Abstract: The invention relates to a cable with a sheath and an indication material that in case of damaging of the sheath at least partially escapes from the cable.

Abstract: The invention relates to a power supply cord with at least two conductors N, L for transferring a supply voltage with two protective earths insulated from one another, which at the first end are conductively connected with each other and at the second end there is a measurement device provided for measurement of the resistance of a measuring circuit comprising the PE and measurement conductor P, and wherein in case of exceeding the resistance, a warning signal is output.

Abstract: The invention relates to an optically structured filter with predominantly smooth or planar surfaces. Such filters are used as primary masks for the photolithographically manufacturing microelectronic elements, having with at least one pattern with a different transmission in relation to an electromagnetic radiation to be filtered. A filter layer consists of a material of locally homogeneous transmission into which ions, preferably metal ions with an energy of more than 1 keV, are implanted for producing the pattern(s) with the different transmission. This makes it possible to produce filters having patterns with regions of different transmissions for various wave lengths. Suitable materials to be used for the filter layer are materials such as inorganic and organic polymers and glasses as well as mono- and polycrystalline oxides or nitrides. The ion implantation itself is carried out by means of process steps known per se.
