    摘要: An optical fiber communication system using group transmission which transmits PCM information by utilizing an optical fiber group composed of a plurality of optical fibers. The PCM information in a plurality of optical fibers is stored in a memory of the system's sending terminal, the stored information of each memory is read out by simultaneous clock pulses so as to send out the information to a transmission line which is composed of a plurality of said optical fibers. A repeater is provided in the transmission line having at least one of the following circuits, an AGC circuit, a light element control circuit, a power supply circuit and a supervisory circuit. The supervisory circuit is commonly provided for checking a plurality of signals which is transmitted by the above-mentioned optical fibers. In the repeater, the signals are regenerated by simultaneous clock pulses which are generated from one common timing circuit, and the phases of the signals are arranged in order for sending out said signals to the transmission line composed of said optical fibers.

    摘要: An optical rotary encoder having a rotatable pulse scale having a row of code pattern with specific light-permeable or-deflection slits each for outputting a reference position signal and other light-permeable or reflection slits each adapted to reduce the amount of light for outputting an angular signal, both of the optical signals being photoelectronically converted and the waveform of the resultant electric signals being shaped based on threshold voltages into electric pulse signals indicative of a reference angle of 0.degree. and the accumulated angle of rotation, in which the circumferential width of each specific reference slit is made narrower than that of other slit so that the pulse width for angular position indicating of the angular pulse signal is always equal and constant for ensuring more accurate detection of the angle of rotation.

    摘要: A vacuum-type sewage collecting apparatus is arranged in such a manner that sewage discharged from the houses or facilities is once accumulated in a cesspool, and the sewage accumulated in the cesspool is then collected through a vacuum valve and a vacuum sewage pipe, the interior of which is under a negative pressure. The vacuum valve is operated by negative pressure taken from a vacuum source and supplied to the vacuum valve via a connecting pipe. The negative pressure for operating the vacuum valve is taken from a portion of a vacuum sewage pipe which is elevated at a level higher than that of the vacuum valve and is disposed downstream of the vacuum valve. Alternatively, the negative pressure may be directly taken from an accumulating tank, the inner pressure of which has been evacuated by a vacuum pump, from a pipe which establishes a connection between the accumulating tank and the vacuum pump, or from a tank connected to the pipe connecting the accumulating tank and the vacuum pump. In this way, a high negative pressure can be supplied to the vacuum valve to effectively and completely open the vacuum valve to thereby perform an efficient discharge of the sewage through the same valve.
