A communication unit 1 carries out voice communication, and a character background selection input unit 2 selects a CG character corresponding to a communication partner. The semantic objects include text runs that are produced from the markup language representation and that are placed into semantic blocks that group text runs according to how text is logically structured in the document being represented. The invention further discloses a transmittingreceiving device and to an integrated circuit with such a detection unit and to a corresponding detection method. Users of the databases may then be presented with unique instances of data rather than product and inventory data that appears to be different but are actually duplicates of data already entered into the database. Such an ultrasonic probe is advantageous in efficiently discharging bubbles remaining in the sheath with less water flow, and also reducing the diameter of the ultrasonic probe while keeping a high quality of an ultrasonic tomogram.
