  In a recent paper, eight semileptonic parameters were defined to specify the
most general Lorentz-invariant spin correlation functions for tau semileptonic
decays. The parameters were physically defined in terms of tau-decay
partial-width intensities for polarized final states. This paper studies how
these parameters can be simply measured at a tau/charm factory with
longitudinally polarized beams without using spin-correlation techniques.
Thereby the parameters can also be used to bound the effective-mass scales $
\Lambda $ for ``new physics" such as arising from lepton compositeness,
leptonic CP violation, leptonic T violation, tau weak magnetism, weak
electricity, and/or second-class currents.
