Abstract:
An enclosure having a front substrate (11) provided with a display surface and a rear substrate disposed opposite to the front substrate is provided. The front substrate has a metal back (20) formed by being overlapped on the display surface and getter film (22) formed of at least two types of active metal on the metal back. The getter film is formed by depositing a plurality of getter materials. The invention can improve the gas adsorption characteristics of a getter film to characteristics obtained by combining a plurality of getter materials. Accordingly, an image display unit capable of providing a broader design range of getter film characteristics, maintaining a high vacuum degree inside an enclosure, and keeping high display performance over an extended period; and a production method therefore can be obtained.
Abstract:
An image display unit having a structure in which a heat−resisting fine particle layer is formed on a metal back layer formed on a phosphor layer, and a getter layer is deposited/formed on the heat−resisting fine particle layer by vapor−depositing. The fine particle layer is desirably formed in a specified pattern, and a filmy getter layer is formed in a pattern complementary to the former pattern. The average particle size of heat−resisting fine particles which may use SiO 2 , TiO 2 , Al 2 O 3 , Fe 2 O 3 is 5 nm−30 μm. Since abnormal discharging is restricted, the destruction and deterioration of an electron emitting element and a fluorescent surface are prevented to provide a high−brightness, high−grade display.

Abstract:
A non−evaporation type getter which is excellent in gettering effect, can keep in a high vacuum state the interior of an air−tight vessel in a display unit especially a flat display unit, is easy to mount, and is not likely to contaminate the interior; a display unit provided with the getter; and production methods for them. The non−evaporation type getter (20) mainly contains at least any one element out of Ti, Zr, Al, V, Fe, and is provided with a compact formed by powder injection molding, the compact being composed of a porous element having a porosity of 10−30%.
Abstract:
The invention relates to a field emission display constructed using an array of fibers (15) and an orthogonal array of emitter electrodes (40). Each fiber (15) in the fiber array contains an extraction electrode (10), a high voltage electrode (20) and a phosphor layer (30). The array of emitter electrodes consists of carbon nanotube emitters attached to conductive electrodes (40). The emitter electrodes (40) are separated using non-conductive fibers (50). A getter material in the form of a wire (55) is placed within the array of emitter electrodes (40) to maintain a high vacuum within the display.
Abstract:
A durable electron source exhibiting uniform or less varying characteristics is provided. A plurality of row wires (8) intersect with a plurality of column wires (6) on a substrate (1). An electron-emitting element consisting of element electrodes (2, 3), conductive film (4) and an electron emitter (5) is provided at each intersection of the row wires (8) and column wires (6). Getters (9) are arranged on some of the row wires (8). The column wires (6) are connected with regulated current sources (221a, 221b, 221c) capable of supplying desired current. The row wires (8) are connected with voltage source means that includes a voltage source (223) and a switching circuit (222) for selecting the row wires (8) while sequentially scanning them.

A vacuum device is provided with a getter device. The getter device comprises a deflector. The deflector is provided with raised and/or depressed portions, such as ribs or undulations in the direction of diffusion of the getter material.
Abstract:
An ion pump permits the continuous evacuation of a small-envelope vacuum chamber while drawing a relatively small amount of power (micro watts). In a preferred embodiment, the present ion pump occupies a space enclosed by a first surface of chamber (1), a second surface of chamber (2), a side of chamber (3), and an optically-opaque shield (4). The small size and integration of the ion pump within the vacuum chamber enables the device in which the vacuum chamber is incorporated to be portable and to retain its original dimensions.
Abstract:
An imaging apparatus (100) for providing an image from a display (106) to an observer (101), comprising: a display (106) generating an optical output, an imaging surface member (109) constructed and arranged for viewing by said observer, and a scanning mirror/lens assembly (102) optically interposed between the display and the imaging surface member, and constructed and arranged to motively repetitively scan the display, generate a scanned image, and transmit the scanned image to the imaging surface member, for viewing of the scanned image. Various field emitter display designs and subassemblies are described, which may be usefully employed in such imaging apparatus.
Abstract:
There is provided a pipe in a solar thermal power plant, the pipe comprising an inner tube configured for carrying a heated heat transfer fluid, an outer tube surrounding the inner tube, wherein the space between the inner and outer tube is evacuated, and a getter restraint structure configured for maintaining getters in a predetermined position. The getter restraint structure is in contact with the outer tube and otherwise entirely free of contact with the inner tube and/or is in thermal isolation from the inner tube.
