Abstract: The non-contact type device includes a photo detector (20) for detecting the number of element wires (3), a proximity sensors (22) for detecting the rotation number of a rotating plate (4). The detector (20) detects the number of electric wires (3) per one rotation of a wire rotator (4) which is detected by the sensor (22). The rotation number is counted and accumulated by a counter (24). When the element wire is normal, the accumulated number per one rotation is reset by a comparator (30) and started again to count it.  But if a part of the element wire is cut off, the accumulated number in the counter becomes different and the comparator provides a stop signal to relay (32) for emergency stop.

These compounds are of the formula: <CHEM>  wherein   (1) R<3>, R<4>, and R<5>, together with bonds "a" and "b", form certain lactam-containing moieties similar to those known in the art to have antimicrobial activity; and (2) A, R<6>, R<7>, and R<8> form any of a variety of quinolone or napthyridine structures similar to those known in the art to have antimicrobial activity. y
