Prior to transfer of an wafer W, a mixed gas is being generated and exhausted, thereby fluctuation of concentration and temperature of a solvent component at the beginning of gas introduction into a chamber 3 is suppressed. The thermal characteristics of a home are determined based on variables such as inside temperatures, outside temperatures, setpoint temperatures, and duty cycles over time. A sleeve capable of isolating or communicating the one or more ports with an ID of the tubular. The receiver’s position has been linear-approximated by using the estimation results of the passed receiver’s positions. When the high-accuracy timer counts the time period and produces OV, demodulation operation by a rake demodulation, demultiplexing, and descrambler units is started and is continued during the reception time. In one embodiment, the second set of data may include a video stream viewable by a user.
