  • Honeycomb core, honeycomb sandwich structure, and honeycomb core manufacturing method
    Patent number: 10507607
    Abstract: A honeycomb core includes carbon fiber having four or more different fiber directions, and when a ribbon direction is set as an X axis direction, a cell width direction is set as a Y axis direction, and a direction that is orthogonal to the ribbon direction and the cell width direction is set as a Z axis direction. A condition in which angles formed by the X axis direction and the respective fiber directions of the carbon fiber are set at ?45 degrees, 0 degrees, 45 degrees, and 90 degrees is set as a reference condition. The respective fiber directions are rotated from the reference condition by a fixed rotation angle so that none of the fiber directions are parallel to the X axis direction.

  • Cylinder lock device for use in structure
    Patent number: 5147018
    Abstract: A hydraulically-operated piston device installed between the frame of a structure and a vibration-resisting element provided separately from the frame varies the rigidity of the frame by changing the condition of connection between the frame and the vibration-resisting element. A valve controls the operation of the piston device and can be adjusted to change the coefficient of damping of the piston device. To obtain maximum rigidity of the frame, the piston is hydraulically locked in place. For maximum flexiblity of the frame, the piston can be hydraulically released from a locked position to move freely. Hydraulic resistance to movement of the piston can be graduated by metering the flow of oil into and out of the piston device. The coefficient of damping is a function of the metered flow of hydraulic fluid in the piston device.
