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 뒷면 하단부에 수문을 승하강 시킬수 있는 승강장치를 구성시켜 홍수시에 수문이 완전 개문되도록 하여줄수 있도록 구성시킨 구조이다. 
     수문의 인위적 작동이 필요하면 이동식 발전기 또는 전기의 힘을 이용하여 개폐 시킬수가 있을뿐만 아니라 최악의 조건하에서는 인위적인 조절에 의해서 개문시킬수가 있도록 된 수문인 것이다 
     고무댐이나 기계식수문의 경우 수문의 상단부로 유입수를 배출시켜주는 방식이다 보니 하천바닦은 항상 썩고 있기 때문에 녹조 현상이나 적조 현상에 의하여 광합성작용을 더욱더 활발히 하기 때문에 저장된 물이 더욱더 썩고 있는 것이 현실 것이다 
     본발명의 수문은 하단부로 유입수를 배출시켜주는 방식이다 보니 녹조 현상이나 적조 현상과 같은 광합성 작용이 발생하지 않기 때문에 수질이 오히려 개선되는 구조 의 수문인 것이다.

Abstract: PURPOSE: A device for resetting an IC circuit is provided to produce the stable reset signal regardless of the fluctuation of the voltage given to the IC chip or noises. CONSTITUTION: In a device of resetting an IC circuit, when the operational voltage(Vcc) is increased gradually from the ground voltage(GND), the base of a PNP transistor(12) maintains low level as with the grounding voltage(GND) until the base of the NPN transistor(11) reaches 2Volt. Thus, the R terminal of an SR latch(13) maintains low level. And as the S terminal maintains low level, the /Q terminal of the SR latch(13) produces high level. The reset signal(RST) of the collector of a second PNP transistor(14) becomes low level and is given to the IC chip. When the base of the NPN transistor(11) is above 2Volt, the reset signal(RST) is not affected similarly.
