Abstract: A crashworthiness energy absorption part includes: a tubular member having tensile strength of 590 to 1180 MPa grade; a closed cross section space forming wall part having tensile strength lower than the tubular member and having both edge portions joined to inner surfaces of a pair of side wall portions of the tubular member, and forming a closed cross section space between the closed cross section space forming wall part and a part of a peripheral wall portion of the tubular member; and a resin configured to fill the closed cross section space, includes a rubber-modified epoxy resin and a curing agent, and has tensile breaking elongation of 80% or more, adhesive strength to the tubular member and closed cross section space forming wall part of 12 MPa or higher, and a compression nominal stress of 6 MPa or higher at a compression nominal strain of 10%.

Abstract: A new conversion database associated with information to be finally stored in a host information database is stored in a RAM along with a previous conversion database. Each processing unit refers to the new conversion database to identify data to be held in the host information database of the processing unit itself and refers to the previous conversion database to identify the processing unit which currently holds the data thus identified. The processing unit further relocates the data to be held in the processing unit itself from the processing unit thus identified.

Abstract: A plurality of database hosts hold subscriber information in a distributed manner. A retrieval server processes inquires (host retrieval requests) on which of the database hosts has desired subscriber information stored therein. The retrieval server includes a plurality of processors, and the plurality of processors performs processing in parallel. Therefore, inquiries can be processed at a high speed. Further, a conversion information database and a host information database are provided as in-memory databases, which allow inquiry processes to be processed at a high speed. A call control server can efficiently acquire subscriber information from the database host based on the result of an inquiry made to the retrieval server.
