Title: Method for protecting bottom blowing nozzle of converter
Inventor: KUDO ICHIRO
IPC: C21C5/34
Filed: 1988-01-25
Abstract: PURPOSE:To prevent erosion of the inside pipe of the bottom blowing nozzle of a converter and to protect the bottom blowing nozzle by adequately diluting the concn. of the oxidizing gas to be blown from the middle pipe by nitrogen during the time from the start of blowing a carbon material from the inside pipe of the nozzle before stationary blowing. CONSTITUTION:The powdery carbon material is blown together with an inert as from the ribbed 4 inside pipe 1 of the bottom blowing nozzle of a triple pipe type in order to supply a heat source to the converter. The oxidizing gas is blown simultaneously from the middle pipe 3 to burn the above-mentioned carbon material and LPG for cooling is blown from the outside pipe 3. The oxidizing gas to be blown from the middle pipe 3 is diluted by the nitrogen in such a manner that the concn. thereof is kept at <50% the time from the start of blowing of the carbon material from the inside pipe 1 before the stationary blowing. The abnormal temp. fluctuation of the nozzle at this period is thereby suppressed and the erosion of the inside pipe 1 and the ribs 4 is prevented. The life of the nozzle is thereby prolonged and the productivity is stabilized.

IPC: G02F1/025
Filed: 1998-01-28
Abstract: PROBLEM TO BE SOLVED: To reduce the wavelength shift of emitted light without saturating the intensity of the emitted light corresponding to a non-modulating state by reducing the grating constant of a barrier layer rather than a quantum well layer and specifying the difference between the energy level of the valance band peak of the barrier layer and the firs excitation energy level of the valance band of te quantum well layer. SOLUTION: A clad layer 2, multiple well 3 alternately laminating the quantum well layer and the barrier layer, clad layer 4 and contact layer 5 are sequentially stacked on a semiconductor substrate 1. Corresponding to an impression voltage between electrodes 6 and 7, the energy gap of the multiple quantum well 3 is narrowed, an absorption terminal is shifted to a long wavelength, and incident light 9 is modulated. In this case, the grating constant of the barrier layer is reduced rather than the grating constant of the quantum well layer and the difference between the energy level of the valance band peak of the barrier layer and the first excitation energy level of the balance band of the quantum well layer is made larger than 30 meV and smaller than 80 meV.  Thus, a hole in a pair of electron and hole generated by incident light is prevented from being excessively stored in the multiple quantum well.
