Ester compounds of formula are useful as monomers to form base resins for use in chemically amplified resist compositions adapted for micropatterning lithography. Although MFCW provides an estimate of the separation distance between a RF tag and the tag reader with errors that vary widely, the error values form a pattern based on the separation distance. An intermediate wall divides the guide into front and rear chambers to increase the control of media leading edges. Color control is also provided in the form of dichroic filter wheels forming cooperating adjustable low, high and band width filters including saturation control. The compensation signal has a slope profile and is initiated during each switching cycle at a set point in the cycle that is related to the switching duty cycle percentage,. MOS transistors are placed between the power supply lines in such a position that the principal axis direction of the gate pattern is orthogonal to the two aforementioned wirings, and are closely arrayed in the longitudinal direction of the power supply lines.
