  • Patent number: 9229913
    Abstract: The present invention relates to a font processing technique for maintaining e-document layout. More particularly, the present invention relates to a font processing technique for a user terminal (e.g., smart phone, smart pad, digital set-top box) displaying or printing an e-document (e.g., word file, presentation file) to approximately maintain original layout of the e-document even though lacking of original font of the e-document. According to the present invention, when a user terminal displays or prints an e-document, the original layout of the e-document is maintained even though the user terminal fails to install original fonts. Therefore, the meaning of the e-document is exactly shown as intended by the author. Further, the visibility and legibility of the e-document is highly enhanced.

  • Patent number: 6811704
    Abstract: The present disclosure relates to a method for removing anions such as nitrate ion, sulfate ion, chloride ion, and phosphate ion existing in underground water, surface water or waste water. The method involves adding alumina cement and a calcium compound to the water containing the anion followed by applying an electric field thereto, thereby forming a chemical precipitate which is an insoluble complex salt. The disclosure also relates to a continuous process for removing the anion by continuously performing the above method for removing anions.
