IPC: H01M8/12
Filed: 1988-04-06
Abstract: PURPOSE:To eliminate an internal basic tube for retaining a lamination material and substantially reduce weight by laminating a fuel pole and a pneumatic pole sandwiching a solid electrolyte film, forming the lamination material into a cylinder after the partial cutting thereof or into a complete cylinder and providing an interconnector along the lengthwise direction thereof for taking out electric current generated in a lamination film. CONSTITUTION:A solid electrolyte fuel cell 11 comprises a fuel pole 12 and a solid electrolyte film 13 at the side of fuel supply and a pneumatic pole 14 at the side of air supply. In this case, the fuel pole 12 is made of Ni, Ni/CSZ cermet and the like, thereby ensuring performance for enough gas transmission and electron conductivity. The electrolyte film 13 is made from YSZ (yttria stabilized zirconia) and the like, thereby obtaining performance for preventing gas and electron transmission, but allowing the transmission of an oxygen ion. LaCoO3 and the like are used as the pneumatic pole 14.

Title: System for extracting feature of character
Inventor: TAKAHASHI SEIJI
IPC: G06K9/46
Filed: 1988-04-06
Abstract: PURPOSE:To improve the performance of a character recognition device to obtain excellent recognition results by providing character frame producing means, shortest distance affixing means, centroid deciding means, progressional row producing means, and normalizing means, and outputting a normalized progression as the feature of a character. CONSTITUTION:A character frame producing means 11 produces a hexadecagonal character frame circumscribing a binarized picture segmented one character by one character, and a shortest distance affixing means 12 finds and affixes the shortest distance form each point on the character frame to a black picture element. A centroid deciding means 13 finds the center of gravity of each polygon formed of the sides of the character frame. Since the center of gravity of the polygon formed of the sides of the character frame is adopted, the center of gravity does not move even if the character is deformed. A progressional row producing means 14 divides the character frame into four parts by drawing two 45 deg.-inclined lines passing through the center of gravity, and arranges the values of the shortest distances at every divided parts counterclockwise from a starting point set at the upper left part. Since the produced four progressions do not always have the same length, a normalizing means 15 normalizes the progressions to the same length. The progressions are outputted as features of the character. Therefore, even when the inside of a character is deformed, the features of the character can be expressed faithfully.
