The invention prevents disconnection of data lines that traverse two-layered gate lines via an insulating film. The compounds of the current invention also are potent inhibitors of human cellular proliferation. In this step, polishing is performed so as to maintain the maximum diameter of the crest on the upper corrugating roll as much as possible. The cache data structure stores the result value of the computation node. The medium detecting device includes a sensor adapted to detect magnetism of a medium being transferred; and a pressing unit adapted to press the medium toward the sensor, and the pressing unit includes at least one supporting part including a plurality of supporters to press the medium toward the sensor; and an elastic member adapted to elastically support the supporting part. As a consequence, the molding compound is removed so that the circuit element in the package is substantially exposed.
