摘要： In order to make the depth of penetration in the weld bead portion uniform and obtain a bead shape having a flat bottom without spiking and meltdown during continuous hot rolling by bonding a plurality of hot-rolled steel materials using a laser beam, the following methods are employed: (A) a method of butt welding wherein center gas is blown against the welding portion symmetrically to the optical axis of the laser beam while side gas is being blown thereagainst from the side, the method comprising conducting welding while the center of laser-induced plasma is shifted in the welding direction from the center of the laser beam by a distance 0.2 to 0.5 times as much as a reference plasma diameter determined from the laser output and the beam diameter, and the type and flow rate of the center gas; or (B) a method comprising scanning the butt line with the laser beam during the laser welding at a speed of 2 to 10 m/min, and simultaneously oscillating the laser beam in the direction vertical to the butt line at a frequency of 40 to 80 Hz at an amplitude of 0.4 to 1.0 mm. Alternatively, (C) in order to prevent formation of blow holes in the weld bead, to make the depth of penetration in the weld bead portion uniform, and to obtain a bead shape having a flat bottom without spiking and excessive penetration, laser welding is conducted while a filler wire of an iron series base material, containing from 0.05 to 3% of one or at least two elements selected from aluminum, silicon, titanium and manganese, is being supplied to the welding portion. Moreover, (D) in order to stably supply a filler wire to the butt portion with high supply accuracy, the filler wire W is passed through a wire supply nozzle having a curved portion, and the filler wire is supplied toward the welding point along the welding line.

摘要： A cooling drum for use in casting a thin cast strip is rotated about its axis while a laser beam having a wavelength of from 0.30 .mu.m to 1.07 .mu.m is irradiated onto a peripheral surface of the drum to form dimple therein. At this time, at least one of the oscillation period of the laser beam, the laser output and the divergence angle of the beam is controlled to assure that each dimple has a depth of no less than 50 .mu.m and a diameter of less than 500 .mu.m and the distance measured between the centers of each adjacent pair of dimples ranges from 1.05 times to 5 times the dimple diameter. At least one of the steps of adjusting the oscillation period of the laser beam and causing the laser beam to scan the peripheral surface of the drum in the axial direction thereof is conducted to cause a irregular deviation of less than 20% in the density of distribution of the thus formed dimples, whereby the formation of waves in the surface of the molten metal placed in contact with the drum during the casting of the thin cast piece is suppressed, to thereby assure a continuous casting of thin cast piece having good surface characteristics and condition.

摘要： A core strip for a honeycomb core panel is composed of a metal strip shaped into a corrugated configuration and having continuous alternate convex and concave portions of identical shape, each of the convex portions being defined by a plateau portion and a pair of inclined portions, and each of the concave portions being defined by a bottom portion and the pair of inclined portions. The inclined portions interconnect the plateau portion and the bottom portion. At the one side edge of the shaped metal strip, the plateau portion and the inclined portions have respective first flanges disposed perpendicular to the metal strip and directed away from a convex surface of the convex portion. At the other side edge of the shaped metal strip, the bottom portion and the inclined portion have respective second flanges disposed perpendicularly to the metal strip and directed away from a convex surface of the concave portion. With this construction of the core strip, the core strips can be welded together with high uniformity and high weldability, and the thickness of the core strip can be greater than that of a conventional one. In the formation of a honeycomb core panel, such core strips can facilitate the bonding between a core and face sheets, and also enable a stable bonding.

摘要： A phase shifting method uses a special interferometer in which the illuminating beam is divided into two or more components and the mask is irradiated from both sides. The pattern to be transferred onto the wafer (the mask) is generated on an optically transmissive substrate by appropriately combining reflective, transparent and absorptive areas. The optical paths of the beams illuminating the back side and the front side of the mask (that will be called transmitted and reflected beams respectively) are chosen so that the phase of the two beams is different by approximately an odd multiple of .pi. radians at the surface of the mask. The combined beams are projected onto the target wafer by suitable optics. The phase difference between the illuminating beams reduces the edge blurring that results from diffraction effects. This steepens the slope of the intensity profile at the edge of the features making it possible to achieve smaller feature sizes in the microlithographic replication without using those phase shifting elements of the conventional phase shifting method which made mask fabrication difficult. As a consequence of the lack of the phase shifting layers, the wavelength range of the method of this invention can easily be extended towards shorter wavelengths, and, further, the new mask is less vulnerable to optical damage. The additional freedom that the phase relation and intensity of the beams can be varied continuously allows for optimization that can lead to improved resolution, compared to conventional phase shifting techniques.
