Abstract: A capital letter means a bounded linear operator on a complex Hilbert space $ H$. By a nice application of the Furuta inequality, we give two kinds of determinant type generalizations (Theorems 1 and 2 in $ \S1$) of the famous and well-known Heinz-Kato theorem containing the terms $ T,\;\vert T\vert$, and $ \vert{T^{\ast}}\vert$.
