The invention relates to a non-sphere micro-lens array manufacturing device, which solves the problem that during the manufacture of the prior micro-lens and array devices thereof, the surface shape of the micro-lens is beyond control and real-time detection of optical performance of the surface of the micro-lens is impossible. The device comprises a main support, an injector, an upper electrode,a transverse detection optical circuit, a longitudinal detection optical circuit, an annular, an ultraviolet source and so on, wherein a liquid box is arranged under the injector, and one side of theinjector is provided with the upper electrode and a specimen stage. An undersurface of the specimen stage and an upper surface of the upper electrode are provided with tin indium oxide coatings to form a parallel-plate capacitor type electric field. The injector injects a liquid drop between the specimen stage and the upper electrode, the electric filed controls the surface shape of the liquid lens, the transverse detection optical circuit carries out real time detection of the surface shape of the liquid lens, the longitudinal detection optical circuit detects a focused spot, aberration analysis is carried out according to the surface shape and an image of the focused spot and the annual ultraviolet source solidifies the liquid lens when proper surface shape and focused spot are proper, so a solid non-sphere micro-lens with excellent optical performance is obtained. The device has the advantages of simple process, high repetitiveness and low cost.

The invention relates to a front chest piece manual sewing method for manufacturing a top grade suit or coat. A front chest piece comprises a front left chest piece and a front right chest piece which are formed by combined sewing of a chest lining, a horsetail lining and a chest cotton lining respectively, the front chest piece manual sewing method comprises front left chest piece sewing and front right chest piece sewing, each sewing method comprises the steps that (1a) drawing of three large manual sewing areas on the front left chest piece after overlaying of up and down linings; (1b) manual sewing of an upper area; (1c) manual sewing of a left area; (1d) manual sewing of a right area; the front chest piece sewing method and the left and right chest piece sewing method are opposite in the left and right; the method has the advantages that the manufacturing process is simple and reliable, the human body chest shape can be manufactured excellently, the conditions of hanging front, empty back or the like of a ready-made garment are overcome, the top grade suit or coat with good body suitability can be manufactured and the like.

The invention relates to a turbocharger. The turbocharger comprises a middle body. The two ends of the middle body are connected with an impeller and a turbine correspondingly through shafts, the outside of the impeller is covered with a pressure air shell, a shock absorber is installed on the lateral surface of a pressure air shell outlet, an air inlet is formed in one side of the impeller, and the turbine is provided with a turbine air inlet and a waste gas outlet. A turbine shell of the turbocharger is not provided with a bypass vent valve but the shock absorber, so that the knock and surge phenomena are avoided. Pressure is adjusted through a precise spring of the shock absorber sensitively and reliably, and installation, debugging and repairing are convenient. The turbocharger is adjusted through an adjusting screw when matched with an engine and debugged, operation is simple, accurate and reliable, and a technician of an engine factory assembly production line and a vehicle repairing technician can install and debug the turbocharger according to the power, displacement and revolution number of the engine to meet the ideal standards.

The invention discloses a tank-type container tank box tank body and frame connecting structure. The tank-type container tank box tank body and frame connecting structure comprises a frame and a tank body which is mounted in the frame; the frame comprises two end frames, and a lower side beam and an upper side beam which are connected with the two end frames; inclined struts are arranged on each end frame; a connecting cylinder is arranged at each of the two ends of the tank body; one end of each connecting cylinder is welded with the tank body; the other end of each connecting cylinder is welded with the end frame at one end; the tank body and the connecting cylinders are all mounted in the frame. The redundant strength of corner posts of the frame is fully utilized, so that the tank box is compact and light in structure and the structure optimizing effect is improved; the tank-type container tank box tank body and frame connecting structure has the characteristics of cost conservation, simple manufacturing process, and reliability.

The invention discloses a separate Hopkinson bar impact test device, which is suitable for the Hopkinson bar impact test of bulk / soft materials, comprising a casing (1) and a nut (2) for fixing a sample pad , exhaust components, sample pads (4) and casing supporting parts, the sample pads (4) are respectively located on the left and right sides of the inside of the casing (1), between the two sample pads (4) It is a sample chamber, and the nuts (2) for fixing the sample pad are distributed on the wall of the casing (1); the exhaust part is an exhaust hole (3) or an exhaust groove (9); the device mainly It solves the problem that the bulk / soft material cannot be fixed in the separated Hopkinson rod impact test, and the air in the casing cannot be discharged when the sample in the casing is impacted at high speed, which affects the test result. At the same time, it can display the sample during the test State, and the production process is simple, reliable, easy to use, easy to operate.
