Title: Metal vacuum treatment and device
Inventor: JIYOSEFU EI MARUKEI
IPC: C21C7/10
Filed: 1985-01-17
Abstract: Molten steel or other electroconductive metal is treated with vacuum to remove dissolved gases therefrom. A rod (28) of molten steel is drawn from a bath (14) by applying vacuum to a vertical tube (22) dipping into the molten bath (14). An electrical coil (26) surrounding the tube (22) applies an intense magnetic field to the steel rod by the passage of high frequency alternating current through the coil (26). The rod (28) is compressed radially inwardly by the magnetic field exposing the whole of the external surface of the rod (28) to vacuum. At the same time, the induced eddy currents superheat the steel rod. The large surface area of application of vacuum combined with the narrow dimension through which the gas must travel ensure rapid and efficient removal of the gases. The procedure is repeated until all the steel in the bath has been treated. Lack of contact of the steel rod (28) with the tube surface eliminates loss of heat by convection and the superheating of the steel rod by the eddy currents ensures that the overall heat losses are minimal during processing of the molten metal bath.

Filed: 1990-01-12
Abstract: PURPOSE:To attain the automatic wait control via a simple circuit by starting the wait control via a microprocessor based on only the wait trigger conditions of the wait request signal received through a wait request signal terminal. CONSTITUTION:When an access request is outputted to a peripheral device 16 from a main control part 12, the trigger conditions are detected for a wait request signal and sent to a wait instruction signal generating means 14. Then a wait instruction signal is outputted to the part 12 from the means 14. Thus the bus cycle of the part 12 is kept waiting by an extent equal to the state number set by a state number setting means 13. During this wait period, the accesses are given to the part 12 and the device 16. Then the wait state is canceled after the prescribed state number and the original bus cycle is reset. Thus the automatic wait control is attained for a microprocessor in a circuit scale simplified extremely.
