Japanese YHP 67 and 97?

[Jake Schwartz]

Hi,
I was scanning a Japanese brochure for the HP67/97 and noticed that the drawing/images on the first page showed the "YHP" (Yokogawa Hewlett Packard) logo on the calculator bezels. Also, in the HP67 it actually said "YOKOGAWA HEWLETT PACKARD" there:


Would anyone know whether these units ever saw the light of day with the YHP designations?

Thanks,
Jake
