Latest Patents

One of Tsutsumi's latest inventions is a water jet peening device. This device includes a sealed vessel designed to cover the surface of a welded portion. It operates in a sealed state where the internal pressure is higher than the outside pressure. The device features a jet nozzle that jets high-pressure water to create a cavitation bubble directed toward the surface of the welded portion. Additionally, it has a pressure control hole that allows for the adjustment of the internal pressure within the sealed vessel. This innovative water jet peening device efficiently reforms tensile residual stress on the surface of the welded portion into compressive residual stress.

Another significant patent is related to a wind turbine and its operating method. This invention incorporates a pitch controller, uninterruptible power supply, and rotational speed detector within the rotor of a wind turbine. In the event of a slip ring failure or wire breakage, the pitch controller generates a pitch angle command to control the pitch angle, ensuring the wind turbine operates effectively under various conditions.
