Latest Patents

One of his latest patents is a method of controlling a gate valve. This invention focuses on suppressing particle scattering by controlling the gate valve's opening in relation to the internal pressure of the chamber and atmospheric pressure. The method involves detecting the torque of a motor that drives the valve body, acquiring a local maximum of the torque during decompression, and ensuring that the valve body opens only when the torque exceeds this local maximum. This careful control allows for the effective discharge of particles along with gas from the chamber.

Another significant patent is for a method for sterilizing a centrifugal separator. This invention includes a sample line and a rotating apparatus with a rotor that separates samples by centrifugal force. The centrifugal separator is equipped with a sterilizing apparatus that ensures the sample remains uncontaminated by allowing a sterilizing fluid to flow through the sample line. This innovation is crucial for maintaining the integrity of samples in various applications.
