Title: Shigeki Nishina: Innovator in Three-Dimensional Laminating Technology
Introduction
Shigeki Nishina is a prominent inventor based in Miyagi, Japan. He has made significant contributions to the field of three-dimensional laminating and shaping technology. With a total of 16 patents to his name, Nishina continues to push the boundaries of innovation in his industry.
Latest Patents
Nishina's latest patents include a three-dimensional laminating and shaping apparatus and a laminating and shaping method. This apparatus features a column unit that outputs an electron beam and deflects it toward the front surface of a powder layer. It also includes an insulating portion that electrically insulates the three-dimensional structure from a ground potential member. An ammeter measures the current flowing into the ground after passing through the three-dimensional structure. A melting judging unit detects when the powder layer is melted based on the current value measured by the ammeter and generates a melting signal. Additionally, a deflection controller receives this melting signal to determine the conditions for irradiation with the electron beam. Another patent focuses on a similar apparatus that includes an electron detector to detect emitted electrons from the powder layer when irradiated with the electron beam. This system also generates a melting signal based on the detection strength, allowing for precise control of the electron beam irradiation.
