<P>PROBLEM TO BE SOLVED: To generate power from vibrational energy in an installed place for reducing the frequency of battery exchange or charging and reducing maintenance inspection cost, and to charge the power source. <P>SOLUTION: Vibration applied to a structure from environments and using conditions such as a bridge, an engine, a billow or the like is utilized to generate power, and the power is rectified so as to charge a d.c. power source. The power source is utilized for a cathode corrosion prevention method or an anode corrosion prevention method, and electric potential is retained between a structural metal easy to be corroded such as a reinforcing rod and a light alloy and a sacrificial electrode to prevent the corrosion of the structural metal. <P>COPYRIGHT: (C)2005,JPO&NCIPI |
