Abstract: A catch (24) is released from a groove in the outer casing (10) so as to deploy the projection screen (13) in its holder (17c) after rotation of its cover (30) about a hinge (20). The support (23) of a mirror-holder (18) is seated into another groove (22). Light from a lamp is reflected from the LCD mirror (16) to the projection lens (11) and after reflection from a fixed mirror (14) is redirected by the movable mirror (15) to the screen. For forward projection a separate screen is placed in front of the holder (17c). The portable projector has large screen suitable for either forward or back projection.

Title: Multivision scope
Inventor: SHIN SOK-KYUN
IPC: G02B27/22
Filed: 1992-01-25
Granted: 1994-09-24
Abstract: The multivision scope consists of left and right polyhedral lenses for both eyes to for a stereoscopic peep view and the swivel prevention part forming reference line within the magnification part of the taper type body with perspective window. The magic glass is formed by the above polyhedral lenses. The both supporting parts which forms the grips with both side walls of magic glasses, uneven faced guides and projecting parts for blocking are capped with a supporting cap to move both magic glases horizontally.

Abstract: 본 발명은 웰 확산층과, 로코스법에 의한 분리영역과 SiO 2 층, SiN층, 산화 SiN층으로 된 3층 게이트 절연층을 형성하는 공정을 가진 고체 촬상장치에 관한 것으로 산화 공정, 실리콘 표면 노출공정, 세정 공정등을 가능한 줄이고 화상 흠결의 발생율을 저하시켜 고해상도를 얻을 수 있게한 것인바, 이는 반도체 기판위에 SiO 2 층을 형성하고 이 SiO 2 층을 형성하며 불순물을 주입하여 웰 확산층을 형성하고 소자 분리 영역의 질화막을 제거하여 채널 스톱용 불순물을 주입하며 산화성 분위기 가운데에서 열처리하여 웰 확산과 소자분리영역의 선택적 산화 및 질화막 표면의 산화를 동시에 실시하여 이루어진다.
