The history of Japanese turbine generators started with introducing the Western knowledge and technologies after Meiji Restoration, and improved mainly by referring to the Western manufacturers, especially in the initial stage. And now the Japanese technology reaches the world highest level. The Tari's research showed that an advance of generator performance has something to do with improvements of background technologies such as an ability to make greater steel ingot, and there likely should be a linkage relations among them. This paper shows the correlation graphically and the strong correlation between the unit capacity of generator and the size of turbine rotor by making a multiple-regression analysis for quantitative evaluation.
