  • Patent number: 10000037
    Abstract: The purpose of the present invention is to prevent an increase in reflectance and a decrease in transmittance, retain the intact instantaneousness and ease of stripping, improve the releasability of the adhesive, avoid the generation of distortion due to the thickness of the adhesive, and ensure the visibility, by laminating filmy members (10) each equipped with a moth-eye structure (12). This transparent laminate (1) comprises a plurality of filmy members (10) which each comprise a base (11) and, disposed on at least one surface thereof, a structure (12) made up of recesses and protrusions which have been regularly arranged at a pitch not longer than the wavelengths of visible light. At least the ends of the filmy members (10) have been superposed, with a pressure-sensitive adhesive layer (2) interposed therebetween. In the superposed filmy members (10), there is a space (14) between the opposed structures (12).

  • Patent number: 8396702
    Abstract: An analyzing apparatus includes a result-data storing unit that determines whether result data that is calculated as a result of analysis is restorable by linear interpolation. If the result data is determined to be unrestorable by the linear interpolation, the result-data storing unit stores the result data in a predetermined storage unit. Moreover, the analyzing apparatus includes a data restoring unit that reads the result data from the storage unit. The data restoring unit performs the linear interpolation using the result data acquired, thereby restoring the result data.
