  • Patent number: 10626949
    Abstract: A torque fluctuation inhibiting device includes a mass body, first and second centrifugal elements, and first and second cam mechanisms. The mass body is rotatable with a rotor and is also rotatable relatively to the rotor. Each of the first and second centrifugal elements receives a centrifugal force to be generated by rotation of the rotor and the mass body. When a relative displacement is produced between the rotor and the mass body in a rotational direction, the first cam mechanism converts the centrifugal force that acts on the first centrifugal element into a first circumferential force directed to reduce the relative displacement. When the relative displacement is produced between the rotor and the mass body in the rotational direction, the second cam mechanism converts the centrifugal force that acts on the second centrifugal element into a second circumferential force directed to reduce the relative displacement.

  • Publication number: 20190016864
    Abstract: A method for photo-hardening a silicone rubber surface, the method comprising a step (A) in which a surface of a molded silicone rubber is irradiated using, for example, a xenon excimer lamp with vacuum ultraviolet light having a wavelength of 200 nm or less at an irradiation energy in the range of 10-3,000 mJ/cm2, thereby forming an oxide layer in the irradiated portion by photooxidation and thus hardening the portion. According to the method, it is possible to harden the surface of the silicon rubber into a wear-resistant surface without causing a change in gloss and while keeping the rubbery feeling intact. It is also possible to improve the oil infiltration resistance of the rubber.
