Abstract: A tenter apparatus for clipping a film includes a frame including a supporting surface supporting the film, and a clip arm which is installed to the frame and rotatable relative to the frame, clips the film along with the supporting surface of the frame and includes a plurality of first contact protrusions which is disposed at a bottom surface of the clip arm and contacts the film.

Abstract: Disclosed are a drain device having a drain filter, which causes foreign substances contained in washing water to be effectively filtered out by a filter chamber to prevent the foreign substances from flowing into a pump chamber, and allows the washing water to smoothly flow in the filter chamber to use the drain filter for a long time, and a washing machine having the same. The washing machine includes a housing provided with a washing chamber; and a drain device including a filter chamber provided with a filter member installed therein filtering out foreign substances from washing water in the washing chamber, and a pump chamber connected to the filter chamber to forcibly discharge the washing water. The filter member has a sectional area gradually increased toward the pump chamber and is provided with an end terminal separated from an inlet of the pump chamber by a designated distance.

Abstract: A solar cell manufacturing method includes forming a first electrode on a substrate, forming a mixed metal layer on the first electrode, forming a light absorbing layer by injecting hydrogen selenide on the entire surface of the mixed metal layer using a gas injection device, and forming a second electrode on the light absorbing layer. Further, the gas injection device includes a gas pipeline, an inner gas pipe positioned in the gas pipeline and having an opening, and a plurality of injection nozzles disposed below the gas pipeline.
