Abstract: PURPOSE:A dephosphorizing agent which is composed of the CaO in which a portion of grain boundaries of the fine CaO primary crystal constituting CaO are filled by amorphous C, as well as amorphous C, and which makes the slagging of CaO faster as compared with ordinary dephosphorizing agents mainly composed of CaO. CONSTITUTION:The calcareous material which is mainly composed of CaCO3 or/and Ca(OH)2 is calcined in a nonoxidative atmosphere with the supply of CO or/and organic compound gas (e.g.: CH4). The gas composition of the calcining zone in this case maintains the content of CO at 2.0 or more and the content of CH4 at 0.7 or more, respectively with respect to the O2 contained based on volume, and the nonoxidative atmosphere is maintained by the supply of the CO and the organic compound gas in excess amount with respect to the O2 contents.

Title: Timing extraction system
Inventor: KATOU YOSHIBUMI
IPC: H04L25/40
Filed: 1979-03-05
Abstract: PURPOSE:To enhance the signal quality by generating the retiming pulse within the retiming section and then repeating this operation to converge the retiming pulse to the optimum retiming phase. CONSTITUTION:The timing extraction is carried out from the base band signal which is ternary-transmitted through the base band transmission line. In this case, the detection given at the areas other than the normal changing point due to the noise or the like is prevented by malfunction preventing circuit 52. For the normal changing point thus obtained, the locus distribution of the changing point at the region of 1-symbol length is stored into memories 55 and 56 for the fixed totalizing time. The distribution result is analyzed at arithmetic circuit 57, and the retiming region is obtained within the significant information region of the input signal. And the retiming pulse is generated 510 within the retiming section. This operation is repeated in order to converge the retiming pulse to the optimum retiming phase. Thus the retiming pulse is kept at the optimum phase to enhance the signal quality.
