  • Patent number: 10427345
    Abstract: Process for continuous fabrication of highly aligned polymer films. A polymer-solvent solution is subjected to a high shear, high temperature, Couette flow to extrude a thin film having polymer chain disentanglement. The extruded thin film is frozen and the solvent is allowed to evaporate to form a dried film. The dried film is mechanically drawn using a constant force, adaptive-thickness drawing system to align polymer molecular chains through plastic deformation. A suitable polymer is ultra-high molecular weight polyethylene.

  • Patent number: 9369806
    Abstract: A moving-coil electroacoustic transducer is provided which is bar-shaped and includes a vibration system. The vibration system includes a vibration diaphragm, a bar-shaped acoustic coil, an acoustic coil support, and two plucked members. The acoustic coil sleeves the acoustic coil support and is combined with the vibration diaphragm through the acoustic coil support. The acoustic coil support is integrally formed; and includes an acoustic coil mounting portion located in the middle, dampening member mounting portions located at the two ends, and a support portion disposed between two long-axis edges of the acoustic coil mounting portion.
