Abstract: An omnidirectional wheel whose outer circumference surface is formed by pluralities of rollers, and includes a rotating part that rotates around a rotation axis. A plurality of supports are arranged in a circumferential direction of the rotating part and each mounted on the rotating part. The rollers include a plurality of first rollers and a plurality of second rollers. Each support has a first arm supporting one end side of a corresponding first roller of the plurality of first rollers, and a second arm supporting the other end side of the corresponding first roller. A corresponding second roller of the plurality of second rollers is supported by the first arm of one of two supports that are adjacent to each other in the circumferential direction and the second arm of the other one of the two supports.

Abstract: Liquid curable resins, such as unsaturated polyester resins, unsaturated epoxy resins, polymethyl methacrylates, are cured in a mold, the casting surface of which, is made of a vinyl alcohol-olefin copolymer to produce a shaped resinous article with an improved and even surface gloss.

Abstract: An aluminum atom- and monocarboxylic acid residue-containing polyester is provided. Using the polyester as an adhesive or a base, laminates and laminated hollow vessels which comprise, as the constituent elements, the polyester and an ethylene-vinyl alcohol copolymer can be produced. The laminates and laminated hollow vessels are suitable for use as packaging materials or containers for food and drink.
