摘要:
A method for producing one or more coating on a displaccable substrate in a vacuum chamber with the aid of a residual gas, by means of a sputtering device said coating being formed from at least two constituents, whereby a sputtering material of the sputtering device constitutes at least one first constituent and a reactive component of the residual gas constitutes a second constituent. The method comprises the following steps: reactive deposition of a coating on the substrate by the addition of a reactive component, with a predetermined stoichiometric deficit of the reactive component in a zone of the sputtering device; displacement of the substrate with the deposited coating into the vicinity of a plasma source, which is located in the vacuum chamber at a predetermined distance from the sputtering device; modification of the structure and/or stoichiometry of the coating by the action of the plasma of the plasma source, preferably by the addition of a predetermined quantity of the reactive component, to reduce the optical loss of the coating. The aim of the invention is to reduce the optical loss of the multilayer coating to below a predetermined value in a zone of the second coating adjoining the first coating. To achieve this, an interface is created with a thickness d1 and a value for the deficit of the reactive component DEF that is less than a value DEF1.

A plasma source generates a plasma beam that is extracted from a plasma generated by electric and magnetic fields. An RF electrode device includes an excitation electrode having an excitation area, and a plasma space is arranged between extraction electrode and excitation area. The plasma, relative to the extraction electrode is at a higher potential which accelerates positive plasma ions, and the plasma and the extracted plasma beam are influenced by a magnetic field. At least one magnet north pole and one magnetic south pole generate the magnetic field. Each are arranged such that a curved magnetic field projecting into the interior of the plasma space is formed. At least one of the north or south poles is embodied in elongate fashion to form a tunnel-like region in the plasma, in which charged particles are held and along which the latter can propagate.

The invention relates to a test glass changing system (10) for selectively coating and optically measuring a test glass (24, 24″) in a coating chamber (1) of a vacuum coating installation (3). In the coating chamber, a movable turntable (2) is used to guide substrates (7) on a path through a stream of a coating material. The test glass changing system (10) comprises a test glass holder (8, 8″) with a test glass plate (26) for holding the test glass (24, 24″), and a cover (28, 28″) for selectively covering the test glass plate (26). The test glass changing system (10) also comprises a rotary apparatus (34) for rotating the test glass plate (26) about an axis (51) which is oriented approximately parallel to the axis of rotation (5) of the turntable (2). The test glass holder (8, 8″) can be positioned on the turntable (2) and removed from the coating chamber (1) in the form of a unit.

A barrier discharge device (4a, 4b, 4c) installed in a vacuum chamber (1) consists essentially of at least two facing electrodes (20, 22); a dielectric (22) situated between the electrodes (20, 22) and in the immediate proximity of one of these electrodes (20); and a power source (26), which is connected electrically to the electrodes (20, 22). The plasma particles and UV radiation generated during the electrical discharge between the electrodes (20, 22) pass through the electrode (22), which is permeable to UV radiation and plasma particles, and thus emerge from the discharge space. On the surfaces (5a, 5b), the UV radiation induces a photochemical cleaning process, and the impinging plasma particles induce a plasma-chemical cleaning process. The cleaning process is essentially independent of pressure and can be used at pressures of up to 10 bars, which means that the cleaning process can be operated in particular during the time in which the vacuum chamber (1) is being pumped out.

Sputtering system for cathode sputtering apparatus, having a cathode base body with a target of the material to be sputtered. In the marginal part of the target an anode is disposed which is provided with at least one groove. For the solution of the problem of obtaining stable operating conditions in the lengthy coating of substrates with insulating materials and of drawing a high portion of the cathode current to the anode for a long period of time, the at least one groove opens, in accordance with the invention, on a side of the anode that is not in line of sight with the target.

A method of producing glass sheets having good transmission behavior in the visible spectrum range and having good reflection behavior as regards heat radiation. A transparent substrate S is coated by cathodic atomization with, successively, a first oxide layer 1 comprising indium oxide, tin oxide or mixtures thereof, a layer 2 consisting of silver in a thickness of 5 to 50 n, a metallic layer 3 selected from aluminium, titanium, tantalum, chromium, manganese and zirconium in a thickness ranging from 1 to 5 nm and applied directly to the silver layer 2 for the purpose of maintaining the condition thereof, and a final protective oxide layer 4 of indium oxide, tin oxide or mixtures thereof.
摘要:
Solar-controlled glazing having a transmission of between 5 and 40% in the visible spectrum range and having heat-reflection properties is produced by applying an oxide layer having an optical thickness of between 20 and 280 nm directly to a transparent substrate by cathodic evaporation in an oxygen-containing atmosphere to form a first layer. A chromium nitride layer having a geometric thickness of between 10 and 40 nm is then applied in an atmosphere consisting of inert gas and nitrogen to provide a second layer. An optical third dielectric layer may be applied to the second layer. The oxide layer is selected from oxides of tin, titanium and aluminium.

Various exemplary embodiments of the present invention would provide a back floatation panel comprising an inner panel and an outer panel. The inner panel and the outer panel would be joined to each other in such a way as to allow “bellowed” expansion of a space, or a “sleeve,” in between the inner and outer panels. The bellowed expansion space between the inner and outer panels would be adapted for accommodating, for example, a hydration bladder and/or an insert of high density polyethylene (“HDPE”) plastic for protecting the wearer's back. The inner and outer panels would be joined in such a way as to provide a pathway through which a hydration tube can be inserted. Various exemplary embodiments of the present invention would provide differentially cut fabric panels for covering buoyancy panels. An outer fabric panel, comprising an outer panel surface area, would be used to cover an outer surface of a buoyancy panel. An inner fabric panel, comprising an inner panel surface area, would be used to cover an inner surface of the buoyancy panel. In various exemplary embodiments, the outer panel surface area would be greater than inner panel surface area. That is, the outer panel would comprise a greater number of square inches of fabric than will the inner panel. Various embodiments of the present invention would also provide slit buoyancy panels to allow the buoyancy panels to contour over three-dimensional shapes. Various exemplary embodiments of the present invention would provide a personal floatation device with a belt pivotally connected to a back panel of the personal floatation device. Various embodiments of the present invention would provide front floatation panels for a personal floatation device comprising an upper buoyancy panel, a lower buoyancy panel, and a baffle system separating the upper buoyancy panel from the lower buoyancy panel.
