IPC: H01F30/12
Filed: 1984-07-31
Abstract: PURPOSE:To reduce the exciting current of a three-phase U-shaped butted type core by a method wherein the constitution of the core is simplified by butted-concentration of both ends of three pieces of the double laminated cores, which are deformed into a U shape and are performed a thermal treatment, and a heat-resisting insulating film, on both faces of which a magnetic fluid is bonded, is inserted in the butted parts. CONSTITUTION:Two pieces of big and small ring-shaped cores, on each of which an oriented silicon steel strip is wound around helically and concentraically, are presse from three directions on the outside and U-shaped core legs 1, 1' and 1'' are made by performing a thermal treatment on the cores. At this time, gaps C and D are generated between both ends of the interior of an outside core A and both ends of an inside core B. The core legs 1 and 1'' are placed in parallel to each othr, the core leg 1' is placed between the core legs 1 and 1'' in the reverse direction to that of the core legs 1 and 1'', a bolt is penetratingly inserted in the gaps C and D, and the outside and inside cores A and B are integrally formed in one body. According to this constitution, the magnetic characteristics of the three-phase U-shaped butted type core can be improved by setting the butted areas at the prescribed value, because the magnetic path length of each core leg becomes equal and the ratio of the core width of each phase to the winding thickness becomes 1:1.6 (rectangular section), and an assembling of the core is also simplified. Moreover, the butted parts are lessened, no-load current is reduced and the exciting current of the core is also reduced as a heat-resisting insulating film, on both faces of which a magnetic fluid is bonded, is inserted in the butted parts.

Title: Method for decomposing hydrocarbon halide solvent
Inventor: KONDO TOSHIHITO
IPC: C02F1/58
Filed: 1992-05-29
Abstract: PURPOSE:To clean water to be treated without freshly contaminating the water with another org. matter by disposing the water contaminated with a hydrocarbon halide solvent so as to face an anaerobic microorganismic culture liquid via a hydrocarbon halide permeable membrane. CONSTITUTION:A hydrocarbon halide-permeable silicone rubber pipe 5 is fixed by disposing this pipe zigzag in the anaerobic microorganismic culture liquid 9 in a culture chamber 1. The liquid is kept stirred during waste water treatment so that the liquid 9 near the surface of the silicone rubber pipe 5 is refreshed at all times. The water to be treated is forcibly fed from a supply port 6 by a pump 7 and the treated water is discharged from a discharge port 8. The hydrocarbon halide solvent in the water to be treated, then, penetrates the surface of the long silicone rubber pipe 5 during the passage through the inside thereof and comes into contact with the culture liquid 9 thereon. The water is thus subjected to the decomposition by anaerobic microorganisms. The org. matter in the liquid 9 does not permeate the silicone rubber pipe 5 and, therefore, the contamination of the water to be treated with this org. matter does not arise.
