Abstract: A pneumatic tire includes a non-conductive tread surface and has an electrically conductive rubber in a wave-like or other configuration arranged in a tire circumferential direction. The tire has an electrically conductive sidewall rubber. Upper portions of the wave-like conductive rubber configuration are on the tread surface, while lower portions of the wave-like rubber configuration contact the electrically conductive sidewall rubber. As the tread surface and the electrically conductive rubber on the tread surface are worn away through use, the diametrically outermost portion of the electrically conductive sidewall rubber of the tire comes into contact with the ground and maintains an effective electrically conductive path.

Abstract: Disclosed is a film sticking device that sticks a first film substrate and a second film substrate together on a curved-surface shape. The film sticking device includes a mold having a curved attachment surface formed into a desired curved-surface shape; an attracting and holding unit capable of relatively moving on the curved attachment surface and having plural vacuum chambers on which an attracting surface for attracting and holding the second film substrate is provided; and a suctioning unit capable of separately applying suction processing to the plural vacuum chambers. The suctioning unit starts, as the attracting and holding unit moves, the suction processing of the vacuum chamber corresponding to a position opposing the second film substrate and sequentially stops, as the second film substrate is stuck to the first film substrate, the suction processing of the vacuum chamber corresponding to the stuck second film substrate.

Abstract: Methods and apparatus are provided for making a rotor blade spar from composite material wherein a multi-component mandrel is used to form the composite spar. The mandrel is made using a number of components, which are assembled to provide a structure that is sufficiently strong to maintain the spar shape during pre-cure lay up, compaction and curing of the composite material. The multiple components used to form the mandrel can be separated from each other and easily removed from the spar either before or after curing of the composite material. The mandrel components can then be re-assembled and re-used to form additional composite spars.
