The improved Kelson-Garvey (ImKG) mass relations are proposed from the differences of mirror nuclei. masses 31 measured proton-rich nuclei with $7\ensuremath{\le}A\ensuremath{\le}41$ and $\ensuremath{-}5\ensuremath{\le}(N\ensuremath{-}Z)\ensuremath{\le}\ensuremath{-}3$ can be remarkably well reproduced by using relations, a root-mean-square deviation 0.398 MeV, which is much smaller than results (0.502 MeV) isobar-mirror (0.647 MeV). This because many more participating involved in ImKG for predicting unknown 144 $6\ensuremath{\le}A\ensuremath{\le}74$ predicted relations. one- two-proton separation energies these diproton emission investigated simultaneously.
