A reinforced member which is made from a steel product having a strain aging characteristic and has a closed section at a cross section perpendicular to an axis of the reinforced member. An apparatus includes an entropy decoder for respectively entropy decoding an encoded respective rank number for each of a plurality of candidate reference blocks with respect to a current block to be decoded to obtain a decoded respective rank number there for. Second and third passages are formed and extend from associated openings in the peripheral surface to associated openings in a face surface of the rotor body. The interval between the optical device and the lens is set greater than a reference interval and the focal length of the lens. Each squeegee blade may have a dedicated sheet.
