A tire including a circular tire frame formed of a material containing a resin, the material including a seaisland structure including a sea phase constituted by a first resin material and an island phase constituted by a second resin material that is softer than the sea phase. A computer for this purpose may be a user or host computer, or be built in to the printer. A recording and analysis engine is adapted to record and analyze the results of the denatured attack. When the intermediate result data units stored in the external memory are needed during a subsequent internal data processing a data signal is read from the external memory. Each CODD is simple in construction and is of such a nature that it can be positioned at the desired location without any preparation having to be done. The present invention solves the problem by providing a composite active material comprising an active material, a coat layer with an average thickness of less than 100 nm, formed on a surface of the active material and composed of an ion conductive oxide, and carbon particles penetrating the coat layer, formed on a surface of the active material.
