Integrated circuit inductors achieve high quality factors by replacing a single conductive strand having a first cross-sectional area with a plurality of conductive strands having a combined second cross-sectional area that is smaller than the first cross-sectional area and a combined periphery that is greater than a periphery of the single conductive strand. The carriage is returned to a home position when opening of the exterior cover is detected. The valve impact type dispensing pump can dispense an accurate amount of a liquid at high speed. The other power unit has a worm which can drive an arcuate teeth arrangement disposed between the second moving platform and the third moving platform to drive the third moving platform rotating. When the fingerprint is taken on a curved surface of an object, the digitised mage is transformed into a plane-projection corrected digitised image, by means of an algorithm, in which the characteristic points are detected.
