  • Method of screening elicitor inducing the production of phytoalexin in rice and rice disease controlling agent containing elicitor as the active ingredient
    Patent number: 6146893
    Abstract: An object of the present invention is to provide a method for screening elicitors that induce the production of phytoalexins in rice plants, and agents for controlling rice diseases; and relates to a method for screening elicitors that induce the production of phytoalexins in rice plants, wherein the aforementioned elicitor screening method is characterized by using rice seedlings as the test plant, applying a test sample on a suitable part of the rice seedlings, and then screening the elicitors using the phytoalexins produced in the plant bodies as marker substances, as well as to agents for controlling rice diseases containing as an active ingredient a specific compound having an action in inducing the production of phytoalexins in rice plants.

  • Overlocking sewing machine and method for performing overlock sewing in overlocking sewing machine
    Patent number: 5134948
    Abstract: An overlock sewing machine having a loop spreading member which provides a retracted position and an operative position. In the retracted position, the loop spreading member is moved away from one side of needle hole slots, which one side being positioned farther from an edgeline of a workpiece. In the operative position the loop spreading member is engageable with a chain and the chain is insertable over the outer tongue upon shifting of the chain portion located at its needle side toward a workpiece feed-in side. The sewing machine further includes drive means connected to the loop spreading member for moving the loop spreading member from its retracted position to the operative position prior to a shifting operation of the chain toward the workpiece feed-in side with respect to positions of the needles.
