Abstract: PROBLEM TO BE SOLVED: To provide a highly reliable cell-to-cell connecting part by providing, on a battery jar inner surface making contact with both end electrode plates of an electrode group, a recessed part or continuous rib laid along the outer form of the electrode plates so that the electrode plates are closely fitted to the surface making contact the electrode plates. SOLUTION: A recessed part 2 according to the outer form of electrode plate is formed on a battery jar bulkhead 1' on the inner surface of a battery jar 1 with which both end electrode plates of an electrode group make contact, so that the electrode plates to contact can be fitted thereto. This recessed part 2 is opened to the battery jar upper part, and its upper part 8 has a slightly opened form so that the electrode group can be easily inserted in vertical state along the recessed part 2. Thus, when the electrode group is inserted to the battery jar 1 to perform a cell-to-cell connection, the positional slippage between a cell-to-cell connecting hole and a cell-to- cell connecting part welded to the electrode group upper part after insertion is eliminated to prevent the airtight failure between cells, and the strength of the cell-to-cell connecting part is enhanced.  Otherwise, a continuous rib may be provided on the bulkhead 1' with a height smaller than the thickness of the end electrode plate of the electrode plate group so as not to obstruct the contact of a glass separator with the electrode plates.

Filed: 1999-06-25
Abstract: PROBLEM TO BE SOLVED: To obtain an image processing unit where an image can automatically and effectively be corrected by correcting a chromatic fog of a received image and correcting the contrast of the corrected image. SOLUTION: In the execution of automatic image correction, a chromatic fog is corrected (S40) and then the contrast is corrected (S42). In the chromatic fog correction, first the chromatic fog is discriminated. A color discriminated to be the chromatic fog is converted into an RGB space and a color with the highest RGB value is recognized to be the chromatic fog in RGB colors. In other cases, no chromatic fog is discriminated. Then in the contrast correction, first an RGB histogram is generated to obtain a maximum value and a minimum value of summation of the RGB planes. A coefficient K is obtained so that the image uses out the dynamic range with respect to the obtained maximum and minimum values. Then the coefficient K is applied to each of the RGB planes to extend the dynamic range.
