Abstract: 본 발명은 보일러내의 튜브를 연결지지하는 주조지지구에 관한 것으로, 상하부링(26,22)상에 성형되면서 페라이트튜브에 용접되지 않고 결합되는 암수지지돌기(14,12; 28,24)를 갖추고 있고, 한쪽 튜브에 설치된 상기 수지지돌기(12,14)는 인접튜브에 장착된 암지지돌기(14,28)과 결합되게 되어 있으며, 상기 암수지지돌기(14,12; 28,24)와 링(26,22)은 내부식성과 내열성을 갖는 오오스테나이트재질로 성형됨과 더블어 오오스테나이트재질과 페라이트튜브사이에 용접접합이 어렵기 때문에 이들과 상이한 용접금속으로 용접시켜줄때에 야기되는 문제점이 해소되게 되며, 상기 암수지지돌기(14,12; 28,24)는 하나 혹은 다수개의 페라이트용접지지부(30,32)에 의해 튜브상에서 축방향으로 지지되게 되어 있고, 상기 페라이트용접지지부(30,32)는 암수지지돌기(14,12; 28,24)의 한쪽 혹은 양쪽 축방향 선단부와 인접된 튜브상에 배치되어 있다.

Abstract: The medium enhances the traveling stability and the durability of the magnetic tape. The materials below are used for backcoating layer: the first material, Di-Butyl Phthalate (DBP) solutions of 100-200cc/100g and carbon black of 20-30 nm particle size; the second material, DBP solutions of 80cc/100g and carbon black of 60-100 nm particle size. The first and second material in weight ratio of 1:9 - 5:5, and 50-200 weight ratio of carbon to reference binder 100 weights are used for backcoating layer whose thickness is 0.5-1.5 μm.

Abstract: 본 발명은 고상과 액상으로 이루어진 합성용융염 전해질을 이용한 고온용 성분센서에 관한 것이다. 
     본 발명에서는 금속용융액을 측정전극으로 하며, 특정 금속의 순금속 또는 그 특정 금속을 포함하는 합금을 표준전극으로 함과 동시에, 상기 표준전극에 접촉되는 전극활성물질은 이온 전도성을 나타내는 알칼리 금속 할로겐화물 또는 알칼리 토류 금속 할로겐화물중 적어도 한 종류인 할로겐화물과 상기 특정 금속 할로겐화물을 포함하며, 상기 할로겐화물의 어느 한 할로겐화물이 고성과 액상으로 이루어진 전극활성 물질로, 상기 금속용융액에 접촉 가능하게 구비되며, 전해질로서도 이용될 수 있는 용융금속용 성분센서와 이를 구비한 금속용융액 성분조절장치를 제공한다. 본 발명의 용융금속용 성분센서는, 용융금속중의 특정 성분 농도를 연속적으로 전기적인 신호로 검지할 수 있으며, 온도 420~800℃의 비교적 고온에서 사용할 수 있고, 게다가 넓은 농도범위에서 고분해능력을 가지고 있다.
