<p>PROBLEM TO BE SOLVED: To make it possible for an airplane or the like to recognize a transmission line, by fitting a magnetic power tap provided with a signal generator onto a transmission line, and generating flash with power obtained from magnetic flux generated by the transmission line. SOLUTION: A power tap 30 involves a slender conductive loop or coil 32, and is disposed with its inside adjacent to a transmission line 14. The power tap 30 involves a magnetic core 40 disposed at part of the outside of the coil 32, and the magnetic core 40 functions as a magnetic flux coupler between the coil 32 and a coil assembly 42 to form a transformer. A magnetic amplifier 50 disposed passing by the coil 32 forms part of the power tap 30 to amplify the magnetic flux generated at the transmission line 14. The coil assembly 42 has two separated coils, and a winding is formed so that two voltages necessary to supply power to a flash device 20 may be generated, and a high voltage paired wire 44 and a low voltage paired wire 46 extend from the coil assembly 42 to the flash device 20.</p> |
