Abstract: The apparatus includes a display section (1)  for  displaying the check result of the illumination of an optical source  (4).  A processor (2) supplies reference level signals to an optical level detector (7) to display any abnormality in the illumination of the optical source  (4).  The  optical  level  detector  (7)  receives optical levels through a  charge  coupled  device  (6)  after  the optical beams are reflected from a text paper (5), and  then,  the optical level detector (7) compares  the  optical  levels  with  a reference  level  to   discriminate   any   abnormality   in   the illumination of the optical source (4).  With  the  apparatus,  an abnormality in the illumination  of  the  optical  source  can  be easily detected.

Abstract: A belt (16) for use on an extended nip press for dewatering a fibrous web (17) is shown. The belt (16) includes a base fabric (22) having machine-direction (24) and cross-machine direction (26) yarns and takes the form of an endless loop. Either the machine-direction (24), or the cross-machine direction (26), yarns are spun yarns of staple fibers (34). The base fabric (22) is completely coated and impregnated with a polymeric resin, such as polyurethane, to render it impervious to liquids, especially lubricating oil. The inner surface (20) of the resulting belt slides over the arcuate pressure shoe component (14) of the extended nip press during its operation. The outer surface (19) of the belt is provided with grooves (30) separated by land areas (32) which together define channels for water pressed from the fibrous web (17) in the press nip. The land areas are anchored to the belt by means of staple fibers (34) from the spun yarns embedded in the coating (28) and thus resist delamination.

Abstract: 반응기 및 펌핑수단을 통한 배관에 의해 반응기에 연결된 외부의 열교환기를 포함하는 염화 비닐 단량체의 현탁 중합용 중합 반응기 시스템에 있어서, 반응기의 능력을 크게 상승시킬 경우 반응기의 재킷  및 / 또는 리플럭스 콘덴서의 냉각능력의 부족분을 보완하는데 개선점이 있다.  종래의 펌프를 사용하는 외부의 순환경로는 그 경로의 내벽에 둘러붙는 중합체 스케일 침착물과 수지제품의 품질저하라는 심각한 문제점을 갖지만, 이러한 단점은 열교환기를 통한 중합 혼합물의 순환을 위해 원추상의 허브 둘레에 단일 나선 스크루 블레이드 형태의 임펠러를 갖는 특수펌프를 사용하여 해소될 수 있다.

Abstract: 본 발명은 제어기의 조작 패널에서의 키이입력 확인 시스템에 관한 것으로, 특히 제어기의 조작 패널상에 설치된 기능 설정 버튼들로 부터 입력된 제어명령 신호를 메인 콘트롤러가 데이터 버스로 읽어들여 판단함과 동시에 그 확인신호를 디코더를 통해 표시출력단으로 표시되게 함으로서 제어기 시스템의 메인 콘트롤러에 제어명령신호가 정확히 전달되는지의 여부를 명백히 확인할 수 있어 그에 다라 제어기를 통한 제어시스템의 동작을 정밀 제어할 수 있도록 된 제어기의 조작 패널에서의 키이입력 확인시스템에 관한 것으로서, 각종 제어기능이 선택됨에 따라 그에 해당하는 제어신호를 송출하도록 된 키이입력부(1), 이 키이입력부(1)로 부터 입력된 각종 제어신호를 판단하여 그 판단된 제어신호에 따라 제어시스템을 동작시킴과 함께 그 제어신호의 입력확인신호를 송출하도록 된 메인 콘트롤러(3), 그리고 이 메인 콘트롤러(3)의 입력확인신호를 입력신호로 하여 각종 제어신호에 해당되는 표시신호를 발생하도록 된 디스플레이부(4)로 구성되어, 상기 키이입력부(1)의 제어명령신호가 메인콘트롤러(3)에 전달되게되면 이 전달된 제어명령신호를 메인콘트롤러(3)에서 판단한 후, 그 판단된 제어신호를 제어시스템으로 전송함과 동시에 제어명령신호의 입력여부를 확인하는 신호를 디스플레이부(4)로 출력하여 제어신호의 입력을 표시하도록 되는 것을 특징으로 하는 것이다.

Abstract: 본 발명은 테이프 레코더의 폴베이스 가이드장치에 관한 것이다. 본 발명은, 한쌍의 폴베이스가 드럼의 입사측과 출사측 각각에 설치되고, 그 폴베이스들을 가이드장공에 이동 가능하게 설치하여 되는 테이프 레코더의 폴베이스 가이드장치에 있어서, 상기 가이드장공이 한쌍의 폴베이스를 공유하는 공유부분과 이로부터 두갈래로 분기되는 가지부분으로 형성되고, 상기 가이드장공의 분기된 부분에서 한쌍의 폴베이스를 각각의 가지부로 분리 이동시키기 위한 분리수단이 구비되어 된 점에 그 특징이 있다. 따라서 데크를 소형화 시킬 수 있게 되어 테이프 레코더의 소형화가 가능하게 되고, 종래에 비하여 큰 직경의 드럼을 사용할 수 있게 되어 테이프의 떨림을 극소화 시킬 수 있게 된다.

Abstract: 본 발명은 드로워형 씨디피의 드레인 열림/닫힘 제어방법에 관한 것으로, 종래에는 각 동작을 수행하기 위해 키입력이 들어오면 단순하게 각 명령에 해당하는 출력을 계단형태로 하여 트레이구동모터에 인가하기 때문에 정지상태에 있던 트레이가 갑자기 움직이기 시작한다. 
     이때 트레이에는 정지마찰력에 의한 진동이 발생하여, 이 진동이 픽업에 전달되어 콤팩트디스크의 트랙을 이탈하는 트랙점프가 일어난다. 
     이에따라 음이 끊기는 현상이 생겨 사용자가 정확한 음을 들을 수 없는 문제점이 있었다. 
     본 발명은 이러한 문제점을 해결하기 위하여 트레이를 열고 닫을시 처음 일정기간동안은 펄스신호에 의해 트레이를 구동시켜 서서히 감속운전하다가 일정시간 이후에 트레이를 정상적으로 구동시킴으로써 트레이 구동시작시 진동을 최소화하도록 하는 것으로 연주중인 트레이를 열거나 닫을 수 있도록 되어 있는 드로워 형태의 씨디피에 적용할 수 있다.
