Abstract: PURPOSE:To enable detection of position of a specimen accurately, by placing one against the other on both sides of a specimen a pair of light emitting elements and a pair of light receiving elements of a detector provided with a photointerrupter. CONSTITUTION:When a reticle SA is combined falsely with a holder 4, screening of pulse light is affected adversively, light-receiving quantity at a light-receiving element 6 becomes unstable, the initial position signal S1 shows an abnormal signal and a CPU10 stops to displace X, Y stage 1 from a load position. Further, when the X, Y stage 1 is located in a load position (an objective lens 8 being located directly under a servo-check plate 7), a servo-system of automatic focusing control mechanism is checked to suspend functioning of the X, Y stage because of erroneous functioning at an abnormal time. Further, the servo-check plate, even if the Z-axis stage 2 reaches its top limit, a slight clearance is left between the objective lens without damaging the objective lens and servo-check plate. Thus, a reticle inspection apparatus becomes available at a high standard of safety.

Abstract: PURPOSE:To prevent color inversion due to synchronizing dropout during reproduction by detecting the DC level of the pedestal portion of the FM demodulated chrominance signal and correcting the switching timing of a changeover switch in accordance with the detected DC level. CONSTITUTION:When the synchronizing dropout is caused as shown by dotted line in Fig. A and red chrominance signal R-Y is supplied to a blue chrominance signal processing circuit 11, since the Q output of a frequency divider 14 is low due to immediately preceding synchronizing dropout when the output C of a comparator 26 goes high by the demodulation output of the blue chrominance signal B-Y following the red chrominance signal R-Y, the output of an exclusive OR gate 27 goes high. When the switch 29 is closed by a burst gate pulse D, a clock signal E is supplied to a clock input terminal of the frequency divider 14. As a result, the high level signal so far supplied to a data input terminal of the circuit 14 is supplied as Q output to a changeover switch 9, the erroneous polarity of the switching pulse shown by the dotted line in Fig. B is inverted to prevent color inversion due to synchronizing dropout.
