Abstract: PURPOSE: A method for reproducing a stereophonic sound is provided to offer the effect of 3-dimensional sound image fixing to a listener by correcting a standard head transfer function according to a size of the listener's head. CONSTITUTION: An azimuth angle and an altitude angle based on real left or right ear are calculated from a standard head related transfer function database(11) measured by using a standard head sized dummy head(12). An index of the standard head related transfer function database(11) is corrected on the basis of the azimuth angle and the altitude angle(13). A position in a 3-dimensional space is inputted. An azimuth angle and an altitude angle are calculated on the basis of left or right ear of a listener from the position inputted(15). The azimuth angle and the altitude angle calculated on the basis of left or right ear of the listener are indexed. A head related transfer function corrected(16,17) is obtained from the standard head related transfer function database(11) corrected. An input mono signal is convoluted with the head related transfer function obtained(18,19). After that, an inverse proportion factor is multiplied according to the distance. Therefore, a stereophonic sound is reproduced.

Abstract: PURPOSE: A safety valve is provided to remove cooling water or actuating fluid remaining inside a pipe in case of equipment stop for preventing breakage from cold and to remove residues. CONSTITUTION: In a rear end of an electronic valve(12), a one-way valve(13) is installed and an actuating fluid running along a T-shaped valve(5) is not allowed toward the electronic valve while only high pressure gas that has passed through the electronic valve is allowed to pass through the one-way valve. When power is normally supplied, a normal cross typed electronic valve(11) is open and the normal open typed electronic valve is closed causing the actuating fluid introduced in an actuating fluid inlet port(6) to be normally let in a pipe(7) for normal action. In case of work finished or emergency, power supply is stopped then the normal cross typed electronic valve(11) is intercepted to stop introduction of the actuating fluid. Instead, the normal open typed electronic valve is open for high pressure gas to be introduced into the pipe. Thereby, the actuating fluid remaining in the pipe is completely removed inside the pipe and danger of breakage or a problem of residues disappears.
