Abstract: A small steam generator uses a cylindrical steam generation vessel having a steam generation portion formed to store an amount of water for generating steam and a steam passage portion formed on the upper end of the steam generation portion for spouting steam generated in the steam generation portion. A heater element is disposed within the steam generation vessel, and an induction heating coil is wound around the periphery of the steam generation vessel for energizing the heater element. The heater element is energized by supply of electric power to the heating coil so that steam generated by boiling of the water in the steam generation portion spouts upward from the steam passage.

Abstract: The subject of the present invention is to provide a steam generator constructed small in size. A steam generator 20 of the present invention is composed of a cylindrical steam generation vessel 30 having a steam generation portion 31 formed to store an amount of water for generating steam and a steam passage 32 formed on the upper end of the steam generation portion for spouting steam generated in the steam generation portion, a heater element 40 disposed within the steam generation vessel 30, and an induction heating coil wound around the periphery of the steam generation vessel 30 for energizing the heater element. The heater element 40 is energized by supply of electric power to the heating coil so that steam generated by boiling of the water in the steam generation portion spouts upward from the steam passage.

Abstract: A search technique having enhanced ease-of-use is provided. A search server analyzes web contents, extracts index information (e.g., time, geographical name, personal name, and business type), and registers the index information in an index information database. A time information search unit performs search using time as a key, a geographical name information search unit performs search using a geographical name as a key, a personal name information search unit performs search using a personal name as a key, a business type information search unit performs search using a business type as a key, and a topic information search unit performs search using a topic as a key. In order to perform narrowing down search while using these search engines integrally, a federated search unit provides a user interface to specify combined search conditions for the search engines.
