  • Publication number: 20220145655
    Abstract: A sliding seismic isolation device includes a structure fixation plate having a first sliding surface and a metallic slider having a second sliding surface contacting the first sliding surface. A friction member composed of a single-layer fabric is attached to the first sliding surface, the second sliding surface, or both of the first sliding surface and the second sliding surface. One of a warp and a weft is formed of multiple plied yarns into which high-strength fibers and PTFE fibers are twisted together and the other of the warp and the weft is formed of multiple high-strength fibers in the single-layer fabric. The single-layer fabric has a twill weave and is woven such that the plied yarns of the one forming the single-layer fabric are exposed at a surface opposite from the attachment side of the friction member more than the high-strength fibers of the other forming the single-layer fabric.

  • Patent number: 7246079
    Abstract: Based on numerical values with respect to factors influencing shares of existing products and a new product evaluated by more than one people, a structured neural network calculates predictive shares of the new product predicted by the respective persons. Comprehensive evaluations on the respective products and the new product are calculated for each person, based on the numerical values with respect to the respective factors. Correlation coefficients between the comprehensive evaluations on the respective products by the respective persons and the actual shares are calculated. The predictive shares calculated by the structural neural network are layered out in accordance with the correlation coefficients for the respective person. Average values of the predictive shares and confidence intervals are calculated for the respective layers, and based on them and the calculation result obtained by the structured neural network, a share of the new product is predicted.
