Abstract: PURPOSE:To make it possible to immediately analyze an abnormal cause, by allowing a memory device to store the voltage drop of the connection wires between an AC power source and a plurality of windings, which are arranged along a moving path, through a low band pass filter and stopping memory renewal when abnormality is generated to detect a moving state. CONSTITUTION:When a control rod begins to fall, a control rod driving shaft 2 being a magnetic body induces electromotive force in winding elements 1a-1e to generate voltage drop in connection wires 13. The output obtained by amplifying said voltage drop by an amplifier 7 and voltage drop due to an AC power source 3 in a normal state wherein the control rod is not fallen are separated by a low band pass filter 8. In addition, the output of the filter 8 is converted to a digital signal by an A/D converter 9 and this signal is stored in a memory device 10 in the relation with time under the control of a control circuit 11 and renewed at every definite time T. In this case, the renewal of the memory of the memory device 10 is stopped by the trip signal of an atomic reactor and the whole of the memory content is allowed to reappear by a recording needle 12 and used in analysis.

IPC: B22D11/16
Filed: 1989-08-22
Abstract: PURPOSE:To hold thickness of pool to the fixed value and to avoid the development of surface defect of slag inclusion, etc., on a cast slab by reverse- proportionally changing the number of oscillation frequency corresponding to casting the casting velocity. CONSTITUTION:In the case of drastically reducing the casting velocity, consump tion of mold powder is drastically increased and as the thickness of pool is reduced, frequency of the development of surface defects on the cast slab is reduced. Further, by reducing the number of oscillation, the consumption of mold powder is increased and the thickness of pool is reduced. In such a way, there are the correlations between the number of oscillation and the thickness of pool and between the thickness of pool and the surface defect on the cast slab, and by utilizing this, the number of oscillation is changed corresponding to variation of the casting velocity and the surface defect on the slab can be avoided.

IPC: B22D11/108
Filed: 1988-08-30
Abstract: PURPOSE:To decrease the transverse corner cracks of an ingot by segmenting the inside of a casting mold to side parts and central part in a specific position and using powder having a low softening point to the side parts and powder having a high softening point to the central part. CONSTITUTION:The inside of the casting mold 8 is segmented to three parts; the side parts 10 in the range of the length of at least 1/4 ingot thickness from the short side 4 and the central part 12 exclusive of these parts. Two kinds of the powders which vary only in the softening point and are the same in the other properties are prepd. The powder having the low softening point is used for the side parts 10 and the powder having the high softening point is used for the central part 10. The inflow of the molten powders near to the short sides 4 is, therefore, accelerated and the rapid cooling is prevented by the adiabatic effect of this powder. The corner transverse crack is prevented by the increase of the inflow of molten steel.

Title: Method for judging completion of primary fermentation of sewage sludge
Inventor: SHIMADA TAKESHI
IPC: G01N30/88
Filed: 1997-07-25
Abstract: PROBLEM TO BE SOLVED: To rapidly and precisely judge the completion of primary fermentation of sewage sludge by measuring the ratio of the low-mol.wt. component to the water-soluble component in a fermentation mixture and judging the completion of primary fermentation when the ratio becomes constant. SOLUTION: The method for measuring the ratio of the low-mol.wt. component to the extracted water-soluble component is not specifically limited. For example, the water-soluble component is transferred to a water phase by extraction, and a part of the water phase, i.e., the water-soluble component having 400-500 mol.wt., is measured by liq. chromatography. Otherwise, the water-soluble component having <=400-500 mol.wt. is separated by a separation membrane such as a reverse-osmosis membrane and then measured by UV absorption, etc. However, the liq. chromatography is most preferably used because of its rapidness and simplicity. In this case, the ratio of the area occupied by the component having a specified mol.wt. (e.g. about 500) or less in the obtained chromatograph to the area occupied by the whole component is used as the index of judgement.
