Abstract: An EPROM-like memory includes a substrate having a source region, a drain region, and a channel. The memory includes a gate stack formed by a gate oxide, a storage electrode, a second gate oxide and a gate electrode. The gate oxide is configured on the substrate above the channel. The storage electrode is configured on the gate oxide. The second gate oxide is configured on the storage electrode. The gate electrode is configured on the second gate oxide. The memory includes an interspace that is configured between the drain region and the storage electrode. The interspace is filled with a gas or contains a vacuum. The memory includes an outer spacing web that is configured laterally beside the gate stack. The outer spacing web is also configured on the drain region. The outer spacing web is made of doped polycrystalline silicon.

Abstract: An intaglio ink for printing illustrations comprises C.I. Pigment Yellow 139 and further, preferably chlorine-free organic yellow pigments and has good rheological and coloristic properties which are comparable with those of conventional intaglio printing inks based on C.I. Pigment Yellow 12.

Abstract: Mono- and disazo pigments from the group of the acetoacetarylide, pyrazolone, .beta.-naphthol, 2-hydroxy-3-naphthanilide, 2-hydroxynaphthoic acid, benzimidazolone, diaryl yellow, diarylpyrazolone and disazobenzimidazolone pigments in whose preparation a nonionic surfactant which has a cloud point in aqueous solution was added at the latest immediately prior to the isolation, excluding pigments which have a bis(acetoacetylamino)benzene coupling component, are useful for pigmenting solvent-containing packaging intaglio and flexographic printing inks.

Abstract: Process for the bath pigmentation of leather, which comprises dyeing the leather with pigment dispersions which contain a compound of the formula (I) ##STR1## where Ar is benzene or naphthalene,X is --CH.sub.2 --CH.sub.2 -- and/or --CH.sub.2 --CH(CH.sub.3)--,0 to (m-1) of the radicals A are hydrogen,1 to m of the radicals A are benzoyl and/or naphthoyl,1 to m of the radicals A are --CO--CH.dbd.CH--COOM and/or --CO--CH.sub.2 --CH(SO.sub.3 M)--COOM, where M is a cation,R.sup.1, R.sup.2 and R.sup.3 are hydrogen or alkyl of 1 to 14 carbon atoms,R is hydrogen and/or alkyl of 1 to 9 carbon atoms, n is a number from 1 to 150 and m is a number from 2 to 12,The pigment having an average particle size of 50 to 500, preferably 80 to 300, nm. By using these dispersions, which contain the pigments in a very finely divided form, it is possible to obtain thorough penetration of the leather with improved light fastness.

Abstract: Aqueous pigment preparations which contain (a) 5 to 80% by weight of a finely-divided inorganic and/or organic pigment, (b) 5 to 80% by weight of an aequeous polyurethane dispersion, (c) 2 to 80% by weight of water and (d) 0 to 50% by weight of an organic solvent.
