    摘要: A method of degassing and decarburizing molten stainless steel in a vacuum, which molten steel is produced in a steel making furnace. Molten steel is foamed in a vacuum tank. Before foaming the [N] (%) in the molten steel is increased. The foam is produced by denitrification of the steel during vacuum degassing. Oxidizing gas is blown through a top-blow lance onto the surface of the steel in a vacuum tank, causing the reaction C+1/2O.sub.2 .fwdarw.CO to decarbonize the steel. Temperature decrease of the molten steel is resisted by combustion of CO produced by the reaction of C+1/2O.sub.2 .fwdarw.CO.

    摘要: A method of driving an ink jet recording head and discharging ink during a preliminary discharge process comprises discharging liquid from less than all of a plurality of discharge units during a discharge stabilizing process. In a specific embodiment, during the discharge stabilizing process liquid is discharged from discharge units selected from a plurality of discharge units prior to recording to rid the liquid passages associated with the discharge units of ink which has increased in viscosity.

    摘要: A pressureless sintered body of boron nitride contains more than 95 wt% of boron nitride. The pressureless sintered body hexagonal of boron nitride has a density of not less than 1.10 g/cm.sup.3 and a bending strength of not less than 300 kg/cm.sup.2. A process of producing the pressureless sintered body of boron nitride comprises pulverizing powders of starting feed boron nitride so that a specific surface area of each of the powders is two times or more than that of the starting feed boron nitride powder, molding the thus pulverized powders to obtain a pre-molded body and sintering the pre-molded body at a temperature of not less than 1400.degree. C. under atmospheric pressure and under non-oxidative atmosphere.

    摘要: A process of degassing and decarbonizing is directed to a process for performing vacuum degassing non-deoxidized or slightly deoxidized molten steel utilizing RH process or DH process. The process includes blowing of oxygen or oxygen containing gas toward the surface of the molten steel in a vacuum chamber for promoting decarbonizing reaction. The process further includes a step of combustioning of CO gas in the vicinity of the surface of the molten metal at a timing, in which concentration of (CO+CO.sub.2) in an exhaust gas is higher than or equal to 5% and a ratio of CO.sub.2 versus (CO+CO.sub.2) in the exhaust gas is approximately 30%. Heat generated by combustioning of CO gas is utilized for compensating temperature drop of the molten steel.
