Abstract: PURPOSE:To constitute a circuit which does not influence the bias design of other circuit by being connected to it, and has the operation of a balanced conversion circuit in addition to that of a switching circuit, and is of less number of parts by using a signal switching FET between the drain and the source of which no current flows. CONSTITUTION:The signal switching FETs 13, 14 and capacitors 15,16 are connected to the input terminals 1, 2 of a ditterential amplifier respectively. When a control voltage is impressed to terminals 6 and 7 so as to turn on the FET 13 and the FET 14 to turn off, the high frequency signal inputted from the terminal 1 is grounded by the FET 13 and the capacitor 15, and the high frequency signal inputted from the terminal 2 is impressed to the FET 9, and is balanced converted by a constant current source 12, and is outputted to output terminals 3, 4. A current to flow in the FETs 13, 14 is only a gate leakage current by a bias between a gate and a drain, and current consumption can be neglected compared with other circuit, and does not exercies influence upon the bias of the circuit. Thus, the circuit comes to be the circuit provided with both the operation to switch the unbalanced signals of two systems and the operation as capacity for balanced-converting the inputted unbalanced signal, and the number of parts is reduced.

Abstract: PURPOSE:To prevent vertical displacement of a carrier so as to make it comfortable to ride in the carrier and to enhance the speed at which the carrier is moved by pivotally attaching a pulley to the lower end of each supporting member mounted at predetermined intervals on a support cable hanged between stanchions, and using the pulley to support a support cable from which the carrier is hanged. CONSTITUTION:C-shaped supporting members 5 are mounted at an interval of e.g. 5 to 10m by bolts and clamps, etc., on a support cable 1 hanged between stanchions 6 and a pulley (cable wheel) 3 is mounted on the end of each supporting member 5.
