摘要： PROBLEM TO BE SOLVED: To improve function by a method wherein an overflow edge circumferentially zigzagging in the semidiametral direction in the planate shape is provided at the periphery of an induction plate provided at the circumference of an opening at the upper end of a water intake-drainage pipe. SOLUTION: A faucet member 10 is constructed by erecting a labyrinthine overflow edge 20 at the periphery at the upside of a flangelike induction plate 12 provided at the front end of a water intake-drainage pipe member 11. For the overflow edge 20, while large diameter edge parts 21 are provided at specified angular intervals at the outer diametral part of the induction plate 12, small diameter edge parts 22 are provided respectively at positions at the diameter smaller by a specified amount corresponding to parts being devoid at the edge part 21, and a shape zigzagging in the radial direction as seen in the planate view is formed by connecting each of corresponding ends of the edge parts 21 and 22 with an edge part 23 in the diametral direction. Then, the inside of the overflow edge 20 of the induction plate 12 is formed in a funnel-shaped form smoothly connecting at a specified curvature to an opening of the pipe 11. As the overflow edge is formed in a zigzagging shape, the overall length becomes longer than a circular overflow edge, and thereby the amount of water intake and drainage can be increased while reducing cost and furthermore, surface warm water can be taken efficiently.

摘要： PROBLEM TO BE SOLVED: To remove bottom mud precipitated/accumulated in a reservoir, and to simultaneously repair/reinforce a bank body of the reservoir by using the bottom and precipitated/accumulated in the reservoir as a banking material when creating levee widening banking and pressing-down banking for repairing/ reinforcing the bank body of the reservoir. SOLUTION: A solidifying material such as cement is added to bottom mud 14 of a reservoir, and is agitated/mixed to manufacture mixture 18. Next, the mixture 18 is left as it is for a prescribed curing period, and is cured/solidified to obtain a solidified mixture 22. Next, the solidified mixture 22 is excavated by a backhoe 24, and a mass 22A of the excavated solidified mixture 22 is crushed in the prescribed size (the particle size) by a crusher 26 to obtain crushed pieces 28. The crushed pieces 28 obtained in this way are carried to a banking creating part of a bank body to be used as a banking material.

摘要： PROBLEM TO BE SOLVED: To readily obtain precise nematode density distribution in a short time. SOLUTION: Natural electric potential of a field 3 is measured by a natural electric potential measuring device 2 in a first process to prepare electric potential distribution in the field 3. At the point at which natural electric potential exhibits different value among the natural electric potential distribution obtained by the first process, soil is collected in a second process. Then, ground density of root lesion nematode is measured from soil obtained by the second process and correlation between the measured density and natural electric potential at the collected point is judged in a third process. The density of soil organism of the field 3 is detected correspondingly to natural electric potential obtained by the first process based on the correlation between soil organism density and natural electric potential judged by the third process in a fourth process.
