Filed: 1990-02-09
Abstract: PURPOSE:To prevent a fault owing to an overvoltage and an overcurrent in a telephone system and a telephone exchange system connected to the system by detecting an excessive feed current from a telephone line or the like and interrupting the feed current at a moment when a telephone set is off-hooked at the time of connecting a system to the telephone exchange system or the like different in an electric interface. CONSTITUTION:When an operator off-hooks the telephone set for calling, a telephone line 28 and a call circuit 16 are connected and a control circuit 14 and the call circuit 16 are fed from the telephone line 28. When the feed current exceeds the allowable value of the call circuit 16, a detection circuit 22 outputs the value to the control circuit 14. The control circuit 14 transmits a control signal to a switch 12 and instantaneously controls the switch 12 to an off state if the detection circuit 22 detects the overcurrent when a hook switch 18 is in an off-hook state. Thus, the overcurrent flowing from the telephone circuit 28 to the call circuit 16 is interrupted.

Title: Insertion of linear member into pipe
Inventor: ARAKI NOBUO
IPC: H02G1/08
Filed: 1989-02-09
Abstract: PURPOSE:To insert a linear member without doing damage to the linear member and a pipe by holding the inlet end of the pipe so as to be movable in the longitudinal direction of the pipe and by inserting the linear member into the pipe by taking advantage of vibration. CONSTITUTION:A pipe coil 5 is formed by winding it around a pipe 1. Then, from the pipe coil 5 an end section of the pipe 1 is pulled out to form an inlet part 2 of the pipe. A pipe inlet end section 3 is then held so that the movement in the dismetral direction of the pipe by the pipe inlet end 3 may be restrained and movable in its longitudinal direction. When a linear member 7 is supplied to the pipe inlet end 3 and the pipe coil 5 is vibrated so as to reciprocate along the spiral route from an arbitrary point of the pipe 1, the linear member 7 inside the pipe 1 receives the force bound to diagonally upward ahead from the bottom of the inner wall of the pipe 1 and jumps diagonally upward ahead inside the pipe 1 or slidingly moves on the bottom surface of the inner wall of the pipe 1. Carrier force in the circumferential direction of the coil 5 is thus given intermittently from the inner wall of the pipe 1 to the linear member 7, with which it moves forward in the pipe 1. The linear member 7 can thereby be inserted without doing damage to the pipe 1 and to the linear member 7 itself.
