20120145683 | LASER PROCESSING SYSTEM AND OVERLAY WELDING METHOD - A laser processing system includes a laser processing head, a powder supply device, and a controller. The powder supply device supplies powder to the laser processing head. The laser processing head includes: a laser emission unit which irradiates a workpiece with laser light; and a powder supply unit which receives the powder supplied from a powder supply device to the laser processing head, and can supply the powder to a laser spot on the workpiece. The powder supply unit includes: a powder discharge unit which can discharge the powder toward the laser spot on the workpiece; and a powder-supply control mechanism which controls the amount of the powder to be supplied to the powder discharge unit, by distributing to the powder discharge unit at least a part of a flow of the powder supplied from the powder supply device. The controller controls the distributing by the powder-supply control mechanism. | 06-14-2012 |
20120243653 | CONTROL ROD FOR BOILING WATER REACTOR AND METHOD OF MANUFACTURING CONTROL ROD - A control rod has four blades, each of which has a rectangular cross section in a plane perpendicular to an axis of the control rod, disposed so as to form a cross-shaped cross section in the plane perpendicular to the axis. The blades include a plurality of aligned square tubes having a square cross section in a plane perpendicular to the axis and including a neutron absorber filling hole filled with neutron absorber, frame plates disposed parallel to the aligned square tubes in a direction perpendicular to a width direction of the blade, and on one side end and another side end of the blade in the width direction, respectively, and cover plates disposed along the width direction and sandwiching the aligned square tubes. Each blade has the aligned square tubes, the frame plates and the cover plates joined together as a single-piece construction by Hot Isostatic Pressing diffusion bonding. | 09-27-2012 |

20080237195 | WELDING SLOT SEALING STRUCTURE AND WELDING METHOD - Blades are connected to the surface of a disk and slots are formed in the surface of a shroud, which is opposite from the other surface of the shroud where the blades are to be welded. The blades are arranged on the opposite surface from the slots and a laser beam is applied from the surface in which the slots are formed, to weld the shroud and the blades. If powder is melted and put in the slots formed for welding in the shroud to fill the slots, thermal distortion occurs. On the other hand, if the slots are left empty, a problem of degrading the fluid performance arises. To solve these problems, components are installed on the surfaces of the slots on the opposite side from the blades after the blades and the shroud in which the slots are formed are welded. Alternatively, the slots are filled with a material different from that of the shroud, such as a resin. With this configuration, distortion caused by welding heat can be reduced without degrading the fluid performance. This method can be applied to the case where the blades are formed on the surface of the shroud, not on the surface of the disk, and to the slots formed in the disk after the blades and the disk are laser-welded. | 10-02-2008 |
