Latest Patents

One of his latest patents is a die for use in an underwater granulating apparatus. This invention features two rows of nozzles, with open ends formed as orifices of a die that communicate with introducing slots of orifice units. Additionally, jackets for temperature regulation are strategically placed between the orifice units. The design includes first nozzle portions of a small diameter to reduce dead space where orifices cannot be placed due to the jackets. The first nozzle portions are eccentrically positioned in opposite directions relative to second nozzle portions of the same diameter as the orifice, effectively minimizing dead space.

Another notable patent is a screen exchanging device. This device includes a cylindrical filter chamber at the distal end of a slide bar, which is axially slidably inserted in a through hole of a housing. The filter chamber has a communicating hole that connects with an inlet in the housing. A concave is formed on the outer peripheral face of the filter chamber, except for the area adjacent to the communicating hole. This concave features multiple fitting holes that extend from the outer peripheral face toward the axis core of the filter chamber, allowing for the insertion of a screen cartridge.
