Gates in an old MOS chip

which I don't understand:

  1. What do the numbers mean (e.g. 19/6 and 7/35 for the C gate) ?

  2. How do "input couplers" work?

Thanks in advance, Piotr

Standard notation is W/L, each in microns. Your drawing must be old high voltage stuff.

Don't know, never seen that symbology before. Maybe tri-state ??

Don't know what that means either.
