  In this report we analyse three effects which may arise in a mesoscopic
multiterminal S/N structure (two normal and two superconducting reservoirs). We
show that the Josephson critical current is a non-monotonic function of a
voltage between the normal reservoirs. The influence of the spin-polarized
electrons on the Josephson critical current was also studied. We show that if
there is a temperature difference between the normal reservoirs, a voltage
between the superconductors and normal conductors arises which oscillates as
the phase difference varies. Its magnitude is much greater than the thermoemf
in the case of the ordinary thermoelectric effect.
