Abstract: 본 발명은 감광성수지판의 현상방법 및 장치에 관한 것이다. 감광성수지판은 종래의 인쇄판에 비해 조작성, 생산성, 가격 및 인쇄특성이 우수하여 근래에 급속히 보급되고 있으나, 감광성 수지를 현상하는 용출액의 사용에 있어서 세출시에 세출액중에 스컴이 발생되어 장치본체 및 인쇄판등에 부착되는 문제점이 있었다. 
     본 발명 방법은 감광성수지판을 세출액에 침지하여 미노광부를 비벼내어 현상할 때 세출액을 강제유동시킴으로써 미노광부의 응집석출을 방지하고, 한편으로는 현상공정중이나 후에 세출액중의 고형물을 제거한 후 얻어진 여액을 상기 현상용 세출액으로 재사용하는 것이다. 또한 본 발명의 장치는 세출조, 순환장치, 수지여과조를  포함하여 이루어지며 세출액조 외에는 필터가 부착되어 있다. 
     본 발명에 의해 감광성수지판의 미노광부의 응집석출이 억제되고 스컴발생이 저하되며 또한 여액을 다시 현상액으로 사용할 수 있다.

Abstract: 본 발명의 방법은 이미 유전물질이 커버링되어 있는 반도체 기판의 지역에 다결정 실리콘의 제1층(7)을 형성하고, 보호막으로 작용하는 제1절연층(8)및 다결정 실리콘의 제2의 얇은층(9)을 형성하고, 첫번째 유형의 전자소자, 예를 들어 다결정 실리콘의 두개의 레벨을 지니는 EPROM메모리 셀이 수용되는 소정의 지역을 제외한 영역에서 다결정 실리콘의 제2의 층(9)및 제1절연층(8)을 제거하고, 다결정 실리콘의 제1층(7)의 노출부를 도핑하고, 데포지션, 마스킹및 제거시킴으로써 제2유형의 전자소자, 예를들어 캐패시터가 수용되는 지역에서 다결정 실리콘의 제1층(7)에 제2의 절연층(10)을 형성하고, 다결정 실리콘의 제3의 층(11)을 형성하고, 두가지 유형의 전자소자가 위치하게 되는 지역위에 적어도 부분적으로 존재하는 상기 제3의 층의 소정의 영역을 마스킹하며, 그리고 상기 소정의 영역의 외부의 다결정 실리콘을 제거하는 동작의 시퀀스를 포함한다. 
     상기의 방법에 이어서 종래의 유형의 동작이 계속되고 따라서 두가지 유형의 소자의 물리적 특성및 디멘젼의 선택에 있어서 최대의 허용도및 정밀도를 감소시킴이 없이 예를들어 전극을 형성하기 위해 동일한 다결정 실리콘 디포지트 동작을 사용항 EPROM을 획득하는 것이 가능하게 된다.

Abstract: An operation control circuit for a  home  boiler  includes  a room switch, a low water level sensing section, a signal receiving sect. and a main control sect. The room switch comprises  a  ratch circuit for  selecting  a  function  among  four   functions,   a transforming switch, and a  comparing  circuit  connected  with  a thermister and a  termperature  setting  dial  to  its  anode  and cathode therminals respectively. The low water level sensing sect. includes a comparing circuit to compare the output of a sensor and the output of a static voltage circuit and to generate a signal to stop the operation. This controller gives a home boiler  automatic heating functions for the times of dwelling, sleeping and outing.
