An accelerator solution is globally applied to a workpiece to form an accelerator film, and then a portion of the accelerator film is selectively removed from the workpiece to form an acceleration region having a higher concentration of accelerator. The circuit then generates a control signal based upon the specific frequency designated by the user. The communication tool may be run downhole and within the TRSSSV. The latch circuit receives the data signal fed in from the card interface, latches the data signal and outputs it to the data processor afterwards. According to an optical element as one aspect of the present invention, an angle between a 0 0 1 axis of an isometric crystal and an optical axis is less than 10\xb0, and preferably 0\xb0.
