Filed: 1996-03-25
Abstract: PROBLEM TO BE SOLVED: To obtain a low carbon steel without using a large equipment by using a top-bottom combined blown converter and executing decarburizing terminal in two steps. SOLUTION: In a primary decarburization, the decarburization is executed up to carbon concn. higher by 0.03wt.% to <0.06wt.% than the finish target carbon. and further, in a secondary decarburization, the molten steel is decarburized under pressure in the range of >100Torr to 300Torr to obtain the low carbon steel having 0.02-0.05wt.% carbon concn. and 0.022-0.04wt.% oxygen concn. Since this decarburization, method can be executed ion the smaller molten steel interface area in comparison with the conventional RH and DH, a large diameter vacuum vessel is unnecessary and a compact apparatus can efficiently be used. Further, since the treatment can be executed at a low grade vacuum degree, such as >100torr pressure, a large scale evacuating system is unnecessary.

Title: Constant voltage circuit
Inventor: TAKAI MASAMI
IPC: G05F3/24
Filed: 1988-03-23
Abstract: PURPOSE:To easily perform the control of a temperature characteristic by impressing a prescribed voltage between the drain of one depletion MOS transistor and the sources of remaining two or more MOS transistors at the final stage. CONSTITUTION:Constant voltage output 15 is formed by connecting the source 11 of the MOS transistor 4 to the drain 18 of the MOS transistor 5. The voltage V15 of the constant voltage output goes to (VT5'-VT4') from a voltage VT5' at a point I25 on a characteristic curve 22 and a voltage VT4' at a point I24 on a characteristic curve 21. Here, by setting the inclination of the characteristic curve 21 equal to that of the characteristic curve 22 and setting the temperature characteristic of threshold voltages VT3 and VT5 equal to that of the conductance coefficients of the MOS transistors 4 and 5, it goes to V15=VT5'-VT4'= VT5-VT3. In such a way, it follows that no temperature characteristic is attached on the V15 even when the temperature change is generated in I23. Also, when it is desired to attach the temperature characteristic, it is possible to attach the temperature characteristic of (+) or (-) arbitrarily by providing a difference in the inclination of the characteristic curves 21 and 22.

Title: Semiconductor laser and manufacturing method thereof
Inventor: HOSOBANE HIROYUKI
IPC: H01S5/00
Filed: 1990-03-19
Abstract: PURPOSE:To make it possible to increase the thickness of a current constricting layer comprising a light absorbing layer and an evaporation preventing layer and hence obtain a stable optical output even at a high output by increasing the sum of the thickness of the light absorbing layer and the evaporation preventing layer, which serves as a current blocking layer, to 0.4mum or above. CONSTITUTION:The film thickness of a light absorbing layer 105 is adapted to range from 0.1 to 0.4mum. At the same time, the sum of the thickness of the light absorbing layer 105 and an evaporation preventing layer 106 is arranged to range from 0.4 to 1.5mum. The work to trap electric current in a stripe groove is efficiently carried out by increasing the sum of the light absorbing layer 105 and the vapor preventing layer 106, which serves as a current blocking layer so that a stable semiconductor laser may be obtained even it is oscillated at high output. The formation of a larger stripe groove in a photo etching process where the width of the vapor preventing layer exceeds that of the light absorbing layer 106, is capable of improving more favorably the lamination condition of a second growth layer and increasing a current constricting layer comprising the light absorbing layer 105 and the vapor prevention layer 106 irrespective of an Al composition value of a P type AlGaAs clad layer 104.
