  • Publication number: 20170268494
    Abstract: A fluororubber tube is provided, which is formed from a rubber composition containing a fluororubber, and not less than 3.8 parts by mass and not greater than 4.1 parts by mass of a polyol crosslinking agent and not less than 3 parts by mass and not greater than 7 parts by mass of a carbon black based on 100 parts by mass of the fluororubber. Thus, the fluororubber tube is made less tacky by suppressing the intrinsic adhesiveness of the crosslinked fluororubber without formation of a coating film which may otherwise complicate the structure of the tube and the production process of the tube or may result in contamination.

  • Publication number: 20170261134
    Abstract: A rubber tube has an inner surface at least partly roughed so that the ratio (Rz/D) of the maximum height Rz of the inner surface to the inner diameter D of the tube is not less than 0.038. The ratio (Rp/D) of the maximum peak height Rp of the inner surface to the inner diameter D of the tube may be not less than 0.019. The ratio (Rv/D) of the maximum valley depth Rv of the inner surface to the inner diameter D of the tube may be not less than 0.019. The ratio (Ra/D) of the arithmetic average roughness Ra of the inner surface to the inner diameter D of the tube may be not less than 0.0036. The ratio (Rq/D) of the root mean square height Rq of the inner surface to the inner diameter D of the tube maybe not less than 0.0046. Thus, the rubber tube has a reduced adhesiveness.

  • Patent number: 8822229
    Abstract: The inventions provides a method for immunologically determining a keratan sulfate level which method includes bringing an anti-keratan sulfate monoclonal antibody into contact with a biological sample, the anti-keratan sulfate monoclonal antibody exhibiting a relative reaction specificity between keratan sulfate-I and keratan sulfate-II represented by IC50KS-I/KS-II of 0.4 to 5, to thereby provide a signal; and detecting keratan sulfate contained in the biological sample from the signal. On the basis of the method, the invention also provides a joint disease detection method and a method for assessing the effect of a remedy for a joint disease and a candidate substance therefor. Through these methods, a very small amount of keratan sulfate contained in a sample, can be determined. Particularly, these methods can determine, at high-sensitivity and high-specificity, the total keratan sulfate including keratan sulfate-I, which have been difficult to determine through a conventional technique.

    Abstract: A recycling technique for long-pile artificial turfs is provided in which a spent artificial turf is recycled and formed into an elastic particulate substance suitable for use as a filler for long-pile artificial turfs. The particulate substance (5), with which the space among the piles (4) of an artificial turf (3) is filled, is obtained by using as a raw material an artificial turf comprising at least 50 wt. % thermoplastic resin, adding an elastomer to the raw material, and forming the resultant mixture into particles. The particulate substance (5) has a specific gravity regulated to 1.10 or higher and is used for the filling.
