  • Patent number: 9448678
    Abstract: A capacitive transparent touch sheet has excellent visibility and durability without changing the sensitivity, size, or the like of a touch panel. The capacitive transparent touch sheet comprises: a first conductive sheet including a first substrate to be adhered to the hard substrate, and a plurality of strip shaped first electrodes formed separately on a surface of the first substrate to be adhered to the hard substrate; a second conductive sheet including a second substrate disposed to oppose the first substrate, a plurality of strip shaped second electrodes formed on a surface of the second substrate opposing the first substrate and arranged to cross the first electrodes, and at least one insulation part formed continuously with the second electrodes, the at least one insulation part having a thickness the same as that of the second electrodes; and an adhesive layer that bonds the first and second conductive sheets together.

  • Publication number: 20150193046
    Abstract: A capacitive transparent touch sheet has excellent visibility and durability without changing the sensitivity, size, or the like of a touch panel. A capacitive transparent touch sheet is a capacitive transparent touch sheet that comprises: a substrate; strip shaped first electrodes comprising a transparent metal oxide and formed separately on a first surface of the substrate; strip shaped second electrodes formed on a second surface of the substrate opposite to the first surface and to cross the first electrodes; and at least one insulation part formed continuously with the second electrodes and having a thickness the same as that of the second electrodes. The second electrodes comprise conductive nanofibers conductively connected with each other, and a binder resin for holding the conductive nanofibers on the substrate; and the at least one insulation part comprises the binder resin that constitutes the second electrodes without the conductive nanofibers.

  • Patent number: 5997216
    Abstract: A neutral buoyancy auto-balancer eliminates the need for complex manipulation and operation in accordance with a change in diving depth. The auto-balancer automatically follows, rapidly and precisely, the change in diving depth by natural breathing during diving, and resolves the risk of failure of air-trapping not only in the vertical position but also in a slanted position to automatically follow a working posture of the diver. The neutral buoyancy auto-balancer comprises a weight 4 which radially outwardly extends from a shaft 14 which is rotatably supported at central holes 121, 131 of a cylinder 11 body. A nozzle 22 of an inlet duct 2 is fixed in the opposite direction to the projected weight 4. An inlet port 32 of an outlet duct 3 for both air evacuation and feed and drainage of water radially outwardly opens in the same direction as the weight 4.
