The rotary detector according to this invention comprises a rotary detector unit C1, C1\u2032 which detects rotary motion of a rotor; and a rotary calculator unit C2, C2\u2032, C2\u2033 comprising a rotation angle detector, which detects the rotation angle of the rotor, and an angle speed detector 47 which detects the angle speed of the rotor, based on the output of the rotary detector unit. The material is then fan-folded or formed into rolls for storage and shipment. A continuously variable power source is in communication with the power conversion device via an intermediate power-transfer connection. Additional threads create additional local memory mappings into the effective address space. 1 to 100 nm; the process uses a hydrophilic substrate or makes the surface thereof hydrophilic, then forms a film containing the composition on the surface, then forms said water repellent film by irradiating light on a part of the film surface to cure the composition and then removes an uncured composition present thereon in order to expose the hydrophilic surface. A selector selects M drive circuits having a predetermined output voltage accuracy from the drive circuits, supplies M display voltages to inputs of the selected M drive circuits, and outputs, as M drive voltages, outputs of the selected M drive circuits.
