Abstract: Systems and methods for cleaning emitter electrodes of air conditioner systems are provided. The air conditioning system includes an emitter electrode, a collector electrode and a high voltage generator to provide a high voltage potential difference between the emitter and collector electrodes. The system also includes a cleaning member having a channel through which the emitter electrode passes. A plunger mechanism and a spring, or a lever and a fulcrum, are used to force the cleaning member to travel upward along the emitter electrode to thereby frictionally removing debris from the emitter electrode. This description is not intended to be a complete description of, or limit the scope of, the invention. Other features, aspects, and objects of the invention can be obtained from a review of the specification, the figures and the claims.

Abstract: A plurality of discharge electrodes are grouped for respective gas passages that are defined by collecting electrodes (11-15). The discharge electrodes in each group are connected to a common power supply unit for receiving output voltage through a diode provided for each group and are connected to a spark electrode (21). The spark electrode is positioned such that it sparks between a hammer (20) in a passageway of the hammer upon striking. Each group of the discharge electrodes has a ground unit to be grounded just before the collecting electrodes on both sides thereof are struck.

Abstract: A method of producing a durable photomask comprising,Forming a silver image pattern in a silver halide emulsion layer on a glass support by imagewise exposing the emulsion layer followed by development,Removing pattern-like the silver halide emulsion layer utilizing the difference in property between the silver image-containing portions and the non-silver image-containing portions of the emulsion layer to partially uncover the surface of the glass support at the portions where the emulsion layer was removed,Applying a silver ion-supplying material and/or a copper ion-supplying material on the glass support to form a layer of the ion-supplying material, andHeating the glass support at a high temperature to diffuse the metal ions into the surface of the glass support at the uncovered surface portions of the glass support.

Abstract: The method and decorated article comprising glassware such as bottles and drinking tumblers is set forth. Halftone printing of a plurality of different colors is employed to produce a composite graphic display on the surface of the glass. Precise alignment is utilized in order to register the halftone printing screens for each color that is deposited on the glass surface. The opaque enamels employed in the decorative process are carefully balanced with respect to each other to obtain the desired color hues. The deposition angles for the alignment of the halftone dots is controlled to minimize the undesirable moire effect.

Abstract: This invention relates to a method for reducing the amount of ambient light which is reflected by the phosphor located on the inside surface of a color television picture tube face plate. More particularly, the invention contemplates placing a green-absorbing optical filter in front of the red and blue phosphor areas. The filter is produced from gold-containing glass.In carrying out the preferred embodiment of the invention, an opaque mask having holes of the desired shape and in the proper pattern is placed near a CeO.sub.2 -activated, photosensitive gold-containing glass, the glass is exposed through the mask to ultra-violet radiation, and thereafter subjected to a prescribed heat treatment to yield the color filters. The phosphors are applied in dot or slot-shaped configurations in the conventional manner with the blue and red phosphors being placed over the filters and the green phosphor in the clear area.

Abstract: The present invention is directed to a method for producing patterned color-triad arrays in glass for use in color television picture tubes, such arrays being capable of acting as spectrally-selective filters and to provide the desired color information when the television tube is operating. The color-triad arrays are produced by sequentially or simultaneously exposing a polychromatic glass through an electron shadow mask to high energy or actinic radiation and thereafter following the heat treatment and re-exposure practice known to develop colors within polychromatic glass. The filtering action provided by the color triads integrally present within the glass can enhance the contrast of the color image produced. Also, the presence of the color triads in the glass permits the use of a single "white" phosphor, rather than a red, a green and a blue phosphor as are presently used in the conventional color television picture tube.

Abstract: A cathode ray storage tube provided with a storage target having a multiplicity of segments of the collector electrode extending through the dielectric layer of the storage target. These segments comprise glass beads secured together and to a surface of an insulating support plate, a conductive collector electrode coating is applied onto the support plate surface and glass bead segments and then the storage dielectric layer is applied thereover which has proper thickness so that the segments extend above the dielectric thereby providing collector areas for collecting secondary emitted electrons from the dielectric.

Abstract: A process for forming a color cathode ray tube screen structure, having means for enhancing the absorption of ambient light and providing improvement in the contrast of the image display involves the deposition of three superimposed substantially continuous window-defining layers of optical filter materials. The primary, secondary and tertiary filter layers have discretely disposed window areas formed therein to expose a pattern of filter areas representing the respective filter materials. The filter windows are of a shaping similar to that of the apertures in a spatially related pattern mask member. Each window exhibits a uniform periphery free of indentations, being so defined by a uniform opaque interstitial encompassment homogeneously made up of the three distinct layers of filter materials.
