 note = {This paper gives the drawing method of the scale attached to a. c. circuit circular diagram based on a simple and unified ideas. The method is to utilize the character of the straight line which is explained next and is treated with complex geometry, for the drawing of the scale. And the line above mentioned is such a one as passes through the two intersecting points of two circles picked out from a group of circular diagrams on a a. c. circuit., Article, 信州大学工学部紀要 13: 1-50 (1962)},
