Forming methods, molding dies, and ceramics for large-size thin-sheet ceramics

ActiveCN122323356BAvoid free reboundAvoid edge scratches
This invention relates to a method for forming large-size thin-plate ceramics, a forming mold, and the ceramic itself, belonging to the field of ceramic material forming technology. The method includes: filling, floating film floating, pressurization, depressurization-demolding-depressurization, and isostatic pressing steps. The depressurization-demolding-depressurization step includes: gradually depressurizing the upper pressure head while retaining a pre-set pressure; demolding, keeping the sample clamped between the upper and lower pressure heads, and lowering the floating mold until the sample is completely removed; and secondary depressurization: slowly reducing the pre-set pressure to zero, and retracting the upper pressure head to its initial position after leaving the sample. This invention effectively solves the problems of easy cracking, uneven density, difficult demolding, and easy deformation and damage during isostatic pressing of large-size thin-plate ceramics during the forming process, thereby enabling the preparation of high-quality, high-density, and uniform large-size thin-plate ceramic products.

A light-emitting diode and a light-emitting device

PendingCN122294663AReduce equivalent resistanceIncrease the number of leadsCurrent distributionElectrical connection
This application provides a light-emitting diode (LED) and a light-emitting device. A first electrode is formed on one side of the first semiconductor layer of the LED. The first electrode has multiple body portions distributed on opposite sides of the LED and multiple extension portions electrically connected to the body portions. The multiple extension portions include main extension portions and secondary extension portions distributed in a first direction and a second direction. This design increases the number of body portions of the first electrode and adaptively increases the number and distribution of the extension portions, thus shortening the current conduction distance, improving current spreadability, and making the current distribution of the LED more uniform. Simultaneously, the increased number of body portions correspondingly increases the number of leads between the LED and external circuits, thereby reducing the equivalent resistance of the LED and ultimately lowering the voltage of the LED package, reducing input power, and thus improving the photoelectric conversion efficiency of the LED.

A sowing method for improving the uniformity of sowing of light forage grass seeds

This invention discloses a sowing method for improving the uniformity of light forage seed dispersal, relating to the field of intelligent agricultural sowing technology. The method includes: S1, obtaining soil moisture weight and temperature influence factor data for the target plot from a preset database; constructing an initial distribution map by integrating soil moisture boundaries and temperature distribution differences; calibrating the data according to regional crop characteristics to determine the basic influence parameters of seed drift within the plot; S2, based on the basic influence parameters of seed drift, combined with terrain undulation constraints and drift influence gradients, dividing the plot into regions; and adjusting the regional overlap ratio through boundary dynamic correction technology to obtain a preliminary zoning layout. This sowing method for improving the uniformity of light forage seed dispersal significantly enhances the accuracy and efficiency of large-area grassland sowing operations and is suitable for high-precision forage planting scenarios such as degraded grassland restoration and ecological engineering construction.
