Abstract: An appliance for removing hairs growing from skin is provided with a clamping device and a cutting device cooperating therewith. The clamping device clamps the hairs to be removed and subsequently extracts them at least partly from the skin, whereupon the hairs extracted partly from the skin are cut through adjacent the skin by the cutting device. The hairs thus cut through return to below the surface of the skin, so that a smooth shaving result is achieved which remains intact during a considerable period. According to the invention, the appliance is provided with structure for adjusting an extraction distance over which the clamping device extracts the hairs from the skin before they are cut through by the cutting device. In a special embodiment, the structure is adjustable to a first mode in which the appliance purely has a shaving function and to a second mode in which the appliance purely has a depilation function.

Abstract: In a projection display device based on one or more (twisted nematic) LCDs (4), simple temperature compensation is possible by optimizing the d..DELTA.n value (n) at the maximal operating temperature. The associated transmission/voltage characteristics at different temperatures then extend substantially parallel so that it is possible to compensate for temperature changes by means of a simple voltage compensation.

Abstract: The invention relates to a method of depositing a metal on a heat-conducting substrate, in which a surface (2) of the substrate is irradiated at at least one area (3) in a bath by a laser beam and the metal is deposited from the bath at that area (3) on the substrate (1).In order to improve the localization of the deposited metal at the irradiated area and in its immediate surroundings, according to the invention, the metal is deposited on a layer (7) of the substrate (1) located at least at the irradiated area (3) and in its non-irradiated surroundings.The layer (7) has a heat conduction coefficient which is smaller than the heat conduction coefficient of the material of the substrate (1) adjoining the layer (7).

Abstract: Producing metal images or patterns on and/or below the surface of a substrate material comprising a semiconducting light-sensitive compound, such as titanium dioxide or zinc oxide which after exposure of a metal compound releases this metal in the form of nuclei. Exposure takes place in the solution of the metal compound by means of a moving beam of laser light whereby the nuclei pattern is directly "written". Thereafter, the nuclei image is intensified in known manner to produce a visible image or a conductive pattern, for example by means of an electroless plating solution. Use: the recording of information as well as the production of printed circuit boards.
