A system for placing an implant in the body includes an elongated member having at least one inner lumen extending from a proximal end portion of the member to an opening in a distal end portion of the member. The fixed image display further comprises at least one continuous electrode layer extending across at least two rows and two columns of the pixel matrix, and is connected to the electrolyte segments of a subset of the pixel elements. A first gear is fixed on this projection end of rotated axis. To increase the reliability of the switching function, the shield is arranged in the closed loop of the spring force flux. The nonvolatile semiconductor memory device includes a voltage control circuit which applies a select gate voltage obtained by adding the biased positive voltage to a voltage set at read time of a cell with a positive threshold voltage to a select gate at a read time and verify time for the cell with the negative threshold voltage.
