  If the minimal standard model of particle interactions is extended to include
a scalar triplet with lepton number $L=-2$ and a scalar doublet with $L=-1$,
neutrino masses $m_\nu \sim \mu_{12}^4 v^2/M^5 \sim 10^{-2}$ eV is possible,
where $v \sim 10^2$ GeV is the electroweak symmetry breaking scale, $M \sim 1$
TeV is the typical mass of the new scalars, and $\mu_{12} \sim 1$ GeV is a soft
lepton-number-violating parameter.
