摘要： Provided is a process for producing a modified polymer, characterized by carrying out primary modification in which a hydrocarbyloxysilane compound is reacted with the active site of a polymer having an active site of an organic metal type in a molecule and then carrying out secondary modification in which the hydrocarbyloxysilane compound is further reacted therewith. This makes it possible to provide a modified polymer which enhances interactions with silica and carbon black when used for both of silica-blended and carbon black-blended rubber compositions and which elevates the fracture characteristic, the abrasion resistance and the low heat buildup property at the same time and can exhibit a good workability.

摘要： An AC motor controlling apparatus which can exactly control the torque of an AC motor throughout a motor rotating speed range from low to high. A control mode selecting circuit 13 actuates a switching circuit 19 for allowing an exciting circuit 12 to receive a PWM signal S11 from a current feedback circuit 11 when the rotating speed Nm of the motor 1 is in a higher range, and a PWM signal from an AND gate 14 when it is in a lower range. A power feedback circuit 10 performs a feedback control for matching the power supplied to an inverter circuit 6 to a target power. The current feedback circuit 11 performs a feedback control for matching the phase currents to a target currents.
