By a simple apparatus construction and process, it is made possible to clean precisely a surface at the molecularatomic level, and the purification degree of the surface processed minutely is made into 1012 moleculescm2 or less. A transmitter that is configured to process the fare request and transmit a request for fare information regarding the fare request to an airline fare information system. Portions of the filament lengths within the unitary structure are free of matrix islands, causing the domain matrix to be discontinuous. The heat from the light-emitting diode is directly conducted away through the heat dissipating piece serving as a thermal conducting medium, thereby shortening the path that heat dissipation must pass through, which increases speed and improves effectiveness of heat dissipation. One or more connector pieces are attached to certain ones of the frame brackets. The pillow body is curved and is both flexible and firm to permit it to wrap around a user.
