摘要： In a method for allowing a cutter blade to relatively travel along an outer periphery of a semiconductor wafer to cut a protective tape joined to a surface of the semiconductor wafer in conformity with an outer shape of the semiconductor wafer, the cutter blade is allowed to relatively travel along the outer periphery of the semiconductor wafer with a positioning notch provided on the outer periphery thereof. The cutter blade is rotationally turned at the fore half of the notch recessed on the outer periphery of the semiconductor wafer during the relative travel of the cutter blade in such a manner that its blade tip is directed toward the center of the wafer. In contrast, the cutter blade is rotationally turned at the rear half of the notch in such a manner that its blade tip is directed toward the outer periphery of the semiconductor wafer.

摘要： In accordance with a length of a pit to be recorded, a laser power irradiation time is controlled to have a length of (n−K)T +&Dgr;3T, where nT represents the length of a pit to be formed, K is a constant and &Dgr;3T represents an extra laser power value for addition to recording of a 3T pit. The control section also performs control for imparting an additional top power pulse to an initial part of each pit-forming laser power irradiation so as to increase a level of the laser power over a standard recording power level temporarily for a predetermined time period during the irradiation. The K and &Dgr;3T values and the level of the additional top power pulse are optimized for each selected recording speed. This arrangement always achieves optimum reproductive characteristics of signals recorded on cyanine-based or phthalocyanine-based optical disks at any selected recording speeds.

摘要： In converting a staircase waveform signal into a smoothed analog signal, this circuit can perform the high-quality conversion without any sophisticated lowpass filter. An input staircase signal is delayed for one stepping interval to produce a differential signal which represents a stepping height at each step, by taking the difference between the input staircase signal and the one stepping interval delayed version thereof. The differential signal is integrated at every stepping interval. The integrated voltage forms a sawtooth wave signal which is in turn additively combined with the one stepping interval delayed version of the input staircase signal. The resulted combined signal is a smoothed signal of the input staircase signal.
