Title: Zeolite complex inorganic film containing palladium having high transmission selectivity for hydrogen gas
Inventor: PARK SANG EON
IPC: B01J20/16
Filed: 1998-10-14
Abstract: PURPOSE: A new complex inorganic film is provided to disperse palladium particles highly on the surface after coating a zeolite molecule having fine holes about 5-10 angstroms on a ceramic film. CONSTITUTION: A zeolite complex inorganic film containing palladium is composed of a porous tube, a zeolite molecular layer and a palladium layer. The porous tube is applied to a material having conditions such as 6-25mm of an outer diameter, 1-3mm of thickness and 4nm-12 micrometers of pore size. The zeolite molecular layer is produced by treating with heat after coating a mixture of a silicon precursor with a surfactant of a fourth graded alkyl ammonium salt having 12-20 chains of carbon on the surface of the porous tube. The thickness of a zeolite molecular layer is about 1-30 micrometers and the pore size is in a range of 5-10 angstroms. The pore size is controlled by primarily treating heat for 1-48 hours at a temperature of 100-120°C after coating the zeolite molecule and secondarily heat treating for 12-100 hours after raising temperature up to 150-180°C.

Abstract: PURPOSE: Modular seal assembly for sealing a circular opening through wall, usually with one or more conduits extending through seal. CONSTITUTION: Assembly includes an outer pressure annulus and a thick inner pressure disc, both of natural or synthetic rubber, EPDM, urethane, or other elastomer. In the outer annulus elastomer is an annular series of interconnected blocks of length (L1) having a central opening of radius (R2), a series of pressure bolts compress blocks axially, expanding the annulus both outwardly and inwardly. Inner disc, which has an outer radius of about(R2) and is interlocked with elastomer blocks of the outer annulus, has a multiplicity of circular layers, much like onion; the layers are concentric about opening through which a conduit usually extends. Tightening the pressure bolts causes the outer annulus to compress disc, forcing disc against conduit to complete a seal; elastomer blocks of the outer annulus seal against the wall opening.

Abstract: 본 발명은 비간섭성(incoherent) 전송방법을 사용하는 디지털 전송 시스템용 수신기에 관한 것으로 이 수신기는 전송 채널에 의해 전송된 심볼 a[k] 시퀀스에 대한 추정을 수신된 심볼 r[k]로부터, 전송특성을 기술하는 임펄스 응답 h[k]에 의해 형성하는 등화기를 포함한다.  비간섭성 전송방법 및 심볼간 간섭을 갖는 전송 채널들에서 수신품질을 개선하기 위해서, 전송된 심볼 a[k] 시퀀스에 대한 추정 를 결정하기 위해 등화기가 비간섭성 최대 개연성(likelihood) 시퀀스 추정(MLSE) 방법을 수행하는 것을 제안한다.  심볼간 간섭을 갖는 채널에서, 비간섭성 MLSE 방법은 공지된 비간섭성 수신방법보다 명백하게 양호한 결과를 제공한다.  주파수 및 위상 오프셋에 대해, 비간섭성 방법은 모든 공지된 간섭성 수신방법보다 상당히 더 강하다.  이러한 방식에서 고가의 주파수 및 위상제어를 생략할 수 있다.
