  • Patent number: 6609941
    Abstract: An vehicle lamp assembling apparatus including a jig which supports a lamp component, an apparatus main body having disposed thereon positioning and fastening mechanisms (plungers and engagement holes) for positioning and fastening the jig to the apparatus main body. Some equipment (contact units) is disposed on the apparatus main body, and/or on the jig, for carrying out a predetermined processing, such as working or inspection, on the lamp component supported by the jig. Further, a control part is disposed on the apparatus main body, for drive control of the equipment. An ID plate that stores processing information, such as driving procedures and driving amount of the equipment, is disposed on the jig, whereas a non-contact memory reader is disposed on the apparatus main body so as to oppose the ID plate when the jig is fastened to the apparatus main body. The control part drives the equipment based on the processing information read from the ID plate via the memory reader.

  • Patent number: 6607414
    Abstract: A novel technique utilizing the precision of printed circuit board design and the physical versatility of thin, flexible substrates is disclosed to produce a new type of ion reflector. A precisely defined series of thin conductive strips (traces) are etched onto a flat, flexible circuit board substrate. Preferably, the thin conductive strips are further apart at one end of the substrate and get increasingly closer towards the other end of the substrate. The flexible substrate is then rolled into a tube to form the reflector body, with the conductive strips forming the rings of the ion reflector. The spacing between the traces, and hence the ring spacing, can be readily varied by adjusting the conductor pattern on the substrate sheet during the etching process. By adjusting the spacing between the rings, the characteristics of the field created by the reflectron can be easily customized to the needs of the user.

  • Patent number: 6607415
    Abstract: A method for fabricating tiny field emitter tips across the surface of a substrate. A substrate is first exposed to reactive molecular, ionic, or free radical species to produce nanoclusters within a thin surface layer of the substrate. The substrate may then be thermally annealed to produce regularly sized and interspaced nanoclusters. Finally, the substrate is etched to produce the field emitter tips.

  • Patent number: 6604971
    Abstract: A method of manufacturing an LED lamp includes dispersing color correction particles throughout a suspension media to a viscosity of substantially 2000 cP. In the case of correcting blue GaN LEDs to white light, the particles to be blended are phosphorus having a diameter of less than 20 microns. An LED die is mounted onto a stage and a nano-liter pipette is arranged such that an interface separation of approximately 1 millimeter is achieved between the tip of the pipette and the surface of the LED die. Once the relatively viscous suspension media covers the LED die, ultraviolet light is directed towards the suspension media to cure it. Heat is then applied to further cure the suspension media until solid as observed under a microscope.

  • Patent number: 6602104
    Abstract: An arc lamp comprises nine component parts that are brought together in three brazes and one TIG-weld to result in a finished product. An anode assembly is brazed with the rest of a body sub-assembly in one step instead of two. A single-bar cathode-support strut is brazed together as one step. A window flange and a sapphire output window are brazed together with the product of the strut braze step in a mounted-cathode-braze step. A copper-tube fill tubulation, a kovar sleeve, a ceramic reflector body, an anode flange, and a tungsten anode are all brazed together in a “body-braze” step. The products of the mounted-cathode-braze step and body-braze step are tungsten-inert-gas (TIG) welded together in a final welding step. A lamp is finished by filling it with xenon gas and pinching off the tubulation.

  • Patent number: 6595820
    Abstract: A field emitter cell includes a thin film edge emitter normal to a gate layer. The field emitter is a multilayer structure including a low work function material sandwiched between two protective layers. The field emitter may be fabricated from a composite starting structure including a conductive substrate layer, an insulation layer, a standoff layer and a gate layer, with a perforation extending from the gate layer into the substrate layer. The emitter material is conformally deposited by chemical beam deposition along the sidewalls of the perforation. Alternatively, the starting material may be a conductive substrate having a protrusion thereon. The emitter layer, standoff layer, insulation layer, and gate layer are sequentially deposited, and the unwanted portions of each are preferentially removed to provide the desired structure.

  • Patent number: 6592419
    Abstract: A process for fabricating a flat panel display having a faceplate and a baseplate comprises creating an electric field between the faceplate and the baseplate to temporarily attract the faceplate to the baseplate and attaching the baseplate and faceplate to each other while the electric field is present. Capacitor(s) are formed on the faceplate and/or baseplate of a flat panel display such that a portion of the capacitor(s) is formed on the faceplate and is aligned with the pixel matrix and/or a portion of the capacitor(s) is formed on the baseplate and is aligned with the cathode member. The first and second portions of the capacitor(s) are energized to opposite polarity voltages, and an electric field is generated which attracts and aligns the two portions of the capacitor(s) to each other. When the two portions of the capacitor(s) are aligned and attracted to each other, the pixel matrix and cathode assembly are inherently aligned with each other.

  • Patent number: 6592420
    Abstract: A glass substrate manufacturing method and a color cathode ray tube manufacturing method manufactures a front substrate on which a phosphor layer is formed. In an application process a phosphor slurry of one color is applied onto an inner surface of a glass substrate on which a phosphor pattern in at least one color has already been formed. Then, in a spreading process, the glass substrate is rotated about an axis located at the approximate center of the inner surface to make the phosphor slurry spread out over its inner surface. Following this, in a draining process the glass substrate is tilted to a first tilt angle of more than 90° to drain excess slurry off the inner surface of the glass substrate, a tilt angle being formed between a vertical axis and an axis orthogonal to an outer surface of the glass substrate. In a spinning process the glass substrate is returned to a second tilt angle smaller than the first tilt angle, and rotated.
