Inventor: OKIMOTO KENICHI
IPC: C21B5/00
Filed: 1987-09-04
Abstract: PURPOSE:To control the gas flow distribution in the in-furnace radial direction of a blast furnace by changing the compounding ratio of a coke layer to be deposited on an ore layer on a belt conveyor at the time of charging raw materials to the blast furnace by a belt type charger. CONSTITUTION:The ore layers 4 and the coke layers 6 are successively deposited and formed on the belt conveyor 3 traveling right under ore tanks 2 and coke tanks 1 and are thereby charged into the blast furnace. The front end of the coke layer 6 is deposited forward of the front end of the ore layer 4 or the ore layer 6 is so deposited that the thickness thereof decreases to a tapered shape furtherer from the blast furnace in the progressing direction at this time, by which the gas flow in the peripheral part in the blast furnace is assisted. The gas flow in the central part of the blast furnace is assisted if the front end of the ore layer 4 is so deposited as to exist forward of the front end of the coke layer or the coke layer 6 is so deposited that the thickness thereof increases to a tapered shape furtherer from the blast furnace in the progressing direction. The blast furnace operation is thereby efficiently carried out and the productivity is improved.

Title: Radio wave transmission bender
Inventor: HONMA SHINICHI
IPC: H01P3/14
Filed: 1993-09-06
Abstract: PURPOSE:To obtain a bender with a low loss acting like a DC circuit breaker and simplifying a connecting work of waveguides by selecting a focal distance and an eccentricity of a reflecting mirror so that the loss of the bender is minimized depending on a distance between a center of an aperture of the waveguide and a center of the reflecting mirror and a diameter of the aperture of the waveguide. CONSTITUTION:A radio wave from an oscillator 3 is sent to a radio wave transmission bender via a waveguide 1. The radio wave radiating from a waveguide 5a is reflected on a reflecting mirror 5c and sent to a waveguide 5b, and sent to a load 4 via a waveguide 2. The loss caused by mismatching of a beam thereat depends on the shape of the reflecting mirror 5c, aperture diameters d1, d2 of waveguides 5a, 5b, and sets of distance s1, s2 between an aperture center of the waveguide 5a, 5c and the reflecting mirror 5c which are uniequivocally depending on that the focal distance of an ellipsoidal face of revolution is decided by the eccentricity and a viewing angle of the reflecting mirror from one focus of the ellipsoidal face of revolution. Thus, the loss is minimized by optimizingly deciding the shape of the reflecting mirror 5c while taking the size of the bent into account.

Filed: 1985-10-04
Abstract: PURPOSE:To detect a voltage drop automatically, by arranging a memory cell containing transistors nonconductive at a low voltage so as to produce such a memory output as to be branched into the head address of a memory address for issuing voltage drop alarm. CONSTITUTION:When the battery voltage VBaT of a battery 12 is lowered and becomes equal to a voltage VALM, P-channel transistors P1-n of a ROM 16 comprising a memory cell of a plurality of thresholds get conductive and the stray capacitances of bit lines B1-n are charged on high levels. When the address line A1 is on a high level, a N-channel transistor N11 becomes conductive and the charge in the bit line B1 is discharged through the transistor N11 to the ground. Since the level of the address line A1 at this time is equal to the voltage VALM, a N-channel transistor N12 gets conductive and does not discharge the charge of a bit line B2. Therefore, the bit lines B1-n for a selected address line A1 are on low level, high level, ..., high level.
