(I have no idea, but I'm trying to get Mike Cash interested).
There are zero references to Takumars in those two pages.
They're not really technical reports. They're a couple pages of lens reviews from the film camera days. The first page consists mostly of info about the construction of the lens caps. Real yawner.
Fortunately for me, I am an American and the OP specified a Japanese person, so I am excused from translating them.
