  • Publication number: 20200003247
    Abstract: The present invention discloses a blind bolt fastening device, and belongs to the technical field of bolts. The blind bolt fastening device includes Z-shaped gaskets, a fixed plate, elastic hinges, a screw cap, a nut, an integrated gasket and the like. The top end of the screw cap is connected to the fixed plate in a spot welding manner. A plurality of elastic hinges is uniformly mounted on the fixed plate. One end of each elastic hinge is rotatably fixed on the fixed plate. Connection points of the elastic hinges and the fixed plate do not exceed the outer edge of the fixed plate. The other end of each elastic hinge is connected to one Z-shaped gasket in a spot welding manner. In an initial state, the plurality of Z-shaped gaskets are uniformly distributed and fitted onto the outer wall of the screw cap along a circumferential direction.

  • Patent number: 10355052
    Abstract: The present disclosure relates to an OLED display device, including OLED units and a pixel spacer layer having a plurality of opening portions, which are disposed on a substrate. Each OLED unit includes an anode, a light-emitting functional layer and a cathode which are disposed sequentially in a direction away from the substrate. The light-emitting functional layer is disposed in the opening portions. The pixel spacer layer is provided with a via hole. The display device further includes: an auxiliary electrode disposed below the pixel spacer layer, corresponding to a display area, spaced apart from the anode, and connected to the cathode through the via hole in the pixel spacer layer; and a print circuit board disposed at a side of the substrate away from the pixel spacer layer, configured to transmit a signal of the cathode to the auxiliary electrode through an conductive lead.

  • Patent number: 9469639
    Abstract: The present invention relates to naphthylurea derivatives. Such substances can significantly inhibit VEGFR2 and PDGFR-? receptor tyrosine kinase phosphorylation at nanomolar concentration levels. It is a novel type of tyrosine kinase inhibitors which can be used in the treatment of tyrosine kinase-mediated diseases or symptoms such as malignancies and ocular diseases accompanied with pathologic neovascularization.

  • Patent number: 7557007
    Abstract: The method for manufacturing a semiconductor device according to the invention includes forming a thick silicon oxide film uniformly in a trench. Argon ions or the like implanted obliquely into the trench to form an ion implanted damaged region selectively in the portion of the silicon oxide film on the trench sidewall utilizing the shadowing effects of the oblique ion implantation. The silicon oxide film is wet etched to selectively remove the silicon oxide film in the ion implanted damaged region utilizing the etching rate difference, wherein the etching rate is faster in the damaged region than in the undamaged region. As a result, a thick residual oxide film is formed on the bottom and the lower sidewall portion of the trenchwithout causing any bird's beak.
