摘要:
Method and apparatus for producing metal-coated optical fiber involves providing a length of optical fiber having a glass fiber with or without a carbon layer surrounded by a liquid-soluble polymeric coating. The optical fiber is passed through a series of solution baths such that the fiber will contact the solution in each bath for a predetermined dwell time, the series of solution baths effecting removal of the polymer coating and subsequent electroless plating of metal on the glass fiber. The optical fiber is collected after metal plating so that a selected quantity of the metal-coated optical fiber is gathered, Preferably, the glass fiber passes through the series of solution baths without contacting anything except for the respective solution in each.

Die Erfindung betrifft das Fördern von flachem Gut 1 in horizontaler Ausrichtung in nasschemischen und/oder elektrolytischen Durchlaufanlagen, wobei nur die Unterseite zu behandeln ist. Die Behandlungsflüssigkeit 4 im Arbeitsbehälter 2 reicht nur bis zur Unterseite des Gutes. Die Oberseite darf nicht von der Behandlungsflüssigkeit 4 benetzt werden. Zum Transport dienen an beiden Seiten des Gutes rotierende Fördermittel 6. Die oberen Fördermittel dürfen in den Lücken des in Abschnitten aufeinander folgenden Gutes in der Durchlaufanlage von den unteren Fördermitteln, die sich in der Behandlungsflüssigkeit 4 befinden, nicht benetzt werden. Erfindungsgemäß werden die oberen Fördermittel in den Lücken von der Oberfläche des Gutes bzw. von den unteren Fördermitteln entfernt. Dies geschieht periodisch durch formschlüssige und/oder kraftschlüssige Steuerung der Bewegungen zur Distanzierung der Fördermittel. Eine weitere Ausführung der Erfindung sieht eine Formgebung der Fördermittel als Aussparung 17 am Umfang vor, wodurch die Entfernung von Gut 1 und Fördermittel 6 bei jeder Umdrehung selbsttätig erfolgt. Die Bewegungen sind mit dem Antrieb der Fördermittel der Durchlaufanlage synchronisiert.
摘要:
A coating structure (1, E) for a metal member (10) includes a surface-smoothing layer (11, 13, 14) formed on the metal member (10) for smoothing a surface of the metal member (10), and a fluorine-based film (12) formed on the surface-smoothing layer (11, 13, 14). The fluorine-based film (12) can be formed by applying a fluorine-containing solution (120) on the surface-smoothing layer (11, 13, 14), and by drying the fluorine-containing solution (120). The coating structure (1, E) can be suitably used for a fuel injection nozzle (7).
摘要:
A method and apparatus for applying a uniform membrane coating to a substrate, such as a honeycomb structure, having a plurality of through-channels, wherein the through-channels have an average diameter of less than or equal to 3 mm. The method includes providing a liquid precursor comprising membrane-forming materials to the substrate and applying a pressure differential across the substrate. The pressure differential causes the liquid precursor to travel uniformly through the through-channels, depositing the membrane-forming materials on the walls of the through-channels and forming the membrane on the walls of the through-channels. The apparatus includes a chamber capable of holding the substrate and of maintaining a pressure differential across the plurality of through-channels.

An electroless plating apparatus can form a protective film on exposed surfaces of embedded interconnects stably with good selectivity for thereby protecting the interconnects. The electroless plating apparatus includes a magnetic removal portion for magnetically removing small magnetic suspended solids in an electroless plating solution which have not been removed by a filter.
