Teruhiko Yajima 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: 12000695
    Abstract: An electrode-misalignment detection device in a resistance welder that joins members together by holding them between opposing electrodes and applying pressure and electricity thereto includes an electrode misalignment detector that simultaneously approaches outer peripheries of both electrodes to detect misalignment thereof. The electrode misalignment detector includes a clamping member, a signal generator, a non-closed-state detector, and a misalignment determiner. The clamping member is movable toward the electrodes to clamp them from opposite radially outer sides and is settable in a predetermined closed state when the electrodes are located at appropriate positions. The signal generator outputs a movement state signal according to a movement state of the clamping member. The non-closed-state detector detects that the clamping member is in a state other than the predetermined closed state based on the movement state signal.

  • Patent number: 9776286
    Abstract: In a method of manufacturing a vehicle body a side structure and a center structure are positioned in place using a fixture or the like, and fixed by welding with maintained accuracy of mounting positions; annular parts along the width of the cabin of the vehicle and other parts are temporarily mounted to be retained without being welded; additional welding is performed on the center structure and the side structure, and the annular parts along the width of the cabin of the vehicle and other parts are positioned in place using a fixture or the like, and are fixed by welding with maintained accuracy of mounting positions; additional welding is performed on the parts; and a roof complex is mounted and fixed by welding with maintained accuracy of mounting positions.

  • Patent number: 6666631
    Abstract: In the electrode tip dressing apparatus, the upper surface and the lower surface of a dressing body is covered with an upper chip capturing case and a lower chip capturing case so that the chips generated when electrode tips are dressed by polishing or grinding are prevented from scattering to the outside, whereby a chip collection efficiency can be increased.
