A multi-touch sensing display apparatus is provided. Liquids or other fluids to be purified enter the purification device and, under the influence of an electric field, are treated to produce an ion-depleted liquid. After completion of the capturing, the chapter formation-commanding portion transfers the chapter table stored in the memory to a storage portion. A first electrode including a first member extends into the chamber. When a wave having a given force traveling from the body of water towards the shoreline encounters the device, the force of the wave is reduced by causing the water to travel over the device and through the spaces between adjacent pipes before reaching the shoreline.
