摘要： A static electricity measuring system including a probe, a measuring device, and a calibration device. The probe includes a sensor which detects an electric field and outputs signals representing the detected electric field. The measuring device measures static electricity on the basis of the signals output from the sensor. The calibration device generates a reference electric field. The measuring device is adjusted when the sensor detects the reference electric field produced by the calibration device.

摘要： A television synchronizing signal processing circuit includes a reproduction/demodulation circuit for repetitively reading a video signal corresponding to one field from a video signal recording medium and demodulating the video signal and for separating a synchronizing signal from a reproduced/demodulated signal, a first delay circuit for permitting the video signal of the reproduced/demodulated signal which is supplied for every other field from the reproduction/demodulation circuit to be delayed by a time corresponding to one half the period H of a horizontal synchronizing signal, a second delay circuit for delaying a vertical synchronizing signal of the synchronizing signal which is supplied from the reproduction/demodulation circuit, and a waveform synthesizing circuit for synthesizing output signals from the first and second delay circuits to produce a composite video signal. In the processing circuit, the second delay circuit has a variable time TD which is variable within a range of0
