A highly sensitive strain gage containing a thin discontinuous metal layer whose conduction effect is based predominantly on the tunnel effect and which is applied uniformly onto a thin, nonmetallic, dielectric or semiconducting substrate such as uniaxially oriented or partially crystalline plastic film, an ordered ultrathin layer or a silicone-coated plastic film, the diffusion processes in the applied metal layer being reduced and its structural stability improved as a result of interaction of the substrate with the metal layer.

Strain gage having a thin discontinuous metal layer

Optical recording media for recording and retrieval of information by means of high energy radiation, which media consist essentially of a polymeric base having uniaxial orientation and, applied on this, a metal film of high reflectivity having the orientation of the crystallites corresponding to the orientation of the base and retrieval of information are effected by means of high energy radiation.

Optical recording medium

A resist image is produced from a high-resolution, radiation-sensitive resist material by a process in which paraffin is applied as a resist material in a thin layer onto a substrate and irradiated in a predetermined pattern, for example by means of an electron beam, with crosslinking, and the non-irradiated, non-crosslinked parts of the resist layer are then removed. Particularly advantageously, the resist layer consisting of the paraffin is applied onto the substrate by vapor deposition and, after imagewise irradiation, the non-irradiated parts of the resist layer are removed by evaporation in order to develop the resist image.
