IPC: G02F1/1335
Filed: 1998-06-30
Abstract: PROBLEM TO BE SOLVED: To provide a process for producing a color liquid crystal display element with printing on inside surfaces which is capable of making film thicknesses uniform in spite of a dispersion in the printing width of color filter films and is capable of obtain sufficient color densities as the color filter films. SOLUTION: The color filter films to be formed are divided to the films above a boundary width and the films below the boundary width according to their printing widths in this process.

Title: Microwave electron tube
Inventor: SUGIYAMA TSUTOMU
IPC: H01J23/20
Filed: 1990-07-12
Abstract: PURPOSE:To suppress the elevation of the temperature of a resonant so as to obtain stable characteristic by using a silicon carbide ceramic (SiC), by which high frequency energy is absorbed, as a part of the wall of the resonant cavity. CONSTITUTION:A plate-shaped cavity wall 20 that forms a resonant cavity is made of copper, while a cylindrical cavity wall 21 is made of SiC which is a high frequency loss material. A conductor layer 23 is formed on a part of the inner surface of the cavity wall 21 made of SiC, and a part of the resonant cavity wall is thus formed along with SiC. The damping amount of copper and SiC is set to certain levels in such a way that the surface area ratios thereof are differed according to the required amount of microwave loss in each cavity. Since the SiC of the cavity wall is directly exposed to the outside of a vacuum atmosphere, heating efficiency is increased. The raise of the temperature is reduced thereby, and stable operational characteristic can be obtained.
