  • Patent number: 6132818
    Abstract: Prepared is a transcribing plate comprising a glass substrate and a chromium film formed on a surface of the glass substrate. The transcribing plate is disposed on a surface of an object (for example, a glass substrate of a plasma display panel) such that the chromium film faces the surface of the object. The transcribing plate is pressed toward the object, if necessary. A predetermined identification code pattern is drawn on the transcribing plate by a YAG laser beam. The laser beam reaches, through the glass plate, the chromium film to heat it. Chromium vapors generated by the heating are deposited on the surface of the object. This means that the identification code pattern is transcribed on the object surface.

  • Patent number: 6123985
    Abstract: A membrane-actuated charge controlled mirror (CCM) that exhibits increased deflection range, reduced beam current and improved electrostatic stability is fabricated using a combination of flat panel manufacturing along with traditional MEMS techniques. More specifically, a unique combination of five masking layers is used to fabricate a number of CCMs on a large glass panel. At the completion of the MEMS processing, the glass panel is diced into individual CCMs. Thereafter, the polymer mirror and membrane release layers are simultaneously released through vent holes in the membrane to leave the free-standing CCM.

  • Patent number: 6066357
    Abstract: Methods of making a full-color organic light-emitting display are disclosed. The methods include ink-jet printing of fluorescent dopants selected to produce red, green, or blue light emission from designated subpixels of the display. The dopants are printed sequentially from ink-jet printing compositions which permit printing of dopant layers over a light-emitting layer containing a host material selected to provide host light emission in a blue spectral region. The dopants are diffused from the dopant layer into the light-emitting layer by exposing the light-emitting layer and the dopant layers to vapor of a fluid or fluid mixture. When an ink-jet printing composition is formulated with a printing fluid having fluid vapors which promote dopant diffusion, the steps of ink-jet printing and diffusing of dopants can be combined to form a selectively doped light-emitting layer.

    Abstract: A method of treating earthenware bodies to enhance resistance to freezing and to assist the application of decals and the like thereto comprises treating the bodies with a liquid medium containing a water-repellent material such as silicone. In a subsequent drying step, the bulk of the liquid medium is removed while leaving the water-repellent material deposited in the pores of the earthenware body. In this way, subsequent entry of water and freezing and cracking is resisted. It has also been discovered that the treatment also enchances the ability of the earthenware surface to receive decals and the like without the need for glazing and an additional firing step.

    Abstract: A process suitable for forming multi-layer (up to at least several hundred layers) monotonic/linear variable/wedge filter coatings on a single substrate surface and for forming monolithic filter assemblies which incorporate such filters, is disclosed along with the designs for such filters. The monolithic process uses radially variable filter fabrication techniques in combination with ion-assisted deposition to form stress controlled, radially variable filter coatings of the desired varied optical profile, preferably using high and low index materials stich as tantala and silica. Stress is minimized by balancing the amount of ion assist and the coating rate. Slices are cut radially from the substrate to form quasi-linear variable filters. Other coatings such as, but not limited to, a wide band hot mirror can be formed on the opposite surface of the substrate from the radially variable LVF method.

  • Patent number: 5834055
    Abstract: A method for co-diffusing titanium and aluminum into a single-crystal lithium niobate substrate and guided wave devices produced therefrom are provided. Titanium diffused into the substrate forms a light guiding region. A layer of aluminum deposited over the light guiding region and diffused into the substrate buries the light guiding region below the substrate surface. In an alternate embodiment, a layer of aluminum forms a mode shaping region which surrounds the light guiding region on two sides. The mode shaping region has ordinary and extraordinary indices of refraction less than the substrate such that mode mismatch between a device fabricated thereby and an externally coupled fiber is reduced. The aluminum can be diffused into LiNbO.sub.3 at a much lower temperature without affecting diffused titanium guides. Preferably, the titanium diffusion occurs at about 1000.degree. to about 1100.degree. C. while further aluminum diffusion occurs at a lower temperature in the range of about 900.degree. to 950.

The surface composition of at least one region of a target surface of the workpiece is altered to produce a catalytically-activated region on the target surface. At least one region of the target surface disjoint from the catalytically-activated region is a catalytically-inactive region.

On this adhesive layer (4) barrier layer (6) protecting the latter is deposited and the barrier layer is provided with subsequent solder layer (7). These solder layers (7) are bonded with sheet (8) that edges structural and/or light element (1) on the edge in a gastight manner.

  • Patent number: 5211328
    Abstract: A method of precisely depositing accurately defined quantities of solder onto high density circuit patterns on a substrate without use of a solder mask or the like wherein solder paste is originally deposited within a precisely defined transfer member (e.g., graphite block having holes drilled therein), the transfer member then being aligned relative to the respective circuitry such that when both block and substrate are heated, solder flow and deposition will occur without the use of a solder mask or the like. Following deposition, a second circuit member (e.g., flexible circuit) may be electrically coupled to the substrate's conductors, the deposited solder providing the coupling medium. Hydrogen gas may be used during the heating of the paste and also during the soldering of the flexible circuit to the substrate.

  • Patent number: 5082703
    Abstract: A sign with an etched or embossed appearance comprises a transparent substrate on which an extraordinarily thick ridge of viscous ink has been deposited to form a design. For an embossed appearance, the ridge of ink is uniformly smooth. For an etched appearance, the ridge of ink is formed with a textured pattern. A sheet having a thin layer of adhesive on one side is pressed onto the substrate over the ridge of ink to adhear the sheet to the substrate and conform the sheet to the ridge to give the appropriate appearance for the design. Alternatively, the sheet may be replaced by a solidified stratum of a metallic-based solution or powder which may be sprayed or electroplated, respectively, onto the substrate.

  • Patent number: 5034244
    Abstract: Heat resistant substrates of glass, metal or ceramic are coated by applying onto the substrate a layer of radiation-curable and firable printing ink containing an inorganic ceramic color, curing the layer by exposure to radiation and applying onto the substrate on or adjacent to the radiation curable ink a firable printing ink in the form of a gel containing a precious metal. The coatings may be applied at successive stations of a single automatically operated printing machine, after which the substrates can be fired.

  • Patent number: 4894278
    Abstract: A decorative mirror having a reflective silver layer deposited on a transparent sheet. A substance which reacts with silver is applied to the silver layer to create randomly distributed areas containing reaction products including non-metallic silver where the visible light reflectance of the mirror is modified or interrupted. In order to manufacture the mirror, a transparent sheet is wetted with a silvering solution to form a reflective silver layer, and while the sheet is still wet with the silvering solution the sheet is contacted with randomly distributed droplets of a solution of a substance which reacts with silver, the two solutions being made up using different solvents. The substance which reacts with silver may be a tin compound in an alcoholic solution, the silvering being effected with an aqueous solution. The silver layer whose reflective properties have been modified may be overcoated with a second silver layer, and the whole protected with further layers, for example of copper and paint.
