Title: Production of low manganese alloy
Inventor: OGISO YUZO
IPC: C22C1/02
Filed: 1997-06-27
Abstract: PROBLEM TO BE SOLVED: To promote the vaporization of manganese from an alloy and to mass-produce a desired low manganese alloy by using a VOD furnace and adjusting the temp. of molten alloy and the vacuum degree in a furnace to suitable conditions after executing oxygen blowing to the molten low manganese alloy with adjusted C content. SOLUTION: A molten alloy containing manganese of about 0.12-0.15 wt.% obtd. by melting with an electric furnace or a converter, is treated by using a VOD furnace. After adjusting the carbon content in the molten alloy in the range of 0.01-0.05%, oxygen is blown. Successively, the temp. of the molten alloy is adjusted in the range of 1650-1750 deg.C and the vacuum treatment is executed by adjusting the vacuum degree in the furnace to <=1.0 Torr to promote vaporization of the manganese from the alloy. By this method, the low manganese alloy having <=0.1 manganese content is obtd. It is sufficient that the oxygen blowing is executed before degassing in the furnace and it is not necessary to execute this blowing in the vacuum.

Title: Polarization maintaining optical fiber
Inventor: TANAKA SHIGERU
IPC: G02B6/02
Filed: 1988-07-12
Abstract: PURPOSE:To easily obtain a core which as large ellipticity by forming a single waveguide part of cores which are arranged in a clad and have a larger refracting index than the clad. CONSTITUTION:The single waveguide part consists of the cores 11 and 12 which are arranged in the core 13 and have the larger refractive index than the clad 13. The waveguide part (x) is high in refractive index on an average in (x)- polarization mode and low in mean refractive index in (y)-polarization mode. Consequently, the refractive indexes corresponding to both polarized components are different to cause double refraction. Namely, the (x)-directional propagation constant betax is not equal to the (y-directional propagation constant betay and the components in both polarization modes can not be coupled and are propagated without interfering with each other. Consequently, an optical fiber corresponding to an elliptic core type polarization maintaining fiber which has large ellipticity can easily be obtained.
