    摘要： A drilling rate and depth monitor is provided for determining the rate in which apertures are formed in a workpiece using an electro-chemical machining process. The drilling rate and depth monitor is particularly useful where the rate of aperture formation is extremely slow, i.e., less than one-thousandths of an inch per second. The drilling rate includes a position sensor coupled between a workholder and a movable member supporting a plurality of cathodic drilling tubes which yields a depth signal proportional to the distance between the drilling tubes and the surface of the workpiece. Differentiation means are responsive to the depth signal for producing a drilling rate signal and display means are provided for both the drilling rate and drilling depth.

    摘要： A method and apparatus for monitoring an electrical property of a conductive coating on an optical fiber, the method comprising capacitively coupling at least one alternating electrical signal into and out of the conductive coating and measuring an electrical property of the coating carrying the alternating electrical signal. The apparatus comprises generating means for generating an alternating electrical signal; capacitive coupling means for capacitively coupling the alternating electrical signal into and out of the conductive coating, the capacitive coupling means being electrically connected to the generating means; and measuring means for measuring an electrical property of the conductive coating carrying the alternating electrical signal, the measuring means being electrically connected to the capacitive coupling means. A method of manufacturing coated optical fiber which incorporates the method of monitoring an electrical property of a conductive coating is also disclosed.
