A power transmission belt having a body with a length, a width between laterally spaced sides, and a thickness between inside and outside surfaces. A scanning line driving circuit is formed in each of the first and second panels. Normally the second substrate is a transparent substrate. The DSP chip and the CIS chip may be electrically connected to the substrate by wire bonding. The ultrasonic surgical instrument cuts or shaves hard tissues.
