Inventor: INOUE SHOJI
IPC: B23K11/16
Filed: 1991-01-28
Abstract: PURPOSE:To avoid direct contact of an Al or Al-Si plating layer with a welding electrode, to control the consumption of the electrode and to obtain a surface- treated steel sheet capable of being welded to an aluminum-based material by forming a coating layer excellent in electric conductivity. CONSTITUTION:A coating layer 3 consisting of Fe, Ni or their alloy is provided on one of the Al or Al-Si alloy plating layer 2 formed on both sides of a steel sheet 1. The coating layer 3 is made thinner than the plating layer 2.

Abstract: PURPOSE:To manufacture a semiconductor laser which has a simple constitution suitable for a monolithic constitution by growing each layer by alternately supplying atoms or molecules of a III group element and atoms or molecules of a V group element on a stripe structure and using side faces of the grown layers along the stripe as resonant reflecting mirrors. CONSTITUTION:In a GaAs-GaAs double heterostructure laser formed by alternately supplying a III group element and V group element onto a stripe 12 having the shape of an inverted trapezoid after the stripe 12 is formed by etching, an n-GaAs layer 16-1 and n-AlGaAs layer 16-2 have a grown layer 16 composed of a GaAs activated layer 16-2, p-AlGaAs layer 16-4, and p<+>-GaAs layer 16-5. Moreover, an AIGaAs-GaAs quantum well layer can be used instead of the layer 16-3. Since facets 17 which are perpendicular (110) to the plane (100) 13 of the substrate are produced on side faces of the grown layer 16 when such constitution is used, the facets 17 can be used as reflecting mirrors for resonator. Therefore, a laser having a shorter resonator length can be formed easily and, at the same time, the laser can be constituted in a monolithic component.

This induced currents Icu. after reaching peak currents Io, shift to a superconducting filament from the part of copper of the superconducting coil 1 according to shift time constant tau1. And since shifting currents  IF, which finally flow into the superconducting filament of the superconducting coil 1, becomes the function of the shift time constant tau1 and the fall hour t0, if these are selected properly, the values of the permanent currents can be changed optionally.
