Abstract: A stage for heating and cooling an object installed in a chamber 1 includes : a stage body 5, 6 that has a mounting surface on which an object is mounted; a heating unit 7 for heating the mounting surface; and a cooling unit 8 for cooling the mounting surface. The stage body 5, 6 also has a first groove 10 into which the heating unit is inserted and a second groove 10 into which the cooling unit is inserted. The gap between the first groove and the heating unit and the gap between the second groove and the cooling unit have a heat-conductive medium.

Abstract: An eggshell membrane separation system of separating a broken egg into an eggshell and an eggshell membrane (100) including: a pulverizer (10) that pulverizes the broken egg; an alkaline water tank (20) in which alkaline water is synthesized; and a separation tank (30) in which the alkaline water is supplied from the alkaline water tank and the broken egg pulverized by the pulverizer is separated into the eggshell and the eggshell membrane, wherein the alkaline water discharged from the separation tank is returned to the alkaline water tank (20) and reused. The eggshell membrane separation system can improve a separation property of an eggshell and an eggshell membrane and smoothly discharge the eggshell precipitated in the separation tank.

Abstract: Accordingly, the present invention is a soft tire assembly of a thick elastic layer of a foamed elastomer having an outer peripheral surface and cells in the foamed layer that are open to the exterior through the outer peripheral surface, or a mixture of cells open to the exterior and closed cells, wherein the expansion ratio of the foamed elastomer is from 1.5 to 6.0, and the elastomer has a specific gravity of from 0.5 to 2.0. The layer is mounted on a wheel rim, suitably of a metal, having an outer peripheral surface coated with a resin, and the foamed elastic layer is attached onto and about the outer peripheral surface of the wheel rim.
