Title: Ventilating screw duct and method of its manufacture
Inventor: HONDA KOICHI
IPC: G21F9/02
Filed: 2000-02-28
Abstract: PROBLEM TO BE SOLVED: To obtain satisfactory shielding performance, freely design and manufacture one having a size corresponding to the quantity of processing air, and reduce pressure loss, and further reduce the cost. SOLUTION: Many sheet shaped structures 32 each having an opening section 30 are laminated with the openings displaced in their positions to form a spiral ventilating flow passage 34 as a wbole with the opening sections overlapped in succession, whereby a structure having radiation shielding performance is provided. An outer appearance of the sheet shaped structure may be arbitrary, i.e., circular or polygonal. Further, it may be a structure obtained by laminating sheet shaped structures with the same configuration, or may be a combination of different configuration sheet shaped structures. The configuration of the opening section formed in the sheet shaped structure is arbitrary, and is circular preferably hydrodynamically.  The circular configuration of the opening section causes an advantage that a fluid effectively flows through the whole of the opening section while preventing any dwelling part from occurring, which is not only effective hydrodynamically but also prevents radiation shielding performance from being deteriorated because of formation of any wasteful opening.

Abstract: PROBLEM TO BE SOLVED: To obtain an optimal threshold for binarizing a captured color image. SOLUTION: In this method for digital image processing, a captured image is clipped on a DRAM (step S1), a histogram of luminance data of the inputted color image is generated (step S2). A minimum value Ymin and a maximum value Ymax of the luminance are obtained from the histogram in this case, after the setting of the offset value of black side and white side, Ymin and Ymax are obtained (step S3). A difference Ydiff (=Ymin-Ymax) is obtained, and the difference Ydiff is compared to the limiting range Yrange (step S4). When Ydiff>Yrange, a threshold Thr is calculated as an intermediate value, but sometimes an item for adjustment value may be added to the intermediate value (step S5). In the step S4, when Ydiff<=Yrange, the threshold is set at a fixed value (step S6), the captured image is binarized by the obtained threshold Thr (step S7).
