Title: Ren Morinaka: Innovator in Laser Technology
Introduction
Ren Morinaka is a prominent inventor based in Hitachi, Japan. He has made significant contributions to the field of laser technology, holding a total of 16 patents. His innovative work focuses on enhancing the efficiency and effectiveness of laser applications in various industries.
Latest Patents
Among his latest patents are a laser welding apparatus, a preventive maintenance method for the internal reactor of a nuclear power plant, and a laser cutting apparatus. The laser welding apparatus features a welding head and a welding head scanning apparatus. It includes a collimate lens installed on the head body, which is positioned opposite the end face of optical fibers. This design allows for a shortened length of the welding head, improving its functionality. A laser generated by a laser oscillator is introduced into the optical fiber, passes through the collimate lens, and is converted into a parallel beam. This parallel beam is then irradiated onto the surface of the welding portion, melting it for effective welding. Additionally, metallic powder is jetted from powder feed paths in the head body to perform build-up welding on the melted surface.
Another innovative method developed by Morinaka involves shot peening. This method utilizes a chamber equipped with a water jet generation apparatus and a mesh. The chamber is pushed against the surface of a peening object, and a rotary vane generates a water jet that flows toward the peening object. Shots are propelled along with the water jet, colliding with the surface and imparting compression residual stress. This process effectively prevents the spread of contaminants from the peening object.
