Filed: 1982-12-07
Abstract: PURPOSE:To reduce the cost and to realize the high reliability of a system by providing additionally a circuit increasing gradually an application level of a pilot signal to a coupling circuit of a terminal equipment in a multi-relaying communication system. CONSTITUTION:Additional circuits 14-16 are inserted between a pilot signal generator and a pilot coupling circuit at the transmission side of a terminal equipment, and each repeater is not provided with a level detector, a resistor and a switch and the like. When the pilot signal is restored after being interrupted, the pilot signal via a hybrid 12, an amplifier 14 and a detector 15 is subjected to delay at a delay circuit 16 by a time sufficiently longer than the response time of a thermister of each repeater. The forward current of a diode D of a variable attenuator 13 is increased gradually by an output of the delay circuit 16 via chokes L1, L2, a forward resistance of the diode D is decreased gradually, the loss in the variable attenuator 13 is decreased gradually and the pilot signal is increased gradually. Thus, the gain in each repeater is decreased gradually and the system reaches the normal state without oscillation.

Filed: 1993-08-30
Abstract: PURPOSE:To provide a joint part with sufficient strength over all the area in the plate width direction by making a preceding billet and a succeeding billet oppose each other with a gap provided between them, pressurizing both billets with a coil for induction heating with a dummy plate applied in the vicinity of a billet edge. CONSTITUTION:The rear tip part of a preceding billet 1 and the rear tip part of a succeeding billet 2, are held, pressed, and supported by clamps 3 with a gap (g) provided between them. A dummy plate 4 is pushed on both width tips in the vicinity of at least one side billet tip part. By using coils 5a and 5b for heating and holding respective billets 1 and 2, the billets 1 and 2 are heated to rise a temperature by applying an alternate magnetic field piercing them in the thickness direction of the billets 1 and 2. At the same time, both billets 1 and 2 are joined by pressurizing or they are joined by pressurizing after an objective temperature is attained. Consequently, at the time of executing induction heating, the corner part of the billet, can be heated at a heating rate the same as that in the areas to be joined except the corner part.
