Latest Patent Applications
Han Il Chung has submitted several patent applications, including:
1. **Quantum Dot Preparing Method** - This method involves preparing a first solution containing at least one first cation precursor and a second solution containing at least one first anion precursor. The process includes mixing the two solutions at temperatures ranging from 20° C. to 130° C., raising the mixture's temperature to 300° C. within one minute, and then cooling it to 100° C. or lower within one minute to form a core. The first cation precursor includes an indium oxo cluster (In-Oxocluster).
2. **Hose Clamp** - This invention features a clamp body formed by bending a resilient plate-shaped member made of stainless steel. It includes a fastening screw and a plurality of screw holes for engagement. Additionally, it has a compensation bead that helps to firmly fasten the hose, which reduces in diameter due to long-term use. The design incorporates a plastic deformation prevention means to maintain the elasticity of the compensation bead.
