IPC: C21C7/00
Filed: 1980-03-14
Abstract: PURPOSE:To enable to decarburize stainless steel while suppressing the oxidation of Cr in said stainless steel by blowing a gaseous mixture of O2 and Ar mixed in a specific ratio, into the molten stainless steel by using lances. CONSTITUTION:At the time of decarburizing and refining stainless steel in an arc furnace 10, one or plural pieces of lances 9 are immersed into molten metal 12, and O2 and Ar are introduced from an oxygen source 1 and an Ar source 2 respectively via reducing valves 3, flow rate control valves 4 and flow rate meters 5, into a mixer 6, whereby they are mixed in such a manner that an O2/Ar ratio attains about 0.25. Said gaseous mixture of O2 and Ar is blown into the molten steel 12 at 6Nm<3>/min flow rate per lance, so that the content of C in the molten steel 12 is decarburized down to around 0.02%. At this time, the temp. of the molten steel 12 is relatively low as 1,720-1,760 deg.C, and this decreases erosion of the refractory materials of the arc furnace: in addition, despite the low temperature, the amount at which Cr in the molten steel 12 is oxidized to Cr2O3 and turns to slag is extremely small, and there is virtually no need of treatment for the reduction of Cr2O3.

Title: Oscillator
Inventor: KOYANAGI MIYUKI
IPC: H03K3/02
Filed: 1997-02-17
Abstract: PROBLEM TO BE SOLVED: To allow the oscillator to be oscillated at a period which is not the same as that of an external periodic signal but with a relation or to allow the oscillated frequency of the oscillator to be slowly restored in self-regulatory manner in the inside by generating a signal whose period is equal to a time interval between sequentially consecutive timing signals, whose state variable is reset to an initial value. SOLUTION: A signal input means 11 receives a pulse train signal consisting of a plurality of sequentially consecutive pulses, and a state variable generating means 12 generates a state variable that is monotonously changed as time elapses. A state variable transition means 13 transits each input pulse to a value changed by a prescribed amount in a direction of a change in a state variable generated by the state variable generating means 12. A state variable reset means 14 compares a current state variable with a prescribed threshold level and resets a state variable generated by the state variable generating means 12 to a prescribed initial value, when the current value reaches the threshold level. Then a signal-generating means 15 generates a signal, whose period is a time interval between sequentially consecutive timing signals whose state value, is reset to an initial value.
