Abstract: 본 발명의 촉매 조성물은 산화 지르콘 지지체 상에 한정된 양의 산화제이세륨을 분산시켜 산화제이세륨이 분산된 산화 지르콘 지지체와, 로듐 촉매 성분으로 이루어진다. 산화 지르콘 지지체의 산화제이세륨 함량은 산화제이세룸과 산화 지르콘을 합친 중량에 기초하여 약 15중량 를 초과하지 않는다. 생성된 촉매 조성물은 이것을 사용하였을 때 물 가스 이동 반응 및 탄화수소의 스팀 재형성을 촉진함으로써 삼원 전환 촉매계의 효율을 증대시킨다. 산화제이세륨을 분산시킨 산화 지르콘 지지체 상에 기재된 로듐을 촉매 유효량의 백금 촉매 성분과 함께 혼합하여 효율적인 삼원 전환 촉매를 얻을 수도 있다.

Abstract: The apparatus removes colloidal particles contained in a gaseous fluid, generated from the combustion boiler. The method is composed of touching the dust with steam or organic solvent vapour, cooling and liquefying in order to remove the colloidal particles. The apparatus comprises a dust removing chamber (8) provided in a passage (A) between a boiler pipe (1) and a rear pipe (10); a cooling chamber (9) over the chamber (8); a vaporizing duct (4) for a solvent (3), connected with the passage (A); a filtering tank (11) connected with the lower passage (A), the discharge pipe (5), the vaporizing duct, and a valve (12).

Abstract: 실리콘 웨이퍼 제조방법이 
     (a) 인상 실리콘 웨이퍼의 광투과특성(T OBS )를 평행편광을 브뤼스터각으로 인상 실리콘 웨이퍼에 입사해 측정하는 제1공정단계와, 
     (b) 기준 실리콘 웨이퍼로써 표리양면이 경면연마된 구멍이 있는 부유대역 실리콘 웨이퍼의 광투과특성을 평행편광을 브뤼스터각으로 부유대역 실리콘 웨이퍼에 입사해 측정하는 제2공정단계와, 
     (c) 제1공정단계동안 측정된 인상 실리콘 웨이퍼의 광투과특성(T OBS )과 제2공정단계동안 측정된 부유대역 실리콘 웨이퍼의 광투과특성(T O )을 기초로 격자간 산소농도 [Oic]를 산출하는 제3공정단계와, 
     (d) 제3공정단계동안 측정된 인상 실리콘 웨이퍼의 격자간 산소농도를 기준치와 비교하는 제4공정단계와, 
     (e) 인상 실리콘 웨이퍼를 제4골정단계에서 비교된 결과로써 만일 그것의 격자간 산소농도 [Oic]가 기준치로 부터 벗어난다면 불량이므로 제거하는 제5공정단계으로 구성된다.
