A rubber composition for a tire having improved in low fuel efficiency, wet skid performance, abrasion resistance, and steering stability with favorable balance, and tire which has tread, using the same. The signal components in a each of a number of groups of signal components are weighted based on respective interference estimates to thereby adjust signal components for colored interference, which may vary significantly between different groups of signal components. , between Mobile Switching Centers in a CDMA network. The coated semiconductor chip is placed in the alignment and joining device so that when the scanned and stored alignment pattern is activated the alignment and joining device positions the coated semiconductor chip so that the first electrical interconnect structure is aligned to make electrical contact with the second electrical interconnect structure. The filtration segment consists of two sequences of at least one filter cassette, a distribution plate and at least one additional filter cassette, located between two end plates and interconnected by a common collection plate for the evacuation of the filtrate. Methods of making the push-pull fiber optic connector are also disclosed.
