Abstract: The disclosure provides a composite anode electrode material and a preparation method thereof, an anode electrode material and a lithium ion battery. The composite anode electrode material includes a defect-type transition metal oxide and a lithium titanate, wherein the lithium titanate is compounded with the defect-type transition metal oxide in the manner of coating and/or doping, the defect-type transition metal oxide is a secondary particle, and a transition metal element in the defect-type transition metal oxide is selected from any one of tungsten, yttrium and tin. The probability of a side reaction between the defect-type transition metal oxide and an electrolyte is greatly reduced and a volume expansion effect of an anode electrode of a battery in the process of deintercalating lithium ions is greatly reduced, thereby the lithium ion battery including the composite anode electrode material has a higher capacity retention rate after cycling.

Abstract: Disclosed is a folding canopy with an automatic opening and closing center small-roof structure, the folding canopy includes a plurality of canopy leg tubes and a folding canopy frame located above the canopy leg tubes. The folding canopy frame comprises a plurality of canopy struts, one end of each canopy strut is hingedly coupled to a center roof disk, a small-roof upper disk member is provided above the center roof disk, a small-roof lower disk member is provided below the center roof disk, a elevating rod is provided between the small-roof lower disk member and the small-roof upper disk member, and the small-roof lower disk member is movable vertically along with the opening and closing of the folding canopy, so that the small-roof upper disk member is movable vertically by the driving of the elevating rod.

Abstract: A folding canopy with a layered roof includes canopy leg tubes, a beam assembly connected between the canopy leg tubes, and a roof assembly for supporting a tarpaulin. The roof assembly includes a first roof unit in a middle portion of the roof assembly and a second roof unit surrounding the first roof unit. The first roof unit includes a first tarpaulin, a tarpaulin stay for supporting the first tarpaulin, and a linkage rod for linkage of the tarpaulin stay. A middle portion of the tarpaulin stay is hinged with a first strut, one end of the tarpaulin stay is hinged with an end of the linkage rod and the other end of the tarpaulin stay is a free end, and the other end of the linkage rod is hinged with a second strut.

Abstract: A folding tent with central self-lock structure comprises a plurality of tent leg tubes, a plurality of side cross units, a plurality of middle cross units and at least one central self-lock mechanism. The central self-lock mechanism is configured to be installed in cooperation with one end of the middle cross units. The central self-lock mechanism includes a lock rod assembly, a self-lock unit, an upper disc member and a lower disc assembly. When the folding tent is in an unfolded state, the self-lock unit and the lock rod assembly are locked, and a spacing between the upper disc member and the lower disc assembly is the smallest; when the folding tent is in a retracted state, the self-lock unit and the lock rod assembly are unlocked, the lock rod assembly is telescopic, and the spacing between the upper disc member and the lower disc assembly increases with the retraction.

Abstract: The present invention discloses a magnetic damping mechanism of a fishing reel, including a carrier having a magnet, a damping disc disposed on reel shaft and being rotatable together with the reel shaft, an adjustment knob partially exposed out of the side cover, a driving member engaged with the adjustment knob, and a base connected to the driving member. The base has a through hole for receiving the damping disc; a main spring, which enables the rocker arm to always have a trend to rotate away from the damping disc, is disposed on the base. When the magnetic lines are cut and the induced current is generated when the damping disc rotates together with the reel, the rocker arm is drawn close to the damping disc in the axial direction, to generate a greater damping force. That is, the faster the reel rotates, the more the rocker arm is drawn.

Abstract: Embodiments of the present invention may provide a clock and timing generation scheme for a video signal processor (e.g., a scaler), which enables fast switching between different input video standards without disturbing the output clock or timing. The scheme also may minimize the number of video frames that are dropped or repeated at the output. This may be achieved by locking the video's output timing to the input timing and also by utilizing a frame buffer to remove instantaneous discontinuities caused when an input is changed.
