Recent results of APW band calculations of ThNiSn, Th_3Ni_3Sb_4 and La_3Au_3Sb_4 are summarized. These compounds are proper reference materials for the study of semiconductor-like property of UNiSn, U_3Ni_3Sb_4, Ce_3Au_3Sb_4 and Ce_3Pt_3Sb_4. The valence bands consist of the Sn/Sb 5p and the Ni 3d/Au 5d states. The conduction bands are derived from the Th 6d/La 5d states and are raised by the mixing between the Th 6d/La 5d state and the Ni 3d/Au 5d state. A band gap appears between the occupied valence bands and the empty conduction bands. On the basis of these results, the origin of gap formation in UNiSn, U_3Ni_3Sb_4, Ce_3Au_3Sb_4, Ce_3Pt_3Sb_4 and isostructural uranium and cerium compounds is discussed.
