Title: Gallium-nitride-based semiconductor luminous element
Inventor: NISHIZUKA MITSURU
IPC: H01S5/00
Filed: 1999-05-21
Abstract: PROBLEM TO BE SOLVED: To suppress the leakage of high-order mode light to an underlying layer across a cladding layer by setting n- and p-type cladding layers and a waveguide to a first three-layer waveguide, and by setting a substrate, the underlying layer, and the n-type cladding layer to a second three-layer waveguide. SOLUTION: To prevent a high-order mode light from leaking to the underlying layer 2 across an n-type cladding layer 3, the normalized frequency of a second three-layer waveguide is set to be different from values 25 to 29, and a mode field is set to be different from a first three-layer waveguide. Therefore, the first three-layer waveguide comprises the n-type cladding layer 3, a waveguide layer, and a p-type cladding layer 7; and the second three-layer waveguide comprises a sapphire substrate 1, the underlying layer 2, and the n-type cladding layer 3.  Consequently, as the equivalent refractive index of the waveguide mode of the first three-layer waveguide is different from that of the waveguide mode of the second three-layer waveguide, the leakage of the high-order mode light generated at an active layer is suppressed to leak to the underlying layer 2 across the cladding layer 3 by mode connection.

Abstract: PURPOSE: To make possible the accurate arc welding to be carried out, by automatically correcting the difference between the detected data for weld line and the weld-line-data memorized in the torch traveler, and also, by making automatically removable the detector while the welding work.  
     CONSTITUTION: When the contact 31 passes over the end of the parent metal 60, the contact is broken and the robot is stopped. This stip point is memorized in the coordinate data memory 80, and the computing unit 81 computes the data for a position upside by the tip radius R of the contact 31 from the stop point, on purpose to obtain the starting point of the weld line. The end point Pn of welding is computed from the memorized point P 1  and the welding point l n  memorized in the weld- line-length-instructing-data-memory 72. Then, the welding instruction is compiled from this starting point of weld line and control instruction memorized in the welding-sequence-program-memory 73, and the result is memorized in the welding- program-memory 82. After these procedures are repeated for all weld lines, the welding detector 24 is removed from the clamp. Hereby, the difference between the actual weld line and the instructed weld line can be automatically corrected, so that the arc welding can be carried out accurately.
