Title: Automatic control shift system after roll-back
Inventor: ITO KUNIO
IPC: G06F12/00
Filed: 1990-06-18
Abstract: PURPOSE:To attain the automatic shift of control in a system right after a commit instruction which is carried out at an immediately preceding time point by restoring the contents of a stack at a relevant time point at execution of a roll-back instruction by a stack restore mechanism based on the stack contents stored at a commit time point. CONSTITUTION:At an executing time point P5, a stack is kept in a state '65'. In this case, however, an executing stack is set in a state '66' at an executing time point P6 when the contents of a stack save area are shifted to a stack area by a stack restore mechanism. Under such conditions, the stack restore mechanism returns to a module of the caller side. Thus the return address of the present stack is set right after a commit instruction contained in a main program and therefore returns to the place right after the commit instruction. As a result, the control can always be returned to a place right after the commit instruction which is carried out at an immediately preceding time point.

Title: Method for vacuum-degasifying and decarburizing molten steel
Inventor: NISHIKAWA HIROSHI
IPC: C21C7/10
Filed: 1989-06-21
Abstract: PURPOSE:To decarburize molten steel and to reduce its temp. drop by blowing gaseous oxygen against the surface of molten steel at a position of a specified distance above the bath surface, and burning gaseous CO when the concns. of CO and CO2 in the exhaust gas reach specified values. CONSTITUTION:The undeoxidized or weakly deoxidized molten steel from a steelmaking furnace is vacuum-degasified and decarburized by the RH method, DH method, etc. In this vacuum degasification method, gaseous oxygen or an oxygen-contg. gas is blown against the molten steel surface in the vacuum- degasification vessel kept at 1Torr or more, or preferably at 1-100Torr, from a position of 1.6-4.5m above the molten steel bath surface. As a result, the molten steel is decarburized. When (CO+CO2) content of the exhaust gas becomes >=5% and the ratio of CO2/(CO+CO2) becomes >= about 30%, the oxygen blowing conditions are appropriately adjusted, and the generated gaseous CO is burned in the vicinity of the molten steel surface. Consequently, the decarburization is advantageously promoted, the combustion heat of gaseous CO is transmitted to the molten steel, and a temp. drop of the molten steel due to the decarburization is reduced.
