Unsigned_16 already has a build-in "or" operation:

declare
   I, J : Unsigned_16 := ...;
begin
   ... I or J ...
end;

If you want to mix U16 with other types (a signed integer, say), then you'll
have to convert the type to unsigned.  You have to decide whether a straight
type conversion is appropriate, or whether Unchecked_Conversion is
necessary, e.g.

function To_Unsigned is new Unchecked_Conversion (Integer_16, Unsigned_16);

declare
   I : Unsigned_16 := ...;
   J : Integer_16 := ...;
   K : Unsigned_16 := I or To_Unsigned (J);
begin
