Abstract: PURPOSE:To prevent the longitudinal crack by giving the alternating fluid in the right and the left directions in the rotating direction to molten steel on the interface of the solidification in a mold. CONSTITUTION:The molten steel is poured into the mold 2 from an immersion nozzle 4. Discharged flow 3 is generated at the surfaces (a), (b), (c), (d) of a cast slab, To an electromagnetic stirring flow 5 in the mold, at the surfaces (a), (c) of the cast slab, a reversing flow of the discharging flow coincides with the stirring flow in the direction and the flow speed at the interface of the solidification can be secured, but at the surfaces (b), (d) of the cast slab, the reversing flow 3 of the discharging flow is cancelled with the stirring flow 5 and the flow speed at the interface of the solidification can not be secured. Then, as the result, in which the rotating direction of the molten metal fluid at the interface of the solidification is alternated in the right and the left directions with the electromagnetic stirring device 1 in the mold, the longitudinal crack on the whole surfaces (a), (b), (c), (d) of the cast slab can be prevented, and the saving of repairing and the improvement of productivity can be obtd.

Title: Analog-digital converter
Inventor: TANAKA MASATO
IPC: H03M1/50
Filed: 1985-08-09
Abstract: PURPOSE:To lower a clock frequency to a required minimum value by controlling a threshold voltage of a comparator circuit in response to the pulse number so as to save the number of adjusting sections. CONSTITUTION:When an input value to a comparator circuit 51 is smaller than a threshold value theta2 becaus number of clock s inputted to a low-order counter 14 up to the end of A/D conversion s zero or small, an up-down counter 52 counts down a conversion clock from a terminal 23. Thus, coarse adjustment is applied at a variable delay circuit 30 to decrease the delay and a reference voltage is changed by the output of a D/A converter 40 to apply fine adjustment. When the input value of the comparator circuit 51 is between threshold values theta1 and theta2, the output count value of the up-down counter 52 is held and only the number of clocks within one cyclic count operation or over is counted by the low-order counter 14 to decrease the A/D conversion time.
