We considered a mesoscopic superconductor/normal metal (S/N) structure in
which the N reservoirs are maintained at different temperatures. It is shown
that in the absence of current between the N reservoirs a voltage difference
VT arises between the superconducting and normal conductors. The voltage
VT oscillates with increasing phase difference ϕ between the
superconductors, and its magnitude does not depend on the small parameter
(T/ϵF).Comment: Resubmited, some changes to Text and Figure
