The method of patterning a conductive polymer includes forming a conductive polymer layer on a substrate, aligning a shadow mask above the conductive polymer layer, and forming a conductive polymer pattern area and an insulating area in the conductive polymer layer by radiating charged particle beams through the shadow mask.

Abstract: A mercury vapor discharge fluorescent lamp is provided having a phosphor layer that has a yttria-based red emitting rare earth phosphor. The phosphor layer is prepared from an aqueous phosphor slurry that is coated onto the inner surface of the glass envelope of the lamp, then baked in a lehring oven to vaporize or decompose non-phosphor components of the slurry to leave behind the finished phosphor layer. The phosphor slurry contains a non-ionizing thickener, preferably polyethylene oxide, but does not contain any calcium carbonate or carbonate salts. The phosphor layer includes a yttria-based red emitting rare earth phosphor.

Abstract: An organic layer (1) is applied to a transparent carrier (2) in such a way that different partial regions with different refractive indices are formed in the layer. Owing to deflection at the phase boundaries within the layer, fewer photons remain trapped in the layer as a result of wave-guiding losses than in the case of homogeneous layers.

Abstract: An electron emission thin-film with improved secondary electron emission characteristics compared with conventional ones, a plasma display panel including the electron emission thin-film, and their manufacturing methods. Using a vacuum deposition system, a protective layer that is an MgO thin-film is formed on a dielectric layer formed on a front glass substrate. At the time of deposition, angles that lines linking the central point of a target material for the protective layer respectively with the central point and both ends points of the front glass substrate form with the front glass substrate are exclusively in a range of 30 to 80 °. This enables at least some of MgO columnar crystals constituting the protective layer to have flat planes that are inclined with respect to the surface of the thinfilm.

Abstract: A method for manufacturing a display device of the present invention includes the steps of forming insulating barriers which surround electrode and project upward from the surface of the electrode, and bringing the whole substrate into contact with water after applying the solution including an acceptor in wet process. According to the present invention, an organic conductive layer can be uniformly formed over a substrate in wet process even if the substrate does not have a smooth surface and has distribution in wettability of the surface.

Abstract: A process of manufacture and an article produced by the process in the form of a lead glass substrate. The substrate is discretely marked during the manufacturing process by directing a flame upon it that is deficient in oxygen to provide a darkened or black marking in the glass surface. The invention is especially useful for marking electric lamps.

Abstract: A color cathode ray tube is disclosed having a front assembly with a shadow mask characterized by having circular apertures at the mask center, and apertures at least in the mask periphery increasingly elongated radially outwardly as a function of distance from the center. The elongation of the apertures is effective to reduce or eliminate the distortion of the deposits on the mask periphery produced by diffraction effects during photoscreening, and to form phosphor deposits compatible in size and shape with the electron beamlets. The screen of the tube according to the invention may have circular or near-circular phosphor deposits thereon. Tube types to which the invention can be applied include the conventional curved-screen/curved-mask tube, and the substantially flat faceplate tube that has a foil shadow mask suspended in tension a predetermined distance from the screening surface.

An apertured electrode plate is disposed adjacent to the base plate and its electrodes, and a face plate assembly is prepared by providing a glass plate and forming on one surface, in order, a large-area electrode and one or more insulating layers, after which an apertured insulating layer is formed thereon by a photo-etching process. The face plate assembly carrying the apertured insulating layer is assembled with the other parts of the panel, and the panel is processed to completion.

Abstract: A method is provided for making a lithium-sodium-antimony photocathode including the step of forming a base layer including antimony on a substrate. Sodium is then deposited onto the base layer at an elevated temperature to a first peak value of responsivity, thereby forming a sodium-antimony surface. Next, at room temperature, lithium is deposited onto the substrate containing the sodium-antimony surface until the lithium-sodium-antimony photocathode develops a hazy brown color. The photocathode is sensitized by heating the substrate to an elevated temperature until a second peak value of responsivity, greater than the first peak value, is obtained. Antimony, sodium and lithium are then alternately deposited on the photocathode in order to stabilize the second responsivity peak.
