  • Homogeneous electrorheological fluid
    Patent number: 5891356
    Abstract: A homogeneous electrorheological fluid is disclosed, which mainly comprises a liquid crystal compound in which a plurality of liquid crystal groups are bonded to a molecular chain either directly or via a spacer, or comprises a lyotropic liquid crystal comprising a solute and a solvent. The electrorheological fluid exhibits higher electrorheological effects as well as high response rate and low power driving properties while being free from sedimentation or flocculation.
    Type: Grant
    Filed: December 29, 1995
    Date of Patent: April 6, 1999
    Assignee: Asahi Kasei Kogyo Kabushiki Kaisha
    Inventors: Akio Inoue, Syunji Maniwa
