  We have performed a temperature-dependent angle-integrated photoemission
study of lightly-doped to heavily-overdoped La$_{2-x}$Sr$_{x}$CuO$_4$ and
oxygen-doped La$_2$CuO$_{4.10}$. We found that both the magnitude $\Delta$* of
the (small) pseudogap and the temperature \textit{T}* at which the pseudogap is
opened increases with decreasing hole concentration, consistent with previous
studies. On the other hand, the superconducting gap $\Delta_{sc}$ was found to
remain small for decreasing hole concentration. The results can be explained if
the superconducting gap opens only on the Fermi arc around the nodal
(0,0)-($\pi,\pi$) direction while the pseudogap opens around $\sim$($\pi$, 0).
