    Abstract: PROBLEM TO BE SOLVED: To provide a stepped structure FRP-made propeller shaft capable of sufficiently ensuring necessary strength throughout the whole of the shaft by effectively reinforcing a part expected to be reduced in strength when forming in a stepped structure, and smoothly conducting filament winding at a manufacturing step. SOLUTION: In a propeller shaft provided with an FRP-made main cylinder having a helical winding layer of reinforced fiber, the main cylinder has a larger diameter portion, a small diameter portion, and a taper portion connecting the both diameter portions. The reinforced fiber of the helical winding layer continues from the large diameter portion to the small diameter portion through the taper portion. A winding angle to a shaft axial direction of the reinforced fiber in the helical winding layer becomes larger in the small diameter portion than the large diameter portion, the thickness of the main cylinder is thicker in the small diameter portion than the large diameter portion.

    Abstract: PROBLEM TO BE SOLVED: To provide an elevator cage which is lightweight and excellent in moldability and environmental conservation by including a plastic-ribbed sheet material as a component member. SOLUTION: Side plates 51a, 51b of a cage 56 including a ribbed sheet material, parts 52a, 52b of a ceiling board and parts 53a, 53b of a floor board are integrally molded to form integrated members 54a, 54b, and the integrated members 54a, 54b are connected together on the ceiling section and floor board of the cage 56. A back plate 55 is connected to form the cage 56. Flanges 57a, 57b, 57c are provided at junctions. The back plate 55 is formed with a component member including a ribbed sheet material. The elevator cage 56 which is excellent in rigidity and strength, is lightweight, can reduce motive power, and is excellent in moldability and assembling property can be obtained. It can be recycled, and it is useful in environmental conservation.

    Abstract: PURPOSE:To increase the speed of flame-resisting treatment by threading a precursor fiber through a fluidized layer in a state folded in multiple stages and attaching a porous material to at least one of gaps between thread guides of precursor fiber. CONSTITUTION:A precursor fiber T is threaded through a fluidized layer 4 in a state folded with turning rollers 12a-12c and 13a-13c. At least one of the spaces between the thread guides of the precursor fiber in the fluidized layer is provided with a porous material 31. The bubbles of the oxidizing gas in the fluidized layer is divided by the porous material. The pore size of the porous material is selected to enable the passage of the particles 30 of thermal medium.

    Abstract: PROBLEM TO BE SOLVED: To ensure a texture, which is close to a genuine natural stone or brick as near as possible and can not produce by painting, gel-coating or printing, by providing a layer consisting of a resin natural crushed stone particles or crushed brick particles is on at least one side of a fiber reinforced plastic panel. SOLUTION: In a fiber reinforced plastic decorative sheet 1, natural crushed stone particles 3 and a natural crushed stone particle/resin layer 4 are provided on the surface of a FRP panel 2. In this case, the natural crushed stone particle/ resin layer 4 can arrange on both the sides of the FRP panel 2. Further, instead of the natural crushed stone particles 3, crushed brick particles can also be used and, at the same time, the mixed particles of the natural crushed particles 3 and the crushed brick particles can also be employed. As the preferable compounding amount of natural crushed stone particles 3, the weight ratio of the resin to the particle is made to be 10 to 25% to 75 to 90%. In the natural crushed stone particles 3, the preferable compounding amount of the particles having the particle diameter 500 μm to below 5 mm and of the ones having the particle diameter 5 mm and below are respectively 20 wt.% to the total amount.
