Title: Method and apparatus for continuous casting
Inventor: TAKATANI KOJI
IPC: B22D11/10
Filed: 1989-10-02
Abstract: PURPOSE:To control flow of molten steel in a mold, to improve cleaning effect of the molten steel at meniscus part and to produce a continuously cast slab having sound material by setting two pairs of magnets having the same polarity and two pairs of magnets having the different polarities on both faces at long wall sides of a mold at the time of continuously casting the molten steel. CONSTITUTION:The molten steel is poured into the water cooling type continuously casting mold 3 having rectangular cross sectional shape from a submerged nozzle 1, and solidified shell 4 in the molten steel is formed on inner wall of the mold and pulled out from the mold 3 as the continuously cast slab. In this case, two pairs of the magnets 21 having the same polarity are set as facing at upper side faces of the long walls 3a, 3b in the rectangular mold 3 and two pairs of the magnets 22 having the different polarities are set as facing at the lower part thereof. By controlling fluidity of the molten steel in the mold by magnetic field with the electro-magnets 21, impurity is floated up and separated and breakout in the continuously cast slab caused by remelting of the solidified shell 4 is prevented, and by accelerating flow of the molten steel near the meniscus part by shifting magnet field with the electro- magnets 22, the cleaning effect of molten steel is improved and the continuously cast slab having excellent quality is stably produced.

Title: Data transmission system
Inventor: NASU SHOGO
Filed: 1984-12-06
Abstract: PURPOSE:To improve a bus application factor without producing any deadlock by prescribing the bus opening timing and opening the bus with the prescribed timing only when a buffer is busy. CONSTITUTION:A receiver opens a bus in a time slot (i) and cannot deliver the next request until the next slot (i). Thus it is possible to obtain the timing where the bus is used by all receivers. It is secured for receivers to acquire the bus without fail although the time to acquire the bus is increased in response to the increase of the receivers. However, coincidence is not always obtained between the timing of the end of the data transfer and the timing of the relevant receiver itself in case the bus is opened each time in the same time slot. Therefore, the bus is used wastefully only in a half cycle with the average time slot. Then a deadlock can be avoided if the bus is opened with the timing allocated only in a busy mode of a buffer. Thus the bus application factor is never deteriorated.

Title: Production of high tensile strength hot rolled steel plate
Inventor: KIDO AKIMASA
IPC: C21D9/46
Filed: 1997-09-24
Abstract: PROBLEM TO BE SOLVED: To evade troubles in the production and the violent variation in the plate width by heating a slab contg. specified amounts of one or more kinds among Nb, Ti and V to a specified temp., subjecting it to rough rolling, executing heating so as to regulate the temp. of the rough bar to >= specified one and subjecting it to finish rolling. SOLUTION: A slab contg. one or two kinds among, by weight, >=0.01% Nb, >=0.02% Ti and >=0.02% V is heated to >=1200 deg.C to sufficiently melt carbon nitrides precipitated in the slab, and after that, rough rolling is executed. Since, in the edge parts in the longitudinal and width directions of the rough bar subjected to rough rolling, the reduction of the temp. is drastical to precipitate carbon nitrides, heating is executed so as to regulate the temp. of the part lowest in the temp. to >=1000 deg.C to securely remelt the precipitates. Then, finish rolling is executed at >=870 deg.C so as to suppress the precipitation of carbon nitrides in the process of the rolling as much as possible and to prevent the violent variation in the deformation resistance of the steel.

Title: Identifying device for image area
Inventor: OSAWA HIDESHI
IPC: G06T7/00
Filed: 1986-10-31
Abstract: PURPOSE:To identify the image areas of a character, a line drawing, a photograph and a dotted photograph in image data and judging the picture hue of a noticed picture element based on results obtained by comparing the difference between the average density value of a block and the density value of the noticed picture element, the low and the high frequency components of a special frequency in the block with first, second and third thresholds, respectively. CONSTITUTION:Image data whose gradation is corrected by a gradation correction circuit 3 is inputted to a block making circuit 13 and a picture element in the prescribed size is segmented. A density difference detection circuit 7 takes the absolute value of the difference between the average density value and the density value of the noticed picture element. If the absolute value is smaller than a first threshold, the noticed picture element is decided to be in a halftone image area or in a background area, otherwise, it it decided to be in the image area of which density partly and violently changes. A space filter circuit 8 detects the image edge of a comparatively low frequency and compares it with a second threshold. If the edge is bigger, it is decided that a low frequency edge exists. A space filter 9 compares the image edge with a third threshold, and if the edge is bigger, it is decided that there is a high frequency edge including the dot. Based on these results, a decision circuit 10 identifies the image data on an original in which the photograph area, the character area and the dotted photograph area mixedly exist.

Abstract: PURPOSE:To suppress influence of an eddy current loss in an inner tank due to an inner invasion magnetic flux and to reduce loss in an inner tank based on relative vibration to an outer tank and a superconducting coil of a heat shield by setting resistivity of the shield to a predetermined range. CONSTITUTION:Resistivity of a heat shield 2 is set to a range 20-70muOMEGAcm (corresponding to 4mm of a thickness), i. e., in which an eddy current loss of a refrigerant storage inner tank 3 due to inner invasion magnetic flux due to a harmonic magnetic field. does mot make much increase. Thus the electric resistance of the shield 2 is raised to reduce an eddy current due to a relative vibration of the shield 2 and a superconducting coil 4 of an outer tank 1, thereby effectively reducing a loss in the tank 3 due to reaction. Thus, a refrigerant evaporating amount is reduced, a decrease in refrigerant cooling efficiency is prevented, and superconducting damage can be prevented.
