Abstract: A microwave plasma burner in which a high temperature plasma is generated. The microwave plasma burner includes a wave inducing tube for receiving and guiding microwaves from an antenna of a magnetron within a wave guide resonator, so as to generate a high temperature plasma by causing vibrations of an injected gas by the help of the microwaves while discharging the injected gas. The microwave plasma burner according to the present invention gives the following effects. A strong high temperature plasma can be generated with a structure not involving vacuum. The flames are generated by the heat which is generated by the vibrations of air, and therefore, a separate igniting device is not required. High temperature flames are generated, and therefore, the burner of the present invention can be used for welding and cutting. A complete combustion occurs due to the heat which is generated by the vibrations, and therefore, any air pollution can be prevented.

Abstract: The present invention relates to multi-layered organic light emitting diode devices having hole-injection and/or hole-transport layers comprising aryl amine compounds with relatively high glass transition temperatures (i.e., thermostable aryl amine compounds). Such multi-layered OLED devices allow for a staircase change in the energy difference of holes and electrons as they migrate from the electrodes toward the emitter layer, resulting in a lower operating voltage and a high quantum yield of luminescence for a given current density. The present invention also relates to microdisplay devices comprising multi-layered organic light emitting diode devices having hole-injection and/or hole-transport layers comprising thermostable aryl amine compounds.

Abstract: Scanning probe apparatus, including a tip-electrode which is coupled to be held at a substantially ground potential, a counter-electrode which is positioned in proximity to the tip-electrode, a voltage source, coupled to maintain the counter-electrode at a non-ground potential, and positioning-instrumentation, which is adapted to maintain the tip-electrode at a suitable position relative to a surface of a ferroelectric sample located in a space between the tip-electrode and the counter-electrode. The apparatus generates an electric field in the ferroelectric sample greater than a coercive field of the sample.

Abstract: The present invention is directed to an apparatus and method of solder-sealing an active matrix OLED display using a monochromatic solid-state laser beam (1). The solder-sealing apparatus comprises a cover assembly (13) adapted to be positioned over at least one OLED (11) on a substrate (10), a sealing band (12) surrounding each OLED, a chuck assembly (20) with an array of heat sinks (21) that align with the OLEDs, a pick-up assembly (30) with at least one aperture (33), and a flange assembly (132) to which a solder pre-form (133) is secured. The chuck assembly (20) receives, aligns and orients the substrate (10). A vacuum is then applied through each aperture (33) to align and hold the cover assembly (13) in place. The sealing band (12) and solder pre-form (133) are aligned and pressed together by the pick-up assembly (30), and the focused laser beam (1) is projected through the chuck assembly to seal the OLEDs (11) within the cover assembly (13).

Abstract: An integrated organic light emitting diode (OLED) color display device is disclosed. The OLED display device comprises at least one pixel element (10) capable of emitting visible light of varying wavelengths. Pixel element (10) may comprise: a substrate (100), an addressable two-dimensional matrix of organic light emitting diodes (120) that emits monochrome light, a color conversion matrix element (110) capable of absorbing the monochrome light and re-emitting that light at different wavelengths, and cover element (130). Color conversion matrix element (110) may further comprise at least one red color converting subelement (111), at least one green color converting subelement (112), and at least one blue color converting subelement (113). The color converting subelements (111, 112, and 113) may further comprise semiconductor nanocrystals (140) uniformly dispersed in a transparent organic binding material (150).

Abstract: Specially conceived for slides (1) which run along a track (2), having a housing (4) which is slanted in relation to the said track, a housing in which a guide (3) operates, also slanted, in a way that during the entrance of the guide, the slide (1) moves in one direction on the track (2) and on exiting it does so in the opposite direction, the retainer consists of a rod (5) which is housed in an orifice (6) of the slide perpendicular to the track (2) and which lines up with a blind orifice (10) on the track, precisely at the moment when the guide (3) exits the slide (1), the rod being aided by a spring (11) which tends to cause it to protrude constantly on the track (2) and against whose spring operates a rocker arm (14) which, also tending to enter the housing (4) of the slide, is activated by the same guide (3) when it is located in the housing of the slide.

Abstract: An air freshener dispenser having a transparent outer container. A detachably mounted top has one or more openings to allow circulation. A detachable insert is suspended in the outer container and thus floats in the outer container above the outer container's bottom. Additional decorative elements may be positioned between the outer container and the insert. An intermediate decorative insert can be removably positioned between the outer container and the transparent or translucent insert.

Abstract: A toy top comprises a body having an external surface with at least one external cavity and at least one extendable protrusion; in a static position, the protrusion is situated within the cavity and in a spinning motion, the protrusion is in an extended position from the cavity.

Abstract: A device for comminuting material comprising first and second mating sections. The mating sections when mated form an enclosed interior chamber with the first and second sections capable of movement relative to each other. The first mating section has a first set of a plurality of pins, which extend from a base of the first mating section and into the interior of the chamber. Similarly, the second mating section has a second set of a plurality of pins extending from a base of the second mating section and into the interior of the chamber. The pins from the first mating section interdigitate with the second set of a plurality of pins when the first and second mating sections are mated, wherein movement of the first and second mating sections relative to one another causes comminution of the material when placed in the chamber. The pins have varying cross-sectional shapes including circular, triangular, and hexagonal.

Abstract: The present invention is a boat mooring system for stabilizing a boat while docked which allows the effective length of the mooring line to vary for substantially greater distances than that of the prior art. The boat mooring system contains a multi pulley arrangement such that a small movement in a spring tensioning device results in a substantial change in the effective length of the mooring line. Thus, a change in tide, or weather conditions results in a substantial compensating effect.

Abstract: A method is provided for obtaining fine powders having narrow particle size range from non-conducting solids comprising the steps of: 1) creating an electrostatic charge on particles of a solid mixture formed by mechanical means, 2) grinding the mixture and neutralizing the electrostatic charge during grinding with a potential sufficient to create a corona discharge, 3) separating the powder according to particle size, and 4) collecting the finely ground finished powder product. The method is applicable to the manufacture of high quality cement powders.

Abstract: A germicidal UV chamber for use on air passing through a duct system, such as a central air system which replace one or more sections of the duct and, in essence, becomes part of the duct work. Each chamber is in the form of one or more ellipsoid sections which focus the energy uniformly throughout the chamber. The inlet and exit passages from the chamber are a grill formed from truncated elliptical concentric rings. Also positioned in the chamber is an ultraviolet transparent conduit through which a liquid such as water passes and is also germicidally cleansed. The conduit may very in diameter to retain UV energy in the conduit.
