The present invention relates to an information processing apparatus, a feature extraction method, a recording media, and a program that are adapted to easily and correctly extract features of classes in which a plurality of elements are classified. The method produces, in a single stage, a polyurethane foam molded article having the skin or high density portion selectively formed on portions of the molded article actually requiring them, where the proportions of the skin and the high density portion and the foamed core can be varied freely. A web server, coupled to the various astronomical hardware, processes the request on behalf of the user and responds with the status and results of the request. Afterwards, a planarized film layer covers the TFT’s and the metal layer.
