Abstract: Disclosed is a bionic electric power-driven shoe, comprising a shoe sole (1), wherein a plurality of rotating wheels (2) are arranged below the shoe sole (1); an electric motor (3) is further provided at a lower part of the shoe sole (1); an output end of the electric motor (3) is connected to a transmission device in driving connection with the rotating wheels (2); and the shoe sole (1) comprises a heel part (11) and a sole part (12), the heel part (11) and the sole part (12) being in rotational connection.

Abstract: Disclosed is an anti-reverse rotation device of a power-driven shoe device, the power-driven shoe device comprising a shoe sole (1), wherein a group of front wheels (2) and a group of rear wheels (3) are arranged on a lower side surface of the shoe sole (1); and the front wheels (2) are connected to an anti-reverse rotation mechanism for preventing the front wheels (2) from rotating in reverse. The anti-reverse rotation mechanism can prevent the front wheels (2) from rotating in reverse, and as such, when the front wheels (2) are independently in contact with the ground and a certain included angle is formed between a shoe body and the ground, the situation of the front wheels (2) applying a certain pressure to the ground and the front wheels (2) rotating in reverse, such that a lifted foot moves backwards, thereby causing a person to fall down, is avoided, and walking safety is improved.

Abstract: A breathing system for an anesthesia machine is provided, which comprises an operation mode switch, a CO2 canister, a bellows, a patient inspiratory branch and a patient expiratory branch. The operation mode switch comprises a vent communicating with the patient inspiratory branch, a vent communicating with the patient expiratory branch, a vent communicating with the bellows, and a vent communicating with the CO2 canister. The CO2 canister is positioned below the operation mode switch, so as to collect the water flowing through the operation mode switch.

Abstract: The present disclosure teaches a photolithography plate and a mask correction method, and relates to the field of semiconductor technologies. In forms of the mask correction method, a patterned mask is formed on a substrate, a location of a scattering bar embedded in the substrate is determined according to the mask, and an opening is formed at the determined location so as to embed the scattering bar in the opening. A scattering bar is embedded in a substrate of a photolithography plate so as to effectively avoid the impact of the scattering bar on a mask pattern, reduce a deposition loss, improve the correction effect, and shorten a correction time.
