Title: Device for projecting tv pictures
Inventor: MIYATAKE YOSHITO
IPC: H04N5/74
Filed: 1985-05-10
Abstract: PURPOSE:To produce a good TV picture by holding a liquid transparent substance in a device for projecting TV pictures in such a manner that the liquid does not leak outside the device during its assembly and by deforming the transparent substance according to its volume variation in order to prevent the substance from being separated from a face plate or a lens element. CONSTITUTION:A little squashed frame 23 made of elastic material which is placed between a face plate 19 and a lens element 20 becomes in close contact with the face plate 19 and the element 20 due to restoring force produced by the elasticity of the frame 23. Therefore, during assembly, the nonhardened liquid filled in the space surrounded by the face plate 19, the lens element 20 and the frame 23 does not leak outside and is hardened into Si gel while being in close contact with the element 20. During use, as the hardened Si gel is held by the plate 19 and the element 20 which are located at a given distance restricted by a spacer 21, the thickness of the Si gel is constant regardless of temperature and the Si gel expands or contracts only in radial direction. The elastic frame 23 is squashed when the temperature of the gel increases to above room temperature and the surface of the gel expands when the temperature becomes lower than room temperature. As a result, the frame 23 is deformed by expansion or contraction of the gel in its radial direction, thereby preventing any excessive internal stress from being generated in the gel.
