A kind of rigid and sequential mould opening mechanism and its working process are inˉtroduced.

The structural design of a stacked multi-cavity injection mould for a hook was introduced;and the research on the mould cavity,main runner,mould opening mechanism and guiding mechanism were analyzed.

Analysis of return harness of negative cam shedding mechanism;

Principles analysis and discussion of TOYOTA electronic shedding mechanism;

Analyses made on the stability of heald frame motion and the bearing force of shedding device show that a positive shedding mechanism is superior to a negative one,while electronic revolving dobby represents a development trend in the future due to its application to a wide range variety.

Techniques of dampers for spacecraft deployment mechanism;

Reliability analysis of the deployment mechanism of a large satellite antenna based on the non-probabilistic model;

For the shortage of the system reliability data in the initial stages of the design of spaceborne antenna deployment mechanism,a unascertained method for the system reliability allocation is proposed.

A surface inspection system composed of optical microscope,digital imaging system and unfolding mechanism has been developed to provide image data for detecting natural defects on the surface of polished Si_3N_4 balls.

The operation principle of meridian unfolding mechanism of Aviko K type bearing ball out surface inspection machine is introduced in this paper.
