Abstract: PURPOSE:To prevent the neighboring hollow threads from sticking each other and to make relative position to be uniform in the vessel by braiding numbers of hollow threads having liquid separating function into a three dimensional braided structural body. CONSTITUTION:In the hollow thread bundles consisting of plural hollow threads 2 having selective permeability, bonded parts 17, 18 are formed so as to adhere the outer surfaces of hollow threads each other in the vicinity of ends parts of the hollow threads 2. The passage 21-22, 23-24 are formed in the vessel 19 so as to communicate respectively to the hollow side and to the outer side of the hollow threads which are sectioned using the bonded parts 17, 18 as boundaries formed when the hollow thread bundles are received in the vessel. And, at least one set of the above-mentioned bundles is made of the three dimensional braided structural body. As a result, the mutual sticking of hollow threads, the area reduction of hollow thread membrane, and the biased flow in the vessel are eliminated.

Abstract: PROBLEM TO BE SOLVED: To realize the easy formation of even a curved surface portion having a comparatively smaller radius of curvature and, at the same time, of a substantially free shape under the state that both the strength and rigidity of a structure are ensured by a method wherein a plurality of sheets of core material are laminated to one another in the direction of the thickness. SOLUTION: A core material laminate 3 is produced by directly laminating a plurality of sheets of core material 2 made of a thin foam. Next, a fiber reinforced plastic(FRP) skin layer 4 is arranged on both the sides of the laminate 3 so as to produce an FRP structure 1 having a sandwich structure. In each core material 2, a curved surface portion 5 having a comparatively smaller radius of curvature is provided. At this time, the core material laminate 3, further the FRP structure 1 has the above curved surface portion 5. Furthermore, the aimed thickness of the core material laminate 3 is set by laminating a proper number of sheets of the core material on one another. Thus, under the state that the strength, rigidity or the like or the structure is ensured, the substantially free curved surface portion 5 is formed and the FRP structure 1 having the curved surface portion 5 having a comparatively smaller radius of curvature can be easily manufactured.

Abstract: PROBLEM TO BE SOLVED: To easily manufacture a lightweight, high strength and high rigidity FRP structure at a low cost by providing a resin diffusion means for a core with FRP reinforcing members arranged discontinuously any integrating reinforcing fiber bases and the core for an FRP plate with a resin. SOLUTION: Reinforcing bases 23 for forming FRP reinforcing members having parts extending perpendicularly with an FRP plate after molding are discontinuously arranged on one of the end parts of cores 22. Inside a mold 21, the cores 22 consisting of foams or the like are arranged and the reinforcing fiber bases 23 are arranged on at least both faces of the cores 22, each of which has a larger groove as a resin passage and many small grooves branching from the large groove. The resin is diffused in the planar direction of the reinforcing fiber bases 23 through the large groove and the small grooves and the reinforcing fiber bases 23 are impregnated with the resin thus diffused in the thickness direction of the base 23. Finally the impregnated resin is cured at normal temperature or by heating to obtain the completed FRP structure.

Abstract: PROBLEM TO BE SOLVED: To not only decrease friction coefficient of a moving body supporting part but increase the absolute energy quantity in the moving body itself so as to provide a reciprocation device hardly influenced from disturbance by giving a rolling part having flywheel effect to a moving body. SOLUTION: Electromagnets 2 also used for the role of guide rails are arranged in the vertical direction of a moving body 1, and the moving directions of the moving body in the vertical and longitudinal directions are restrained. Kinetic energy driving the moving body 1 in the right and left directions is generated by air guns 3 jetting air in accordance with movement of the moving body 1, and the air jet timing from the air guns 3 is decided by that the moving body 1 passes through optical sensors 4. The moving body 1 is constituted of a permanent magnet buried in the center of the base frame, and two sets of two wheels respectively provided on two positions in the right and left directions as a contact rolling part. The contact rolling part is rotated by contacting with the electromagnets 2 during movement of the moving body 1, and hence a flywheel effect is provided.
