When the signal S is ''L'' and the signal R is ''H'', the output Q always outputs an ''L'' level signal, and when a latch signal LA is turned to ''H'', it outputs the inversion signal of the signal D. When the signals S, R are both ''H'', the outputs Q, Q' are both ''L'' independently of a signal LA. Therefore, the priority is R, S and LA in the output Q and S, LA and R in the output Q'.

This compacting operation is executed under conditions of >=500 deg.C surface temp. of the mixed raw material or >=80% generating ratio of the volatile matter in the mixed raw material and <=60% reducing ratio of the mixed raw material. The surface temp. of the mixed raw material is desirably at >=800 deg.C and in this method, the generating ratio of the volatile matter becomes 100%. Further, when the reducing ratio of the mixed raw material exceeds 60%, since the mixed raw material is sintered and the compacting operation becomes difficult, this ratio is desirably <=50%.
