A reduction of a resistance of a bit line of a memory cell array and a reduction of a forming area of the memory cell array are planed. Each propulsion member is carried by a rear portion of the fuselage. Ends of the screen are inserted between the walls of two rectangular containers which rotate on the shaft and loosely embrace the platform. A first tape is coupled to the second side edge portion of the stack of the electrode assembly, and a second tape covers a part of the bottom surface and a part of the side surface of the wound structure of the stack in a manner that the second tape does not overlap the first tape. The machine may also include suitable means for holding the cable in tension between pulling strokes, such as a pivoting wedge mechanism as described hereafter. The polarization direction of the polarizing plate and the orientation for the liquid crystal element are selectively chosen with respect to the rotation of the optical low pass filter elements in order to achieve a desired improvement in the device performance.
