A composite antenna is formed by combining a circularly-polarized-wave antenna and a vertically-polarized-wave antenna, is suitable for thin and small structure. The embedded conductive layer is electrically insulated from the gate electrode and the sourcedrain regions of the transistor. The comparison also results in the expected times being updated for future uses of the clothes dryer. The stationary shaft is provided with an inner hollow space for guiding the coolant. The temperature of each of the regions of the thermal plate is set based on each of the calculated temperature correction values.
