Abstract: A system for specifying a position of underwater equipment and a position specifying method performed in the system are provided to more precisely specify a position of the underwater equipment by using a band diffusion method. A system for specifying a position of underwater equipment includes a signal transmitting device(106), a signal receiving device, and a host computer(108). The signal transmitting device is installed at the underwater equipment to transmit a signal. The signal receiving device is mounted on at least three position reference units to receive the signal transmitted from the signal transmitting device. The host computer measures a time when the signal arrives at the signal receiving device to calculate a distance between the signal transmitting device and the signal receiving device.

Abstract: A method and a system for specifying the position of PRU(position reference unit) is provided to precisely specify position information of the position reference unit under a water level. The position of an antenna is measured, and the position of a signal transceiver is specified by using distance information between the antenna and the signal transceiver and posture information of a buoy(102). The distance between the signal transceiver and a signal receiving member is measured. The specifying step and the measuring step are repeated while the buoy is moved to at least three points. The position of a PRU(104) is trigonometrically measured based on the position information and the distance information. An error of the measured PRU position is eliminated.

Abstract: A method of forming a micro-pattern is provided to reduce a processing pressure and to form a film type mold by performing a thin film transfer technique using an improved rigiflex mold. A micro-pattern material(408a) is formed on a pattern surface of a rigiflex mold(406), wherein the rigiflex mold has a predetermined young's modulus of 20 to 400 MPa. A pattern surface of the rigiflex mold is aligned at a target position of a substrate(402), where a micro-pattern will be formed. The rigiflex mold is pressurized to the substrate under predetermined pressure and temperature conditions. The micro-pattern material is selectively left on the substrate by separating the rigiflex mold therefrom.
