The forming method of the fast recovery diode device comprises the following steps that a monocrystalline silicon material grows, a silicon substrate is formed, the silicon substrate comprises a front face and a back face which are oppositely distributed, and the oxygen concentration in the silicon substrate is lower than 5 ppma; forming an epitaxial layer on the front surface of the silicon substrate by adopting an epitaxial process; and forming a front device structure on one side, deviating from the silicon substrate, of the epitaxial layer. The power consumption and the manufacturing cost of the fast recovery diode device are reduced.

The utility model relates to the technical field of refrigerator condenser, especially relates to rear cover condenser. Including condensing pipe, the spiral setting of condensing pipe, and the spiral structure gradually protrudes from outside to inside and presents the prism platform shape, and the condensing pipe is buckled and is equipped with the truss of multiple groups of interval settings, and multiple groups of trusses are detachably connected with the frame, and the frame is equipped with the edge foot. With condensing pipe directly instead of radiating window outer cover, the prism of condensing pipe bending is directly suspended and is installed, and the production cost of outer cover is saved, and still has the ventilation and ventilation function of radiating window, and the condensing pipe is not shielded outside, can directly with air convection, the heat dissipation is more uniform and efficient, can effectively weaken the local overheating phenomenon of the left and right side edge of refrigerator, improves the overall performance and user experience of refrigerator. The frame can be directly fixed on the refrigerator side plate, compared with the originally condensing pipe pasting type installation in the inside of side plate, this kind of outer suspension type installation operation is more convenient, reduces multiple processes, greatly reduces the labor intensity of staff, improves production efficiency.

The invention relates to the technical field of biological medicine, in particular to a multi-sucker-specification multi-purpose sucker box which comprises a middle plate frame body used for containing suckers, a cover body used for being movably connected to the top end side or the bottom end side of the middle plate frame body and a plate sealing film used for being bonded to the top or the bottom of the middle plate frame body. A middle plate hinge assembly and a middle plate switch assembly are connected to the two opposite faces of the outer wall of the middle plate frame correspondingly, and the two middle plate hinge assemblies and the two middle plate switch assemblies are arranged diagonally. Compared with a traditional hinge type suction head box, the suction head box is more stable by adopting the same upper cover and lower cover of the suction head box and designing a hinge structure, the use function of the suction head box is not affected when part of the hinge structure is damaged, meanwhile, waste can be utilized, and certain cost is reduced; moreover, the suction head box can be flexibly matched according to actual use requirements in the actual assembly process, and the internal space of the suction head box is fully utilized, so that the requirements of convenience in use and cost reduction are met.

The invention discloses an intelligent mold-free wall type sole pressing machine and a pressing method thereof.The intelligent mold-free wall type sole pressing machine comprises a base, a first flexible filler, a first driving device, a second driving device, a second flexible filler and a liquid driving device, the first flexible filler is provided with a first inner cavity, the first flexible filler is arranged on the base, the first inner cavity is provided with a first channel, and the first channel is provided with a second channel; the two side wings are arranged on the bottom carrier in a swinging mode, the two first driving devices are arranged on the outer sides of the side wings correspondingly and used for driving the side wings to swing, the second flexible filler is provided with a second inner cavity, and the two sets of second flexible filler are located between the ends of the two side wings correspondingly. The second driving device is used for driving the second flexible filler to move between the positions extending into the middle parts of the two side wings or the positions far away from the middle parts; and the liquid driving device is used for conveying liquid with preset pressure to the first inner cavity and / or the second inner cavity and forcing the inner walls of the first flexible filler and the second flexible filler to deform.

The utility model belongs to the technical field of building construction, and particularly relates to a water stop fixing device for hydraulic engineering, which comprises a first positioning support for fixing the middle of a rubber water stop and a second positioning support for fixing the end of the rubber water stop. The first positioning supports are symmetrically arranged on the two sides of a joint and comprise clamping plate assemblies and steel bar sets, the clamping plate assemblies are fixedly connected with a concrete side formwork through the steel bar sets, the clamping plate assemblies are provided with adjustable openings, and the edges of the rubber waterstop are embedded into the openings. The first positioning base plate and the first supporting plate are perpendicularly arranged and fixedly connected, the first movable plate is parallel to the first positioning base plate and movably connected with the first supporting plate, and the rubber waterstop is clamped between the first positioning base plate and the first movable plate. The rubber waterstop mounting structure has the advantages that the mounting stability and the waterstop effect of the rubber waterstop are improved.

The invention provides a composite current collector with reserved welding and a preparation method thereof, the composite current collector with reserved welding comprises a conductive substrate, the conductive substrate comprises a current collector coating part and a reserved welding part, the thickness of the reserved welding part is greater than that of the current collector coating part, and the thickness of the reserved welding part is greater than that of the current collector coating part. The upper surface of the welding reserved part is flush with the upper surface of the current collector coating part, the lower surface of the welding reserved part is higher than the lower surface of the current collector coating part, and the lower surface of the current collector coating part is covered with a non-conductive base layer. And conductive coatings are arranged on the lower surface of the non-conductive base layer and the lower surface of the welding reserved part. Through the arrangement, the conductive substrate is made of the pure metal foil, and meanwhile, the welding reserved part is also made of the pure metal foil, so that a tab and an adapter plate do not need to be welded again when a battery is prepared, the welding reserved part of the composite current collector can be directly cut into strips, and the production efficiency is improved.
