For example, the oxygen necessary for the living things is supplied by an artificial lung 6 with a breeder of a perfect hennetic type assuming cosmic experiments. The zeolite 2 and active carbon 3 are respectively mounted in a breeding tank 1 for the purpose of water purification. Further, the breeding water is supplied at a specified temp. at all times via a heat exchanger 5 by a water circulating pump 4.

Filed: 1988-01-07
Abstract: PURPOSE:To use a high speed digital private line, to use an optional station as a master station and to attain multiple address communication by applying control so that a 0 level is outputted in case of transmission and a 1 level is outputted in case of no transmission. CONSTITUTION:A receiver 2 receiving a digital signal is connected to a branch side of a branch circuit 1 for a high speed digital private line. Moreover, the output of a transmitter 3 sending a digital signal and an output of a transmission control section 4 are given to the insertion side via an OR circuit 5. Thus, an optional station A sending a signal brings the output of the control section 4 to 0 level to insert the output of the transmitter 3 to the high speed digital private line as it is via the circuit 1. Furthermore, other station not sending a signal brings the output of the control section 4 to 1 level to mask the output of the transmitter 3 and to insert 1 level to the circuit 1. Thus, the signal from the station A is branched by the circuit 1 and inputted to the receiver 2 of other station, then multiple address communication is applied.
