  • Patent number: 4968530
    Abstract: The coating method includes the intercoating step for spraying the intercoating paint over a substrate after undercoating, the intercoat drying step for drying the intercoat on the substrate, the overcoating step for spraying the overcoating paint over the dried intercoat on the substrate, and the overcoat drying step for drying the overcoat. In the intercoating step, the intercoating paint is sprayed in such an amount as causing sag, that is, in an amount beyond its sagging threshold value. In the intercoat drying step, the substrate is rotated about its horizontal and longitudinal axis to dry the intercoat.

  • Patent number: 4967609
    Abstract: A flexible boot having a bellows and mount portions on both axial ends of the bellows portion at which the boot is mounted on parts of a mechanism such as an automotive constant velocity joint. The flexible boot has an anti-degradation agent make-up element made of a material which contains an anti-degradation agent and which is capable of allowing the anti-degradation agent to precipitate on the surface thereof. The anti-degradation agent make-up element is fitted on at least a portion of the outer surface of the bellows so that the anti-degradation agent precipitated on the surface of the material of the anti-degradation agent make-up element is caused to progressively immigrate into the material of the bellows thereby making-up the anti-degradation agent in the bellows.
