Title: Optical communication transmitter
Inventor: TAKENAKA HIROSHI
IPC: H04B10/572
Filed: 1997-08-13
Abstract: PROBLEM TO BE SOLVED: To improve quality in data transmission and to perform an optical communication over a long distance by surely suppressing backscattered light occurring due to stimulated Brillouin scattering with simple constitution. SOLUTION: A transmission data signal Sa is sent out to a light emitting element 21 through a driving circuit 23, a modulation circuit 24 in a control circuit 22, and an optical signal from it is sent out through an optical fiber 27, a circulator 25 and the optical fiber 28. Stokes light (backscattering light) occurring due to the stimulated Brillouin scattering is made incident on a photodetector 26 from the port P2 through the port P3 of the circulator 25, and a detection signal Sb of a level corresponding to its light intensity is outputted to the modulation circuit 24 in the control circuit 22. When the level of the detection signal from the photodetector 26 becomes large, a driving current to the light emitting element 21 is modulated so that the emission spectrum line width of the light emitting element 21 is broadened, and the light emission spectrum line width of the light emitting element 21 is broadened. Thus, the threshold value causing the stimulated Brillouin scattering is set high, and the occurrence amount of the Stokes light is reduced.

Title: Grain-oriented silicon steel sheet extremely low inu core loss and its production
Inventor: KOMATSUBARA MICHIRO
IPC: C21D8/12
Filed: 1997-07-31
Abstract: PROBLEM TO BE SOLVED: To obtain a grain-oriented silicon steel sheet excellent in core loss characteristics, among pits on the surface of a steel sheet caused by crystal orientation emphasizing treatment, by regulating the numeric density of pits of >= a specified depth to <= a specified value. SOLUTION: The crystal orientation emphasizing treatment is the one of corroding the surface of a steel sheet and allowing the specified crystal orientation to selectively emerge, e.g. executing electrolysis in an aq. soln. of NaCl and allowing the (110) crystal plane of the steel sheet to selectively emerge. In this way, the magnetically preferable crystal plane is allowed to emerge on the surface of the steel sheet, by which the magnetic properties of the steel sheet can remarkably be increased. I the case this treatment is executed by a corrosion method, generally, pits are easy to be formed by various defects present in the surface layer of the steel sheet, and, in the case, among the various formed pits, deep ones are present, the effect of the treatment is lessened.  Therefore, it is required that the numeric density of the pits of >=5 μm depth is regulated to <=0.05 pieces/μm<2> .
