  We report the angular diameters of two Mira variables (U Ari and Z Sco),
three semiregular (SR) and irregular variables (SW Vir, eta Gem and mu Gem) and
a supergiant SR variable (TV Gem) by lunar occultation observations in the
near-IR broad K-band (2.2 micron). Lunar occultations of eta Gem and mu Gem
were also observed for the first time simultaneously in both the K and L'
bands, yielding angular diameters at 2.2 and 3.8 micron. Effective temperatures
and linear radii are also derived for all the observed sources and compared
with earlier measurements. The mode of pulsation of both Mira and SR sources in
our sample is discussed.
