摘要： PROBLEM TO BE SOLVED: To obtain a method and an apparatus in which the distribution function of the magnitude of a single body is obtained without performing an operation to separate the single body, by a method wherein the circumferential length measuring treatment of an extracted image and the image reduction/expansion treatment of a prescribed change amount portion regarding the extracted image are executed repeatedly, and the distribution state of the magnitude of the single body is found on the basis of the change amount of a circumferential length per prescribed change amount. SOLUTION: A sample image is inputted by an imaging device 1, it is stored in a shade image memory 9, and it is binarized and processed so as to be stored in a binarized-image memory 8, At this time, the shading of an image signal level is corrected, a very small noise or the like is removed and the sample image is binarized. Then, the circumferential length of the binarized image is measured, and a measured result is stored in a memory 10 for computing. After the circumferential length is measured, the image which is stored in the memory 9 is degenerated, and image data in the memory 9 is rewritten. Then, a state that the binarized image becomes a background is judged. The measurement of the circumferential length, the storage of the measured result into the memory, the degeneration of the image and the rewriting of the memory 9 are repeated alternately. After that, the differential of the circumferential length is found by a difference method, and the function of a differential area rate is found.

摘要： PROBLEM TO BE SOLVED: To enhance charging depth, and reduce internal resistance by improving the utilization factor of active material. SOLUTION: A sodium-sulfur battery is composed of a solid electrolyte tube 3 in which negative electrode active material 1 made of Na is filled, a positive electrode collector 7 which is impregnated with positive electrode active material 2 arranged on the outer periphery of the solid electrolyte tube 3 and made of S, and holds the same, a positive electrode vessel 5 which contains the positive electrode collector 7, a negative electrode vessel 4 which covers the positive electrode vessel 5, and the like. The positive electrode collector 7 is formed by laminating plural combination body which is the combination of a low density carbon fiber body 7A whose fiber density becomes higher from an inner peripheral side to an outer peripheral side, and a high density carbon fiber body 7B which has higher fiber density than that of the fiber body 7A and is arranged under the fiber body 7A. Therefore, in the low density carbon fiber body 7A the reaction of the active material starts from a high fiber density part so that charging depth becomes high, and by the low density carbon fiber body 7A the decrease of resistance and the hanging down of the positive electrode active material can be suppressed.

摘要： PURPOSE:To suppress the deterioration of beta-alumina-based ceramics due to humidity absorption by coating the beta-alumina-based ceramics with a water repelling material, granulating the ceramics to have prescribed particle size, and then firing the resulting ceramics. CONSTITUTION:A synthetic powder of beta''-alumina, a beta-alumina-based ceramic consisting of beta-alumina, or a ceramic containing both ceramics is coated with a water repelling material. The resulting powder is granulated into 30-100mum particle size and the granulated powder is molded and then sintered. As a result, at the time of production of solid electrolytes, deterioration and size alteration due to humidity absorption before sintering and damage and crack formation attributed to them at the time of sintering are suppressed and formability is improved. a sodium-sulfur battery having the solid electrolyte prepared in that way surely has high reliability. Furthermore, since coating with the water repelling material is done, materials containing water as a main component may be selected as a binder and a solvent at the time of granulation and thus there is a wide option to select binders and solvents.
