摘要： The invention relates to a method for the continuous casting of steel, comprising charging molten steel from a tundish into a mold through exit ports (33) of an immersion nozzle (22), introducing a magnetic field vertically to a flow of the molten steel from the exit ports (33) by the use of at least a pair of direct current magnets (23) which are arranged on the outer side of copper plates (21) on the wide side of the mold, the immersion nozzle (27) being placed between the direct current magnets (23) and the polarities of magnetism on the top side of the magnets (23) being the same, and casting the molten steel at a predetermined casting rate. One magnetic pole of the direct current magnet (23) is positioned at an upper end of copper plate (21) on the wide side of the mold and the other magnetic pole is positioned lower than the exit port (33) of the immersion nozzle (22) and on the outer side of copper plate (21) on the wide side of the mold. The immersion nozzle (22) has two exit ports (33), each of which has a downward angle of 15 to 45 DEG . The direct current magnetic field is controlled within the range of 1000 to 4000 gauss.

摘要： A distance measuring method and apparatus in which first and second pseudo random signals which are the same in pattern but slightly different in period are generated to obtain a correlation output of the first and second pseudo random signals before transmission thereof as a reference correlation output, and the first pseudo random signal is directly transmitted toward a target or alternatively a carrier wave is modulated by the first pseudo random signal and transmitted toward the target. A correlation output of the signal reflected and received from the target and the second pseudo random signal is detected and the distance to the target is measured from the time interval between the reference correlation output and the received correlation output. Alternatively, the modulated carrier wave reflected and received from the target and the second pseudo random signal are subjected to correlation processing to detect a correlative modulated carrier wave and the correlative modulated carrier wave is subjected to orthogonal detection by a reference carrier wave thereby obtaining a target detection output. Then, the distance to the target is measured from the time interval between the reference correlation output and the target detection output.
