An integrated circuit having an array of APS cells. The insulin derivatives of the invention are, in one aspect, suitable for delivery to the lung and exhibit pharmakokinetic andor pharmacodynamic properties that are significantly improved over native insulin. The assistance amount setting unit obtains a generator-motor assistance amount in accordance with the deviation. Through this measure, the frequency characteristic can be optimally influenced to suppress noise. The masses of conductive material may be formed into columnar members wherein the columnar members are skewed when formed between a pair of relatively offset contact pads. The expending member includes an aperture, a nut, a plurality of expansion sheets vertically extending around an outer wall thereof and surrounding around the actuation post, and a resilient loop fitted on a distal end thereof.
