    Abstract: Methods and means are provided for the modification of the reactivity of plant cell walls, particularly as they can be found in natural fibers of fiber producing plants by inclusion of positively charged oligosaccharides or polysaccharides into the cell wall. This can be conveniently achieved by expressing a chimeric gene encoding an N-acetylglucosamine transferase, particularly an N-acetylglucosamine transferase, capable of being targeted to the membranes of the Golgi apparatus in cells of a plant.

    Abstract: An oil-tempered wire for a cold-formed coil spring having a quality equivalent of or higher than a hot-formed coil spring is provided. A cold-formed coil spring made from the oil-tempered wire is also provided. Material used is the steel which contains, in weight percentage, 0.35 to 0.55% C, 1.8 to 3.0% Si, 0.5 to 1.5% Mn, 0.5 to 3.0% Ni, and 0.1 to 1.5% Cr. The ferrite fraction in the microscopic structure of this material is set to 50% or less. Hot rolled wire is cold drawn with a predetermined reduction of area, and a heat treatment using high frequency induction heating is conducted. It is preferable to set the maximum heating temperature between 900° C. to 1020° C. (favorably 950° C.) and holding time between 5 to 20 seconds. It is preferable to make the oil tempered material to have the grain size number of 9 or more, and the tensile strength from 1830 to 1980 MPa.

  • Publication number: 20080155791
    Abstract: To provide a knotless cord that is capable of exerting sufficient tensile strength of a fibrous body. A knotless cord has a sleeve and a fibrous body inserted into the sleeve, wherein the sleeve and the fibrous body are connected to each other by applying tension in a longitudinal direction of the sleeve and then tightening the sleeve. Moreover, in the knotless cord a locking portion for preventing the fibrous body from slipping out of the sleeve is provided in at least two sections (first locking portion, second locking portion). Therefore, stress generated by applying tension is dispersed throughout the entire fibrous body, while preventing the fibrous body from slipping out of the sleeve, whereby stress concentration occurring in each locking portion is alleviated.
