Title: Junji Ishii: Innovator in Gas Turbine Technology
Introduction
Junji Ishii is a prominent inventor based in Kanagawa-ken, Japan. He has made significant contributions to the field of gas turbine technology, holding a total of 8 patents. His innovative approaches have led to advancements in the refurbishment and correction of gas turbine components.
Latest Patents
One of Ishii's latest patents is a method for refurbishing a service-degraded component of a gas turbine. This method allows for the recovery of the microstructure of the alloy in gas turbine components that have deteriorated or been damaged during operation. The process includes a recovery heat treatment, a solution heat treatment, and an aging heat treatment. The recovery heat treatment is performed under a predetermined pressure that exceeds normal pressure, raising the component's temperature to a specific level. Following this, the solution and aging heat treatments are conducted under reduced pressure or an inert gas atmosphere.
Another notable patent is the apparatus and method for correcting deformation of a gas turbine blade. This apparatus features a stationary die that holds the back surface of the blade's tip shroud and a pressing die that applies pressure to the front surface. A hydraulic drive mechanism, including a pressure generator, is utilized to press the pressing die against the tip shroud, while a control device manages the driving conditions based on pre-stored deformation correction data.
