Abstract:
A fluorescent lamp has an amalgam container settled inside an exhaust pipe extending from an end portion of a bulb to which electrodes are attached at both end portions. The amalgam container contains amalgam inside and has an opening portion through which the contained amalgam cannot go out and a part for determining the position of the amalgam, wherein the opening portion is located on the side where the exhaust pipe is cut and sealed. This configuration makes it possible to prevent the amalgam from outflowing into an exhaust equipment. In addition, the mercury vapor pressure is maintained optimally, and high luminous efficiency is obtained.

The front and rear reflectors may be spaced to create either a standing or treaveling eledtromagnetic wave to enhance the efificenty of the light transmission.
Abstract:
An electron field emission device is provided by placing a substrate in a reactor, heating the substrate and supplying a mixture of hydrogen and a carbon-containing gas at a concentration of about 8 to 13 per cent to the reactor while supplying energy to the mixture of gases near the substrate for a time to grow a first layer of carbon-based material to a thickness greater than about 0.5 micrometers, subsequently reducing the concentration of the carbon-containing gas and continuing to grow a second layer of carbon-based material, the second layer being much thicker than the first layer. The substrate is subsequently removed from the first layer and an electrode is applied to the second layer. The surface of the substrate may be patterned before growth of the first layer to produce a patterned surface on the field emission device. The device is free-standing and can be used as a cold cathode in a variety of electronic devices such as cathode ray tubes, amplifiers and traveling wave tubes.

A photocatalyst sterilizing lamp is constructed to include an UV lamp body and a photocatalyst coating coated on the surface of the lamp body, the lamp body having non-coating zones surrounded by the photocatalyst coating for the passing of ultraviolet light from the UV lamp body to activate the photocatalyst of the photocatalyst coating.
Abstract:
In a pixel circuit composing a digital-driven organic EL display device, an organic light emitting element which emits light by the supply of electric current, and two driving transistors for controlling the supply of electric current to the organic light emitting element are connected in series. The driving transistor functions as an electric current adjustment element which adjusts an electric current flowing through the organic light emitting element. When the electric current flowing through the organic light emitting element decreases by the degradation of the organic light emitting element, decrease in temperature and the like, the driving transistor acts for increasing the electric current.
Abstract:
In a sealing method of a top-emission organic light emitting element, in the case of using a method of filling with a sealing agent between a substrate mounted with pixels and an opposed substrate, the organic light-emitting element is degraded by ultraviolet rays when irradiation of the ultraviolet rays is performed toward the pixels in order to achieve ultraviolet curing of the sealing agent filling on the pixels. It is an object of the present invention to propose a method for avoiding this phenomenon to provide an organic light-emitting device with superior stability. In order for a sealing agent 13 filling on a pixel portion 14 to have a larger absorbance to ultraviolet rays, an ultraviolet-absorbent material is dispersed in a sealing agent to make an adjustment so that the absorbance of ultraviolet absorption wavelength of 400 nm or less becomes 1 or more.

The invention relates to a new design of discharge vessel for a discharge lamp, in which dielectrically impeded discharges are to be generated. In this case, a discharge vessel plate 1, 9 is, as it were, of two-fold design, specifically as a first discharge vessel plate 1 with an external electrode set and, in addition, as a stabilizing plate 9 outside the first discharge vessel plate 1.
Abstract:
As for the dual emission display device, since light is emitted to the opposite directions from a light emitting element, the both electrodes provided opposite to the light emitting element are transparent/translucent. Accordingly, difficulty in black display is created, and thus, the contrast would be reduced. That results from that the back of the display device can be seen through in black display, that is in the OFF state, since the both electrodes have transparency. Addressing the difficulty in black display with respect to an electronic device and the like including a dual emission display device achieving reduction in the thickness and light weighting, pure black display is performed by providing the dual emission display device part with a polarizing plate or a circularly polarizing plate. Further, the contrast can be improved.
Abstract:
Embossed microstructures within a substrate are used to create narrow and deep holes within that substrate. A carbon nanotube solution or mixture is then deposited over this substrate with the embossed holes. Shaking or vibrating the substrate will then cause the carbon nanotubes to fall into each of the holes in such a way that all of the nanotubes within a hole will be substantially parallel to the long axis of the hole. This structure can then be combined with a gate electrode and an anode to create a field emission display device.
