A review of step height metrology techniques used in nanotechnology applications is presented.

The Study on Step Linear Output Control;

The programming tools and motion control system of log shape recognition machine incept software instructions,and they realize numerical control shape recognition in accordance with calculation and system instructions to control the motion of each stepper motor.

Development of Mechanical Stepping Transportation Machinery;

A standing-wave-type stepping ultrasonic motor using the alternative operation of two bending vibration modes on the stator has no accumulative errors without the feedback.

How to program with timer and stepping instruction was expatiated.

A large-travel high-resolution step rotary micro-actuator with a discrete layout was developed based on the step moving principle.

According to step moving principle, a discrete layout has been developed .

Several projects were proposed in allusion to the problems which were reflected in the old walking beam heating-furnace hydraulic system in Si-steel mill, and the best of which were confirmed according to the principles proposed by workers in the mill.

Taking normal circulation of heating furnace walking beam for example, the structure and operating principle of three main current change valves are raised with the emphasis on the pressure oil change under each action.

ing kiln and introduces the structural features, technical parameters and specification of 1750 ℃ high temperature walking beam type electric tunnel kiln.
