This specification describes technologies relating to imparting cryptographic information in network communications. The rotor core has a plurality of axially extending through-holes in a circumferential direction thereof to accommodate the permanent magnets and to increase circumferential magnetic reluctance thereof to form a plurality of auxiliary pole portions disposed between the through holes. The conversion step is carried out immediately after movement of the next element and is continuously repeated, and the computing step is processed in parallel with the conversation step. A candidate vector with the highest matching degree between the fingerprint images in the current and previous sensor images is selected from the candidate vectors to obtain a detected vector, and the detected vector is corrected to exclude an influence of erroneous detection and to control a movement of a pointer. Being narrower than the plate cylinder gap, no loss of print length results from the seam. During an imprint lithographic process the template may be aligned with the substrate by the use of alignment marks disposed on both the template and substrate.
