This article elaborated the "inductive jet" principle of air current and the application in draining water accumulated in the factory,explained the feasibility and practicability of using vacuum absorption as the power supply to drain water automatically in the enterprise.

The redundant control theory was applied in the vacuum absorption system of wall cleaning robot,and its feasibility was analyzedt,hen a model was established.

According to air flow control principle,by adoption of pneumatic line drive technology and vacuum suction technology,pneumatic feeding mechanism was manufactured.

In this paper,the biodegradable seeding containers from waste cotton linters and used paper were deve loped by making fibers in the linters/paper pulp adhere to the surface of a net mold under vacuum suction.

A novel wall-climbing robot mechanism is presented based on planetary gear train movement and biped vacuum suction principle.

A new way to pick up tissue for bio-microdissection:vacuum adsorption;

Adsorption force calculation for vacuum adsorption of target Pellet;

The design adopts the vacuum adsorption technique and in-wheel driving, and makes the cleaner adsorbed on the working surface and run smoothly, matches the clean machine of revolving brushes and single-chip microcomputer control system.
