Abstract: A type-c and USB two-in-one interface wireless radio frequency receiver, including a USB interface, a USB portion, a Type-c portion, an upper cover, a lower cover, a handle, and a connecting magnet. The USB portion is connected to the Type-c portion and placed on the lower cover. The USB interface and the type-c interface are fixed in the same storage device, but they are only physically fixed together, and the internal data is stored separately and is not mixed. When exporting data, the corresponding USB or type-c interface will be used, so that no matter which interface is used, this two-in-one receiver will meet the needs. A handle with a rotary design is further provided to protect the Type-c portion from damage. The upper side of the handle is fixed to a fixing rope via the fixing hole, so as to tie the device and facilitate to carry it around.

Abstract: Embodiments of a polyester industrial yarn dedicated to a marine hawser and a preparation method thereof, relating to the technical field of industrial yarns, are disclosed. In some examples, the preparation method includes: S1, preparing a regenerated polyester chip; S2, high-viscosity anti-ultraviolet modified polyester chip; S3, antibacterial master batch; S4, mixing the high-viscosity anti-ultraviolet modified polyester chip and the antibacterial master batch, subjecting a resulting mixture to extruding and melting to form a spinning melt, and metering, spinning, and cooling to form a tow; S5, spraying a waterproof and acid- and alkali-resistant layer onto a surface of the tow; S6, subjecting the tow to first oiling; and S7, subjecting the tow to heat-setting of two-stage drawing and one-stage relaxation, network processing, second oiling, and winding forming, to obtain the polyester industrial yarn dedicated to the marine hawser.
