Provided is a semiconductor device in which the trade-off between the withstand voltage and the on-resistance is improved and the performance is increased. By applying to the infected area the cleaner dissolved the oil from the poison and absorbs it in the cloth to be disposed of. When the shaft is received in the yoke portions, the bush is inserted into through holes of the yoke portions such that the bush is positioned on a recess of the input shaft. The head has a first bristle holder with a plurality of bristles disposed therein and a second bristle holder having a plurality of bristles disposed therein. A supporting mechanism supports the print head, presses the print head against the platen roller and allows the platen roller to move the head body portion in such a direction that a contact position of the head body portion with respect to the platen roller is shifted while maintaining the head body portion pressed against the platen roller. In response to the signal, the transmitting node is operable to dynamically adjust a distribution of traffic through a respective primary path and a respective backup path from the transmitting node to the receiving node.
