Abstract:
Method for manufacturing a workpiece by a vacuum treatment process includes providing a vacuum treatment system with first second parts in a vacuum chamber. Either a sensor or an adjusting element with first signal connection is mounted on the second part. An electronic unit in the chamber has a reference potential and a second electric signal connection. The first part is connected to a system reference potential. A workpiece goes into the chamber and the method includes operating the second part at a further electric potential different from the system reference potential by at least 12 V. The method includes connecting the first electric signal connection to the second electric signal connection and maintaining the reference connection during operation on the further electric potential by metallically connecting the reference connection to the second part.
Abstract:
To provide a film forming method, a film forming apparatus and a manufacturing method of ultrafine particle films, implementing an efficient and proper film thickness control. The manufacturing method of ultrafine particle films includes the steps of: guiding metal ultrafine particles generated in an ultrafine particle generation chamber together with a carrier gas through a conveying pipe to the film forming chamber; and forming a film on a substrate installed over a stage in the film forming chamber through a nozzle, and the evaporated amount of said evaporation material or the thickness of a formed film is controlled by using either the intensity of the emission spectrum intrinsic to an evaporation material or that of the emission spectrum intrinsic to the carrier gas, or else by using both of these.
Abstract:
The invention relates to an apparatus (1) for and a method of applying a substance (16), such as a solution containing an electroluminescent (EL) material or a suspension containing silver particles, to a substrate (7). The apparatus comprises a substrate carrier (5), a nozzle head (12) comprising at least one nozzle (12A) for ejecting the substance (16), and means (2,3,4) for moving the substrate carrier (5) and the nozzle head (12) with respect to each other. It further comprises a first imaging device (13) fixed relative to the nozzle head (12), a second imaging device (9), and one or more references (8) fixed relative to and positioned within the image field of the second imaging device (9). The mechanical link between the substrate (7) and the nozzle head (12) is thus substantially circumvented and inaccuracies originating from this link are avoided.
Abstract:
Methods of analyzing single-walled carbon nanotube structures dispersed in aqueous solutions with dispersal agents are accomplished by depositing the structures in solution on a suitable substrate and forming an array of isolated structures that are substantially free of contaminating material. Transmission electron microscopy and atomic force microscopy are utilized to characterize the isolated structures formed on the substrate.
Abstract:
A detector for monitoring an analyte includes an analyte-sensing composition. The analyte-sensing composition has a visible color intensity or emission intensity (e.g., fluorescence intensity) that changes as the analyte concentration contacting the detector changes. The intensity changes can be visible to the human eye, or identified by an instrument. The analyte can include carbon dioxide, a volatile amine or a volatile carboxylic acid.
Abstract:
A method of painting a product in a production painting facility includes the steps of selecting a hue and a chroma corresponding to the hue. The production painting facility utilizes a plurality of base paints that are mixable to constitute the hue and chroma selected. The base paints are pumped to a blending device in a ratio determined to be necessary to formulate the hue and chroma selected. The base paints are blended in the blending device according to the predetermined ratio forming a secondary paint having the hue and chroma previously selected. The secondary paint is delivered to a paint applicator such as an atomizer bell or an equivalent and is applied to the product being painted. The base paints are mixed at the production facility to create a virtually limitless number of secondary paint colors with only a limited number of base paints.
Abstract:
Sand casting is an old art. In this molding process sand is compacted around a pattern and the pattern is removed, leaving a mold cavity the shape of the pattern. Molten metal can then be poured into the cavity to form the object. To increase the life of the mold, and to make removal of the pattern easier, the pattern must be coated with a protective material. Despite many available pattern coating compounds, mineral seal oil, and a mixture of mineral seal and clay, have been the commercial choices. Hereby the advantages of mineral seal oil-clay pattern coating compositions are retained without its detriments by utilizing a vegetable oil base in a pattern coating composition to replace some or all of the mineral seal oil to provide biodegradable coating compositions with reduced VOC content.
Abstract:
A plasma process reactor is disclosed that allows for greater control in varying the functional temperature range for enhancing semiconductor processing and reactor cleaning. The temperature is controlled by splitting the process gas flow from a single gas manifold that injects the process gas behind the gas distribution plate into two streams where the first stream goes behind the gas distribution plate and the second stream is injected directly into the chamber. By decreasing the fraction of flow that is injected behind the gas distribution plate, the temperature of the gas distribution plate can be increased. The increasing of the temperature of the gas distribution plate results in higher O2 plasma removal rates of deposited material from the gas distribution plate. Additionally, the higher plasma temperature aids other processes that only operate at elevated temperatures not possible in a fixed temperature reactor.

An apparatus and method for measuring viscosity or related properties of fluid samples in parallel is disclosed. The apparatus includes a plurality of tubes and reservoirs in fluid communication with the tubes. The tubes provide flow paths for the fluid samples, which are initially contained within the reservoirs. The apparatus also includes a mechanism for filling the reservoirs with the fluid samples, and a device for determining volumetric flow rates of fluid samples flowing from the reservoirs through the plurality of tubes simultaneously. The disclosed apparatus is capable of measuring viscosity or related properties of at least five fluid samples simultaneously. Useful reservoirs and tubes include syringes.
Abstract:
A radiant light from a reaction chamber is measured outside the chamber, and a relation between a change of a radiation ratio of the radiant light, and a change of a thickness of a thin film is acquired, when a CVD apparatus is used to form the film on a substrate in the chamber. After acquiring the relation between the change of the radiation ratio and the change of the film thickness, the change of the radiation ratio is measured, when the CVD apparatus is used to form the film. The thickness of the film is estimated from the change of the radiation ratio measured in measuring the change of the radiation ratio from the relation between the change of the radiation ratio and the change of the film thickness acquired in acquiring the relation between the change of the radiation ratio and the change of the film thickness.
