内容記述 | Since 1946 the authors have developed a telerecording chronograph making use of the high-frequency carrier waves of 100-300kc through civil telephone lines, for the purpose of giving accurate time marks and other necessary signals, including vocal communications, from a central base station of local seismological network to its branch stations. As early as in 1950 they constructed a simple practical transmitter and receiver for this time-marking system (cf. Ref. 1). They introduced it into their seismological network on the occasion of swarm earthquake of Wakayama in 1953. The result was satisfactory. It carried on quite efficient observation work of high accuracy, giving to every 5 branch stations of the network the minute and second time signals to be placed on the seismograms from the standard chronometer at the central base station (Kainan) which was calibrated by the standard time signals of JJY from the Tokyo Astronomical Observatory. Nevertheless, some practical inconveniences or defects were, of course, revealed during the expedition, and the authors developed new types of transmitter and receiver in 1954. In the autumn of the same year the authors used the new line telerecording chronograph (LTC-II) together with the former instrument (LTC-I) in Wakayama with satisfactory results. | |||||
