The invention provides a manufacturing method of a flexible display panel. The manufacturing method comprises the following steps of providing an array substrate, wherein the array substrate comprisesa semiconductor layer, the flexible display panel is divided into adjacent pixel region and bending region, and the pixel region comprises the semiconductor layer; digging a second groove in the bending region, wherein the second groove forms a stage structure in the array substrate, and the stage structure extends from the interior of the array substrate to a direction opposite to the inner wallof the second groove; filling the second groove with an organic material, and an inwardly concave conical groove is formed in the surface, flush with the array substrate, of the organic material filled in the second groove; and manufacturing a source, a drain and source and drain routing lines on the array substrate, wherein the source and the drain are connected to the semiconductor layer, and the source and drain routing lines cover the conical groove. By virtue of the above-mentioned setting, the bending degree of the source and drain routing lines in the position of the conical groove canbe lowered, thereby effectively relieving the problem of cracking of the source and drain routing lines in the position of the conical groove. The invention also provides the flexible display panel.

The invention provides a slope widening method of an open-pit sandy soil slope. The slope widening method comprises the following steps: step a, stripping sandy soil by a set height downwards on one side, close to the slope surface, of the top of the slope to form a step; step b, moving outwards towards the slope surface by a set width, and continuously stripping the sandy soil by the set width downwards to form a new step; and step c, repeating the step a and the step b, and when the height of the left sandy soil of the slope is smaller than the maximum digging height of an electric shovel, stripping the left sandy soil by use of the electric shovel to form a bottommost step. According to the slope widening method of the open-pit sandy soil slope, a combined section of a plurality of small steps is formed from top to bottom, and when the height of the left part after the sandy soil is stripped is smaller than the maximum digging height of the electric shovel, the left sandy soil is directly stripped by use of the electric shovel. Compared with the prior art, the landslide can be prevented, and therefore, a safety protective flat plate adopted in the prior art for guaranteeing safety can be cancelled, and consequently, the bottom mining limit is widened and the resource recovery rate is increased.

A swash plate type opposed-piston two-stroke external-combustion engine, comprising a cylinder block, a main shaft hole is opened in the middle of the cylinder block, six axially penetrating cylinders are evenly arranged on the outer periphery of the main shaft hole, and two front and rear cylinders are arranged opposite to each other in the cylinder. There are two pistons, and the front and rear ends of the cylinder are equipped with compressed air rotary valves, and the middle of the cylinder is equipped with a working rotary air valve. Among the twelve pistons, nine pistons take in air from the environment through the compressed air rotary valves and perform one-stage compression. To the gas storage branch pipe, the three pistons take in air from the gas storage branch pipe through the compressed air rotary valve and perform secondary compression to the combustion chamber. Among the six cylinders, three cylinders perform primary work, and three cylinders perform secondary work. The first-stage work cylinder is the cylinder where the piston of the second-stage compression is located, and the second-stage work cylinder is the cylinder where the two pistons before and after the first-stage compression are all performed. This design improves the utilization rate of heat energy.

The present invention relates to a semiconductor device, its preparation method, and an electronic device. The method includes: providing a substrate, forming a protrusion having a first slope on the substrate, and the acute angle formed by the first slope and a horizontal plane is 50- 60°; a thin film layer is deposited on the protrusion to form a second slope on the first slope, and the acute angle formed between the second slope and the horizontal plane is 30-40°. The advantages of the present invention are: (1) The present invention breaks through the limitation of the 50-60° slope in the prior art, and prepares a slope with a gentler slope. (2) The inclined surface prepared by the method of the present invention is greatly improved by the deposition method compared with the inclined surface obtained by etching, which is beneficial to the subsequent process and further improves the performance of the semiconductor device.

The invention discloses a mosquito repelling device, and belongs to the fields of industrial hygiene and environmental protection. The scheme lies in that the mosquito repelling device includes a mosquito coil and a mosquito coil holder in which the mosquito coil is installed, the mosquito coil includes an inverted spiral tapered upper coil and a spiral tapered lower coil, and the mosquito coil holder includes an upper circular ring, a lower circular ring and a central shaft connected to the centers of the upper and lower bottom surfaces; and when the mosquito coil is hung on the mosquito coilholder, an upper coil body abuts against a protrusion arranged on a pin shaft of the upper circular ring of the mosquito coil holder, and the other end of the pin shaft is connected to the edge of the upper circular ring through a compression spring, when the mosquito coil body abutting against the protrusion of the pin shaft is burned, the pin shaft is subjected to a resultant force along the direction of an elastic force of the compression spring to the pin shaft, a supporting block abutting against the inclined surface of the pin shaft and arranged in the central shaft is pressed to be moved downwards while the pin shaft moves, and when the pin shaft is taken out, the supporting block is restored to an original position through a pull spring. The mosquito repelling device provided by the invention can be used in areas such as factories requiring large-scale killing of mosquitoes.
