Query: A function from Stern's diatomic sequence, and its properties   We define a function by refining Stern's diatomic sequence. We name it the
{\it assembly function}. It is strictly increasing continuous. The first and
the second main theorems are on an action to the function. The third theorem is
on differentiability of the function at rational points.
