摘要： A communication cable having a communication wire and an armor including at least two synthetic resin layers, and protects the communication wire in a loose state. The communication wire protecting tube includes at least two synthetic resin layers, and inserts the communication wire in a loose state. The most hard resin layer of the armor has a crosswise or spiral annular groove or cut portion continuous in the longitudinal direction to reach the radially inner face, and the outermost layer of the armor is formed of a protective layer made of a softer resin than the hard resin layer. The adjoining edge portions of the annular groove or the cut portion come, when the communication wire is to be bent, into contact with each other so that it may be prevented from being bent to a predetermined or smaller bend radius.

摘要： The present invention relates to an image processing method and image inspecting method with high versatility which enable efficient and highly accurate proof of authenticity of a digital image. The image processing method subjects at least a part of a digital image which can exist temporarily or continuously in a falsification-vulnerable environment, to a first morphology operation using a predetermined structuring element, to process the digital image. The image inspecting method subjects the digital image thus processed, to a second morphology operation using the same structuring element as in the first morphology operation. The morphology operations have the idempotent and the presence or absence of falsification can be detected by determining identity of images before and after the second morphology operation.
