Abstract:
A gas discharge tube 10 of the present invention generates an electric discharge between an anode part 24 and a cathode part 52 disposed inside a sealed container 12 in which gas has been sealed. The gas discharge tube 10 includes an electric discharge path restricting part 28 which is cylindrical and disposed between the anode part and the cathode part, and which has a throughhole 46 for narrowing an electric discharge path between the anode part and the cathode part; and a supporting part 30 which supports the electric discharge path restricting part and which is electric insulating. The electric discharge path restricting part is provided at its tip portion with a projecting part 44 which is cylindrical and projects toward the cathode part side. Letting the outer diameter and height of the projecting part 44 be “D” and “H,” respectively, then D/H is in the range of 0.5 to 2.0. With this structure, it is possible to generate an intense electric field in the vicinity of the tip of the projecting part. This can decrease a startup voltage, thereby ensuring the generation of an electric discharge.

Disclosed herein is a light source device. The light source device includes a front transparent substrate, a rear substrate, a plurality of partitions, and fluorescent material. The rear substrate is configured to face the front transparent substrate with a discharge space disposed therebetween. The partitions are arranged between the front transparent substrate and the rear substrate to divide the discharge space into a plurality of discharge channels. The fluorescent material is applied on the inside of the discharge space. Meanwhile, the partitions are formed such that the ratio of the radius of curvature R of each partition to the width W of the partition, that is, R/W, ranges from 0.1 to 4.

Abstract:
A method of forming a bank that partitions a region for forming a film pattern made of a functional liquid, includes: forming a bank film made of a photo resist by applying a photo resist liquid onto a substrate and drying the photo resist liquid; performing a lyophobic treatment for the bank film by using a lyophobic treatment gas and plasma; reducing a lyophobic property by selectively applying ultraviolet rays to the bank film after the lyophobic treatment with a mask; selectively exposing the bank film after the lyophobic treatment to light with the mask; developing and patterning the bank film after reducing the lyophobic property and exposing the bank film to light so as to form the bank; wherein the lyophobic property is reduced and the bank film is exposed to light continuously or at the same time with the same mask.
Abstract:
A discharge lamp disposed in a projecting device is provided. The discharge lamp includes a housing, a discharge vessel and an ultraviolet (UV) source. The discharge vessel having a first axis is filled with a gas and disposed in the housing. The ultraviolet source disposed at a predetermined distance from the first axis for exciting the gas so as to generate a beam.
Abstract:
Panel comprising an array of barrier ribs each having a base resting on a plate and a top in contact with another plate that includes at least two arrays of coplanar electrodes each preferably having a constant width. According to the invention, these barrier ribs have, at their top, a low-permittivity region of thickness greater than 3 μm and less than or equal to one fifth of their total height, which has a mean dielectric permittivity at least three times smaller than the dielectric permittivity of these barrier ribs measured at their base. Thanks to the invention, the confinement of the plasma discharges far from the barrier ribs is substantially improved.
Abstract:
A ceramic arc tube for a metal halide discharge lamp is described wherein the lower end well of the arc tube has an internal barrier ridge which substantially prevents migration of the metal halide condensate into the central region of the discharge chamber during vertical operation. The use of the ridge reduces fluctuation in the color temperature of vertically operated lamps and improves efficacy.
