Disclosed is a metal window filter assembly, of a millimeter wave band, using an NRD guide. The filter assembly comprises a filter housing including parallel conductive plates and a filter for filtering a certain frequency band of an electromagnetic wave traveling therethrough. The filter includes a plurality of polygonal metal windows and a single body type dielectric line made from a non-radiative dielectric. A plurality of polygonal inserting grooves spaced by the predetermined distance are formed respectively on both surfaces of the dielectric line making contact with the parallel conductive plates. The metal windows are inserted in the inserting grooves one to one to form multi-staged dielectric resonators cascaded as a single body. The filter has a filtering function selectively passing the certain frequency band determined by an impedance coupling relationship that the multi-staged dielectric resonators have with respect to the electromagnetic wave. The filter assembly is suitable for a commercial use due to its simple structure, a small loss and superiority in processing, assembly and productivity.

The present invention relates to a flux cored wire and the method and apparatus for manufacturing the same. The flux cored wire in accordance with the present invention can prevent the flux filled inside strip from leaking out and the moisture in the atmosphere from penetrating into the flux. The method of the present invention also does not require longer processing time. For this, the flux cored wire in accordance with the present invention is comprised of: an inner tubular body formed with flat strip by curling up the side edges of the strip into a tubular body having a seam and filed with flux inside; and an outer tubular body formed with flat strip by curling up the side edges of the strip into a tubular body having a seam and wrapping around the inner tubular body in tight contact.

A method for manufacturing a solar cell according to an exemplary embodiment includes: forming a first doping film on a substrate; patterning the first doping film so as to form a first doping film pattern and so as to expose a portion of the substrate; forming a diffusion prevention film on the first doping film pattern so as to cover the exposed portion of the substrate; etching the diffusion prevention film so as to form spacers on lateral surfaces of the first doping film pattern; forming a second doping film on the first doping film pattern so as to cover the spacer and exposed substrate; forming a first doping region on the substrate surface by diffusing an impurity from the first doping film pattern into the substrate; and forming a second doping region on the substrate surface by diffusing an impurity from the second doping film pattern into the substrate.
摘要:
An apparatus and method for controlling the position of the tongs of a crane depending on bending of a slab are disclosed. Side surface detection units are installed at both ends of the tongs of a crane for gripping the side surfaces of one or more slabs, and are configured to detect one or more gaps generated due to bending of one of the slabs. A distance detection unit is configured to detect the distance between an uppermost slab and the crane. A control unit is configured to adjust the final grip position of the tongs using information about the gaps generated due to the bending of the slab. The information about the gaps is detected by the side surface detection units and the distance detection unit.
