Abstract: PROBLEM TO BE SOLVED: To provide a support body to secure supporting strength at the time of runflat travelling and to restrain deformation of the supporting part when it is fitted on a rim and also to provide a pneumatic runflat tire.
SOLUTION: A load to the supporting part 26 is reduced and deformation of the supporting part 26 is restrained since slitting 30 of a leg part 28 opens from the outside in the tire widthwise direction and bending deforming quantity to the inside of the leg part 28 increases when fitting a support body 16 on a rim 12. Additionally, opening deformation at the slitting 30 on the leg part 28 is restrained since force is applied in a direction where the slitting 30 closes for the leg part 28 by work of car weight at the time of runflat travelling.

Abstract: PROBLEM TO BE SOLVED: To compose a pneumatic run-flat tire capable of reducing tire noise using a general rim and a pneumatic tire.
SOLUTION: The pneumatic run-flat tire 10 consists of the rim 12, the pneumatic tire 14, and a support body 16. The support body 16 is equipped with a support part 26 formed with a plate, and a rubber made leg part 28. A cover member 32 is fixedly provided on the inner peripheral surface of the support part 26 to compose a sub air chamber 34. The subsidiary air chamber 34 is divided into a plurality of small subsidiary air chambers 34A in a circumferential direction with partition walls 37. One communication hole 38 is formed with respect to respective small subsidiary air chambers 34A on the support part 26, and the small subsidiary air chamber 34A and the communication hole 38 compose a Helmholtz resonant absorber reducing tire noise. Since leg parts 28 at the both ends are formed with an elastic body, the support body 16 can be assembled to the general rim 12 along with the pneumatic tire 14 in the same procedure as a rim assembly of the pneumatic tire 14.

Abstract: PROBLEM TO BE SOLVED: To efficiently and uniformly peel off a coating deposited on a surface of a mother material of a material to be processed without imparting a damage to the mother material. SOLUTION: Cooled gas obtained by vaporizing liquid nitrogen is blown to a coating film layer 12 on a surface of a bumper 10, i.e., the material to be processed from a cooling nozzle 21 of a bumper surface cooling device 23 to quench the coating film layer 12 to a brittle temperature. Thereafter, a projecting material 24 is projected to the quenched brittle coating film layer 12 using a blast device 12. Thereby, the coating film layer 12 is peeled off from the mother material 11.

Abstract: PROBLEM TO BE SOLVED: To provide a method for producing a resin net molecular-oriented by uniaxial orientation which is buried in earth such as embankment and a sloped face to reinforce the earth. SOLUTION: The resin net is produced by a method comprising the first process for forming a boring part in a resin plate by press processing, the second process for heating the resin plate stretchably, the third process in which the heated resin plate is passed between rolls to be stretched by increasing the rotational speed of a rubber roll on the tip side, and the fourth process in which tension is applied in the stretching direction for the molecular orientation of a heated unstretched part by using the latent heat of an unstretched land part while a stretch part is cooled. 1 is the resin plate; 11 is a press (the first process); 12 is hot water (the second process); 13, 14 are rolls (the third process); 15 is a cooling/stretching process (the fourth process); 20 is the resin net after the third process; and 30 is the resin net as a final product.

Abstract: PROBLEM TO BE SOLVED: To obtain a tile having excellent decorativeness for giving decorating properties to a wall surface by casting a cavity formed in combination of lower and upper molds with a resin to mold the tile, giving a desired pattern to a front surface of the obtained tile, and forming a sealing material layer on its rear surface. SOLUTION: In the case of molding the tile for decorating a wall, first a lower mold 11 having a surface 11a for forming a front surface side of the tile 1, and an upper mold 12 having a surface 12a for forming a rear surface of the tile 1 are combined. Then, an ABS resin blended with an antibacterial agent and/or a mildewproofing agent is filled in the cavity 13 constituted of these surfaces 11a, 12a, and thereby the tile 1 is molded. Then, a desired patter 7 is given to the surface of the obtained tile 1 by a hot stamping method, a film transferring method or the like. Subsequently, the tile 1 is coated with an acrylic resin, which is crosslinked by emitting a UV ray to form a coated surface 8, and then the rear surface of the tile 1 is coated with a silicone sealing material layer 9.

Abstract: PROBLEM TO BE SOLVED: To prevent the generation of wrinkles in the angular corner parts of a sheet body to be a surface layer during molding by forming recessed parts close to the angular corner parts of a mold, collecting wrinkles generated in the sheet body during molding in the recessed parts, forming a final molding by removing projected parts close to the angular parts of the molding formed in the recessed parts. SOLUTION: Including all the four angular corner parts α of the inner surface 21 of an upper mold 2 forming a cavity, also in recessed parts, transparent films 3 are set, with optimum tension applied by a suction means such as vacuum sucking device, and are fitted to prevent the generation of wrinkles on the inner surface 21. After an adhesive is applied on one surface of the film 3, a decoration-printed polyvinyl chloride sheet as a decorating sheet is set on the inner surface of the film 3, and upper and lower molds 2 are closed. When an molding material is injected into the cavity, although wrinkles are generated in projected parts, a part to be a final molding has no wrinkle, and the four projected parts are cut off to make the final molding. In this way, the generation of wrinkles in a final molding angular corner part sheet body can be prevented.
