The apparatus comprises: a Mn containing iron making furnace(10) with an oxygen lance(12) and a fine ore and coal combustion device(50); an ore supply device(20) for supplying large grain ore, general coal and additional material to the iron making furnace(10); a process gas circulation device(30) for separating iron, fine Mn system ore and coal dust from the process gas generated from the iron making furnace(10), and for discharging the process gas; a fine ore supply device(40) for supplying iron, fine Mn system ore, coal dust, prereduced fine ore and fine coal to the fine ore and coal combustion device(50).

Abstract: 하나의 프로세스와 상기 프로세스를 수행하기 위한 장치를 구비하는 시스템이 제1스플로 부터 제2스풀로 기록 테이프를 빨리 되감고 되감기 시간을 가능한 짧게 유지하며 테이프 및 루프 정보의 기계적 응력을 감소시키는 것으로 공개되어 있다. 이러한 목적으로, 최소 회전 속도가 결정되는데 이러한 속도로 부터 브레이킹 장치에 의해 기계적으로 너무 강한 응력을 받지 않고 제동될 수 있다. 이에 더하여, 최대로 설정된 감속 비는 상기 브레이킹 장치를 사용하지 않고 구동 수단(전기 모터)을 더 천천히 구동하므로 얻을 수 있다. 이러한 설정 감속 비는 루프 형태를 방지하며 비디오 테이프상의 필름 시작과 같은 마크를 인식하는 센서에 대해 테이프를 누르도록 선택된다. 되감기는 제1스풀은, 나머지 되감기 시간이 설정된 감속비로 테이프를 최소 회전 속도로 감소시키기에 충분할때까지 가속된다. 나머지 되감기 시간은, 최소 회전 속도 및 설정된 감속 비외에도, 제1 및 제2스풀의 반경과 같은 작동 매개 변수, 각각의 회전 속도 및 그와 같은 것을 포함하는 기간을 비교하므로 요구된 시간과 비교된다. 시스템은 비디오 테이프 카세트로 되감기 위해 사용될 수 있을 것이다.
