Latest Patents

One of Shirai's latest patents is a method and device for manufacturing a member having a through hole. This innovative method includes several steps: a primary formation step, an intensity determination step, a laser modulation step, and a secondary formation step. The primary formation step involves radiating a laser beam to a workpiece member to create a pilot hole with a smaller inner diameter than the through hole. The intensity determination step assesses whether the light intensity is equal to or less than a predetermined threshold value. The laser modulation step adjusts the spatial light phase of the laser beam when the light intensity meets the threshold. Finally, the secondary formation step uses the modulated laser beam to create the through hole.

Another notable patent is for arc welding equipment designed to join objects at high speed while minimizing strain after joining. This equipment features a nozzle that houses an electrode forming arc plasma, which is constructed from a gas supply part and a gas suction part. The gas supply part has holes that supply gas outward in a radial direction of the arc plasma, while the gas suction part removes the gas. This innovative design allows for efficient welding by compressing the arc plasma and extending its length.
