The present invention 10 discloses a pump 24 system that can be added to an existing water cooler 16 or be an integral system. An output control circuit of an energization pattern controller supplies a combined energization of pulse depolarized type energization and at least one of direct current type energization and pulse energization between an anode-side device and a cathode-side device of iontophoresis. The measuring members can be incorporated into a stability monitoring device comprising a computer-assisted evaluation electronics system. A second controller might be located in a seismic source vehicle. The peripheral portion is thinner than the central portion. The device has an organic electroluminescent light recovery layer consisting of dielectric material and nanoscale metal particles or organic material and nanoscale metal particles.
