  • Publication number: 20140104154
    Abstract: When electronic papers are mounted on an electronic pad in a random sorting order, display data stored in and displayed on the papers are read along with its IDs, and stored in an electronic paper management table in association with paper IDs. The order of the display data is specified with the IDs or the order of tables of contents, and a sorting order of the papers is detected based on overlap detection sensors of the papers. Display data respectively stored according to the detected sorting order of the papers are rewritten and stored in the order of the specified IDs or the tables of contents. A PC device outputs the same information as information output by another information output apparatus by obtaining and analyzing information output by the other information output apparatus, and by detecting an output source of the information and then accessing the output source.

  • Patent number: 8669627
    Abstract: An acceleration sensor is formed using an etched layer sandwiched between first and second substrates. In this case, a structure including a movable portion which is displaceable in the thickness direction of the substrates, and a support frame are formed in the etched layer. In addition, first and second fixed electrodes are formed on the first and second substrates, respectively, at a position facing the movable portion. Further, a remaining sacrificial layer is provided on the substrate by leaving a portion of a second sacrificial layer when a first sacrificial layer is entirely etched away. Therefore, when the first sacrificial layer is etched away, corrosion of the structure and the support beams is prevented because the second sacrificial layer is preferentially corroded as compared to the structure.
