  • Publication number: 20250027834
    Abstract: According to one embodiment, a structure evaluation system according to an embodiment includes a plurality of sensors, a vehicle number estimator, and an evaluator. The plurality of sensors detect elastic waves generated inside a structure. The vehicle number estimator estimates the number of vehicles passing through the structure on the basis of a plurality of elastic waves detected by each of the plurality of sensors. The evaluator evaluates a state of deterioration of the structure using vehicle information relating to the number of vehicles estimated by the vehicle number estimator.

  • Patent number: 11661015
    Abstract: A holding mechanism prevents a device at a back side of a held object from being hidden by the object. Even if a large smartphone is held, clamping with a fixed clamping part and a movable clamping part prevents the fixed part from being moved, wherein a device located back of the smartphone and at the side of the fixed clamping part cannot be hidden by the smartphone. Due to the movable clamping part being movable farther from a rotation axis than the fixed clamping part, a middle portion of the smartphone in the clamping direction substantially coincides with the rotation axis when holding a smartphone with a specified width, wherein the smartphone cannot be easily moved in a Y- and Z-direction when rotating a holding part to change orientation, and also at the back side, a device located at the side of the clamp cannot be easily hidden.

  • Patent number: 11299105
    Abstract: A holding device for holding a held object is downsized to reduce an occupied space in an installation space. The holding device in which a holding mechanism for holding the held object is supported on a device main body so as to slidably project and retract includes a lock mounted on the holding mechanism and configured to lock the holding mechanism at an arbitrary projected position, the lock part including a first rotary body pivotally supported on the holding mechanism and configured to rotate upon application of certain operation, a second rotary body that rotates by a force directly or indirectly applied from the first rotary body by the rotation of the first rotary body, and an engagement part that moves between an engaged position at which the engagement part is engaged to the device main body and a disengaged position by the rotation of the second rotary body.

  • Patent number: 10787993
    Abstract: This valve device is provided with: a body (10) that has at least one passage (11, 12) for passing a fluid and valve shaft holes (13, 14, 15); a valve shaft (20), which is passed through the valve shaft holes so as to be rotatable; and butterfly valves (30, 40), which are fixed on the valve shaft and are for opening and closing the passages (11, 12). The butterfly valves (30, 40) are disposed so as to close the passages (11, 12) on a downstream side or an upstream side of the valve shaft holes (13, 14, 15) in a flow direction of the fluid. As a result, it is possible to prevent fluid leakage and achieve effective utilization of exhaust heat in an exhaust heat recovery system.
