Latest Patents

Kou Sato's latest patents include a vacuum pump and a magnetic bearing controller with multiple rigidity modes at high and low gains. This invention utilizes a position deviation calculated by a subtractor of a vacuum pump, which is then input to the PIDs of three modes. The first PID serves as a controller for a high-bias mode, the second for a high-rigidity mode, and the third for a low-rigidity mode. The output signal from the third PID is processed to determine the mean value of a change in indicator current, which is crucial for the system's operation.

Another significant patent is for a vacuum pump and motor controller designed to ensure a safe transition to a regeneration mode while avoiding overvoltage. This system includes a turbo molecular pump with a power supply unit that converts alternating current to direct current. The motor controller is equipped with various circuits to detect power failures and manage the motor's operation effectively.
