Title: External synchronizing system
Inventor: MIMURA KAZUHIRO
IPC: H04N9/44
Filed: 1982-03-15
Abstract: PURPOSE:To eliminate noise from a screen, by rising a horizontal oscillating circuit of a pickup section at a tail or a front edge of an external drive pulse, performing oscillation having a wide pulse and operating the circuit so as to  form the oscillation stop period to be a blanking period. CONSTITUTION:The horizontal oscillation is started at the tail edge of a drive signal pulse, continues the oscillation for the horizontal scanning period, and the oscillation waveform making the oscillation stop period as the blanking period is obtained. Thus, the synchronizing signal of the input waveform of the oscillation section 1 is in the blanking period, then the effect on the TV screen is eliminated completely even if noise component is left in the output waveform and the  erase of the synchronizing burst signal is incomplete.

Abstract: PURPOSE:To automatically synchronizing transmission and reception with each other by superposing a synchronizing signal in the beginning of the generation of a modulated signal, regenerating the synchronizing signal from the signal after the demodulation of the projection light of a reference fiber, and outputting the demodulated signal selectively. CONSTITUTION:The synchronizing signal from a synchronizing signal generation part 22 for a specific time in the beginning of the generation 24 of respective modulated signals (f1-f4) and the superposed signals are sent to a light signal sensing means 25. The sensing means 25 imposes intensity modulation upon a reference light source 281 and measurement light sources 282-284 in order and their light beams are made incident on the reference fiber 61 and a fiber 62 to be measured.
