  • Patent number: 11926216
    Abstract: A vibration damping device including a vibration-damping device main unit inserted into a mounting space of a bracket from a lateral side and securely supported by the bracket. The bracket includes engaging pieces on respective opposed inside faces of the mounting space, and engaging action of the engaging pieces with respect to respective detent engaging faces formed on a fixture member of the vibration-damping device main unit prevents the vibration-damping device main unit from becoming dislodged from the mounting space of the bracket. Opposed walls of the mounting space are each penetrated by an aperture window, and inspection flat surfaces are separately provided to an outside surface of each engaging piece visible from an outside through the aperture window and a corresponding external side surface of the bracket that is off the aperture window. The inspection flat surfaces are parallel to each other.

  • Publication number: 20240069124
    Abstract: An object of the present invention is to provide a magneto-optical material capable of exhibiting the Faraday effect even though no magnetic field is applied. The magneto-optical material of the present invention has a nanogranular structure in which magnetic nanoparticles are dispersed in a fluoride matrix, and can exhibit Faraday properties without requiring the application of a magnetic field because the magnetic nanoparticles are configured by a magnetic material that has residual magnetization and consists of any of a Fe—Pt alloy, a Co—Pt alloy, a Fe—Co—Ni—Al alloy, a Co ferrite, or a Ba ferrite.

  • Patent number: 11568684
    Abstract: The invention provides a control unit and a control system for a vehicle capable of reducing a workload of deleting a record of information of an unintended event detected by a certain control unit by preventing the other control unit from recording the information of the event. Control units (50a to 50d) that are mounted on the vehicle and connected in a mutually communicable manner each include an event processing section (55). The event processing section (55) executes one or both of processing to switch whether to notify a recording request of the information of the event and processing to switch necessity/unnecessity of recording of the information of the event.
