A sound insulation sheet member 1 including a substrate 2 and a concavo-convex structure 3 placed on at least one surface of the substrate 2, in which the concavo-convex structure 3 is provided by repeatedly arranging a plurality of units each defined as a concavo-convex unit shape 4 including a linear convex portion 5, in one direction at substantially constant intervals on the surface of the substrate 2.

An apparatus and a method for improving at least one physical property of an extruded plastic material comprise an extruder for extruding the plastic material as well as a laser unit with at least one laser for irradiating the extruded plastic material with laser light. Further, the apparatus has at least one laser light-reflecting reflector arranged at a distance to the extruded plastic material. The laser and the reflector are arranged and designed such that the laser light emitted by the laser is incident on the reflector through the extruded plastic material, the reflector reflects the incident laser light such that at least a part of the reflected laser light hits the extruded plastic material.

A method for producing an electrically conductive thin film on a substrate is disclosed. Initially, a reducible metal compound and a reducing agent are dispersed in a liquid. The dispersion is then deposited on a substrate as a thin film. The thin film along with the substrate is subsequently exposed to a pulsed electromagnetic emission to chemically react with the reducible metal compound and the reducing agent such that the thin film becomes electrically conductive.
