摘要： An antenna device is composed of a plurality of units of a same structure connected in series. Each of these units includes a single antenna, a level signal generating part for generating a level signal indicative of the intensity of a received signal, or that of its carrier wave, from the antenna, a demodulated signal generating part for generating a demodulated signal by demodulating a received signal from the antenna, a level signal input terminal for receiving an inputted level signal from outside, a demodulated signal input terminal for receiving an inputted demodulated signal from outside, and a selector which serves to compare the level signal generated by the level signal generating part and the inputted level signal received through the level signal input terminal, to select the level signal generated by the level signal generating part and the demodulated signal generated by the demodulated signal generating part if the level signal generated by the level signal generating part is greater than the inputted level signal, to select the inputted level signal and the inputted demodulated signal if the inputted level signal is greater than the level signal generated by the level signal generating part, and to output the selected level signal and the selected demodulated signal through a level signal output terminal and a demodulated signal output terminal, respectively.

摘要： A supervisory circuit for optical repeaters has a selective decoder circuit for selecting and decoding either one of control signals for monitoring which are separated from individual transmission signals being propagated over the first channel and the second channel. When noise ascribable to a fault occurs on the first channel, a signal path connecting to the selective decoder circuit for inputting a control signal from the first channel is interrupted. Noise of this kind is detected in terms of an input signal level which does not lie in the frequency band of control signals.

摘要： The operating device includes a first holder that holds a zoom lever so as to be rotatable, a return spring that energizes the zoom lever in the rotation direction, and a second holder that holds the return spring and is held within the zoom lever, wherein the first holder supports the return spring while causing the return spring to undergo elastic deformation. Such a configuration makes it possible to distribute the load placed on the stopper during operation, thereby preventing an operating member or the stopper from breaking.
