The automatic completion of composite characters is supported by the generation of lists of candidate words or characters. The dual-bit memory cell has a first bit storage node and a second bit storage node near the first terminal and the second terminal respectively. The metallic base layer comprising the circuit pattern can be physically separated from the remainder of the metallic base layer on the non-conductive substrate. Both sides of the round stick type chain are connected to a piston within the cylinder on the frame and to a tension adjustment nut on the connector, respectively.
