A method for transmitting data includes receiving at a first relay station first data from a parent station during a downlink period comprising a plurality of downlink zones. The susceptor can inhibit generation of particles resulting from plasma corrosion, and can suppress extensive leakage of gas from a space or a gap between the plate member and a substrate. A voltage induced in a high-side drive winding is applied to the high-side switching device to turn on the high-side switching device.
