Title: 궤도차량의 진동을 방지할 수 있는 레일의 연결부위 구성방법과 기존 레일의 효과적인 교체방법
Filed: 1998-11-06
Abstract: 본 발명은 궤도차량의 진행 선로인 레일을 구성함에 있어, 레일은 온도변화에 따라 팽창과 수축을 반복하며, 때문에 선로를 구성할 때 하나로 이어진 레일로 구성하지 아니하고 적절한 길이를 갖는 레일을 연결하며, 그 연결부위에는 위 열팽창 등으로 인한 변형이나 이탈을 방지하기 위하여 레일의 열팽창등을 수용할 수 있는 충분한 공간을 두고 각 레일을 침목에 고정하여 하나의 정해진 선로를 구성한다. 
     그런데 기존 레일의 상기한 연결부위는 서로 연결하는 각 레일의 끝단 단면을 수직, 수평으로 상기한 열팽창 등을 수용할 공간을 두고 서로 연결하고 있다.    때문에 궤도차량의 차륜이 서로 단절된 레일간 상기 연결부위를 지날 때 차륜의 외곽 원주면은 상기 연결부위의 레일의 상단 단면과 면 접촉이 끊겨졌다가 다음 연결된 레일에 면 접촉하는 순간 사이에 궤도차량의 하중이 낙하하였다가 다음 연결된 레일의 상단 면과 충돌하게 되고 그때 차량의 하중과 속도에 따른 덜컹하는 진동음을 유발하고 고속에서 연속음을 발생하여 소음공해를 유발하고 있다. 
     그럼에도 누구하나 이를 적극적으로 해소할수 있는 방안을 창출하려 들지 아니하고 소음공해를 감수하여 왔다. 
     여기에서 우리는 상기 연결부위의 단면을 구성상 기술적으로 서로 적절한 형상의 요철을 이루워 교차하도록 구성함으로서 궤도차량의 차륜이 상기 서로 교차하는 연결부위를 지날 때 서로 단절되어 연결된 두 개의 레일 중 어느 하나의 상단면과는 면접촉을 하게되어 레일간 연결부위에 서로 단절된 공간이 존재함에도 궤도차량의 하중으로 인한 진동과 소음을 방지할 수 있는 레일과 레일간 연결방법을 안출하고. 
     또한, 기존 설치되어 사용중인 레일에 있어서, 전체를 대체하지 아니하고 극히 제한적인 일부분만을 절단하고 그 절단된 조각을 그대로 사용하여 레일과 레일간을 연결하여 서로 교차하는 레일의 연결부위를 구성하거나, 
     또한, 기존 설치되어 사용중인 레일을 대체함에 있어서 연결부위의 한쪽 레일의 최소한 부위를 절단하여 떼어내고 그 공간에 최소한의 구성을 갖는 레일조각을 서로 교차하도록 각 레일의 끝단 단면에 접합하여 연결부위를 구성함으로서 기존 레일을 효과적으로 진동 소음이 없는 레일로 대체할수 있는 방법을 제공 하는 것이다.

Abstract: α-올레핀이 탄소수 5 이상(고급 알파-올레핀(HAO))을 갖고, 공중합체가 메탈로센 촉매 시스템을 사용하여 제조한, 프로필렌, α-올레핀 공중합체로 제조한 성형 또는 압출 제품은 프로필렌 공중합체가 탄소수 4 이하의 α-올레핀을 함유할 때 보다 실질적으로 더 높은 저온 유동 저항성 및 레질리언스를 제공한다.  극한 인장 강도 및 충격 강도와 같은 기타 특성도 또한 실질적으로 더 높다.  상기 중합체는 단독사용하거나 또는 열가소성 올레핀(TPO)와 함께 압출 프로파일 및 성형 부품으로 유리하게 사용할 수 있다.  프로필렌 HAO 공중합체로 제조한 부품 또는 이들로 제조한 화합물은 프로필렌 에틸렌 공중합체보다 개선된 크립 저항성을 나타낸다.
