The invention provides a brazed layer predeposition method, which comprises the following steps: A: vacuum sputtering coating a seed layer, and B: depositing each layer through a manner of sequentially alternating a gold layer and a tin layer. Through the scheme, the brazed layer predeposition method not only solves the problems existed in the prior art, and has the obvious advantages that aiming at a hybrid integrated circuit adopting braze, a process method by adopting soldering paste or soldering flux pieces in traditional soldering is improved, a layer of soldering flux layer with each component weight ratio being equivalent to components of the soldering flux pieces is deposited on a circuit soldering face (generally refers to a back face), the circuit can be directly placed on a soldering position when soldering is carried out, and soldering is realized through heating. Due to the technology, the processing workload for forming the soldering flux pieces can be reduced, and wastes caused by position offset among soldering positions, the soldering flux pieces, and the circuit to be soldered when soldering is carried out can be reduced.

The invention relates to a punching and riveting device of a combined connecting movable sheet used on a hinge. The device comprises a fixing mold base, an upper mold and a lower mold. Three punching needles, two riveting hole punch needles and a pair of shear type punches are respectively arranged at the front end of the upper mold. A perforation is arranged in the middle of the upper mold, a slider is arranged on the perforation, and two separation punch needles with elastic elements are mounted below the slider. A forming punch is arranged at the back end of the upper mold. A control system is arranged on the upper mold and is connected with a connection power rod. The lower mold is provided with perforations corresponding to the upper mold punching needles, the riveting hole punch needles, the shear type punches, the separation punch needles and the forming punch. Two or more than two movable ejector pins with the elastic elements are distributed on the lower mold plate. The perforation corresponding to the forming punch is arranged on the lower mold. A returned material device is arranged above the lower mold. The invention integrates the punch processing and the riveting processing for the connecting movable sheet on the hinge, greatly reduces the processing time, and greatly improves the processing efficiency and saves the production cost.

An ecological garden landscape pet dog public toilet relates to a pet dog public toilet. The present invention aims to solve the environmental impact caused by pet dog excretion caused by peculiar smell and excrement pollution in the existing residential areas, the excrement of pet dogs is difficult to handle, and the existing pet toilets for pet dogs excrete are poor in convenience and require water pipeline engineering The connection causes the problems of high investment, large engineering volume and lack of landscape effect.

The pet dog public toilet solves the problems of peculiar smell and environmental pollution caused by pet dog excretion, has low manufacturing cost, has the functions of landscape and lighting, and can also prepare organic fertilizers.

The invention relates to a method for adjusting the matching degree of forming parameters of a coal ash autoclaved standard brick. The adjusted parameters comprise the following important parameters including dry raw material ratio, feeding door opening time, material distributing bed moving speed and rocking bar swinging times, wherein I, the dry raw materials comprises the following components in parts by mass: 46 to 50 parts of coal ash, 7 to 9 parts of quick lime, 3.6 to 4.4 parts of dust-removing lime, 20 to 24 parts of gravel and 16 to 20 parts of coarse slag, wherein the granularity of the gravel is less than or equal to 5 mm and 9.4 to 10 percent of water is added into the dry materials; II, the feeding door opening time is controlled to be 0.1 to 0.3 second; III, the rated value of the material distributing bed moving speed is 1.8 to 2.2 m / s and the normal set value is 70 to 80 percent of the rated value; IV, technical parameters of material distribution are controlled, i.e., a rocking bar swings for 5 to 6 times and a mould frame charging depth is 220 mm. By adopting the method for adjusting the matching degree of the forming parameters of the coal ash autoclaved standard brick, the blank formation qualified ratio of manufactured standard bricks is high.

The invention provides a processing method for a high-precision Ti capillary pipe fitting and a pipe grinding assembly used in the processing method. The precise Ti capillary pipe fitting is produced by the steps of adopting a laser diameter measuring instrument and an eddy current flaw detector for optimally selecting pipe blanks, adopting a specific process to draw Ti capillary pipes, adopting ultrasonic waves to clean the capillary pipes, blanking the bundled capillary pipes by adopting a specific fastening clamp, and preparing the pipe grinding assembly, and finely grinding the end faces of the capillary pipes on a grinding machine. The method has the technological characteristics of good product quality, high finished rate, higher production efficiency, less equipment investment and suitability for production in batch.

The invention relate to a center hole benchmark correcting method reducing cutting torque. The center hole benchmark correcting method includes the following steps that a center hole benchmark correcting process of a journal type typical blade part machining technology is selected; equipment for machining in the center hole benchmark correcting process is selected; the positioning benchmark of a clamp and the equipment is selected, and the positioning benchmark of the clamp and a part is selected; a center hole benchmark correcting tool for reducing cutting torque is designed; the coaxiality tolerance actual values of the benchmark of a center hole are detected before heat treatment and semifinishing in a journal type blade in the machining process, and an average value is calculated; the center hole benchmark correcting tool is used for machining and correcting the center hole of the part, and whether the coaxiality tolerance value of the journal of the part subjected to external grinding conforms to the tolerance or not is judged; machining parameters are set; and the differences of the coaxiality tolerance actual values of the benchmark of the center hole of the part are compared. According to the center hole benchmark correcting method reducing cutting torque, the qualification rate of the machining process with the center hole of the journal type blade as the benchmark is increased, waste products caused by profile deformation when the coaxiality of the center hole is not qualified are reduced, the machining efficiency is improved to be more than 200%, and the qualification rate is more than 90%.
