Patents by Inventor Xubo YU

Xubo YU has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 11739775
    Abstract: The present disclosure relates to an expanding and radiative flow mechanism. The mechanism has a bottom surface. The bottom surface is provided with a fluid supply port. The bottom surface of the mechanism and a surface of a to-be-adsorbed object form a gap during use. A fluid flows out from the fluid supply port, enters the gap and flows out along the gap. The gap is an expanding gap and meets the following: a radial length exists with the fluid supply port as an initial point of the flow, and a height of the gap continuously increases in an outward radial direction within this length. With improvements to a parallel radiative flow mechanism, the mechanism of the present disclosure can effectively increase an absorption force of a radiative flow, which is conducive to subsequent applications thereof.

  • Patent number: 11685059
    Abstract: The present invention relates to a turntable mechanism, including a flat plate and a rotating device for driving the flat plate to rotate, where the flat plate rotates to generate a negative pressure between a lower surface of the flat plate and a surface of an adsorbed object, the flat plate and the adsorbed object adhere together by an adsorption force generated by the negative pressure, and in this case, a gap is kept between the lower surface of the flat plate and the surface of the adsorbed object. In the present invention, a continuous, consistent, and stable fluid film is formed between the turntable and the adsorbed object, and a secondary flow is not easily generated, thereby ensuring that the adsorption force between the rotating flat plate and the adsorbed object is more stable.
