Abstract: 전력 분배용 전자 제어식 재폐기는 전선 전류에 응답하여 출력하도록 결합된 최소한 하나의 전류 변압기에 의해 전력을 공급받는다. 전압은 전선 전류에 응답하여 대용량 캐패시터와 소용량 캐패시터에 저장되며, 전선 전류의 레벨을 결정하기 위하여 기준 전압과 비교된다. 전선에 비정상적으로 높은 레벨의 전류가 나타나면 전선은 짧은 시간의 기간 동안 개방된다. 캐패시터에 저장된 에너지는 낮은 전선 전류 상태 동안 재폐기에 전력을 공급하도록 제공된다. 상기 전선 개방 후의 소정의 시간 기간의 만료시에, 재폐기는 전선을 재폐한다. 비정상 상태가 지속되면 재폐기는 또다시 전선을 개폐한다. 전선 전류의 써지가 일어나면 대용량 캐패시터는 회로로부터 효과적으로 제거되므로, 대용량 캐패시터가 충전되는 동안 응답이 지연되지는 않는다. 따라서 소용량 캐패시터의 충전은 즉각적인 응답을 위해 급속 시동을 제공한다. 회로는 동작 모드를 선택하기 위해 마이크로프로세서에 의해 사용될 수도 있는 주파수로 전선 전류 레벨을 변환시키는 새로운 회로를 포함한다.

Abstract: The method for bonding a polyethylene foamed material (2) as a heat insulating material on the zinc-plated color steel plate(1) is characterized by (a) coating a mixed film (3) of a low density polyethylene resin and a polyamide resin on the surface of the foamed material, and (b) heating the color steel plate by the radiation heat of 30-40 deg.C. and then melt-fusing the mixed film by the infrared heater of 250-300 deg.C. The manufactured article has a good heat stability and antioxidation property, and is used as a roof material of the factory building.

Abstract: 극성 아미드 용매 중에 1.0 ∼ 2.5 d1/g의 고유 점도를 갖는 4 ∼ 10 중량 % 의 파라 - 아라미드 및 2 ∼ 10 중량 % 의 알칼리 금속 할라이드 또는 알칼리 토금속 할라이드를 함유하면서 광학적 비등방성을 나타내는 저중합도의 파라 - 아라미드; 상기 1 번의 저중합도의 파라 - 아라미드 도프를 방사함으로써 얻어지는 파라 - 아라미드 섬유 ; 상기 2 번의 파라 - 아라미드 섬유를 짧은 섬유로 만들고, 기계적인 고전 단력으로서 짧은 섬유를 미소섬유화하고, 형성된 미소섬유를 건조하여 얻어지는 파라 - 아라미드 펄프; 2 ∼ 10 중량 % 의 알칼리 금속 클로라이드 또는 알칼리 토금속 클로라이드가 용해된 극성 아미드 용매 중의 파라 - 배향 방향족 디아민 1 몰에 0.94 ∼ 0.99 몰의 파라 - 배향 방향족 디카르복실산 할라이드를 가하고, -20 ∼ 50℃ 의 온도에서 중합 반응을 수행하여 파라 - 아라미드 농도가 4 ∼ 10 중량 % 인 저중합도의 광학적 비등방성 파라 - 아라미드 도프를 형성하며, 이 도프를 방사하는 것을 특징으로 하는 파라 - 아라미드 섬유의 제조방법 ; 
     1.00 몰의 파라 - 배향 방향족 디아민에 0.95 ∼ 0.98 몰의 파라 - 배향방향족 디카르복실산 할라이드를 가하는 것을 특징으로 하는 상기 4 번의 파라 - 아라미드 섬유의 제조방법 ; 및 상기 제 4 번 또는 5 번의 파라 - 아라미드 섬유를 절단하여, 짧은 섬유로 만들고 기계적인 고전단력으로서 미소섬유화하여 얻어진 미소섬유를 건조 시키는 것을 특징으로 하는 파라 - 아라미드 펄프의 제조방법 등이 개시된다.
