The invention provides a system and method for achieving natural striding, falling and filling of coal beds, flexible roadway protection and complete gob-side entry retaining. Gob-side entry retaining is conducted in a primary mining retaining and protecting area, small coal columns are reserved on one side of a goaf to support and block gangues sliding down from the goaf, anchor bolt support is conducted in a roadway, and three types of roadway-side supporting technologies are adopted in a normal recovery period according to the thickness of the coal beds and the lithology of a top plate and a base plate. According to the system and method, influences of coal column concentrated stress are eliminated, the roadway strata behavior appearing degree is greatly lowered, the gob-side entry retaining is guaranteed to meet requirements for safety in production, disaster accidents such as fire disasters and coal and gas outbursts caused by the reserved coal columns are eliminated, the roadway digging rate is lowered, the ton-coal cost is reduced, the working environment is improved, the high yield and the high-efficiency are achieved, the working face is continuously and rapidly pushed forward, and a solid foundation is established for eliminating the short supply of successive excavating. The medium-inclining and sharp-inclining coal bed goaf top plate naturally strides, falls and slides down to conduct filling under the action of the gravity, and the filling cost of the top plate is zero.

A pre-control method of head and tail shapes of continuous casting slab for reducing the removed amount from the head and tail of hot-rolled intermediate slab. By a pre-control cutting process for the head and tail shapes of continuous casting slab, the slab is cut into a shape such that its head end surface dents inwards and its tail end surface extrudes towards outside of the slab. In the pre-control cutting process, the head and tail shapes of the slab is cut in accordance with the curve which is linearly symmetrical with respect to the width center of the slab, and the arch height (i.e., the maximum value of the denting portion of the head or the extruding portion of the tail) is controlled in the range of 0 mm to 50 mm. In such a manner, the length of the non-uniform deformation portions of the head and tail of the intermediate slab can be significantly reduced, and thus the reduction of the removed amount from the head and tail of hot-rolled intermediate slab is achieved.

The invention provides an evaporator source, an evaporation device and an evaporation method, and belongs to the technical field of evaporation equipment. The problems that by means of an existing evaporator source, all organic evaporation chambers are stopped being used due to the fact that a nozzle is blocked, organic evaporating materials are wasted seriously, and the yield and the device performance are lowered can be solved. The evaporator source comprises a crucible used for generating evaporating gas and a crucible nozzle used for making the evaporating gas spray out of the crucible, and the evaporator source further comprises a blocking heater used for heating the crucible nozzle.

There is described a disk processing and manufacturing equipment in which the processing chambers are stacked on top of each other and in which the disks move through the system on disk carriers which are adjustable to take disks of varying sizes. The disks enter the system through a load zone and are then installed into disk carriers. They move in the carriers sequentially through processing chambers at one level and then move to the other level in a lift or elevator. At this other level, the disks again move sequentially through the system on that level and then exit at an unload zone.
