Abstract: 본 발명은 수문에 관한 것이다. 
     종래의 수문은 단순히 수압에 의하여 열리고 닫히는 수문이 있었으나 완전히 개문되는 수문은 없었던 것이 현실이다. 
     이러한 결점을 해소하기 위하여 본발명의 수문은 수문의 상부에 공기 저장통을 구성시켜 수문을 작동하고자 할 때에 공기 저장통의 공기를 인위적 또는 강제적으로 입출시키는 방식의 수문에 관한 발명인 것이다. 
     수문의 작동이 필요하면 이동식 발전기 또는 전기의 힘을 이용하여 개폐 시킬수가 있을 뿐만 아니라 최악의 조건하에서는 인위적인 조절에 의해서 개문시킬수가 있도록 된 수문인 것이다. 
     종래의 유압식 수문[실용신안등록제107651호]과 같은 유압 피스톤식 수문은 홍수시에 상류에서 흘러 내려오는 모래 자갈과 같은 물질에 의하여 수문을 지탱하여 주는 피스톤이 망가지기 때문에 수문의 수명을 단축시켯던 것이며 또한 홍수시에 수문 하단부에서 발생하는 버불 현상에 의하여 모래 자갈등이 수문의 하단부로 밀려 들어갈 수밖에 없는 구조로 인하여 수문이 열릴때에 수문하단부로 밀려 들어간 모래 자갈의 지랫대 현상에 의한 수문의 뒤틀림 작용으로 인하여 수문의 본래 기능을 상실하게 되는 것이다. 
     또한 고무판재로된 고무댐[보]의 경우[실용신안 등록제56240호]와 같이 물을 막고 있는 것이 고무로된 자료 이다보니 상류에서 흘러 내려오는 모래 자갈과 같은 것들이 고무판재에 충격을 가할 수밖에 없다보니 제품의 수명이 단축 될 수밖에 없었던 것이다. 
     그러나 본 발명의 수문은 이러한 결점들을 해결하고자 수문의 본체는 금속 또는 프라스틱 재료로 구성시켯으며 수문의 개폐는 공기 저장통의 팽창과 수축에 의하여 자동적으로 개폐 시키는 방식을 택한 것이다. 
     갑작스런 홍수에 의하여 수문의 작동이 필요할시에는 수위 감지센서에 의하여 작동하는 동력 장치에 의하여 공기 저장통의 공기를 배출하여 주면 자동으로 수문이 열리는 것이고 수문을 닫아놓을 필요가 있을시에는 동력 장치를 가동 시켜 공기저장통에 공기 또는 액체를 채워 주어 수문을 가동시켜주면 간단히 수문의 역할을 하여 주는 것이다. 
     또한 전기적 동력이 차단 되었을때에는 인위적으로도 수문을 개폐를 하여 줄수 있는 수동 개폐장치는 공지의 기술이기 때문에 상술하는 것을 생략 하기로 한다.

Abstract: 본 발명은 기판보지구 및 그 세정·건조장치와 세정·건조방법에 관한 것이다. 
     종래의 웨이퍼 반송 척(기판보지구)는 복수의 부재를 조립하여 형성되기 때문에, 웨이퍼가 대형이 되면 웨이퍼 척 및 그 세정·건조장치가 대형화되고, 세정·건조효율이 저하하는 문제점이 있었다. 
     본 발명은 기판보지구의 보지부재를 하나의 부재로 형성함으로써 보지부재의 강도를 저하시키지 않고 기판보지구 및 그 보지 홀을 소형화함과 동시에, 건조시간의 단축 및 스루풋 향상을 도모할 수 있는 기판보지구와, 세정용기의 상면에 한쌍의 개구부를 갖고, 2개의 보지부재를 동시에 세정·건조처리할 수 있는 세정·건조장치 및,  기판보지구와 세정용기를 상대적으로 이동가능하게 형성함으로써 기판보지구를 효율적으로 세정·건조처리할 수 있는 기판보지구의 세정·건조방법을 제시하고 있다.
