  • Display device, method of manufacturing thereof, and method of improving visibility
    Patent number: 7990033
    Abstract: A display device having a surface with light-emitting regions and non-light-emitting regions, wherein the aforementioned light-emitting regions and non-light-emitting regions are subjected to simultaneous surface treatment selected from: (1) brush treatment; (2) blast treatment; or (3) combined brush and blast treatment, whereby after the aforementioned treatment the surfaces of the light-emitting regions have a 60°-mirror-surface glossiness according to JIS Z 8741 exceeding 20%, while the surfaces of the non-light-emitting regions have a 60°-mirror-surface glossiness according to JIS Z 8741 not exceeding 20%, has good visibility of images reproduced by the display, which is especially suitable for outdoor application.
    Type: Grant

  • Method of manufacturing mixtures of polydiorganosiloxanes and finely powdered silica
    Patent number: 5721307
    Abstract: A method for the preparation of a silicone rubber composition, a liquid polydiorganosiloxane (A), finely powdered silica (B), liquid polyorganosiloxane (C) and water (D) are introduced continuously into the raw material inlet of a biaxial continuous extruding and mixing machine. In the present method the liquid polydiorganosiloxane is introduced into the raw material inlet through the outer lumen of a double lumen tube and the finely powdered silica is introduced into the raw material inlet through the inner lumen of the double lumen tube. As a result, the finely powdered silica can be introduced rapidly without being scattered to the surrounding area and superior mixing of the two substances is achieved.
