摘要： A vibration damping mount assembly having a vibration damping mount main body and a tubular bracket. The tubular bracket is made of lightweight material composed of non-ferric metal or synthetic resin, and has an inside peripheral face including an upper tapered face and a lower tapered face that gradually expand in diameter towards openings at either axial end from an axially medial section. A flanged portion of a second mounting member is axially juxtaposed against an open end of the upper tapered face, while the lower tapered face is pressed against a rubber fitting, with the lower tapered face locked in contact against an annular mating face of the rubber fitting thereby providing dislodging of the vibration damping mount main body from the tubular bracket.

摘要： A vehicle steering apparatus comprises a rack shaft, a joint provided at an end of the rack shaft, a stopper for regulating a stroke amount of the rack shaft, and a spacer. The spacer comprises an annular elastic member and an annular metal member. The elastic member comprises an inner annular section fitted on the end of the rack shaft and an outer annular section. The metal member comprises an annular section surrounding an outer periphery of the outer annular section of the elastic member. The outer annular section of the elastic member comprises a projection section projecting farther to the stopper than a first abutment section of the metal member when the stopper does not regulate the stroke amount of the rack shaft.

摘要： A stable continuous production of a propylene-based block copolymer can proceed for a long time without causing accumulation of particles having a small diameter by a process having the following steps: (1) polymerizing an &agr;-olefin containing liquid propylene as a main component in the presence of hydrogen and a stereoregular polymerization catalyst in one or more polymerization reactors to obtain a polymer slurry; (2) feeding the polymer slurry to a copolymerization reactor; and (3) copolymerizing propylene and an &agr;-olefin other than propylene substantially in a gaseous phase in the presence of the stereoregular polymerization catalyst, the polymer slurry and a deactivating compound in the copolymerization reactor to obtain a propylene-block copolymer powder. The polymer slurry, discharged from one of said one or more polymerization reactors and is classified using a classification system to obtain a) a classified polymer slurry containing a large amount of particles having a small particle diameter and b) a classified polymer slurry containing a large amount of particles having a large particle diameter. A main part of the classified polymer slurry containing a large amount of particles having a small particle diameter is recycled to a final polymerization reactor of the one or more polymerization reactors.
