General idea of this equipment followed mainly the former one reported in previous papers. The induced voltage upon the receiving aerial is amplified by a shunt peaking circiut, and the cathode-ray tube is employed to draw the waveforms of atmospherics, and records are made upon films. The time axis in cathode-ray tube is supplied by a condenser and resistance chraging process whose time sweep is 1 ms,6 ms,12 ms,and 16 ms. This apparatus is designed to be devided into five parts for the benefit of transportation.}, pages = {43--47}, title = {携帶用空電波形測定機}, volume = {3}, year = {1953} }
