In an image control system, with a reactive force on an input device that controls a pointer in a display, a bilateral communication of a pointing device can prevent a sense of discomfort while the system is used by an operator. The tip electrode pin engages an inner conductor coil at a proximal end and engages a proximal end of the helical anchor electrode at a distal end. The memory blocks and the control logic blocks are configured to emulate a plurality of memory types. The method further includes forming a control gate by anisotropically etching the second semiconductor layer and then subsequently isotropically etching the second semiconductor layer. In order to achieve a structurally compact construction which enables favorable transmission ratios the rotor outputs to the drive element of the differential and that by interposing a gear mechanism, the drive element andor the output shafts are supported offset to the rotation axis of the rotor. Then, the planes are registered with each other, as are the points, to obtain registered primitives.
