A semiconductor device includes an identification information generation circuit having a power supply control circuit whose output voltage is controlled by a control signal, and a memory array having a first cell power line and a second cell power line. The apparatus further includes an engine section which forms the image in accordance with the outputted image data. A plurality of water transport pores are defined through the sheet. In addition, a photonic switch is formed so that a gate signal is applied in a direction that is substantially perpendicular to the direction of the input signal so that there is no effective contamination of the input signal by the gate signal affecting the output signal. The coating 1b is removed without damaging the surface of the optical fiber. A floor wherein the separator is raised to form a hump adjacent to or in which the opening is located.
