Filed: 1993-04-05
Abstract: PURPOSE:To improve reliability when a fault occurs in a control part by providing a reserve subscriber circuit as the reserve of a subscriber circuit and performing the pull-in control from the subscriber circuit to the reserve subscriber circuit. CONSTITUTION:When a fault occurs in a subscriber circuit 11, the fault is detected in a subscriber line control common part 20A of an active system and it is reported to the main body 1 of an exchange. When the exchange 1 receives the notification, it transmits a subscriber circuit switching signal to the common part 20A. Then, an MPU 21 receives this relay switching control information in the common part 20A and writes the relay information in a subscriber control memory 23. The relay RL of the circuit 11 is controlled by the output of the memory 23, the common contact of the relay RL is switched from (a) to (b), and a subscriber terminal 2 is connected with a reserve subscriber circuit 13. The MPU 21 writes the same information as the one written in the memory 23 in a RAM 22. As a result, reliability is improved because the switching state of the circuit 11 can be held when the switching to a subscriber line control part 20B of a reserve system is performed.

Abstract: PURPOSE:To obtain the uniform quality of a cast ingot scarcely having segregation at the center part by controlling the shape of unsolidified range by electromagnetic force at the time of continuously casting and uniformly executing rolling reduction to the unsolidified range. CONSTITUTION:Molten steel 2 supplied from an immersion nozzle 1 becomes discharging flow 3 toward short sides in a mold. Eddy current 5 is induced by an interaction with static magnetic field 4 impressed to this part to form a current loop. By the interaction between the induced current and the impressed magnetic field, Lorentz force 6 is acted in the reverse direction of the discharging flow to give braking force to fluid of the molten steel. In this result, the molten steel fluid pattern is controlled to the cross sectional fusiform, and in a speed distribution in the cross sectional surface of the ingot, the speed at the center part can be made at larger than the speed of both sides. To the ingot having the unsolidified range developed in such fluid condition, the rolling reduction can be executed according to this solidified shrinkage quantity.
