[sdiy] 1/x circuit ?

[JH.]

This probably falls into the log ratio category, but as it's so extremely 
simple (one CA3046 plus one opamp), I'll point to it again nvertheless:

(Not my idea - taken from the original Tau circuit - the part around U5A)

I'm looking for a 1/x circuit. I know about the
two transistor and opamp "log-ratio converter" that would work...
and of course any multiplier could be used as a divider.

Any other techniques, preferably simple ?
