  • Publication number: 20230366729
    Abstract: Provided is a trained artificial intelligence for detecting non-stationarity of an object, which accurately functions even in the presence of an environmental sound. Stationary vibration feature data generated from stationary vibration data that is data about stationary vibration including vibration generated in a stationary state from an object for which detection of non-stationarity is performed based on sound, the stationary vibration feature data being data about a feature of stationary vibration identified by the stationary vibration data, is input to an autoencoder to cause the autoencoder to output estimated stationary vibration feature data. A loss function between the stationary vibration feature data and the estimated stationary vibration feature data is generated, and the autoencoder is trained to minimize a difference therebetween. By repeating the above-mentioned processing, the trained autoencoder is obtained from the autoencoder.

  • Publication number: 20230146768
    Abstract: A high-torque threaded connection with male and female threadforms constituted by wedge threads is provided with high shear resistance and high torque resistance. The radius of curvature r1 of the base of the load flank of the first thread 111, located at the end of the male threadform 11 associated with the tip, is not lower than the thread height Th×0.14, and more preferably not lower than Th×0.16, to improve the shear resistance of the first thread 111. Further, the thread pitch may be reduced to increase the number of threads to increase the area of contact for load flanks, or only the radius of curvature of the base of the load flank of the first thread located at the end of the male threadform associated with the tip may be increased and smaller radii of curvature may be provided for the other portions to increase the area of contact for load flanks, thereby maintaining high torque resistance.
