  • Optical element driving mechanism having movable portion for holding lens
    Patent number: 11982866
    Abstract: An optical element driving mechanism is provided and includes a fixed assembly, a movable assembly, a driving assembly and a stopping assembly. The fixed assembly has a main axis. The movable assembly is configured to connect an optical element, and the movable assembly is movable relative to the fixed assembly. The driving assembly is configured to drive the movable assembly to move relative to the fixed assembly. The stopping assembly is configured to limit the movement of the movable assembly relative to the fixed assembly within a range of motion.

  • Electroconductive polymer composites for use in secondary batteries as positive electrode active materials
    Patent number: 5863454
    Abstract: An electroconductive polymer composite for use in secondary batteries as positive electrode active materials is disclosed. It includes 10-99 weight percent of a conjugated electroconductive polymer, such as polyaniline, and 90-1 weight percent of polymeric electrolyte. The latter is composed of 10-90 weight percent of an ionic salt, such as LiClO.sub.4, and 90-10 weight percent of a polymer which can form an electrolyte material with the ionic salt. The polymer, for example, can be polyvinyl alcohol or polyalkylene oxide. A method of using the electroconductive polymer composite to prepare the positive electrode of secondary batteries is also disclosed.
