  • Patent number: 10752543
    Abstract: A glass substrate includes at least one selected from the group consisting of Li, Na, K, Mg, Ca, Sr, Ba and Zn as a reaction factor component, and includes a surface depletion layer at a surface side of the glass substrate. A total molar concentration (mol/cm3) of the reaction factor component in the surface depletion layer is decreased relative to an inside of the glass substrate. A total depletion amount (mol/cm2) of the reaction factor component in the surface depletion layer is 1.00×10?8 or more. The glass substrate has a refractive index (nd) of 1.68 or more.

  • Patent number: 10339889
    Abstract: A liquid crystal drive device includes a common driver configured to sequentially output a scanning signal having a plurality of voltage levels to a plurality of common wirings in a time division manner, a segment driver configured to output a display signal having a plurality of voltage levels to a plurality of segment wirings, and a contrast adjustment unit configured to generate contrast adjustment periods that are inserted into all duty periods, and output, to the common driver and the segment driver, a contrast control signal to control the timing of when the contrast adjustment periods are inserted into the duty periods in synchronization with the timing of the scanning signal and the display signal. The scanning signal and the display signal are output at an identical potential when a contrast adjustment period is indicated by the output of the contrast control signal.

  • Patent number: 5830621
    Abstract: The present invention is intended to provide a photosensitive rubber plate high in strength balance and image reproducibility and a photosensitive elastomer composition used for obtaining the rubber plate. A photosensitive elastomer composition is obtained by kneading 65 parts by weight of a phosphoric acid ester group-containing random copolymer (monomers composition: 60% of butadiene, 9% of methyl methacrylate, 20% of 2-methacryloxyethyl phosphate, 10% of styrene and 1% of divinylbenzene), 35 parts by weight of a polystyrene-polybutadiene-polystyrene type block copolymer, 15 parts by weight of 1,7-heptanediol dimethacrylate, 1 part by weight of benzoin methyl ether and 0.02 part of methylhydroquinone. By interposing this photosensitive elastomer composition between two polyester films and pressurizing them with a press, a photosensitive rubber plate having a total thickness of 3 mm is obtained.
