Abstract: PURPOSE: To prevent malfunction of mode discrimination at a weak electric field, by providing a means detecting the presence/absence of carrier wave of a sub-channel signal, in an audio multiplex broadcast.  
     CONSTITUTION: An audio composite signal is applied to input terminals T 20  and T 30  of a sub-carrier wave detection circuit 80. When an audio sub-carrier wave is detected, a voltage level at a terminal P 80  is higher, and if not detected, the voltage level is lower. A carrier control signal in the audio multiplex composite signal is applied to a pilot signal detection circuit 10, a limiter circuit 20, and a phase comparison circuit 30 from a terminal T 10 . The circuit 10, a constant current circuit 50 and a Schmitt trigger circuit 60 constitute a PLL circuit, and the output of the circuit 30 is compared at a voltage comparison circuit 70 to discriminate bilingual broadcast and stereo broadcast. The output of circuits 70 and 80 is applied to a mode discriminating circuit 90, and the mode discrimination is made with logical operation by the circuit 90.

Filed: 1987-03-03
Abstract: PURPOSE:To ensure the discrimination with a white level by controlling a discharge time constant of a charge/discharge circuit charging and discharging a peak value of an output of an image sensor based on its output even when a wide black picture signal is inputted. CONSTITUTION:A differential amplifier circuit 2 takes a difference between a white level being an output of a charge/discharge circuit 1 and a picture signal and amplifies the difference to a required level. A comparator circuit 3 compares the difference output with a slice level and when the difference exceeds the slice level, a low output is outputted and when the difference is lower than the slice level, a high output is outputted. While an output of the comparator circuit 3 is high, a switch circuit 4 decreases the discharge time constant of the charge/discharge circuit 1 and when the output is low conversely, the discharge time constant is increased.

Title: Detecting method of positions of wafer and mask
Inventor: YONEYAMA YOSHIHIRO
IPC: H01L21/30
Filed: 1984-03-16
Abstract: PURPOSE:To improve accuracy by providing a shutter means selectively interrupting a wafer-position detecting optical path and a mask-position detecting optical path, detecting the position of a wafer and the position of a mask while the points of time are made to differ mutually and synthesizing a wafer-position detecting signal a mask-position detecting signal. CONSTITUTION:Parallel beams projected to a mask 3 or a wafer 1 are reflected by rectilinear zone targets 2,4 in the mask 3 and the wafer 1 to generate Fresnel diffraction, and focussed to focal points 6,5. Since beam reflected by the rectilinear zone target 2 in the wafer 1 progress long an optical path 10 and beams refelected by the rectilinear zone target 4 in the mask 3 progress along an optical path 11, only detecting beams of the wafer 1 can be image-formed on a sensor 9 when a shutter 12 is mounted and the mask optical path 11 is interrupted. When the wafer optical path 10 is interrupted by a shutter 13, on the contrary, only detecting beams of the mask 3 can be image-formed on the sensor 9. When both a wafer-position detecting signal and a mask-position detecting signal are inputted to an arithmetical means and synthesized arithmetically, the positions of the mask and the wafer can be detected in high contrast without being affected by the disturbance of signal wave-forms resulting from simultaneous detection.
