  • Patent number: 8529759
    Abstract: An electric deionized water production apparatus in which a direct current field is applied to a deionizing chamber packed with an ion-exchange material such that ions to be discharged are allowed to migrate in the direction identical or opposite to the direction of the water flow in the ion-exchange material, whereby ionic impurities adsorbed in the ion-exchange material are discharged from the system, the ion-exchange material being a mixture of a monolith-shaped organic porous ion-exchange material and ion-exchange resin particles. The electric deionized water production apparatus has a simple structure that can reduce material cost, process cost, and assembly cost, capable of accelerating migration of the adsorbed ionic impurities to facilitate discharge of the adsorbed ions and free from a deflected flow due to swelling or shrinkage accompanying an ion-exchanging reaction, and from poor contact with an ion-exchange membrane.

  • Patent number: 7201832
    Abstract: In the electrodeionization deionized water producing apparatus, water is passed through a deionizing chamber(s) packed with an organic porous ion exchange material having a three-dimensional network structure to remove ionic impurities in the water, thereby producing deionized water. At the same time, a DC electric field is applied to the deionizing chamber(s) to discharge ionic impurities adsorbed on the organic porous ion exchange material outside the system, wherein the DC electric field is applied so that the ions to be discharged may electrophoretically move in the direction reverse to the flow of water through the organic porous ion exchange material.

  • Patent number: 5398128
    Abstract: A board for installation in a liquid crystal panel with at least one slit at a portion thereof to be bent has a resin coating applied to a bridge portion of a conductive pattern formed over the slit. The resin coating resists external load applied during bending of the board. This board may be made by a method having the steps of punching a slit in the board corresponding to a position where the board is to be bent; forming a metal laminate on the board; forming a conductive pattern by etching the metal laminate; applying a resin coating capable of resisting an external load, which is applied during subsequent bending of the board, onto the conductive pattern across the slit; and curing the resin coating. The board is thereafter bent and installed in a liquid crystal panel.
