Latest Patents

One of Kato's latest patents is a method for manufacturing an electrophotographic toner. This method focuses on creating toner particles with a mean diameter between 5 µm and 10 µm. The process begins with coarsely pulverized particles, which are first reduced to medium pulverized particles with a diameter of more than 10 µm and not more than 19 µm. These medium particles are then further pulverized to achieve the desired small diameter. The final step involves classifying the small diameter particles using a rotor-type classifier. Another notable patent involves a mill designed with a partition within the milling chamber. This innovative design enhances milling efficiency by dividing the chamber into two guide paths, allowing for better particle classification and recycling of materials.
