Title: Process for coating glass
Inventor: GRUNDY BARRY THOMAS
IPC: C03C17/00
Filed: 1989-10-14
Granted: 1996-07-25
Abstract: A process for coating a moving ribbon of hot glass by chemical vapour deposition comprises establishing a first flow of a first reactant gas along the hot glass surface substantially parallel to the direction of movement of the glass, establishing a second flow of a second reactant gas as a turbulent flow at an angle to the glass surface, introducing said second flow into said first flow at said angle, while avoiding upstream flow of said second reactant gas in said first flow, directing the combined gas flow along the surface of the hot glass as a turbulent flow, and thereafter withdrawing the used coating gas away from the hot glass. The process enables a substantially uniform coating over 200 nm thick to be deposited in a short coating zone, and is useful for applying metal oxide coatings, for example fluorine doped tin oxide coatings, to hot glass.

Abstract: 본 발명은 액정표시 소자의 투명 도전성기판 사이에 위치되는 고분자 액정복합물을 제조함에 있어서, 분체상의 열가소성 고분자 수지를 가압하고 연화점에서 가열후 냉각시켜 다공성 흡수성 수지층으로 만들고, 여기에 액정을 주입하여 다공성 고분자 액정 복합막을 제조하는 방법으로, 투명 전극사이에 고분자에 분산된 액정들이 구적으로 혹은 고분자 그물망 사이에 분포하여 있는 형태를 띄고 구적이나 그물망 사이에 있는 액정들이 전계 인가시 전계방향으로 배열함에 의하여 광이 투과하게 되고, 전계를 인가하지 않을때는 구적별로 액정분자 배열이 무질서하게되어 고분자와 굴절율의 불일치에 의하여 빛이 산란되는 원리를 이용하여 편광판을 사용치 않고도 광의 투과 및 차단을 할수있어서 광 이용효율이 크게 개선되며, 종래 고분자 액정 복합막이 액정의 완전한 상분리가 되지 않는 관계로 구동시 고분자 그물구조가 파괴되어, 장시간 사용시 노화가 크게 진행되는데 비하여, 본 발명의 고분자 액정 복합막은 액정과 고분자가 전혀 상용성이 없고 고분자 매트릭스가 매우 견고하여 장시간 사용해도 특성이 변하지 않는 특징을 가진다.

Granted: 1997-07-05
Abstract: A manufacturing method of a sample for analyzing phenol of an infinitesimal quantity capable of exactly and simply analyzing a phenol component of an infinitesimal quantity which is present at water. In the method, a sample less than 1ppm to be analyzed and a methylene chloride are put in a powder liquid beaker(1) to extract a phenol component. The powder liquid beaker(1) is heated and fixed and a methylene chloride layer is isolated and put in an enriching device(4). The isolated methylene chloride layer is enriched by a helium gas at 0-4 degree.C.
