| Number | Title | Issue Date |
| 5363149 | Projection television set A projection television set includes a body composed of at least two divided upper and lower units, a screen assembly having an integrally formed screen corresponding to the body, and a plurality of bolt and nut assemblies for coupling the divided units t... | 11/08/1994 |
| 5089896 | Color deviation prevention device in projection display with minimized white chromaticity deviation A projection display of the type which projects the respective images emitted from a plurality of tubes on a rectangular screen through lenses arranged correspondingly to the projection tubes, thereby to compose the images by overlapping, wherein the lens... | 02/18/1992 |
| 4651217 | Video projector A video projector has a structure wherein a projection lens is disposed to be fixed at a predetermined distance with respect to a front surface of a faceplate of a projection cathode-ray tube through a medium. The medium has substantially the same refract... | 03/17/1987 |
| 4423438 | Projection type cathode ray tube with masking means A projection cathode ray tube is provided with elements for correcting a spherical aberration in the optical system. These elements include a correction lens disposed in front of the tube and a masking member adjustably mounted on the lens. The masking me... | 12/27/1983 |
| 4305099 | Light collection system A light collection system for projectors, such as light valve projectors, has a compound reflector associated with an arc lamp. The compound reflector includes an ellipsoidal reflector positioned to collect a portion of the light from the arc lamp and ref... | 12/08/1981 |
| 4293196 | Objective lens system with aspheric Fresnel elements A high speed projection lens system particularly adaptable for a television projection system having a viewing screen and a video image forming surface is provided. The projection lens system includes a first thin meniscus lens element convex to the proje... | 10/06/1981 |
| 4234894 | Reflecting optical system for projection television A projection television system having a light emitting target and a screen for realizing a projected video image is provided with an improved reflecting optical system which provides enhanced resolution and uniform correction of aberrations across a proje... | 11/18/1980 |
| 4197559 | Color television display system Means for projecting a color television picture by rotating or otherwise moving a multi-colored filter in front of a monochrome projection tube and detecting the color of the projected light to electronically switch the appropriate color video input to th... | 04/08/1980 |
| 4177400 | Projection cathode ray tube having target angularly and longitudinally adjustable to tube axis A projection cathode ray tube has a target that is mechanically adjustable by means external to the evacuated envelope.
