Title: Slopping detector for converter
Inventor: UEDA YUUJIROU
IPC: G01J5/00
Filed: 1984-04-27
Abstract: PURPOSE:To enable a higher operation rate with the detection of slopping in a converter by a method wherein a photoconductive detector is provided in a through hole on the side wall of a converter and receives light in the converter to be divided into a plurality of wavelength areas preset and then, the area of the wavelength areas devided is computed. CONSTITUTION:Oxygen is blown into molten iron 17 and a slag 16 in a converter 1 from a lance 19 to extract phosphor and sulfur with agitation. A photo detector 6 is inserted into a through hole 4 on the side wall of the converter and converts light in the converter into an electrical signal with photoelectric conversion element 10. Then, the light in the converter is divided into wavelength areas, for example blue, green and yellow with a divider 11 and the areas of each color area is computed 12 and compared with the reference for deciding on the slopping to judge 13 the slopping. Then, as the slopping begins, yellow based color grows and the long wavelength area increases. The division of the light in the converter into wavelength areas facilitates the detection of slopping and elevates the operation rate with an effective inhibision thereof.

Abstract: PURPOSE: To obtain a solar light condenser of high accuracy by laying thin Fresnel sheets along the envelope curved surface composed of net-, grid- or lattice-shaped fine wire material groups thereby forming the Fresnel condenser and supporting the thin Fresnel sheets in a strain-free manner.  
     CONSTITUTION: The supporting frame 15 of the Fresnel condenser is made by welding straight frames 151, 152, 153, 154 of the surroundings arch frames 155, 156, and stanchions 18. Studs with heads 161, 162 are studded at predetermined intervals on  the top surface of the frames 152, 154, 155, 156, and piano wire groups 171, 172...  181, 182... having been coated with resin are spanned between these. These piano  wires are extended in a grid or lattice shape to form the cylindrical envelope curved  face of the curvature conforming to the design of the Fresnel condenser. Such a  smooth envelope curved surface makes the slip movement at the thermal elongating  or contracting easy; therefore, the accuracy of condensing may be maintained high without producing any strain and deformation in the thin Fresnel sheets.

IPC: C01G28/02
Filed: 1982-05-21
Abstract: PURPOSE:As2S3 is added to the sulfuric acid extract from decopperization slime and aeration is effected under heating, the precipitate formed is separated, SO2 gas is blown into the aqueous solution to effect the reduction of arsenic, then cooled to separate arsenic from the mother liquor, thus recovering high-purity arsenous acid. CONSTITUTION:Decopperization slime is treated with an aqueous sulfuric acid and the insoluble residue is separated. The resultant extract is combined with arsenic sulfide and aerated under heating. The copper and almost of antimony which have dissolved in the extract cause precipitation, meanwhile almost of pentavalent arsenic remains dissolved in the extract. After separation of the precipitate, SO2 gas is blown into the mother liquor to reduce arsenic to recover good-quality arsenous acid. Since almost of copper and antimony is separated through simple operations, high-purity arsenous acid is recovered and the mother liquor after the recovery can be used as an extractant for decopperization slime.

IPC: H02K3/34
Filed: 1999-03-29
Abstract: PROBLEM TO BE SOLVED: To maintain coil insulation by preventing generation of air gaps in cured impregnated resin in the periphery of each strand insulated wire, concerning a strand coil of a high voltage rotating machine stator. SOLUTION: In lamination material 7 of a strand coil 2 constituting a stator coil, a prepreg layer 7a and a prepreg layer 7b are formed as a plurality of prepreg layers which have adjustable resin melting temperatures and are different in melting temperature. A base material layer 7c is made a center, and the prepreg layers 7b and 7a are arranged in this order toward both outsides in such a manner that the resin melting temperature becomes high. By this constitution, rapid curing of melted resin is made unnecessary by fluidity adjustment of the melted resin and the more accurate estimation of the diffused state, when the strand coil is pressure-molded at a high temperature, so that generation of air gaps due to foaming which is to be caused by rapid curing reaction can be prevented.
