Abstract: A DC power supply 1 is connected with the DC-type high voltage generator 2 that boosts the power supply. A negative output terminal 3 and a positive output terminal 6 of the generator 2 are respectively connected to a cathode electrode 5 and an anode electrode 7. A dielectric sheet 4 with appropriate relative permittivity and certain range of volume resistivity is closely attached on the cathode electrode surface opposed to the anode electrode. The cathode electrode 5 together with the dielectric sheet 4 constitutes a DC-type dielectric barrier electrode 9. The power supply 1 and the generator 2 are disposed on an upper surface of a belt-type attachment 15, and the discharge electrode 9 and the anode electrode 7 are disposed on the lower surface thereof. The electrodes 9 and 7 become opposed to each other upon wrapping the attachment 15 around the affected part of a subject.

Abstract: A display apparatus includes an electroconductive member contacting with each of an electroconductive film and an electrode. The electroconductive member includes a resilient portion holding the electroconductive film between the relevant resilient portion and a second substrate while maintaining contact with the electroconductive film, and a resilient portion holding the electrode between the relevant resilient portion and the second substrate while maintaining contact with the electrode.

Abstract: To reduce the quantity of a noble gas, typically xenon, and improve the sk and vibration resistance of the quartz glass bulb upon possible movement of electrode support shafts (4, 4') in transport or handling, a support element (6, 6') is engaged against a constriction between the bulb portion (1) and the neck portions (2, 2') of the discharge vessel structure. A spiral spring (8), preferably of tungsten, is engaged against one or more ceramic, perferably aluminum oxide disks, backed up against a melt seal, and pressing the respective disk or disks against the support element. The ceramic disks are loosely seated on the electrode shaft and located within the neck portions with clearance, so that, upon operation of the lamp, and expansion due to heating of the ceramic disks, the stability of the arc is improved and ignition is facilitated due to the lower fill pressure of the noble gas.

Abstract: A joint for electrodes with a peg securing electrode members together produces an electrode joint of superior strength, and with resistance to thermal, and mechanical stress which tend to loosen the joint.

Abstract: To improve the high-voltage flash-over characteristics of high-pressure dharge lamps (1), and especially to prevent flash-over between terminal leads emanating from the lamp bulb and extending into a lamp base (14), the lamp base which is formed with a cup-shaped opening (13) has an insert pad (18) placed therein of fibrous web, pile, fleece or mat material, made of ceramic, quartz or glass fibers. In manufacture, the fibers are compressed, thereby fitting tightly against the terminal end, typically a pinch or press seal, of the discharge lamp bulb, and thereby substantially increasing the high voltage flash-over resistance between the terminal leads and permitting hot re-ignition of the lamp, which may require pulses of between 15 to 20 kV.

Abstract: An incandescent lamp has an envelope within which is enclosed an incandescent filament. The incandescent filament is surrounded by a tubular element with open ends. The element transmits visible radiation, and reduces but does not eliminate convection around the filament. This reduces the rate at which evaporated filament material is carried away from the filament and deposited elsewhere within the lamp. If desired, a filter coating may be placed on the element for reflecting infrared radiation back to the filament and transmitting visible radiation away from the filament and out of the lamp. The element may engage the filament leads for mounting purposes.
