﻿374 Mr. E. Takagishi on Damping Coefficients of 



unfortunately I found there slight errors concerning the 

 damping coefficients of the circuits. 



Now, let us proceed to correct them, using the same 

 notation and abbreviations for the sake of simplicity. 

 Comparing coefficients in the . equations (5) and (6) in his 

 original paper, we obtain, instead of (7), 



-2(q + r + s)

From equations (7') ii., iv., vi., vii. we obtain the same 

 equation for co 2 as (8) and (9) in his original paper. For the 

 damping coefficients q, r, and s, however, we find the 

 following values, different from, those in (10).
