Abstract: HEAD ASSEMBLY FOR A JET DROP RECORDER              Abstract Of The Disclosure A jet drop recorder has a head assembly which generates, charges, and switches rows of jet streams arranged along angularly oriented placement lines.  The spacing and angularly orientation of the placement lines are sel-ected so as to produce an effectively uniform side-by-side spacing for the drop streams arranged along the placement lines.  Each placement line may include a large number of drop streams, so that there is produced a recording head capable of high resolution recording.         The drop streams are created and selectively charged by an orifice plate and a charge ring plate having orifices and charge rings in mutual registration.  Below the charge ring plate there is a deflection electrode assembly comprising an insulative member provided with a series of angularly arranged teeth.  Deflection electrodes are plated on opposite sides of the teeth and connected to sources of different electrical potential for generation of electrical deflection fields.  Drops which are charged by application of a charging signal to their associated charge ring are deflected by the deflection field through which they are directed.  The lower surfaces of the aforementioned teeth are configured to define  catchers for drops directed there-toward.  In one embodiment the catchers catch charge drops, and printing is effected by deposition of uncharged drops on a recording medium transported below the recording head.          In an alternative embodiment the catchers catch uncharged drops, and printing is accomplished by deposition of charged drops on the recording medium.

Abstract: ABSTRACT           A microscopic length scale typically about 50 µm long and graduated in several intervals ranging from 1 µm to 20 µm.  The scale is useful in calibrating the magnifica-tion of scanning electron microscopes (SEMs) and other electron imaging instruments.  The scale comprises alterna-ting layers of two metals deposited on a substrate.  The two metals have substantially different electron emission coefficients to provide contrasting emission signals when scanned by an electron beam.  On of the metals, preferably gold, is deposited in uniform layers about 40-80 nm thick.          The other metal, preferably nickel, is deposited in several layers ranging from 1 µm or so thick near the substrate to 20 µm thick in the outermost layer.  The resultant multilayer composite is cut into one or more samples and each sample is mounted on edge.  The exposed edge is ground and metallographically polished and a microscopic indentation is made in the substrate near the first gold layer.  The indentation defines a reference region, and the distances between the first gold layer and the subsequent gold layers in the reference region are measured.  The measurement is made using a similar sample which was previously calibrated with the aid of a polarizing laser interferometer.
