    摘要： This invention relates to a rubber composition being excellent in the low heat buildup and fracture properties (resistance to crack growth). and more particularly to a rubber composition, characterized by compounding 10-100 parts by mass of an inorganic filler and/or carbon black based on 100 parts by mass of a rubber component including not less than 10 mass % of a modified conjugated diene-based polymer having a cis-1,4 bond content of not less than 90% and a vinyl bond content of not more than 1.2% and a primary amino group. In this case, the modified conjugated diene-based polymer is obtained by (1) reacting the predetermined conjugated diene-based polymer having an active terminal with a compound having two or more predetermined functional groups and (2) further reacting the resulting product with a compound having a primary amino group.

    摘要： A simple, low cost drive circuit secures a sufficient number of subfields in a high resolution panel. The plasma display panel drive circuit groups plural sustain electrodes into first and second sustain electrode groups, and applies sustain pulses in the sustain period. The first and second sustain pulse generating circuits generate and apply sustain pulses to first and second electrode paths. First and second specific voltage application circuits apply a first specific voltage to the first and second electrode paths. The voltage selection circuit selects one of a plurality of voltages including at least a second specific voltage and a third specific voltage, and generates a selected voltage. The first and second sustain pulse generating circuits generate the sustain pulses based on the second specific voltage when the selected voltage is the second specific voltage, and when the selected voltage is the third specific voltage, apply the third specific voltage to the first and second electrode paths.
