  • Patent number: 10799941
    Abstract: [Problem] To provide a method and device that automatically detects misalignment during flask mating in an automatic flask mating device for molding flasks for casting. [Solution] In an automatic flask mating device, an external force applied to a cope with a cope molding flask M1 during flask mating is detected by means of a physical quantity detection sensor 60, quantified by a computation/storage/determination processing device 61, and then compared with a numerical value at a normal time for determination to thereby determine whether the flask mating has normally completed and detect flask mating misalignment. A force sensor is preferably used as the physical quantity detection sensor.

  • Patent number: 10587819
    Abstract: A video image processing device uses a plurality of video data captured by a plurality of cameras to generate a wide range video data of the entire celestial sphere having a 360-degree range around an area where the plurality of cameras is installed and to transmit the generated wide range video data of the entire celestial sphere to a video display device. The video display device detects a direction of the video display device as a direction of a sight line of the user, receives the transmitted wide range video data of the entire celestial sphere, segments a predetermined area of video data including a detection result of a sensor from the wide range video data of the entire celestial sphere, adjusts a luminosity of the extracted predetermined area of video data to fall in a certain range of luminosity, and displays the adjusted predetermined area of video data.

  • Publication number: 20190195732
    Abstract: A wear detection method and system for a linear actuator such as a pneumatic cylinder, a hydraulic cylinder, an electric cylinder or the like. A physical amount detection sensor 9 is mounted on a linear actuator in which a push-pull member connected to a rod 2 pushes and pulls a pressure-receiving object while applying a lateral load in a direction different from the linear movement direction. An external force that is generated between a tube and the mounting member when the pressure-receiving object is pushed and pulled is detected by the physical amount detection sensor 9 and compared with standard external force data, which was detected in a state without abnormalities and stored in a computation/storage/determination processing device 10, to computationally determine whether the linear actuator is in a normal state or an abnormal state.
