  • Patent number: 8349154
    Abstract: The invention relates to modified electrodes for ER fluids prepared by adding a rough, wear-resisting, and low conductive modified layer on the surface of metallic electrodes. The material for the modified layer can be at least one from diamond, alumina, titanium dioxide, carborundum, titanium nitride, nylon, polytetrafluoroethylene, adhesive, and adhesive film. Through the addition of the modified layer, the adhesion of the ER fluid to electrodes is increased so that the shear stress measured near the plates is close to the intrinsic value, which makes the ER fluid applicable, while reducing the leakage current and increasing the breakdown voltage of the ER fluid equipment.

  • Patent number: 8350164
    Abstract: A weighing device for detecting the weight of capsules quickly including at least a hopper, an upper passageway including a discharge gate at the lower part thereof, a pushing structure, a transport wheel including a storage chamber, a discharging structure, a weighting platform, and a lower passageway. When the storage chamber of the transport wheel rotates to cooperate with the discharge gate, a capsule is pushed into the storage chamber by the pushing structure. When the storage chamber rotates to the lowest point of the transport wheel, the capsule in the storage chamber is pushed by the discharging structure and thus falls into the weighing platform disposed below the storage chamber. The weighting platform weighs the capsule and evaluates whether the capsule is up to standard. The device has high weighing efficiency.
