  • Publication number: 20020104122
    Abstract: This invention relates to a method for producing a plant with enhanced resistance to a pathogenic fungus, comprising transforming a plant with an expression vector comprising a DNA encoding a glucan elicitor receptor operably linked to a heterologous promoter, selecting a plant which has said DNA incorporated into a chromosome of said plant and which expresses said DNA, and recovering the selected plant. This invention also relates to a method for producing a progeny plant with resistance to a pathogenic fungus from said plant.

  • Patent number: 6148653
    Abstract: The present invention aims to provide a rolling system and a rolling method capable of avoiding the occurrence of a pinch fold by effectively preventing the zigzag movement of a rear end portion of a material to be rolled. The rotational speeds (rolling speeds) of work rolls (2) of a rolling mill stand (F.sub.1) from which the rear end of a plate material (6) releases, and a succeeding rolling mill stand (F.sub.2) are controlled to the same value. Moreover, the tension between the rolling mill stand (F.sub.1) and the rolling mill stand (F.sub.2) is controlled to zero. The difference in tension between a work side and a drive side can be made null between the rolling mill stand (F.sub.1) and the rolling mill stand (F.sub.2). Similarly, the difference in tension between the work side and the drive side can be made null between the plurality of rolling mill stands (F.sub.2 to F.sub.n) during release of the rear end of the plate material (6).

  • Patent number: 5758530
    Abstract: A hot rolling line is constructed by a pair or a plurality of pairs of rolling rolls disposed opposingly on an upper side and on a lower side of a workpiece (1) to be rolled that is pinched in between the rollers. A descaling apparatus (5) has jet flow nozzles disposed so that two jetted flows, being liquid, gas or plasma, are opposing flows so as to collide with the surface of a strip on the upstream side of the rolling rolls and then collide with each other. The jet flow nozzles are disposed, so as to incline in a direction to face each other so that the angle of inclination is 15.degree. to 60.degree. from the horizontal direction of the strip surface.
