Patents by Inventor Hironari Mikata

Hironari Mikata has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 7968816
    Abstract: A weld fairing apparatus and a welding method using the apparatus effectively prevent a weld metal zone from forming a humping bead. The welding method includes: butting first and second object pieces together; heating the butted first and second object pieces using a heating device, thus forming a weld metal zone; and placing a fairing device such that the fairing device comes into contact with the weld metal zone and fairs the weld metal zone.
    Type: Grant

  • Publication number: 20100200554
    Abstract: Welding equipment includes a torch for irradiating a laser beam, wire feeding means for feeding a filler wire, and tracking means for controlling the moving tracks of the torch and the wire feeding means so as to make the moving tracks follow a welding line. The tracking means has a contactor provided so as to be advanceable/retractable for making contact with a joint object resiliently. The torch and the wire feeding means are moved so as to follow the welding line by touching the contactor of the tracking means resiliently to the joint object while feeding the filler wire to a welding portion and irradiating that portion with the laser beam, thereby joining the joint objects.

  • Patent number: 7608799
    Abstract: A solid-state laser processing apparatus includes a solid-state laser oscillator, a laser beam diameter controller, an optical fiber, and a processing head. The solid-state laser oscillator oscillates a laser beam. The laser beam diameter controller controls a beam diameter of the laser beam, and includes an aperture. The aperture controls a beam quality of the laser beam defined by M2 so as to fall in a range of 85?M2?105. The optical fiber guides the controlled laser beam therein. The processing head includes a transfer optical system, and irradiates the guided laser beam to a surface of a workpiece to be processed by way of the transfer optical system.

  • Patent number: 7560661
    Abstract: A laser beam machine for processing an article to be processed with a laser beam from a processing scanner 1 comprised of an optical system employing a laser oscillator 10. Article position controllers 2a and 2b are controlled in a coordinated manner in accordance with the direction of the laser beam from said processing scanner 1 such that the position of a surface to be processed of the article is controlled to be nearly perpendicular to the direction of the laser beam from the processing scanner 1. While an article to be processed mounted on one article position controller 2a is being processed and unloaded, another article to be processed can be loaded onto the other article position controller 2b. Thus, the wait time for the laser beam machine can be reduced and production efficiency can be improved.
