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.

Abstract: The present invention provides a method for preparing gas hydrates by reacting a plurality of guest gases with water, wherein a first guest gas has a higher water solubility than that of a second guest gas, and the pressure of the gas hydrate formation condition of the second guest gas is lower than the pressure of the gas hydrate formation condition of the first guest gas.While the traditional gas hydrate production method, wherein a single guest gas is reacted with water, is unsatisfactory in terms of cost effectiveness and productivity, the present invention provides improved production yield of gas hydrates and enables an easy production of gas hydrates at lower pressure.
