Random setting and delayed explosion control circuit design;

The method of setting synthetic corrections is annoyingly,and wastes many ammunitions.

Based on the analysis of induction setting in muzzle,the finite element model of the transmission coil has been established.

Research on Main Shaft s Skip Weight-fixed Loading System of Coal Mine;

The new system implements automatic and weight-fixed loading.

The structure,location equipment,clamping device of the fixtures and connection way with the machine spindle were detailedly analyzed.

For the location of the detector of the mechanics system,the circuit of the location equipment was designed,the magnifying circuit of the sensor signal and the circuit of the serial communication were mainly designed.

The article analyzes the jig's structure,registration device,clamping device and the connection way with the machine spindle.

The paper analyzes that the shackle registration device,currently applied in the OCS,is easy to cause the accident between pantograph and OCS, and it introduces the characteristics of the structure and application of the hinge jointed anti-rise type registration device.

It introduces the design characters, construction methods, dynamic ascending of registration device, status of activated forces and inspection methods of slope of registration device, and gives the maximum values of the slope of the registration device of Re200C OCS in the circumstances of cant of outer rail in various track lines.

After disadvantages of fruit grading method only based on machine vision are analyzed, the new method of combining machine vision with oriental device is put forward in the paper.
