Abstract: A universal cold-cathode type ion source with a closed-loop electron drifting source and with an ion-beam propagation direction perpendicular to the plane of electron drifting is intended for uniformly treating stationary or moveable objects with such processes as cleaning, activation, polishing, thin-film coating, or etching. The ion source of the invention allows adjustment of beam parameters and configurations and has an ion emitting slit of an adjustable geometry. In one embodiment, the adjustment is carried out by changing the width of the slit by shifting moveable parts of the cathode in the direction perpendicular to the direction of the ion beam. In another embodiment the slit configuration is adjusted by shifting a moveable part of the cathode in the direction of the beam propagation. The invention also provides a method for adjusting the shape and configuration of the ion beam with respect to the object to be treated.

Abstract: A multidirectionally stretch-crazed microencapsulated polymer film having a matrix material and microcapsules which are formed in the matrix material in the form of crazes which are filled with an encapsulated substance (30, 30a) and oriented at least in two mutually intersecting directions X and Y. The filled crazes form a net-like structure. The microencapsulated film is produced by stretching the original film under a controlled rate of stretching in two intersecting directions in an environment of a surface-active substance with or, if necessary, without a material to be encapsulated. When stretching is discontinued, the crazes are closed and encapsulate the material.
