Abstract: A transport system includes a traveling rail (1) which constitutes a transport route and a transport body (3) which is capable of traveling on the traveling rail in the longitudinal direction of the traveling rail. Flexible drive tubes (5) are arranged on the traveling rail in the longitudinal direction of the traveling rail. The transport body includes a traveling wheel (4) which is capable of rolling on the traveling rail and drive wheels (2) which are capable of rolling on the drive tubes upon receiving the rotational drive power generated by pressure of a pressure medium supplied to the drive tubes while depressing the drive tubes. The traveling rail includes a plurality of transport sections and the transport body is capable of receiving a rotational drive force from the drive tubes at every transport sections. If necessary, a transport route changeover switch which changes over the transport route can be provided between the transport sections.

Abstract: A pneumatic tube carrier which is pneumatically conveyed through a pneumatic tube is provided with a container body for carrying articles and a pair of elastic films provided in the container body with their peripheries held by the same. The pair of elastic films are stretched by the article disposed therebetween and hold the article by a shrinking force generated therein.

Abstract: A novel manufacturing process of mold containing continuous holes and used for filter materials, gas dispersive materials, and mold materials. By this invention, the epoxy resin mixture including an epoxy compound having one or more epoxy groups in each mole, a hardener which reacts with and hardens the epoxy compound, emulsifiers, water or water-surface active agent, and fillers respectively is used as the molding material. As the emulsifier, at least two kinds of three different kinds of nonionic emulsifiers of 4-8, 8-17, and 11-15.6 HLB respectively are used together.The molding material is cured to a desired shape to prepare a mold containing continuous holes and for molding, conventional methods such as hardening after casting, for example, are adopted.

Abstract: The first invention relates to a novel manufacturing process of mold containing continuous holes and used for filter materials, gas dispersive materials, and mold materials. By this invention, the epoxy resin mixture including an epoxy compound having one or more epoxy groups in each molecule, a hardener which reacts with and hardens the epoxy compound, emulsifiers, water or water-surface active agent, and fillers respectively is used as the molding material. As the emulsifier, at least two kinds of three different kinds of nonionic emulsifiers of 4-8, 8-17, and 11-15.6 HLB respectively are used together. This is the primary feature of the invention and no molding materials including such emulsifiers are known so far. The molding material is cured to a desired shape to prepare a mold containing continuous holes and for molding, conventional methods such as hardening after casting, for example, are adopted.The second invention relates to a novel casting mold suitable be for slip discharge casting.
