Abstract: 본 발명은 FM 변조회로 (예컨대 음성신호를 FM 변조하는 것) 에 있어서의 중심 주파수의 안정화에 관한 것이다. 
     PLL회로로 구성된 FM 변조회로에 있어서, 전류원 동작의 루프필터에 있어서의 콘덴서를 전원전압에 관련되는 전압으로 바이어스하는 것을 특징으로 하는 중심 주파수 안정화회로는 전원 상승시에 발생되는 제어신호에 의거하여 상기 루프필터의 시정수를 실질적으로 저하시키는 특징을 갖는다. 
     즉 제1 구성에서는 전원의 상승과 동시에 콘덴서가 소정전압으로 바이어스되므로 PLL의 중심 주파수에의 인입을 빨리할 수 있다. 
     그리고, 전원 투입시에는 소정기간 출력되는 제어신호에 의해 루프 필터의 시정수가 작게 되므로 응답을 빨리할 수 있다. 
     본 발명에 따르면, FM 변조회로에 대하여 무조정화를 위하여 PLL회로를 이용할 경우에도 전원 상승시 등에 있어서 신속하게 중심 주파수를 안정화할 수 있는 효과가 있다.

The circulating extraction agent 2 with 3.0-3.5% conc. of chlorine ion is formed by mixing the middle-stage extraction soln. 1 with IMP of 2.0-2.5% obtained after the first extraction and the middle-stage extraction soln. 3 with IMP of 2.0-2.5%. The last-stage extraction soln. 1 with IMP of 0.2-0.4% is used for the first- and middle-stage extractions, and then 2.0% HCL is used for the last-stage extraction.
