A communication node receiving andor transmitting radio communications according to a first and a second communication protocol simultaneously. The encoded data is read from the memory cells, and inner code decoding is applied to the read encoded data to produce a decoding result. During this echo train, a 90-degree RF pulse applied with proper phase at the center of any echo turns the magnetization back in the direction of the static magnetic field. The two primary winding sets are wound around the winding rack and receive low-voltage signals from the driving circuit. The light deflecting device, post-deflection optical system and the cover window portion are so disposed that the pretreated light-shielding reflection light from the cover window portion avoids from striking upon a flange portion and an edge portion of one or a plurality of the optical element parts within the post-deflection optical system, with respect the entering light. A three-dimensional CAD data rotating unit rotates the VOXEL model around one axis of the principal axes of inertia to generate the rotated VOXEL models, thereby finding the VOXEL model with the least volume error between an actual volume Vc of an analysis object calculated for a three-dimensional CAD model and a volume Vv of the VOXEL model.
