Abstract: There are provided an electrode that is capable of allowing a current to flow at a uniform current density from the entire surface of a conductive sheet during the passage of a current and that solves the problem of the transfer of metal ions to a living body. The electrode comprises a conductive terminal member formed of a non-metal material; and a conductive sheet formed of a non-metal material and attached to the terminal member, the conductive sheet having a specific resistance lower than a specific resistance of the terminal member. An lontophoresis device and a low-frequency treatment device utilizing the electrode is also disclosed.

Abstract: This invention relates to a motion diagnosis system which picks up motions of a subject and analyzes them, and is characterized by measuring address data at points of images thus picked up according to a trigger condition set in advance, displaying the result of the measurement in graphic images or stored images or in comparison with reference images, outputting the evaluation of such comparison to thereby enable measurement under flexible trigger conditions and analyzing the motions of the subject based on quantitative data in a manner easily understandable by the viewers and simple operation.

Abstract: A proposal for detecting flaws not defining normal stitches in a knitted fabric. Fabric detection signals are derived from three detectors arranged to correspond to intervals between lines of thread defining stitches. The detection signals are then added with predetermined weights, and the signals thus weighted are subjected to adding and/or subtracting operations. As a result, the flaws not defining normal stitches in the knitted fabric are detected. According to this proposal, reliable detection is made of not only large flaws such as circular holes but narrow flaws such as runs also.
