Abstract: PROBLEM TO BE SOLVED: To surely discharge a gas evaporating from a surface treatment material and to dispense with a need to specially use a low-melting point material by setting a welded place close to the end edge of a plate material and forcedly spreading the end edge part of the plate material, when fusing from one end of surface treated plate materials laminated in plural sheets and welding the plate materials. SOLUTION: Plate materials 5, 6 as a flange are sandwiched firmly by pressing members 11, 12 and forcedly spread at the end edge part of the plate materials 5, 6 by a spreading member 13, a clearance 14 is formed between both flanges. The flange 6 is elastically deformed by pushing the spread member 13, the other flange remains being straight. The clearance 14 is gradually enlarged, starting at the place of the pressing members 11, 12 down the right. The end edge part 15 of the flange is pushed with the spread member 13 and is protruded over the end edge part 16. The neighborhood of the end edge parts 15, 16 is irradiated with a welding laser beam 9, the place being an appropriate clearance for exhausting the gas evaporating from a surface treating material.

Abstract: PURPOSE:To improve position measurement precision by controlling the output of an antenna which have directivity independently in >=4 directions covering all horizontal directions. CONSTITUTION:An antenna which is so constituted that beams of antennas 1 and 3 are set in the moving direction of a moving body and beams from antennas 2 and 4 are set at right angles to the moving direction is installed on the moving body. Then, RF-IF conversion, frequency reverse spreading, and demodulation are carried out by a GPS receiver 6 by using outputs of the antennas 1-4 and the position and time of the moving body are calculated by a device 7 which calculates the position and moving direction of the moving body. When the position and moving direction of the moving body are known, satellites which can be seen from the moving body and their directions are found by a controller 9 on the basis of information obtained by a GPS satellite track computer 8. For example, when a satellite 31 is seen in the beam direction of the antenna 2, a multipath is reflected by a building and enters the beam of the antenna 4. For the purpose, when an antenna switch 5 is controlled by the controller 9 to acquire a satellite 3, the beam output of the antenna 2 is led out and inputted to a receiver 6. Thus, the signal of the multipath is removed.
