Latest Patents

One of Tanaka's latest patents is the "Flocculation Basin in Water Treatment Process." This invention optimizes the fluidizing speed of water within a flocculation basin by adjusting it according to the state of flocculation. The state is determined by capturing multiple images over a set period using an ITV positioned inside the basin. By recognizing a substantial number of flocs from these images, the system calculates the particle diameters and determines the particle diameter distribution, which is then used to adjust the water fluidizing speed accordingly.

Another notable patent is the "Weld Detector." This device is designed to inspect welded steel pipes by subjecting them to a static magnetic field created by a sensor. The sensor consists of an electromagnet and a transmission and reception coil. The electromagnet is powered by a DC supply, while the transmission coil receives pulse currents at specific intervals. As the coil generates transverse ultrasonic waves in the steel pipe, these waves propagate through the pipe and are reflected back, allowing the system to detect the weld's position based on the amplitude of the received signals.
