  • Publication number: 20160308181
    Abstract: A degassing hole is formed in a casing in which a storage element is housed. Prior to forming the degassing hole, the casing is clamped in a region between the outer peripheral edge of the casing and the storage element where the degassing hole is to be formed such that overlapped films of the casing are pressed tightly together. By displacing the acting position of the clamping force toward the storage element while reducing the clamping force gradually toward the storage element prevent, liquid spill in a degassing process is prevented.

  • Patent number: 5675714
    Abstract: A mode identifying method of identifying a mode to which inputted code data belongs is provided. An inherent code existing in each mode so as to have a probability-manner relation and the probability-manner relation are stored so as to correspond to each other. A code which coincides with the inherent code stored is extracted from the code data and the number of coincidence times of every code is counted. The mode to which the code data belongs is identified on the basis of the number of coincidence times obtained by the counting step and the probability-manner relation stored by applying a multi-value logical relation or a fuzzy logical relation or both of a fuzzy rule and a fuzzy inference to the number of coincidence times obtained and probability-manner relation stored.

  • Patent number: 4414581
    Abstract: An image signal processing method and apparatus for practicing the method are capable of identifying and differentiating information not having tonal rendition such as characters and linetone images from information having tonal rendition such as photographs and pictures, based on the difference of signal characteristics, for example based on the fact that the spatial frequency distribution in portions of an image not having tonal rendition are in the higher frequency range compared to that of the portions of the image having tonal rendition. The method and apparatus are also capable of conducting different processes on the identified different images.
