  • Vehicle torsion beam suspension and vehicle torsion beam
    Patent number: 10688843
    Abstract: A torsion beam of a vehicle torsion beam suspension has a closed cross section. A beam center portion has an inverse substantially v-shaped cross section or a substantially v-shaped cross section. Circumference increasing portions having a longer circumferential length toward the beam ends are disposed at opposite sides of the beam center portion. Each circumference increasing portion has a beam width that is a width in the fore and aft direction of a vehicle body, the beam width gradually increasing toward a beam end, and increasing at a higher rate as a position of the beam width is closer to the beam end.

  • Process for preparing shaped article
    Patent number: 3957941
    Abstract: A process for preparing a shaped article made of hydrolyzed ethylene-vinyl acetate copolymer having an improved impact resistance by conditioning the shaped article to contain water within the range of 0.2 to 3.0 % by weight to the article. The impact resistance of the shaped article can be improved without losing the advantageous characteristics of the copolymer and the improved article can be suitably employed as engineering plastics.
