The invention relates to compounds of the formula Iin which the radicals are defined as specified, and also to their physiologically tolerated salts. The novel organic semiconductor compound including thiazole has liquid crystallinity and excellent thermal stability, and thus is provided to form an organic semiconductor layer in the organic thin film transistor. The system does not store information on the tokens and instead maintains access control data. Moreover, when the component assembly in which the multiple capacitors are embedded is built in the built-in-component substrate, electrode pads of the component assembly in which the multiple capacitors are embedded can be electrically connected to wiring layers of the built-in-component substrate by soldering despite the variation in height among the capacitors. By introducing the concept of density into labeled treemap, the present invention ensures the area of region occupied by each leaf node in the constructed labeled treemap is approximately corresponding to the weight of the node, and avoids the case of invisible leaf node in a treemap. A first transmitter may be used to transmit near field hearing aid signals through the near field communications antenna.
