A power device includes a gate electrode, a source electrode, and a drain electrode provided within an active region of a semiconductor substrate of first conductivity type. The display device according to the invention has two overlaid semitransparent flat display screens, one passive and the other active, each symbol displayed on the semitransparent display device comprising a first representation and a second representation. The system further includes a dispatcher operatively connected to the plurality of processors and configured to: receive a first thread to dispatch, select one of the processors to dispatch the thread to based on the processing state the processors and a power management policy, and dispatch the thread to the selected one of the plurality of processors. In addition, the deformation resistance adjusting means are formed movable forward and backward relative to the second mold.
