Title: Controlling method for wall thickness in mandrel mill
Inventor: MIYASHITA MAKOTO
IPC: B21B17/04
Filed: 1981-09-24
Abstract: PURPOSE:To accurately control the wall thickness of a material with a relatively simple method, by controlling the relative speed of the speed of a mandrel and the rolling speed of a pipe-shaped material, and changing the rolling speed, in rolling the material. CONSTITUTION:A mandrel bar 2 is inserted to the inside of a pipe-shaped material 1, which is rolled through plural rolling stands equipped with grooved rolls 3. In this case, the wall thickness of the material 1 is controlled while controlling the relative speed of the speed of a mandrel bar 2 and a rolling speed of the material 1 in rolling. The controlling of the relative speed of the material 1 and the mandrel bar 2, that is in other words, the controlling of rolling load is made possible by the number of revolutions of the roll and a moving speed of the bar 2. Accordingly the change of rolling load is related to the value of a mill rigidity, and then the wall thickness is controlled because the change of the  wall thickness depends on the mill rigidity. Further, the speed of the material 1  is calculated from the relation between the peripheral speed of the roll and a forward slip, on the other hand, the speed of the material 2 is easily measured from a driving shaft because the bar 2 moves at a constant speed.

Title: Semiconductor light-emitting device and manufacture thereof
Inventor: KUNO MASAAKI
IPC: H01S5/00
Filed: 1985-07-10
Abstract: PURPOSE:To integrate a laser having different oscillation wavelengths easily, and to manufacture a semiconductor light-emitting device by forming a mesa by etching a semiconductor substrate and growing active layers having different thickness to a flat section and an inclined section in the mesa through one-time MBE. CONSTITUTION:A GaAs substrate 1 is mesa-etched to shape a mesa 1A. The mesa angle theta1 of the mesa 1A is brought to 45 deg. at that time. A GaAs layer 2 is grown on the whole surface by applying a MBE method. When the thickness of the GaAs layer 2 in a flat section in the mesa 1A is represented by t1 and that in an inclined section by t2 at that time, the relationship of t2=0.7t1 t1 COS45 deg. holds. Consequently, when the MBE method is applied to the GaAs substrate 1 with the mesa 1A and the GaAs layer 2 is grown, the flat section in the mesa 1A is thickened, and the inclined section is thinned. Accordingly, when active layers having quantum well structure in quantum well type lasers are formed by the principle, a plurality of the quantum well type lasers having different oscillation wavelengths can be integrated on the same substrate and shaped simultaneously.

Abstract: PURPOSE:To reduce a slide moving resistance applied to the needles by a coincidence of the section between a tip of a needle connected to a driving section and a bending point to the printing direction axis. CONSTITUTION:The rear ends of a plural of needles being bended at right angles on the prescribed bending point 21 become to the connecting sections 22, the longitudinal section of the needle 20 is disposed in the guide section 12 keeping a straight line shape, and the connecting section 22 is fixed to the movable end 24 which is the tip of the armature 16 in the driving section 11.

The irradiation is executed by setting the processing speed of the laser marking device at 100 mm/sec and scanning the device. The resin film of the irradiated area is dehydration-carbonized and changed black by heat when the irradiation is executed. The resin film layer does not peel under the above-mentioned irradiation conditions.
