Title: Contour line detecting method for color picture
Inventor: NAKASU EISUKE
IPC: H04N9/74
Filed: 1987-06-25
Abstract: PURPOSE: To detect and assume the contour line of an area to be extracted with a high probability by starting from the designation of the rough position of the contour line and the limitation of picture information and sequentially raising the accuracy of the contour line according to respective processes.  
     CONSTITUTION: An operator refers to a displayed picture displayed on a display device 23, a contour line searching area is designated with a thick line by the use of an area designating means 24 so as to include the contour line of the area to be extracted and stored in a searching area memory 25. A color picture transforming means 26 transforms input color picture data to a brightness of color component and two types of color components and stores in a picture memory 22. An area dividing means 27 successively extracts the area of a similar color based on a histogram in the sequence of at least two types of color data and brightness of color data in the contour line searching area and records a result in a color picture dividing memory 28. Then, a contour line assuming means 29 obtains the boundary of the area from the contents of the color picture dividing memory to calculate the difference of the color from a near picture element and the difference of the brightness of color by the use of the data of the picture memory 22 and assume the contour line of the area to be extracted.

Title: Pump
Inventor: HAYASHI YOUJIROU
IPC: F04D7/06
Filed: 1983-08-31
Abstract: PURPOSE:To reduce the dimension of an overflow recovery apparatus and increase the capacity of a static-pressure bearing by allowing a pump liquid tank and the suction part of an impeller to communicate each other through a passage formed at the top edge part of the shaft of the impeller and reducing the pressure in the upper edge part of the static-pressure bearing in emergency. CONSTITUTION:A horizontal hole 12 for communication to the bottom part of a pump liquid tank 7 which is installed over a static-pressure bearing 3 for supporting an impeller 2 is formed in a shaft 9, and a vertical hole 13 for communication to the suction part 2a of the impeller 2 is formed on the shaft 9. Said horizontal hole 12 is formed at the position below the lowest liquid level in the pump liquid tank 7 in the case when holes 12 and 13 are not formed, in emergency when the pump discharge pressure can not be expected. Since the fluid which flows into the pump liquid tank 7 through a static-pressure bearing 13 is returned into the suction part 2a of the impeller 2 through holes 12 and 13 in ordinary case, overflow amount reduces. In emergency, fluid leaks into the pump liquid tank 7 by the pressure difference between the feed pressure into the static- pressure bearing and the pressure in the upper edge part of the bearing 3, and therefore the capacity of the static-pressure bearing is improved.
