Main Parameters of the Linac-Ring Type Phi, Charm and Tau Factories
  Parameters for linac-ring type e^{-}e^{+} colliders with sqrt(s)=1020 MeV (phi factory), 3770 MeV (charm factory) and 4.2 GeV (tau factory) are discussed. It is shown that luminosities of the order of 10^{34} cm^{-2}s^{-1} can be achieved.
