摘要： Disclosed is a lance system for inter-tube inspecting and lancing as well as barrel spraying of heat transfer tubes of a steam generator in a nuclear power plant, so that foreign substances piled up around heat transfer tubes in the steam generator are removed using high-pressure water. The lance system includes a rigid guide support rail positioned above a Blow Down Lane (BDL) at the center of the steam generator, a locomotion box including a motor drive unit for inducing a rectilinear motion of a lance body and a motor drive unit for inducing a rotational motion of the lance body centering on a horizontal axis, the lance body including a circular barrel including a motor drive unit for vertically erecting or horizontally laying down a multistage circular pole assembly, and a flat plate provided with linear passages for passing high-pressure water hoses, an optical cable and control rods therethrough, a circular drum assembly for stably connecting the high-pressure water hoses, the optical cable and the control rods, and the multistage circular pole assembly being extensible and contractible by the movement of the control rods obtained by engaging teeth of a toothed belt unit, driven by a motor and positioned in the circular barrel, with gear teeth of the control rods, and two nozzle blocks, for barrel spraying, provided with barrel spray nozzles fixedly assembled therewith, symmetrically fixed to the inner surface of the circular barrel, wherein the multistage circular pole assembly is vertically erected in the operation of inter-tube lancing and inspecting, in which the lance system approaches inner parts of the heat transfer tubes and sprays the high-pressure water thereto, and is maintained in a horizontally laid-down position in the operation of barrel spraying.

摘要： An automated lance system 1 is installed along the annulus of a nuclear power plant steam generator with a tube array of triangular pattern by means of a slidable guide support rail. The guide support rail 2, which is composed of two parallel circular rods 4 separated vertically with a distance, is tightly fixed inside the hand holes. The guide support rail extends from a hand hole at 0 degree to the other hand hole at 90 or 180 degree. The lance body 3 is slideably held on the guide rail by means of supporting circular holders 26 which are attached both on the bottom and on the upper plates of the lance body. The lance body is comprised of a nozzle block 6 with a nozzle cylinder 7 and a first drive means 9 which makes sweeping motion of the nozzle cylinder, a second drive means 12 which aligns the direction of nozzle jets from the nozzle cylinder by rotating the nozzle block in the horizontal plane, and two side support wheels 23 attached to the outer side plate of the lance body, rolling along the inner wall of the steam generator during lancing. For the transportation of the lance, two control cables 27 which extend outward through the hand holes are attached to both ends of the lance body and are driven by a drive means with a drum 28.

摘要： A liquid crystal display device with a repair structure that facilitates repair of a short circuit or an open circuit. In the device, a gate line is formed on an insulating substrate and a gate electrode is integral to the gate line. A semiconductor layer is formed on the gate electrode with having an insulating film therebetween. A data line is crossed with the gate electrode, and a source electrode is integral to the data line on the semiconductor layer and the gate electrode. A drain electrode is spaced oppositely the source electrode. A protective film has a first contact hole at the drain electrode. A pixel electrode is formed on the protective film and is connected, via the contact hole, to the drain electrode. The pixel electrode has an area overlapped partially with the data line and is spaced from the gate line by a desired length (a) at one or more corners thereof. A storage electrode extends from the pixel electrode to be overlapped partially with the gate line and is spaced from the data line by a desired width (6) at one or more corners thereof.
