Latest Patents

One of his noteworthy inventions is the "Spiral-Orifice Ceramic Filter for Metal Casting." This inventive filter features spiral channels and dual drain openings, strategically arranged in a ceramic substrate. By utilizing this spiral design, the molten metal generates a centrifugal force during its flow, enhancing the separation of inclusions. The filter comprises 90-95 wt % of MgO, 4-8 wt % of SiO₂, and 2-4 wt % of ZrO₂, granting it significant strength at normal temperatures while allowing thermal impact resistance capable of withstanding molten metal temperatures of 1700 °C or higher. Additionally, the ceramic substrate and spiral channel are coated with a layer of functional oxide made from compounds like CaO·2AlO₃ and TiO₂.

Another significant patent is the "Method for Valuation of Image Dark Data Based on Similarity Hashing." This method offers a systematic approach to evaluating dark datasets by incorporating a trained deep self-taught hashing algorithm. The process begins with acquiring the dark dataset, followed by generating hash codes for each image, constructing a hash map, assessing the significance of each node, and ultimately providing users with the top images based on their significance scores.
