    Abstract: One embodiment of the present invention relates to a method of manufacturing polycrystalline silicon thin-film solar cell by a method of crystallizing a large-area amorphous silicon thin film using a linear electron beam, and the technical problem to be solved is to crystallize an amorphous silicon thin film, which is formed on a low-priced substrate, by means of an electron beam so as for same to easily be of high quality by having high crystallization yield and to be processed at a low temperature. To this end, one embodiment of the present invention provides a method of manufacturing polycrystalline silicon thin-film solar cell by means of a method for crystallizing a large-area amorphous silicon thin film using a linear electron beam, the method comprising: a substrate preparation step for preparing a substrate; a type 1+ amorphous silicon layer deposition step for forming a type 1+ amorphous silicon layer on the substrate; a type 1 amorphous silicon layer deposition step for forming a type 1 amorphous silicon layer on the type 1+ amorphous silicon layer; an absorption layer formation step for forming an absorption layer by radiating a linear electron beam to the type 1 amorphous silicon layer and thus crystallizing the type 1 amorphous layer and the type 1+ amorphous silicon layer; a type 2 amorphous silicon layer deposition step for forming a type 2 amorphous silicon layer on the absorption layer; and an emitter layer formation step for forming an emitter layer by radiating a linear electron beam to the type 2 amorphous silicon layer and thus crystallizing the type 2 amorphous silicon layer, wherein the linear electron beam is radiated from above type 1 and type 2 amorphous silicon layers in a linear scanning manner in which to reciprocate in a predetermined area.

    Abstract: The present invention addresses the technical problem of providing an actuator which is provided to prevent leakage through a rod in a hydraulic or pneumatic cylinder-type actuator, and in which an existing sealing member may be used, and in particular, a cable (wire) may be used as a rod for solving the problem regardless of surface roughness thereof. An actuator for solving the above-mentioned problem in accordance with the present invention includes: a cylinder having an inner portion filled with a fluid and a front cover for closing a front end portion thereof; a piston displaced inside the cylinder by the fluid; a sealing member having one end portion fixed to the piston and the other end portion fixed to the front cover; and an operation member inserted in the sealing member and having one end portion fixed to the piston and the other end portion extending out of the front cover. In the present invention, due to the above-mentioned configuration, the sealing of a fluid (f) is already achieved by the sealing member, and thus, the operation member serves a moving function if only slipping relative to the sealing member in the sealing member. Accordingly, a rod or a cable does not need to move while being in close contact with the sealing member. Therefore, as in conventional arts, the present invention has merits in that a remarkable improvement is achieved in terms of wear of the sealing member, and it is not necessary to smoothly and precisely process the rod and to smoothly and hardly coat the cable.
