摘要： A tire mounting position detection system measures a first signal strength which is the strength of a radio signal received by a first receiver (R1) for each transmitter, measures a second signal strength which is the strength of the radio signal received by a second receiver (R2) for each transmitter, and calculates an strength ratio which is a ratio using the first signal strength and the second signal strength for each transmitter. The tire mounting position detection system detects a wheel position where a tire equipped with a transmitter is mounted on the basis of the first signal strength, the second signal strength and a strength ratio for each transmitter.

摘要： Without significantly impacting monomer conversion, the cis-1,4 mer content of conjugated diene mer in polymers can be increased by adding one or more Lewis bases to a catalyst composition that includes a Group 3 metal atom-containing carboxylate. This effect can be seen even at above average monomer concentrations.
