  • Patent number: 11446885
    Abstract: Disclosed is a friction-reducing and anti-wear composite material for a wading kinematic pair and a method of preparing the same. The friction-reducing and anti-wear composite material is prepared from carbon fiber (CF) among inorganic fillers, polyimide (PI) and polyether ether ketone (PEEK). These three materials are wet-mixed, dried and placed in a mold followed by curing by a heat press. The cured product is cooled and demolded to obtain the CF/PI/PEEK friction-reducing and anti-wear composite material for a wading kinematic pair. Tribological properties of the PEEK material are enhanced due to synergistic effect arising from hybrid organic-inorganic filling. The friction-reducing and anti-wear composite material provided in the invention has significantly reduced friction coefficient and wear volume loss under the seawater environment.

  • Patent number: 10379338
    Abstract: A mobile terminal is provided. The mobile terminal includes a display screen on a terminal housing and a periscope optical zoom lens. The display screen and the periscope optical zoom lens are arranged in a non-overlapping manner in a thickness direction of the terminal, and the periscope optical zoom lens is located in a top area of the terminal. Additionally, the periscope optical zoom lens is configured to collect an image in an optical signal form by means of optical zoom, so that an optical-to-electrical conversion chip converts the image in an optical signal form into an image in a digital signal form and the display screen is configured to display the image in a digital signal form.
