An apparatus having at least one rotatable driven object having an edge on which are disposed a series of adjacent magnets of alternating polarity and a driving object rotatable by an external motor torque and having a series of adjacent magnets of alternating polarity on a magnet supporting surface. The toothbrush also contains a handle portion, which is attached to the receiving portion at the opposite side of the head portion. The plasma display device includes a power source unit for providing power with different voltage levels to the scan electrode driver for driving the scan electrodes in the reset period, the address period, and the sustain period. An initial pullup drive circuit is coupled to the plurality of output drive devices and produces an initial elevated drive voltage to the plurality of output drive devices.
