Abstract: 본발명은 시야각을 넓게 형성할 수 있는 액정표시소자 제조방법에 관한것으로, 종래에는 액정표시소자의 시야각방향에서 좌우로 불균일한 콘트라스트가 발생하였으나, 본발명에서는 상,하부배향막(12,11)의 러빙방향 대칭축을 수평축으로 하지 않고 수평축에서 10˚~30˚이동하므로써 액정표시소자의 시야각이 좌우로 균일하며 넓어지므로 상기 결점을 개선시킬수 있는것이다.

Abstract: 정보 시스템은 기록 캐리어(1) 및 재생 장치를 포함한다. 정보는 제 1 물리적 파라미터의 변동들의 형태로 기록 캐리어(1)상에 기록된다. 재생 장치는 상기 제 1 물리적 파라미터의 상기 변동들에 응답하는 변환기(41)에 의해 기록 캐리어를 주사한다. 정보 회복 회로(42)는 변환기(41)로부터 수신된 검출 신호로부터 정보를 회복시킨다. 기록 캐리어(1)는 상기 제 1 물리적 파라미터와는 상이하지만 상기 변환기(41)에 의해 검출 가능한 유형인 제 2 물리적 파라미터의 제 2 변동을 나타낸다. 검출 회로(43)는 변환기(41)로부터 수신된 검출 신호에 기초하여 제 2 변동의 존재를 검출한다. 검출 수단에 응답하여 회로(44)는 상기 제 2 변동들의 존재가 검출되는 경우에 정보 회복 회로(42)의 동작을 가능하게 한다. 일반적인 유형의 복사 기계들은 단지 제 2 물리적 파라미터의 변동들을 복사하지 않고서 정보를 표현하는 물리적 파라미터들의 변동만을 복사한다. 이러한 복사 기계에 의해 얻어진 복사에 관한 정보는 회복될 수 없다. 그러므로 기록 캐리어들의 복사는 보다 덜 용이하게 된다.

Abstract: PCT No. PCT/GB90/01895 Sec. 371 Date Jun. 4, 1992 Sec. 102(e) Date Jun. 4, 1992 PCT Filed Dec. 5, 1990 PCT Pub. No. WO91/08037 PCT Pub. Date Jun. 13, 1991.A method of producing a particulate-solid-bearing air-permeable sheet of material of other than woven and knitted material selected from non-woven fabrics and open cell foam materials includes the following steps: entraining a particulate solid in a gaseous carrier in the substantial absence of fibrous material; disposing one face of a preformed air-permeable sheet material, which material has a density at or below 0.25 g/cm3, in the path of a stream of the gaseous carrier and entrained particulate solid, whilst maintaining a pressure drop across the thickness of the preformed air-permeable sheet material from the one face to the other face of the air-permeable sheet material, whereby to entrap some or all of the entrained particulate solid on or on and in the air-permeable material; and fixing the retained particulate solid on or on and in the air-permeable material with a binder. The mean pore size of the preformed sheet material is greater than the mean particle size of the particulate solid.
