol is attached to a carboxyl group of at least one attached dicarboxylic acid, a method for producing the same, and an external composition for the skin and a sheet-shaped cosmetic each containing the same as an active ingredient.

  • Publication number: 20130310540
    Abstract: An object of the present invention is to obtain a useful extract from aquatic animal tissues. The present invention provides a fish cartilage water extract containing a proteoglycan having a molecular weight of not less than 2,500,000 (250×104). The extract has a superior skin anti-aging effect (in particular, anti-inflammatory effect, skin barrier functionality improving effect, and skin water-retention ability improving effect). Moreover, the fish cartilage water extract of the present invention provides these effects not only through application to skin but also through oral administration.

  • Patent number: 7718307
    Abstract: A negative electrode material for a high input/output currant-type non-aqueous electrolyte secondary battery, comprising a carbon material having an average (002) interlayer spacing d002 of 0.355-0.400 nm determined by X-ray diffractometry and a true density of 1.50-1.60 g/cm3, and exhibiting a capacity (A) of at least 50 mAh/g in a battery voltage range of 0.3-1.0 V and a ratio ((A)/(B)) of at least 0.3 between the capacity (A) and a capacity (B) in a battery voltage range of 0-1.0 V when measured as discharge capacities with a counter electrode of lithium. The negative electrode material is non-graphitizable and has properties suitable for a negative electrode material for high input/output current non-aqueous electrolyte secondary batteries as used in HEV, etc.

  • Publication number: 20010039616
    Abstract: The present invention provides Internet contents providers with a carrier-free authentication method for mobile terminals that use the contents of an unofficial website. The parameter attached to the URL differs each time or within a specific period of time, and moreover, differs from user to user. Therefore, by using this method, even if all the information—URL, user ID and password—should leak out to a third-party user who poses as a legitimate user, a new parameter would be sent to the fraudulent user. The moment the new parameter is sent, the former parameter becomes invalidated. The legitimate user does not know the new parameter that is now in the hands the fraudulent user. Therefore, the URL that the legitimate user accesses will contain the former parameter. When this kind of access occurs, it would be judged as a double log-in, and access by both the fraudulent and legitimate user becomes invalidated.
