A coordinate position detecting apparatus includes: a scanning unit that scans a predetermined scanning area in predetermined scanning precision along a horizontal direction and a vertical direction with respect to a display screen by employing detection beams respectively. A semiconductor device 100 includes a semiconductor chip 102 provided on a lead frame 121, which are encapsulated with an encapsulating resin 115. A lighting system is configured to illuminate a selected symbol on at least one spinning mechanical reels. Calibration data is then produced for the microphone as a function of a difference between each of the baseline sound-pressure-level readings and a corresponding one of each of the generated sound pressure level readings for each of the frequency banded noise samples. The absorption coefficient k at the working wavelength for the subsequent application is then obtained preferably from the scaled surface integral value for the damage induced by the energetic radiation and a calibration curve relating the absorption coefficient at the working wavelength to the surface integral of the absorption coefficient induced by the energetic radiation. Doping of the substrate for the electric field drift region is limited to a region substantially corresponding to a distance between the gate and an electrode of the capacitor.
