This paper reports a mental mechanism and the characteristics for human intentional activities as applied to trans-disciplinary activities. The elementary knowledge is a pair of a parent concept and its children concept as expressed by natural language, and the mechanism is repetitive hierarchical decompositions using the knowledge. Thus accumulating knowledge, Homo sapiens built up early culture and technology. Use of this common structure enables trans-disciplinary operations, which invites industrial prosperity.
