Title: Control system of reactive power compensating device
Inventor: HONMA TADASHI
IPC: G05F1/70
Filed: 1980-07-22
Abstract: PURPOSE:To apparently increase the capacity of a reactive power compensating device, by smoothing an output of the reactive power detector of a load, outputting it through limiting circuit, and controlling the reactive power cmpensating device. CONSTITUTION:A reactive power detector 21 is a detector which answers at a high speed, and detects the reactive power at every semicycle. Its output qF is a signal corresponding to magnitude of the reactive power which is generated by an arc furnace, and corresponds to a difference between a signal qC corresponding to magnitude of reactive power of a phase advance capacitor 4, and reactive power qL which is generated by a reactor 32 of a reactive power compensating device. In this case, an output qFB of a filtering circuit 211 is made to pass through a limiting circuit 212, and an output q'FB is outputted, but when an output of the circuit 211 is smaller than qFB1, q'FB becomes zero, a base portion qFB2-qFB1 is outputted as q'FB between qFB1-qFB2, and when it exceeds qFB2, a constant value of qFB2-qFB1 is outputted as q'FB. Accordingly, a value of qFB2-qFB1 is taken large within a range where a range where power-factor of a system does not become lower than its normal value.

Title: Power feed switching device
Inventor: AOKI EIJI
IPC: H01H63/02
Filed: 1990-04-18
Abstract: PURPOSE:To make an independent connection easy even if there are three or more feed lines by connecting moving contacts of three or more feed lines via central contacts and further providing drive circuits individually for each feed line. CONSTITUTION:Moving contacts 1b, 5b and 9b of relays 2, 6 and 10 are connected to central contacts 1c, 5c and 9c of respective relays and grounded when the drive circuits of the relays 2, 6 and 10 are not in operation. For example when feed lines 2 and 6 are to be connected to each other, connecting signals are given to control lines 3 and 4 and further 7 and 8 and drive circuits 1d and 5b are driven. By this drive, moving contacts 1b and 5b operate to be connected to the central contact 13 and the feed lines 2 and 6 are connected to each other via contact 13. In this way the connection becomes easy by combining the three feed lines 2, 6 and 10, and even if there are three or more feed lines, by separating and controlling the feed lines.

Title: Method and apparatus for automatically measuring fluid
Inventor: HOSHI TAKEO
IPC: G01D3/028
Filed: 1987-04-23
Abstract: PURPOSE:To perform accurate, quick measuring work, in an automatic measuring apparatus, in which the fluctuating component in the detected weight signal is removed by using LPFs, by selecting the optimum LPF corresponding to the supplied weight of fluid. CONSTITUTION:Fluid, which is material to be measured, is supplied to a measuring body 3 having transducers 5 from a hopper 1. The measured value is inputted into CPU 13 by way of LPFs 9-11. The CPU 13 controls a valve 2 of the hopper 1 and gradually decreases the supply of the fluid per unit time. The CPU 13 controls a switching device 8 so that the LPFs 9-11 having the optimum filter characteristics are used in correspondence with the feeding amount of the fluid in each stage. In this method, the fluctuating component in the detected weight signal based on the vibration and the like in a mechanical system yielded during the time of measurement can be removed optimally in correspondence with the moving amount of the fluid. Therefore, the measuring work can be performed quickly and accurately.

SOLUTION: In the refining method of the chromium-containing molten steel, composed of a decarburizing process of the molten iron 6 containing the chromium, a reduction process of decarburized slag 8 and a slag removing process, at the time of executing the reducing process of the deoxidized slag, the chromium value in the molten iron 6 is measured with an emission spectrum measuring instrument 5 at blowing oxygen firing point and a reduction speed index R value shown with the equation R=([%Cr]2 -[%Cr]1 )/(t2 -t1 ) is measured. Wherein [%Cr]1 is the chromium concn. (wt.%) in the molten iron at the time of passing t1 and [%Cr]2 is the chromium concn. (wt.%) in the molten iron at the time of passing t2 .  Since the point of time when reduction speed index R value starts to lower, while reducing the flow rate of the top-blown oxygen, inert gas is mixed with the top-blown oxygen and the chromium in the decarburized slag is reduced and recovered into the molten iron without lowering the total blowing gas flow rate.
