20140052393 | METHOD FOR DETERMINING SPATIAL LOCATION OF CONDUCTING WIRE AND AERIAL EARTH WIRE OF POWER TRANSMISSION LINE - Disclosed is a method for determining the spatial location of a conducting wire and an aerial earth wire of a power transmission line, so as to solve the problem that the method in the prior art is not applicable to determining the spatial location of the conducting wire and the aerial earth wire of the conventional power transmission line with respect to lightning shielding failures. In the present invention, according to the physical locations of the conducting wires and aerial earth wires, the power transmission line shielding efficiency is calculated based on that the corresponding lightning shielding failure trip rate is zero when the exposure arc is zero, thus providing designing and operating units with a reliable analytical method for preventing lightning shielding failures, and meanwhile working out the shielding efficiency of the conducting wire of each phase more accurately, so as to analyze the structural relations between the aerial earth wires and conducting wires to determine the lightning protection effect of the whole power transmission line. The present invention provides a supplementary analytical method of the shielding efficiency of the existing power transmission lines. | 02-20-2014 |

20130243016 | LASER ANTIREFLECTION DEVICE AND LASER APPARATUS COMPRISING SAME - A laser anti-reflection device includes a polarizing beam splitter, a λ/4 wave plate and an absorber disposed in an outgoing light path of a laser emitting linearly polarized light with a wavelength of λ. The linearly polarized light from the laser passes through the polarizing beam splitter and the λ/4 wave plate in turn to become a circularly polarized light beam. Part of the circularly polarized light beam is then reflected by a workpiece to be processed along the original light path and passes the λ/4 wave plate to become a linearly polarized light beam with a polarization direction vertical to that of the outgoing linearly polarized light beam. The vertical polarized beam passes the polarizing beam splitter, deviates from the light path of the outgoing linearly polarized light beam and reaches the absorber. The laser anti-reflection device prevents reflected light from damaging the laser from high power lasers. | 09-19-2013 |
