 note = {The observations of atmospherics were made in September 1952 and in September 1953. The wave forms were recorded and the fixing of sources was conducted by triangulation at Toyokawa, Akita and Kumamoto. Waveforms of the regular peaked type at night were analysed on the reflection theory, and the reflection height of the ionosphere and the distance of the source were calculated. Several waveforms from the same sources received at Toyokawa and Akita were discussed. Some examples were shown, indicating that the quasi-period of the second half cycle of the oscillatory component increases with distance, and its rough explanation was given.},
