Latest Patents
Horiuchi's latest patents include a gypsum-based investment material composition for casting and a method for manufacturing this composition. The first patent provides a gypsum-based embedding material composition that is useful for forming a rapid-heating type gypsum-based embedding material. This invention involves a process where a malaxation liquid is added to a gypsum-based powdery embedding material composition, which is then heated in a high-temperature furnace. The composition contains co-pulverized materials such as calcined gypsum, quartz, and cristobalite, along with a moisture-retaining component. The average particle diameter of the composition is 30 μm or less.
The second patent focuses on a method and apparatus for evaluating the scattering property of a powder. This method involves dropping a powder onto a liquid in a box, allowing it to scatter as dust, and measuring the dust concentration in the air using a dust meter. This innovation aims to provide a clearer evaluation of powder scattering properties.
