Abstract: A method wherein a substrate is provided, wherein, in a scanning step, structures already applied to the substrate are detected by at least one scanning provision of a processing head, wherein the processing head is provided with at least one lighting provision, which lighting provision locally lights the applied lacquer structure in a lighting step by using the information obtained with the scanning step. Further, the invention discloses an apparatus for carrying out the method is described, which apparatus is provided with a processing head which is movable relative to a substrate carrier, wherein the processing head comprises at least one scanning provision and at least one lighting provision.

Abstract: There is provided a sunscreen emulsion composition. The composition has an inner discontinuous phase and an outer continuous phase. The inner discontinuous phase and/or outer continuous phase has a sunscreen active therein. The inner discontinuous phase is generally dispersed in the outer continuous phase and is in the form of discrete droplets having a multimodal droplet size distribution. There is also provided a method of protecting skin from overexposure to the sun in which the above composition is applied topically to the skin. There is also provided a method of enhancing the performance of a sunscreen emulsion by forming the inner discontinuous phase as a multiplicity of droplets having a multimodal droplet size distribution. There is also provided a method of preparing an emulsifier-free sunscreen composition.

Abstract: The present invention provides a method for forming a barrier layer, preferably a conductive barrier layer. According to the present invention, a barrier layer is formed from an organometallic precursor in the presence of an oxidant in a low temperature deposition technique using a platinum containing precursor. Such layers are particularly advantageous for use in memory devices, such as dynamic random access memory (DRAM) devices.

Abstract: A buried bit line DRAM cell includes an active region having a protruding tap, formed in a semiconductor substrate. A device isolation region is formed in the substrate, outside the active region. A bit line laterally contacts the tap and is buried in the device isolation region. Accordingly, photolithography steps for forming a device isolation film twice and for forming a bit line contact can be omitted, thereby obtaining process simplicity and wider process margins.

Abstract: The present invention is addressed to providing a simple, yet reliable method for labeling an object for its verification. Broadly, the method of the present invention for labeling an object for its verification commences with applying to a predetermined location on said object, a mark which creates a permanent impression thereof which is perceptible to the unaided or naked eye and a mark which creates a permanent impression thereof which is imperceptible to the unaided or naked eye, yet which can be determined by mechanical, electrical, and/or biologic means. In prior U.S. Pat. No. 5,194,289 a combination of UV eye and amino acid/protein fragment was used to label objects for their identification. The present invention broadens such dual labeled scheme to include a variety of additional "invisible" labeling techniques. Additionally, the present invention includes the recognition that, in order to stop counterfeiting of records and like consumer goods, a visible mark also must be present on the object.

Abstract: Apparatus for heating a silica optical fiber in a fiber-drawing installation. The apparatus is disposed at the outlet of a fiber-drawing oven to raise the optical fiber to a temperature greater than 1000.degree. C. The apparatus is constituted by a microwave generator coupled to a resonant cavity formed by a helically-wound metal wire helix fixed at opposite ends to two short circuit metal plates respectively, with the optical fiber running substantially along the axis of the helix and the helix concentric about the running fiber.

Abstract: A surface of an optical fiber is coated by a method for coating a surface of an optical fiber with carbon comprising steps of introducing an optical fiber in a reaction chamber containing a coating raw material comprising carbon, hydrogen and halogen atoms and depositing on the surface of the optical fiber a carbon layer formed from the raw material by chemical vapor deposition, whereby the coated optical fiber has improved initial tensile strength and absorbs less hydrogen.

Abstract: A coating for improved resistance welding of galvanized steel parts or sheets comprises a binder, and a metal phosphide pigment, preferably a ferrophosphorus pigment, having a particle size of from about 0.1 to about 30 microns. The pigment can also include up to about 40% by weight of an additional metal such as tin, aluminum or lead, which can be combined with the metal phosphide in pigment form or deposited onto the surface of the particles. The coating can be applied to either the faying or non-faying surfaces of the galvanized steel, or to the resistance welding electrode, and may be removed, if desired, after the welding operation.The advantages of the present invention include a significant reduction in welding current and an increase in the weldability lobe width, a restoration of the dynamic resistance beta peak, and an increase in electrode life.
