• A possible unified model for elementary particles is developed by generalizing the viewpoint of Sakata-Nagoya model. Instead of the Sakata triplet (p, n and Λ), we work with the quartet of new baryons x_0 and X (x_1,x_2 and x_3) of spin 1/2, of which x_0 belongs to U(1) whereas the other three to U(3). Strong interactions are subjected to a "broken U(1)×U(3)" symmetry. Baryon octet (N, Σ, Λ and Ξ) and meson octets (K, π,η,K^^-; etc.) are interpreted, respectively, as the three (xx^^-x_0)-or two (xx^^-)-body composite systems both belonging to 8-dimensional representations of SU(3). One of the crucial test of the model is the prediction of triplet mesons (xx^^-_0), the iso-doublet of which can be identified with k-mesons. The baryon quartet, x_0 and X, corresponds to four leptons in the sense of "modified" baryon-lepton symmetry. This enables us to explain Cabibbo's phenomenological weak interaction as a consequence of the present scheme.
