Title: Optical clock signal extraction circuit
Inventor: KIKUCHI NOBUHIKO
IPC: H04J3/06
Filed: 1995-10-05
Abstract: PROBLEM TO BE SOLVED: To provide a simple optical clock signal extraction circuit which is free from dependency on polarization in a very high speed optical transmission system that applies an optical time division multiplex technique. SOLUTION: The signal light that undergone the time division multiplex/ intensity modulation is multiplexed with the output light (non-modulated) of a clock light source 101 and inputted to a field absorption type optical modulator 103. The modulator 103 is driven by an electric signal of a sine wave and undergoes the phase synchronous control via a PLL control circuit 106 to maximize the intensity of the wavelength component of the signal light among the output beams. Therefore, the clock beams that passed through the modulator 103 are simultaneously turned into the short pulses and outputted. Thus a short pulse light source is not required for clocks. Furthermore, no influence is caused by fluctuation of the polarization state of the input signal light as long as a modulator which is free from dependency on polarization is used.

Abstract: PURPOSE:To be able to properly achieve the automatic operation of a ventilating fan, even if there is dispersion in the resistance value of a smoke-detecting resistance element by compensating the operating value correspondingly to the level of a reference value which is the same as the resistance value of a smoke-detecting resistance element operating in an ordinary air condition. CONSTITUTION:The resistance value of a smoke-detecting resistance element 1 which varies its resistance value responding to smoke is changed into off-time with square wave by an unstable multi-vibrator circuit 2. This wave is put in a microcomputer 4 through a wave-shape forming circuit 3. The computer 4 takes in the resistance value of the element 1 in an ordinary air condition as a reference value and when the relative value of a varied resistance value is over the set value, a motor 7 is driven to make ventilation. And, this operating value is compensated in accordance with the extent of variation in an atomosphere wherein a ventilating fan is placed.
