An endoscopic insertion aid includes a tube member, a pipeline and a plurality of balloons. From the surface currents flowing from the feed through the first high frequency leg and the second high frequency leg, the antenna is provided with a multiply widened high-frequency band. The thin film transistor is placed on a substrate and includes a channel region which has at least one P-type or N-type nanoparticle arranged in a lengthwise direction, wherein the lengthwise direction of the P-type or N-type nanoparticles is parallel to a P-type or an N-type nanoparticle line partitioned off on the substrate. At least one recess is formed within the signal contact assembly; and at least one protruding ridge extends from the signal contact assembly. There generates a motion deficiency in a motion amount shown by mark A and overshoot shown by B. If the emissions levels and acoustic pressures are within specification limits, then the power is increased to a different mode and bleed setting combination, and the process is again repeated.
