Title: Reduction of iron ore
Inventor: ENRIKE RAMAN MARUTEINESU BERA
IPC: C21B13/02
Filed: 1984-05-16
Abstract: A method for the gaseous reduction of iron ore to sponge iron in a vertical shaft moving bed reactor (10) wherein a hot gaseous mixture of hydrogen and a carbon monoxide is used to reduce the ore. It has been found unnecessary to use the external catalytic reformer of prior art processes to reform the methane and other hydrocarbon constituents of the natural gas commonly used as a source of gaseous reductants. By establishing a reducing gas recycle loop to which make-up natural gas and steam are fed in the proper proportions, the product sponge iron in the reactor (10) can be used to catalyze hydrocarbon reformation, provided that the carbon content of the recycled gas is maintained low by removing carbon dioxide therefrom. When pure methane is employed, steam/methane molar ratios within the preferred range of 1,4 : 1 to 2.2 : 1 are used.

Title: Encoder
Inventor: TANITSU OSAMU
IPC: G01D5/38
Filed: 1990-04-13
Abstract: PURPOSE:To detect the quantity of relative movement between a lighting system and a photodetection system in the pitch direction of a reflection scale by providing the photodetection system for diffracted light from the reflection scale which has a reflection type diffracting grating provided at the convergence position of the objective of the lighting system. CONSTITUTION:The reflection scale 6 where the diffraction grating 6A which has a specific periodic pitch P is formed is provided at the focus position of the objective 5. The diffraction grating 6A diffracts this incident light to project light L(0) of 0th order at a projection angle theta0 and light L(m) of m-th order for detection at a projection angle thetam. The L(m) is converged by the objective 5 and projected in the direction Ax of the optical axis. When the wavelength of illumination light varies by DELTAlambda owing to temperature variation, the diffraction angle thetam varies by DELTAthetam from sintheta6-sinthetam=mlambda/P, but the diffraction point is on the focus surface of the objective 5, so the projection light L(m) of the objective 5 is only shifted laterally to L'(m), so that the light is projected in the optical axis direction Ax at all times. Consequently, variation in the diffraction angle due to the wavelength variation of the illumination light can be corrected.
