IPC: C21D9/00
Filed: 1979-01-24
Abstract: PURPOSE: To enhance an accuracy for estimate for steel strip extraction temperature by a method wherein temperature control is adapted to specific section of steel strip in continuous heating furnace, and furnace temperature is corrected so that estimated temperature of steel strip at scheduled extraction time will  become the target temperature.  
     CONSTITUTION: Moving steel strip on the skid is heated in the continuous heating furnace. Temperatures are measured on the upper and lower atmosphere in the furnace at preheater, heater, and uniform heater zones. Then, atmosphere temperature distribution of the lower and upper of the furnace are obtained in the lengthwise direction and corresponding to temperatures in each zone. Similarly, cooling water temperature in the skid cooling pipe is measured and cooling water temperature distribution in the furnace lengthwise is obtained. Current temperature at each section of steel strip 2 is every minute calculated by use of the distribution curve. Also, later-time temperature at each section is calculated for the time at which the steel is extracted. From this result, the atmosphere temperature is controlled so that the steel strip temperature at the scheduled extraction time will approach the target temperature. As a result, steel strip which is uniformly heated to the target temperature can be extracted.

Title: Extraction device for axial compressor
Inventor: KATO YASUHIRO
IPC: F04D29/54
Filed: 1986-01-20
Abstract: PURPOSE:To enable the stable operation of a compressor over the whole operating range from a low rotation area to a high rotation area (by providing a bleed air guide vane the installing angle of which is in the same direction as the rotating direction of a moving vane, in the flow passage of an extraction port) and removed the cause of unstable flow in an extraction part. CONSTITUTION:Extraction guide vanes 13 built on the surface of an upper stream position casing inside a slit type extraction port 5, are provided in an extraction flow passage. Plural number of said extraction guide vanes 13 are arranged in the circumferential direction in the slit type extraction port 5 and the installing angle alphaof the extraction guide vane 13 is in the same direction as the rotating direction 9 of a moving vane 2. By this structure, at the time of low speed rotation which requires extraction, an extraction flow 14 is uniformly introduced into a discharged chamber 6 along the extraction guide vanes 13 and, then, discharged out of a discharge pipe 7. At the time of high speed rotation which does not require extraction, the extraction guide vanes 13 function as a large passage resistance against a flow (broken line arrow mark 15 in the figure) from the discharge chamber 6 without causing such a reverse flow against a main stream. Accordingly, a stable operation can be obtained over the whole operating range of a compressor.

Title: Method and device for detecting superimposed character in image and record medium for recording the method
Inventor: ARAI HIROYUKI
IPC: G06T7/00
Filed: 1998-01-20
Abstract: PROBLEM TO BE SOLVED: To provide a method and a device for detecting superimposed character in an image with which the superimposed characters in an image to be displayed while moving can be exactly detected as one set of character strings at high speed. SOLUTION: A frame image is acquired at a certain time interval from images and a featuring point to appear in a character part as a feature is detected from each frame image. Appearance of superimposed characters is detected from spatial distribution of this featuring point and the moving amount of entire superimposed characters is calculated by collating the detected frame image with the featuring point of a frame image acquired continuously. While using this moving amount, the coordinate value of one image is transformed so as to spatially overlap superimposed characters to be commonly displayed between frame images, then, the featuring points detected in respective images are locally collated, and the value of local deviation at respective character parts of superimposed characters is calculated.  The local deviation is corrected by performing suitable geometrical transformation to the image part where the local deviation is detected. Thus, superimposed characters to be commonly displayed between frame images can be exactly made correspondent each other.
