An image-forming-device management system includes an image-forming-device, a data communication device and a central management device. The first step is performed using H2O2NH4OH solution, and is stopped before the thin film resistor material is exposed. s, when the shear rate is 1 s\u22121. The anamorphic lens group may be mounted on structure that allows it to be removed from the central beam path. The controller includes a power management unit configured to control a power state of the position location unit and the simplex satellite transmitter, and to periodically enable and disable power from the power source to the position location unit and the simplex satellite transmitter. When the SOI substrate is fabricated by using a technique typified by SIMOX, ELTRAN, or Smart-Cut, a single crystal semiconductor substrate having a main surface of a {110} plane is used.
