A transport system having multilayer tracks is presented. Both first and second magnetic layers have bcc crystalline structures, and said non-magnetic spacer layer has a film configuration in which an insulating layer or a semiconductor layer is inserted into a metal layer. Further, the vibration apparatus includes a vibration measurer for measuring vibration generated by the vibrator and providing the measured vibration values to the frequency controller. The liquid crystal of this region is also driven by the voltage same as the pixel electrode. An upper surface of the semiconductor layer in the second region is lower than an upper surface of the semiconductor layer in the first region. Reconfiguration from parallel to series, or vice versa, is obtained physical reconnection of the output stage terminals and adjustment of a single voltage feedback scaling factor.
