内容記述(抄録等)lt is well known that a simple pendulum shows the ”Isochronism” 'when the pendulum bob swings through a fairly small arc such as sinθ=θ. That is, theperiod T of the swing is proportional to the square root of the pendulum's length L, but independent of the mass of the bob ;T=2π(L/g)1/2. However, when the swing executes larger size of the arc, that is, sinθ=θ, the isochronism may be destroyed and the period T' becomes slightly larger and is shown as T'=T{1+K(θ)}. As a matter of fact, however, it is not so clear what is an actual size of the arc which is fairly small as mentioned above. The present author examined of this size and showed that the angle of this small arc might not be more than about 20° on either sideof the vertical. And also in this brief report, the conditions for the decomposition of the isochronism had been discussed. lt seems rather easy to recognize the destruction of the isochronism with the precise measurement (On this point, the present author had already made an experimental and the results which will be seen in the next volume of this bulletin).
