The phase separation induced by the nematic-isotropic transition in the mixture of nematogen and spherical molecules in investigated, by the use of a simplified version of the model of Humphries, James and Luckhurst, which includes the effect of the isotropic part of the intermolecular potential. The diffusive instabilities of the isotropic and nematic phases are also investigated. It is shown that the coexistence region and the region of the diffusive instability become large and the triple point appears, as the isotropic part of the intermolecular potential becomes effective for the phase separation, while the isotropic part does not play an essential role at high temperatures and low concentration of spherical molecules. The relationship with the phase separation of the magnetic alloys and the ^4He-^3He mixtures is also discussed.
