Latest Patents

Minoru Soma's latest patents include innovative technologies that utilize electron beams for laminating and shaping materials. The first patent describes a three-dimensional laminating and shaping apparatus that features a column unit designed to output an electron beam and deflect it toward the surface of a powder layer. This apparatus includes an insulating portion to electrically isolate the three-dimensional structure from a ground potential member, an ammeter to measure current flow, and a melting judging unit that detects when the powder layer is melted based on the current value. The deflection controller then uses this information to optimize the electron beam irradiation conditions.

The second patent also focuses on a three-dimensional laminating and shaping apparatus, which includes an electron detector that identifies electrons emitted from the powder layer when irradiated with the electron beam. Similar to the first patent, it features a melting judging unit that generates a melting signal based on the detection strength, allowing the deflection controller to adjust the irradiation conditions accordingly.
