Title: Purification of alkanesulfonic acid using ozone
Inventor: MAATEIN NOSOUITSUTSU
IPC: C07C309/06
Filed: 1989-09-22
Abstract: PURPOSE: To remove oxidizable org. impurities containing alkylthiolsulfonate without being accompanied by the significant conversion of sulfonic acid to sulfuric acid by bringing alkanesulfonic acid and ozone-containing gas with each other at a specific temp.  
     CONSTITUTION: Alkanesulfonic acid [having formula RSO 3 H (R is 1 20C alkyl)] and ozone-containing gas (containing ozone in a concn. of about 0.001-10 wt.%) are brought into contact with each other at about 20-100°C, pref., 30-about 80°C to remove oxidizable org. impurities containing alkylalkanethiosulfonate.

Title: Semiconductor laser device
Inventor: YAGI TETSUYA
IPC: H01S5/00
Filed: 1986-10-15
Abstract: PURPOSE:To improve the yield of semiconductor laser devices while decreasing a manufacturing cost, by providing a superlattice strain relaxation layer and an Si single crystal epitaxial layer between a contact layer and an electrode in a semiconductor laser chip. CONSTITUTION:In a semiconductor laser chip 10a, a superlattice strain relaxation layer 6 provided between a contact layer 5 and an electrode 8 relieves strain in crystals due to a difference in lattice constant between an Si single crystal epitaxial layer 7 provided on the superlattice strain relaxation layer 6 and the contact layer 5. Moreover, it also improves the crystallinity of the Si single crystal epitaxial layer 7. Further, the Si single crystal epitaxial layer 7 relieves a difference in thermal expansion coefficient between the regions over and under the Si single crystal epitaxial layer 7. Since the superlattice strain relaxation layer 8 and the Si single crystal epitaxial layer 7 function more effectively than conventional submounts, the semiconductor laser device may be assembled by joining the semiconductor laser chip 10a directly to a metallic block 11 without using a submount.
