Abstract: The present invention relates to fine-tuning a time delay of a relay device that distributes and relays a signal from a femto base station to several antennas by using an unshielded twisted pair cable (UTP). That is, by measuring a UTP time delay between a signal distribution device, which is a component of a UTP femto distribution and relay device, and a plurality of remote signal transmission and reception devices, respectively, a cable time delay between devices is corrected so that the plurality of remote signal transmission and reception devices may relay femtocell signals at the same time.

Abstract: A hydrate production apparatus according to the present invention comprises: a main body unit having a reaction space in which a hydrate is produced therein; an inlet pipe unit connected to one side of the main body unit so as to introduce, into the reaction space, a host material and a guest material for producing the hydrate; an outlet pipe unit connected to the other side of the main body unit so as to discharge the hydrate produced in the reaction space to the outside; and a pulverizing device unit provided inside the reaction space so as to increase a reaction area for producing the hydrate by pulverizing, into fine-sized particles, an object to be pulverized, which is at least one of the introduced host material and guest material.

Abstract: A control method for a wall-mounted drum washing machine, which removes foams remaining in a detergent box and a conditioner box at a final stage of a spin-drying process of the wall-mounted drum washing machine, thereby maintaining the detergent box and the conditioner box in a clean state.

Abstract: A wall-mounted drum type washing machine includes a rear panel forming a rear surface of a cabinet, comprising a water supply device installed to supply wash water and a driving unit to provide power for a washing operation, mounted on a wall surface; a tub in the cabinet to contain wash water, integrated with the rear panel, and having a rotatable drum therein; a box unit connected to a cover unit having a door thereon, forming an outer wall of the cabinet, and coupled to the rear panel and surrounding the tub; a water supply device supplying wash water into the tub through a top surface of the cabinet; and a drain device discharging wash water from the tub to the bottom of the box unit.

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.
