IPC: B23K20/04
Filed: 1987-10-15
Abstract: PURPOSE:To obtain clad material excellent in adhesive property and shape stability by heating and reducing Cu and a Cu alloy in the specific temperature range to activate the surfaces and performing annealing treatment thereon at the same time and cooling these below the specific temperature to roll and weld these with pressure on the same line. CONSTITUTION:Coiled bar stocks 1 and 1' are passed through a cooling chamber 3 via a reducing furnace 2 and rolled by rolling rolls 4 and 4' and formed to a composite metal bar 10 and wound by a coiler 5. With the reducing furnace 2, the bar stocks are subjected to surface reducing treatment in the temperature range of 500-1040 deg.C and while the surfaces are reduced and activated, annealing is also performed thereon. An atmosphere in the reducing furnace is desired to be reduced by high-temperature H gas G. After the heating and reducing treatment is carried out, the bar-stocks are passed through the cooling chamber 3 and cooled to <=100 deg.C and rolled and welded with pressure by the rolling rolls 4 and 4' and wound by the winder 5. By this method, the annealing treatment can be carried out simultaneously with reducing and since the bar stocks are immediately subjected to rolling and welding with pressure, stable and firm adhesion is obtained and a flat plate-shape can be easily obtained.

Abstract: PURPOSE:To facilitate the adjusting work of a track zero position with high accuracy by providing an inclined part on a light shielding plate and constituting a photoelectric senser and a detected part movably in the relative up-and-down direction (Z axis direction). CONSTITUTION:When the track zero position of a magnetic head is adjusted, first of all, a carriage assembly 12 is moved to a position equivalent to the track zero position of the X axis direction, i.e., the forwards and backwards directions. Then, a displacement member 24 arranged in the direction perpendicular to the X axis direction and in the horizontal direction (Y axis direction) is adjusted by a adjusting screw 42 and a track zero senser 28 and the light shield plate 36 are moved to a Z axis direction relatively. Since the plate 36 has a slope part 36a as the inclined part, by the relative movement of the Z axis direction, a position where the optical path of the senser 28 becomes from a transmission state to a cut off state or becomes to the inverse state is present. At the point changing like this, the screw 42 is fixed. Thus, the size of the depth direction of entire device is reduced and the adjusting work is performed simply and surely.
