 note = {In this paper, the author treats profile shifted involute internal gears having no difference in number of teeth between internal gear and pinion and intermeshing with an appropriate center distance and with a contact ratio of greater than 1. The synthetic diagrams available for the design and production of the profile shifted involute internal gears mentioned above are prepared. The author shows a numerical example with a view to facilitating the practical utilization of these diagrams, and the profile shifted involute internal gearsets in which the difference between the number of teeth in the internal gear and in the spur pinion is equal to zero are made by providing adequate profile shifting to the internal gear and the pinion of ordinary involute tooth profile., Article, 信州大学工学部紀要 27: 157-170 (1969)},
