Abstract: With respect to a vacuum tube having a reduced pressure vessel containing an electric discharge gas sealed therein, problems such as the lowering of discharge efficiency owing to an organic material, moisture or oxygen remaining in the reduced pressure vessel have taken place conventionally. It has been now found that the selection of the number of water molecules, the number of molecules of an organic gas and the number of oxygen molecules remaining in the reduced pressure vessel, in a relation with the number of molecules of a gas contributing the electric discharge allows the reduction of the adverse effect by the above-mentioned remaining gas. Specifically, the selection of the number of molecules of the above electric discharge gas being about ten times that of the above-mentioned remaining gas or more can reduce the adverse effect by the above-mentioned remaining gas.

Abstract: A device (10) for introducing hydrogen into a flat display (14) of the field emission or plasma addressed liquid crystal type is described, formed of a reservoir (11) containing a hydrogen accumulator material (21) connected to the internal space (13) of the display by means of a wall (15) permeable to the passage of hydrogen gas as a function of the temperature. The device comprises a heater (19) and a heater (22) for bringing respectively the wall and the accumulator material to the desired temperatures, or a single heater which carries out both cited functions. There is also described a method by which the device is activated whenever the flat display is working, the switching on of said heater being arranged in order to bring the wall itself to a previously calculated temperature.

Abstract: The Emission controlled field cold Cathode system has an empty reservoir placed in the vacuum environment of a Field Effect emitter. The emissions are transmitted from cone shaped sections. The partial pressure of the gas in the vacuum reservoir is made equal or less than C/I, where C is a constant and I is a maximum value of emission current. A control system is used to control the partial pressure.

Abstract: LD-7490 An improved pressed glass lens member for a sealed beam lamp unit is provided to include an outer sealing rim of varying thickness to compensate for thermal contraction of the lens member when molded in a predetermined manner. Specifically, the ordinary warped condition encountered with thermal contraction of the pressed glass article when initially formed is compensated for so as to permit subsequent heat sealing with a pressed glass reflector member by thermally fusing the glass material of both members in the sealing regions and without encountering the manufacturing defects now being experienced. The preferred embodiments illustrate such controlled thickness variation of the body section in the outer sealing rim region of a pressed glass lens member for both circular-shaped and rectangular-shaped lens configurations. Additionally, the rectangular-shaped pressed glass lens member embodiment illustrated can further include a molded projection provided on the back sealing surface of the rim region to further reduce unwanted deformation which otherwise occurs when the lens member is initially formed by pressing in glass molds.
