Abstract:
An inductively coupled high-frequency electron source is disclosed having a plasma chamber, which is open at least at a first end, the total surface of the open regions of the plasma chamber defined by A0, and having a gas inlet for a gas to be ionized, as well as a high-frequency coil. The interior wall of the plasma chamber is formed at least partially by conductive regions which are connected with a current source, the total surface of the conductive regions defined by Ac, and the ratio of the surface amounts A0 to Ac not exceeding a defined maximal value.
Abstract:
The invention relates to a data carrier with an optically variable structure having an embossed structure and a coating contrasting with the surface of the data carrier. The embossed structure and the coating are so combined that at least parts of the coating are completely visible upon perpendicular viewing but concealed upon oblique viewing so that a tilt effect arises upon alternate perpendicular and oblique viewing. The coating is executed uniformly and the embossed structure is divided into partial areas where different partial embossed structures are provided.
Abstract:
An aqueous emulsion comprises (1) organopolysiloxanes containing SiC-bonded aliphatically unsaturated groups in the terminal units, (2) organopolysiloxanes containing at least 3 Si-bonded hydrogen atoms, (3) a catalyst promoting the addition of Si-bonded hydrogen to aliphatic unsaturation, (4) organosilicon adhesion promoters, (5) silicone resins, (6) an emulsifier, (7) water, and (8) carbon black. The emulsions may be applied to fabric prior to drying and shrinking, and vulcanized while drying the fabric. The coated fabrics exhibit ideal characteristics for use as airbag material.
Abstract:
A data carrier with at least one halftone images 10 represented by structural elements 12, whereby a predetermined symmetrical widening of structural elements 12 represents a corresponding gray level of halftone image 10. Image 10 has predetermined areas 14, 16 and 22 each having a predetermined number or screen frequency of structural elements 12, the screen frequency of structural elements 12 per unit area of area 14, 16 and 22 being different between at least two areas 14, 16 and 22 and/or structural elements 12 being offset from each other in at least two areas 14, 16 and 22. A data carrier with such a halftone image 10 acquires a moiré pattern in at least predetermined areas of halftone image 10 when copied, so that a copy of the data carrier is recognizable immediately and with the naked eye (FIG. 1).
