Abstract: 디지탈 위상-고정 루프는 위상 비교기와, 출력 신호가 위상 비교기에서 입력 신호와 비교되는 제어 가능한 발진기와, 상기 발진기 앞에 있는 루프 필터를 포함한다. 상기 필터는 위상 비교기의 최종 위상-측정값을 기억하기 위한 클럭 입력 레지스터와, 출력 신호가 레지스터 입력에 역으로 제공되는 클럭 레지스터를 포함하는 적분기를 포함한다. 위상 비교기의 입력 신호가 없거나, 교란 신호일때, 한 스위칭 신호가 발생되어 루프 필터내의 입력 레지스터를 즉시 삭제하고, 그 스위칭 신호의 출현 이후에, 루프 필터의 적분기 내의 레지스터는 한정된 수의 클럭 사이클 내에서 제로(0)로 리세트된다.

Abstract: The producing method of a trimanganese tetroxide (Mn3O4) for a magnetic material is characterized by (a) dispersing an electrolytic metal manganese powder into the water to obtain a suspension, (b) heating the suspension at 80-120 deg.C. (c) adding a liquid ammonia to it, and regulating a reacted solution to be pH 8-10.5, and (d) reacting the reacted solution with an oxidizing agent i.e. oxygen, oxygen-contg. gas or hydrogen peroxide, and recovering the produced trimanganese tetroxide.
