摘要： The known processes require a considerable amount of apparatus for low-pressure glow discharges in order to distribute the generator output to the two electrodes and to control it statically and dynamically. Up until now it has not been possible to achieve this control for high energies and over a great range of frequencies. A process variable measured in-situ should be controllable and adjustable. According to the invention, the direct voltage is produced by means of a four-quadrant d.c. power supply. For this the d.c. power supply is decoupled on the alternating voltage side and connected with one pole to the alternating power supply and with the other pole to an electrode of the bipolar glow device. The direct voltage is set dependent upon a process variable of the glow discharge so that a specific ratio in the power distribution between the two electrodes results. The invention is applicable in plasma treatment of surfaces, deposition of coatings from the plasma and plasma enhanced surface cleaning.

摘要： The greatest possible power is to be supplied to the low-pressure discharge at the median point of a period of time. The same power is to be supplied to each pole although the impedance differs widely. In a plasma and surface treatment technology plant with at least two electrodes and a power supply, the outputs of at least two potential-free d.c. power supplies are connected in such a way that an output of one of them is conductively connected to that of the other having the same polarity. Via a switch connected to the electrodes by each line, the other outputs of which are connected together to the other outputs of the d.c. source, said switches are actuated at the rate of the pole change frequency by a clock unit. The switches are opened on the occurence of an arc discharge. The process is used in bipolar pulsed sputtering for depositing electrically insulating coatings on workpieces. Such coatings are preferably used for mechanical protection, wear prevention and the improvement of sliding properties.

摘要： The object of the invention is to achieve a high and stable deposition rate over a long period of time in order to apply preferably reactive layers of electrically insulating compounds. Reactivity, energetic activation and layer composition and structure should be regulated and kept constant by acting on the plasma density. For that purpose, vapour propagates from the vaporiser (1) through a plasma produced between electrodes (1, 1') and interacts therewith. The electrodes are made of a material to be vaporised or of a component and/or doting material of the layer to be applied. The plasma is maintained in the vapour of the material to be vaporised and/or in an inert gas. This process is suitable for improving the surface of semi-finished products and assembly units, in particular for applying oxide layers with barrier effect on plastic foils in the packaging industry.

摘要： The generator must be statically and dynamically matched to the electrodes in the high power and frequency range in order to perform dipolar low-pressure glow processes. The prior art processes either require considerable complexity or are not usable in the range. According to the invention, the operating time during the positive and/or negative half-wave is controlled in such a way that no power is fed to the glow device, at least during the time of a part of a negative and/or positive half-wave. The invention is applicable to plasma surface treatment, the separation of layers from the plasma and plasma-enhanced surface cleaning.

摘要： The prior art processes for vapour deposition by applying the deposition material consisting of several components (alloys, mixtures, compounds) do not ensure good coating quality. The coatings are difficult to deposit with a constant composition and thickness. According to the invention, the X-radiation emitted by the deposition material at the point of impingement of the electron beam is measured in situ. The signal obtained is used as a guide to control the deposition process parameters and hence to regulate the rate of coating and the composition of the coating applied. The process is applicable to the production of corrosion-proof, high temperature-resistant, low-wear or optical coatings, e.g. on steel strip or plastic films.

摘要： Prior art laminated systems consist of alternately applied silver and metal oxide layers. The reactive sputtering of the metal oxide layer destroys the underlying silver layer and thus its effectiveness. To prevent this anoxidation, a blocking layer of metal is applied between the two layers, which increases the complexity. According to the invention, the metal oxide layers are applied from the two metal sputtering electrodes alternately operated at different polarities. The silver layers are applied in a vacuum in the prior art manner. The pole change frequency is 30 to 80 kHz. The laminated systems are preferably applied to glass and are used for window glazing.

摘要： In the known methods for controlling vacuum coating processes, measurable variables such as plasma emission and coating rate are measured in the plasma or vapor in order to control the vacuum coating process using process parameters of the vaporization or sputtering. This subjects the sensors to high levels of stress, which adversely affects their durability. Using the force of the electrical discharge as a measurable variable, the plasma enhanced vacuum coating process is controlled by measuring the force of the electrical discharge on the coating source. The coating source is arranged in the vacuum chamber with the aid of force transducers (3), and the signal emanating from the force transducers can be used to control, for example, the electrical energy to heat the vaporizing material, the beam deflection or the distribution of the electrical discharge to several coating sources, without the sensors coming in contact with the plasma or the vapor. Plasma enhanced vacuum coating processes, particularly for coating tools and sheet substrates with functional coatings, can be controlled with this method and device.

摘要： Known heat protection foils have several metal layers which reflect thermal radiation and let light through. Systems of alternating metal and non-metal layers are also known. Their disadvantage is that in particular the metal layers are subject to corrosion. The outermost protection layer is not sufficiently scratch-resistant either. Consequently, such heat protection foils may hardly be used on the outer side of glass panes. They are not weather-resistant either. According to the invention, a selectively reflecting system of alternating layers is applied on the plastic foil, together with an anti-abrasive layer. The system of alternating layers consists of corrosion-resistant metal, oxide, nitride and/or oxinitride layers. The anti-abrasive layer consists of an at least 1 mu m thick, highly transparent and homogeneous amorphous oxide layer with high packing density and a micro-hardness of at least 4 Gpa. These layers are applied by high-speed sputtering by means of a dual magnetron. The anti-abrasive layer is applied by plasma- and/or ion-assisted high-speed vapour deposition. This heat protection foil may be applied on the outer side of window panes of buildings and vehicles.

摘要： A process and system for plasma-activated electron-beam vaporisation are disclosed. Known processes are not suitable to achieve very high coating rates under an intensive plasma influence. The spectrum of materials capable of being deposited should be very large, even in the case of insulating layers. The efficiency of the process should be high. According to the invention, the material to be vaporised is vaporised by means of electron beams (7 ) from at least two vaporisation crucibles (1; 1). An electric voltage is applied to the vaporisation crucibles, so that their vapour-generating areas act as electrodes of an electric discharge. The material to be vaporised acts as a cathode or anode. The vaporisation crucibles (1; 1) are connected to earth potential through ohmic resistances (R1; R2). This process and system are preferably suitable for reactive coating large surfaces, as well as for reactive coating components, tools and steel strips (substrate 3).

摘要： The inventive device for digital dental radiography has a source of X-radiation, a detector device, a correcting device and a temperature control device. Said detector device consists of a CCD array on which a scintillator layer is arranged and the radiation geometry of the detector device is constant in relation to the source of X-radiation. The correcting device corrects the electrical signals generated by the CCD array by compensating fluctuations in the electrical signals of the individual elements of the CCD array caused by a dark current of said array elements, by the array elements having different degrees of conversion efficiency and by the inhomogeneity of the scintillator layer. The temperature control device ensures that the detector device remains at a constant temperature during the detection of reference signals and image signals.
