The invention relates to an electro-optic modulator structure containing an additional set of bias electrodes buried within the device for applying bias to set the operating point. The undershoot eliminator circuit functions to discharge an energy storage element in an auxiliary supply on said secondary side of said converter. When reading on DVD, the objective lens, the polarization plane rotating means and the super-resolution cut-off filter in combination are set to the optical path. The microsphere can have a diameter in the range of 20-1000 \u03bcm and can be divided into a wide variety of sizes in case of need. Prizes are subsequently awarded to each of the respondents based on their respective rankings, and a survey is conducted with respect to each respondent’s opinion of the prototype gaming machine.
