Title: Method and apparatus for rotational molding
Inventor: YAGI TAKAYASU
IPC: B29C41/46
Filed: 1996-10-11
Abstract: PROBLEM TO BE SOLVED: To prevent the occurrence of shrinkage in molded articles by shortening the cooling period of time of the molded articles. SOLUTION: Synthetic resin melted by heat is allowed to adhere onto the cavity of a mold A with rotation of the mold A, and thereafter the heating is stopped for letting the mold to cool. Subsequently, rotation of the mold is stopped. By keeping this state, air is supplied from an air supplying port 11 into the molded article via an opening of the molded article, and while maintaining the inner pressure of the molded article constant, supply and exhaust of air are conducted by the use of the air supply port 11 and an air exhaust port 12, then by activating a mist generation device, a mist of 10μor lower is supplied into the molded article in order to bring the mist in contact with the inner surface of the molded article.  The 10μ or lower mist evaporates instantaneously at the contact period, thus, the molded article cools from the inner surface by the agency of a latent heat of gasification through the evaporation.

Title: Gasket
Inventor: DAIROKU NORIYUKI
IPC: F16J15/06
Filed: 1988-11-18
Abstract: PURPOSE:To reduce the reaction by a gasket and to obtain a sufficient airtight by providing a protruded part having a large curvature in the contact part of the gasket with a substance. CONSTITUTION:The face of a substance to be adhered is touched with a protruded part 2. As the protruded part 2 has a pressure receiving area smaller than other parts, a gasket 1 is easily deformed by vertical external forces. Therefore, it gives only a small reaction to the subjected pushed thereto. On the other hand, the protruded part 2 has a small contact area because of its small curvature, and even if the pushing force is small, a sufficient face pressure of the contact part can be obtained to maintain the air tight.

Thus, the reinforcing bars extending in the three directions can be connected and fixed together by use of the connectors and the fasteners. Since the reinforcing bars can be connected together without welding operations, connections can be simplified and the efficiency of reinforcing work can be enhanced. Increased connecting efficiency can also be expected.
