  • Patent number: 11937044
    Abstract: A sound emission control device comprises a plurality of guides. The guides each include an inlet connected to a branching portion that is configured to oppose a vibrating surface inside an acoustic device, an outlet communicated to the inlet, and a horn-shaped inner wall surrounding a space between the inlet and the outlet. The guides are configured to guide sound that is emitted from the vibrating surface and branched by the branching portion to the outlets that are configured to be communicated to sound emission holes that are provided in the acoustic device and face mutually different directions, respectively.

  • Patent number: 11937046
    Abstract: A sound diffuser includes a first annular control member, a second annular control member, and a third annular control member. The first annular control member includes a first communication hole and an annular inclined plate that surrounds the first communication hole and is inclined relative to an axial direction of the first communication hole. The second annular control member includes a second communication hole and an annular inclined plate that surrounds the second communication hole, houses the first annular control member therein, and is inclined relative to an axial direction of the second communication hole. The third annular control member has a plurality of third communication holes and surrounds the second annular control member.

  • Publication number: 20230033480
    Abstract: A data processing apparatus according to one aspect is provided with an inference unit configured to predict at least one objective variable from a plurality of explanatory variables by using a trained model, and a display data generation unit configured to generate data for displaying an inference result by the inference unit. The inference unit is configured to set a first explanatory variable selected from the plurality of explanatory variables as a variation value and set second explanatory variables other than the first explanatory variable as fixed values. The inference unit predicts, by using the trained model, the at least one objective variable when the first explanatory variable is continuously varied within a predetermined variation range. The display data generation unit generates data indicating a variation of the at least one objective variable with respect to a variation of the first explanatory variable.

  • Publication number: 20210372868
    Abstract: Provided is a stress measurement device capable of easily grasping the behavior of a stress generation site in a sample. The stress measurement device is provided with a camera for imaging light emitted by a stress luminescent material, a controller for processing an image captured by the camera, and a display for displaying the image processed by the controller. The controller detects the stress generation site according to a luminescence distribution of the stress luminescent material for each of the plurality of time-series images captured by the camera and controls the display such that each stress generation site detected for each of the plurality of images is displayed on one image in a superimposed manner in mutually different display modes.

  • Publication number: 20210356400
    Abstract: A stress luminescence measurement device according to a first aspect is provided with a load application mechanism configured to deform a sample by applying a load to the sample, a light source configured to emit excitation light to a stress luminescent material 2 arranged on a surface of the sample, a camera configured to image luminescence of the stress luminescent material, and a controller configured to control the load application mechanism, the light source, and the camera. The controller acquires a deformation state of the sample at the imaging timing by the camera and stores the acquired deformation state of the sample in association with the image captured by the camera in a memory.

  • Patent number: 8700261
    Abstract: Provided is an active damping device (X) that suppresses vibrations of an object (T) to be damped by utilizing a reaction force generated when an auxiliary mass (1) is driven by an actuator (2). The active damping device (X) includes a stiffness/damping controller (5) that multiplies the displacement and the operating speed of the actuator (2) by the stiffness gain (k1a) and the damping gain (c1a) and provides feedback of the multiplication result so that the natural frequency of a damping device machine system (X1) becomes equal to the excitation frequency (?) of the object (T) to be damped and the damping device machine system (X1) is controlled to have properties of counteracting the damping thereof. The stiffness/damping controller (5) is configured to adjust the stiffness gain (k1a) and the damping gain (c1a) according to the varying excitation frequency (?).
