Assuming σ=τ=±π/2 and m_um_d≪m_tm_b, ReΔ_<31>>0, ReΔ_<22><0 and m_t^<phy><93 GeV are suggested, where σ, τ denote two fundamental phases in the Fritzsch-type quark mass matrix and Δ_<iα> stands for U_<jβ>U_<kγ>U*_<jγ>U*_<kβ> in terms of the quark mixing matrix elements U_<ij>. Further ∣U_<21>/U_<12>, ∣U_<13>/U_<23>∣ and ImΔ_<iα> are discussed.
