The present invention provides a plasma generating system that includes at least one nozzle. The nozzle includes: a housing having a cavity formed therein, where the cavity forms a gas flow passageway; a rod-shaped conductor disposed in the cavity and operative to transmit microwave energy along the surface thereof so that the microwave energy excites gas flowing through the cavity; and means for moving a proximal end of the rod-shaped conductor relative to a downstream end of the gas flow passageway.

An injection molding apparatus capable of minimizing cracks at the corners of a mold is provided. The injection molding apparatus includes first and second molds that mate with each other to define a molding cavity, a stationary member that supports the first mold, a movable member that supports the second mold and moves backwards and forwards together with the second mold, and a plurality of pressing members installed around the first mold so as to press a periphery of the first mold toward the molding cavity by a pressing force of the movable member when the first mold is mated with the second mold.
Abstract:
A power adaptor for converting AC/DC current to DC current and providing the converted DC current to a portable device. The power adaptor includes a converter and switching means. The converter includes input ports for receiving the input current therethrough and output ports for flowing the output current therethrough. The switching means are coupled to the input ports and operative to control the flow of the input current. The switching means are adapted to be connected to and operated by the portable device such that the input current flows only when the portable device is coupled to the power adaptor.
Abstract:
An arterio-venous graft includes an implantable tubular member and a flow regulator. The implantable tubular member has a first end and a second end generally opposite the first end. The flow regulator is between the first end and the second end. The flow regulator is configured to regulate fluid flow between the first end and the second end. A method of regulating pressure in an arterio-venous graft includes reversibly adjusting a cross-sectional area of the graft. A method of fluidly coupling an artery and a vein includes connecting a first end of an implantable tubular member to the artery and connecting a second end of the implantable tubular member to the vein. A cross-sectional area of the implantable tubular member is reversibly adjustable.
Abstract:
A display substrate includes a base substrate, a signal line, a thin-film transistor (“TFT”), a pixel electrode, a color filter and a light-blocking part. The signal line and the TFT are formed on the base substrate. The TFT is electrically connected to the signal line. The pixel electrode is formed in a unit pixel area of the base substrate and is electrically connected to the TFT. The color filter is formed in the unit pixel area. The light-blocking part includes an organic pattern formed on the base substrate and a light-blocking pattern formed on the organic pattern. The organic pattern covers the TFT and is formed along a longitudinal axis of the signal line to define at least a portion of a periphery of the color filter. A size and a shape of the light-blocking pattern are substantially the same as a size and a shape of the organic pattern.
Abstract:
An indoor unit of an air conditioner capable of enhancing heat exchange efficiency and reducing noise/vibration is provided. The indoor unit includes a main chassis, a front panel, a cross-flow fan, a fan motor, a heat exchanger, and a discharge port. The main chassis has a backside fixed on a place to be installed. The front panel is formed on the front of the main chassis and has a spacer formed in an inside thereof. The cross-flow fan is disposed in the inside of the space and provided in plurals on the same shaft. The fan motor provides rotational power to the cross-flow fan. The heat exchanger is formed on the front of the cross-flow fan with respect to the flowing direction of air. The discharge port guides discharge of the air blown from the cross-flow fan.
Abstract:
A method of multi-stage substrate etching and a terahertz oscillator manufactured by using the method are provided. The method comprises the steps of forming a first mask pattern on any one surface of a first substrate, forming a hole by etching the first substrate using the first mask pattern as an etching mask, bonding, to the first substrate, a second substrate having the same thickness as a depth to be etched, forming a second mask pattern on the second substrate bonded, forming a hole by etching the second substrate using the second mask pattern as an etching mask, and removing an oxide layer having the etching selectivity between the first substrate and the second substrate, whereby the etched bottom is made uniformly even in a deep step, the edge curvature is minimized, and a T-shape is prevented from being formed on the etched wall face to thereby improve the etching quality. Further, the etching depth is previously controlled by lapping or polishing, the upper and lower substrates are precisely boned to each other using the alignment key, and a multi-layer processing is possibly performed thereto, so that the precision and the uniformity in structure of the oscillator or amplifier is obtained.

A method of producing a liquid crystal display includes forming a plurality of black matrices on an insulating substrate to define first, second and third pixel regions, forming a color filter layer on the black matrices and on an exposed portion of the insulating substrate on which the black matrices are not formed, forming an organic layer for forming an upper spacer on the color filter layer, and forming a first color filter pattern on a first pixel region, lower spacers on the black matrices, and upper spacers on the lower spacers by at least substantially simultaneously patterning the color filter layer and the organic layer for forming an upper spacer.
