  • Publication number: 20150002966
    Abstract: The invention provides a method of forming an electric field gap device, such as a lateral field emission ESD protection structure, in which a cathode layer is formed between dielectric layers. Anode channels are formed and they are lined with a sacrificial dielectric layer. Conductive anode pillars are formed in the anode channels, and then the sacrificial dielectric layer is etched away in the vicinity of the anode pillars. The etching leaves a suspended portion of the cathode layer which defines a lateral gap to an adjacent anode pillar. This portion has a sharp end face defined by the corners of the cathode layer and the lateral gap can be defined accurately as it corresponds to the thickness of the sacrificial dielectric layer.

  • Patent number: 6966811
    Abstract: An incandescent halogen lamp used in connection with a vehicle headlamp system in which stray light attributable to reflection off of internal lamp components is reduced while the structural integrity of the lamp is maintained. The halogen lamp includes two filaments, several lead wires, and a support bridge all sealed within a glass envelope. Each filament is connected at its outermost end to a flattened end portion of a lead wire which extends along the length of the filament from near the support bridge to the upper end of the filament. The flattened outer ends of the lead wires have a narrow profile that is in alignment with the direction of illumination of light from their respective filaments. This arrangement reduces the surface area that could otherwise interfere with light emitted by the filaments, and thereby reduces the overall stray light produced by the lamp. The flattened outer ends can have a roughened surface to further help reduce the amount of light reflected off the lead wires.

    Abstract: A method and the associated apparatus for alignment and assembly of microlenses and microcolumns in which aligning structures such as rigid fibers are used to precisely align multiple microlens components. Alignment openings are formed in the microlens components and standard optical fibers are threaded through the openings in each microlens component as they are stacked. The fibers provide sufficient stiffness and stability to the structure to precisely align the apertures of the microlens components and thereby allow for increased assembly efficiency over traditional microlens and microcolumn bonding techniques.

  • Patent number: 6137228
    Abstract: A method for manufacturing a metal halide lamp in which tungsten coils are made to have diameters wider than the outer diameters of electrodes, and to have a coil pitch sufficient to prevent molten quartz glass from entering therebetween; and after the tungsten coils have been fixed around the electrodes, the pitch of the tungsten coils on the sides of the electrodes which are nearest molybdenum foils is extended by dragging a part of the tungsten coils toward the discharge ends of the electrodes to fix it tightly around the electrodes. As a result, when sealing is performed with quartz glass bulb, gaps between the electrodes and the glass bulb are provided on the discharge sides of the electrodes, whereby it can be prevented to occur cracks in the quartz glass bulb due to the thermal expansion of the electrodes; and on the molybdenum foil sides of the electrodes, the quartz glass bulb contacts the electrodes, thereby preventing peeling-off and accumulation of sealed material.
