Patent DE-2939044-A1 (DE)
Inventor: BOHLEN HARALD DIPL PHYS
IPC: H01J37/304
Filed: 1979-09-27
Abstract: The mutual alignment of mask and substrate patterns of a specific semiconductor structure are attained by use of a plurality of individual marks in a specific geometric position with respect to each other. By the arrangement of openings in the alignment pattern of the mask, the broad electron beam is split into a multitude of individual beams which interact with alignment marks on the substrate. The interaction is used to generate a coincidence signal. The signal to noise ratio of this arrangement is determined by the overall current and is comparable to that of a thin concentrated electron beam. Registration is effected in a small amount of time and the disadvantageous effects of the high current density used in the raster process are not a factor. In a preferred embodiment, the alignment pattern of the mask is a matrix with center spacings of openings increasing upon advance in two directions perpendicular to each other such that no distance can be represented by the sum of smaller distances. Alignment signals are provided by detecting either absorbed or reflected electrons. A plurality of detectors in the mask are used to detect the reflected electrons.

Title: Regenerator for domestic ion-exchange water-softener - feeds conc. brine at controlled rate into fresh-water by=pass conduit
Inventor: HEISSMEIER WALTER DIPL PHYS
IPC: B01J49/75
Filed: 1980-04-24
Abstract: A regenerator for the ion-exchange water-softener of a domestic washing machine, etc. comprises a salt container with a false floor beneath which is a collecting trough for conc. brine produced by dissolution of the salt. The fresh-water inlet to the water-softener is divided into two branches, one of which discharges into the top of the salt container, whilst the other branch by-passes the container and unites with the outlet of the brine trough, whereby the water flow through the conduit draws the brine from the trough at a controlled rate, simultaneously diluting it to the required degree. This is a simple, reliable arrangement which allows the concn. of the brine to be regulated by varying the ratio of the flow through the salt container to the by-pass flow.
