内容記述 | A Seismograph system for recording seismic waves by means of a triggered magnetic tape recorder was completed some years ago. Since then, earthquake observations by means of this system have been extensively made. As will be shown in the papers the equipment was originally designed and constructed utilizing vacuum tubes; hitherto, transistors were used for the purpose of economizing the expense of power supply and im- proving the portability of the equipment. For our purpose, it is necessary to have at least a three-component seismograph at one seismological station. In order to get more information on seismic waves, we used a multi-channelled FM carrier magnetic tape re- cording by frequency-division method in our system. The principal limitation of the FM carrier system derives from variations in the tape motion or the flutter which produce changes in the recorded frequency that in turn manifest in the out-put as noise. | |||||
