  • Publication number: 20190257398
    Abstract: Provided is a vibration damping device including guide surfaces that are concave surfaces formed in a support member so as to curve toward the outer periphery of the support member; mass bodies that, as the support member rotates, roll on the guide surfaces while being pressed against the guide surfaces by a centrifugal force; and inertia rings that are rotatably coupled to the mass bodies and swing about the center of rotation of the support member. When the vibration damping device is in equilibrium, the center of gravity of each mass body is located radially outward of the joint position between the mass body and the inertia rings. As the support member rotates, the inertia rings swing relative to the support member about the center of rotation of the support member, and the mass bodies roll on the guide surfaces.

  • Publication number: 20190086649
    Abstract: An image capture system including two imaging systems of the same structure each having a wide-angle lens, which includes a front group, a reflection surface, and a rear group arranged in order from an object side, has a field angle larger than 180 degrees, and bends an optical axis of the front group toward the rear group by the reflection surface, and an imaging sensor, obtains an image in a solid angle of 4? radian by combining images imaged by the imaging systems. Each of the two wide-angle lenses includes the reflection surface between the front group and the rear group, the reflection surfaces are made to be common to the two imaging systems. This reduces an interval between lenses nearest to the object side in the front groups of the two wide-angle lenses, thereby reducing a distance between maximum field angles of the two wide-angle lenses.
