摘要： PROBLEM TO BE SOLVED: To provide a steel belt jointing method which is advantageous in welding quality and productivity when three different kinds of steel belts are jointed to manufacture a steel belt used for a tailored blank method. SOLUTION: In this jointing method, when edge parts of three different steel belts 1, 2, and 3 are continuously welded, laser welding is performed while a width directional force is applied to the steel belts by passing the steel belts 1 and 2 between a welding roll and plural inclined presser rolls so as to work a pressurizing force on edge part ends of the steel belts 1 and 2. Then, laser welding is performed while a width directional force is applied to the steel belts by passing the welded steel belts 1 and, 2, and the steel belt 3 between the welding roll and the plural inclined presser rolls so as to work a pressurizing force on edge part ends of the steel belts 1, 2, and 3.

摘要： PROBLEM TO BE SOLVED: To provide a steel belt jointing method which is advantageous in welding quality and productivity when three different kinds of steel belts are jointed to manufacture a steel belt used for a tailored blank method. SOLUTION: In this jointing method, when edge parts of three different steel belts 1, 2, and 3 are continuously welded, a welding roll 7 and a presser roll 5 of a center steel belt 2 are arranged in a direction perpendicular to the proceeding direction and presser rolls 4 and 6 of both side steel belts 1 and 3 are passed between plural presser rolls inclined. Laser welding is performed to three steel belts while a width direction force is applied to the steel belts on both sides by inclining the presser rolls, so that a pressurizing force is worked on an edge part end between the steel belts 1 and 3 of both sides.

摘要： PURPOSE:To form plural patterns having a deformed shape on a roll surface with single light source by juxtaposing a spectroscope for patterning on the laser beam incident side of a condenser lens. CONSTITUTION:The laser beam 19 emitted from a laser transmitter 13 is magnified by a beam expander 14 and arrives at a patterning device 18. The laser beam is spectrally split to plural beams by the device 18 to be desired patterns and by focusing to a worked object 1 with a condenser lens 17 the irradiation working is performed. The rugged patterns to be worked and formed are determined by the wavelength of the laser beam and the number and sizes of the meshes to be split in the case of suing a diffraction grating. The size and arrangement of a through-holes 22 to be penetrated are selected in the case of using a filter for forming the patterns.

摘要： PURPOSE:To efficiently wash a magnetic filter by the action of both the generated centrifugal force and an alternating magnetic field by arranging the magnets in such a form that the magnetic filter is pinched thereby from the upper and lower parts and rotating the magnetic filter while fixing the magnets. CONSTITUTION:When a magnetic filter is washed, the magnetic filter 2 is rotated at high velocity with a motor 11 and washed by both an alternating magnetic field which is generated by rotation and allowed to act on the filter element and magnetic particles and washing liquid continuously and intermittently ejected through the nozzles 13. In this case, when both a ferromagnetic fine wire constituting the filter element and the magnetic particles to be attracted and removed have the same magnetic characteristics, demagnetizing effect due to the alternating magnetic field is caused and when the magnetic characteristics of both are different to each other, magnetic-pole inversion effect due to the alternating magnetic field is caused and thereby washing efficiency is improved. Simultaneously the channel flow in the filter is prevented by intermittent injection of washing liquid.
