Latest Patents

One of Kawamoto's latest patents is for a thermoelectric refrigeration material and method of making the same. This invention focuses on improving the crystallinity of a bismuth-antimony (Bi-Sb) system to enhance its thermoelectric conversion characteristics. By depositing bismuth, antimony, and silicon monoxide on a substrate in a thermally nonequilibrium state, Kawamoto aims to create a thin film crystal with a granular structure. This advancement allows for selective variation of thermal conductivity, which is crucial for optimizing the figure of merit Z, thereby improving thermal conversion efficiency.

Another significant patent is for an automatic ice maker and household refrigerator equipped with it. This innovative ice maker features an ice tray that is supplied with water to create ice cubes. After the ice-making process, the tray is inverted to release the ice cubes, while chilled air flows along the underside of the tray. This design ensures that the water at the bottom freezes first, resulting in opaque ice cubes. A thermistor is included to sense the temperature and determine when the ice-making process is complete.
