The application discloses a chuck assembly and a semiconductor device, relates to the technical field of semiconductor devices, and comprises a chuck and one or more shaft cylinders, wherein the last shaft cylinder of the plurality of shaft cylinders or one shaft cylinder is connected with the chuck, the inside of each shaft cylinder is provided with a central hole, the central hole is provided with a balance mass and an elastic damping piece, and the elastic damping piece is sleeved with the balance mass to form a balance mass-spring-damping system. The chuck assembly is sleeved with the balance mass through the elastic damping piece to form the balance mass-spring-damping system, the balance mass-spring-damping system generates reverse vibration matched with the vibration of the chuck, micro-vibration generated between the disc surface of the chuck and the contact surface of the substrate is inhibited, generation of friction particles is reduced, stability and cleanliness of a core area of a process environment are improved, process quality of a deposited film is improved, and the needs of high-end processes for extremely low defect rate and ultra-high uniformity of the deposited film are met.

The present application relates to the field of ecological revetment in the field of hydraulic engineering, and particularly relates to a riprapping ecological revetment system suitable for water level drawdown. The system comprises an ecological soil base layer, a filter layer, a riprapping revetment, a simulated wood pile scour protection belt and a planting groove; the ecological soil base layer has a compaction degree of greater than or equal to 93%, providing a dense support; the filter layer ensures smooth seepage and prevents soil loss; the riprapping revetment is formed by stacking large-diameter block stones according to gradation, forming a rigid skeleton resistant to scour; the planting groove is fixed in the riprapping structure, providing space for vegetation and anchoring the surface riprapping. The present application forms a closed-loop protection system through the cooperation of the five, effectively solving the problems of traditional riprapping revetment, such as easy scouring and instability during water level drawdown, and high maintenance cost, and has the advantages of scour resistance, ecology and universality, and is suitable for water level rapid rise and fall scenes such as regulating and storing lakes, reservoir drawdown zones, tidal river shorelines and the like.

The utility model relates to a vehicle detection system which comprises a parking garage, an opening and closing door is arranged on one side of the parking garage, four limiting areas are arranged on the bottom wall of the parking garage in a matrix mode, each limiting area comprises a plurality of penetrating holes formed in the bottom wall of the parking garage in a matrix mode, and the vehicle detection system further comprises a machine box. In an initial state, four groups of multiple blocking rods do not protrude out of through holes, the opening and closing door is opened, a vehicle runs into the parking garage, four hubs of the vehicle are stopped on four limiting areas, the hubs and the limiting areas are in one-to-one correspondence, two driving mechanisms are driven to start working according to the size of the vehicle, and the driving mechanisms drive moving blocks to slide along sliding rails; the lifting mechanism drives a plurality of blocking rods on the lifting mechanism to penetrate out of the penetrating holes, and the four sets of blocking rods limit and block four hubs of a vehicle, so that the problems of unbalance loading and translation in the moving process of the parking garage are effectively prevented.

The application belongs to the technical field of wood processing tools and discloses a wood multidirectional cutting guide plate with a positioning scale, which comprises a guide plate main body, a mounting groove is formed in the side surface of the guide plate main body, and a ruler is inserted and mounted in the mounting groove. The positioning protrusion of the positioning column cooperates with the positioning gap in the convex column positioning groove, can be directly clamped into the gap corresponding to the preset angle, and mechanical positioning is realized. This structure does not need manual repeated measurement, controls the angle error in the mechanical tolerance range, can quickly switch various cutting angles, solves the problem of the traditional mode of "depending on experience and large error", cooperates with the length positioning of the ruler, can complete straight line cutting, can realize 45° bevel cutting, arbitrary angle mortise and tenon cutting and the like, covers the diversified needs of furniture manufacturing, decoration and the like scenes, breaks through the limitation of the traditional guide plate "single function", meanwhile, the plug-in connection of the positioning column and the positioning groove limits rotation, the magnet adsorption cutting platform prevents translation.

The utility model belongs to the technical field of automobile welding fixture, concretely, the utility model relates to a quick overturning step platform of automobile welding fixture, a quick overturning step platform of automobile welding fixture, including the fixture main body, be provided with overturning structure on the fixture main body, be provided with support platform on the overturning structure, when needing to use support platform to carry out the welding operation, the operator will be in the vertical state support platform and turn down around the pivot, until support platform presents the horizontal state first support plate and second support plate respectively with support platform bottom abut, provide firm support for support platform. Subsequently, the first bolt is inserted into the first connecting hole and the second connecting hole, realizes the fixation of support platform and second support base, and the operator can stand on the support platform safely and weld the top of the car body.

The utility model belongs to the field of quality inspection equipment, specifically is a kind of quality inspection equipment for optical lens processing, including base;The upper end of the base is connected with air float clamp, the outside of air float clamp is connected with adjusting assembly, the upper end of the base is connected with quality inspection assembly;The air float clamp includes disc, the disc is fixedly connected at the upper end of base, the outside of disc is fixedly connected with ring one;By setting air float clamp, when carrying out quality inspection to optical lens, open air pump, air pump will compressed air pass through gas pipe, main pipe, communicating pipe, finally respectively input each annular pipeline, finally from jet pipe spouts, the airflow formed air film can be placed on its optical lens suspended support, to optical lens play the role of supporting positioning, it is convenient to carry out quality inspection to optical lens, and will not directly form contact with optical lens, prevent because mechanical clamping easily scratch mirror surface coating.

A blade assembly for securing a blade to a slicer, a slicer equipped with the blade assembly, and a method for operating the blade assembly to secure the blade to and release it from the slicer. The blade assembly includes a blade holder with a blade support surface, a blade supported on the blade support surface, and a clamp having a base portion adjacent to the rear edge of the clamp and a blade engagement portion adjacent to the front edge of the clamp. The blade assembly applies a clamping force to the clamp to secure the blade to the blade holder. The clamp is prevented from translating relative to the forming blade in the forward direction of the blade assembly when the clamping force is applied, and / or allows the clamp to be removed by translation in the forward direction.
