Abstract: A method for manufacturing multilayer foam where easy generation of dead air and improvement in foam magnification is offered. Multilayer resin that has non-foam layer outside foam layer is pushed out, the innermost side of the multilayer resin is bonded mutually, and multilayer resin laminating body is formed. Multilayer resin laminating body is clamped in the empty space between outermost side of multilayer resin laminating body and cavity side with metal mold. Multilayer resin laminating body is molded in the shape along cavity side, and the multilayer foam is molded.

Abstract: The method and system for retrieving information allow the user to retrieve desired information from database systems by simply specifying retrieval content and retrieval conditions using languages familiar to the user, without having to know the names for the relevant database systems or their structures or without having to interact with the platform of the meta-information, i.e., information concerning the use of database systems and accessing method. The present method allows retrieval of information from different database systems connected to a communication network, by using reference information stored beforehand to access different database systems; consulting the reference information to determine database systems which contains data to satisfy the information retrieval request by converting requested items to equivalent related words that the system can recognize.
