摘要：1,106,402. Engraving. STANDARD TELEPHONES & CABLES Ltd. 24 Feb., 1966, No. 8163/66. Heading B6J. A machine for engraving a semi-conductor slice comprises a ferro-magnetic base-plate 1 supporting a work-table 2 and movable in two directions at right-angles, with respect to a head 5 carrying an engraving stylus 4, by means of two rams each driven by a stepping motor under the control of a tape. The slice is contacted by two probes 10 to detect the electrical parameters of the slice, which are altered by the engraving, until a desired state is attained and sensed, stopping the engraving-machine. Each probe is first located with respect to the slice by moving the base-plate as desired, moving the probe base 11 on a member 9 into contact with the base-plate, releasing the base 11 from the member 9 to which it was held electro-magnetically, and electro-magnetically securing the base 11 to the base-plate. The members 9 are raised and lowered by solenoids 7, 8.
