Abstract:
A method and an arrangement in connection with a production line for optic cable, wherein optical fibers (1) are guided to a coating point (3), where filling gel is applied around the fibres, and a loose tubular casing is formed around the fibres and the filling gel. The fibres (1) are guided to the coating point through a device (4) that is formed from three parts (4a, 4b, 4c), said device being supported on a first base (5) and on a second base (6) moving in the travel direction of the fibres. Sensors (7, 8) are arranged in the first and second bases (5, 6) for measuring the force acting on the bases (5, 6). The arrangement further comprises means (9) for calculating the difference between said measured values for determining the friction force between the fibres and the tubular device (4).
Abstract:
An applicator apparatus for controlling the uniform (or predetermined non-uniform) application of a treating fluid to a traveling fabric, web or other substrate includes one or more fluid applicators, each having spaced apart housing or body walls interconnected by a body edge preferably of a generally parabolic shape. Each applicator includes a fluid inlet in one body wall and a transversely elongated fluid outlet in the opposite body wall. The body walls define a fluid distribution chamber extending substantially equally and oppositely relative to the fluid inlet, with the chamber being divided by a plate member having preferably generally parabolically shaped peripheral edges substantially corresponding in shape with and spaced inwardly from the body edge.
Abstract:
In a coating apparatus, a nozzle connects a feed pipe for feeding a coat solution to a manifold of a die with an opening of the manifold. The nozzle satisfies conditions: 1.5nullB/Anull5.0 and 0.8nullC/Bnull8.0, when A is an equivalent diameter of an end of the nozzle to be connected with the tube, B is an equivalent diameter of another end of the nozzle to be connected with the opening, and C is a length of the nozzle. The coat solution fed from the feed pipe enters in the nozzle. In the nozzle, the coating solution diverges along with an inner wall of the nozzle to enter into the manifold. In the manifold the coating solution flows in a widthwise direction and flows out through a slit extending from the manifold to a lip of the die, such that a moving web is coated with the coating solution uniformly.

Abstract:
A process for the extrusion of microcellular polymeric material onto data communications material such as wire and optical fiber is described. Electrical conductors and optical fibers coated with microcellular polymeric material exhibit unexpected strength sufficient to pass certain industry tests necessary for use in a variety of applications, even without an exterior coating of structurally-supporting polymeric material. Polymeric microcellular materials provided in contact with the electrical connectors for a variety of purposes are described where the strength of microcellular material provides required structural support.
Abstract:
The invention provides an electrode forming method with steps of arraying chip-style electronic components on an arraying flat bed thereby positioning and aligning the components, lowering a film coated with an adhesive in relative manner together with an adhering top plate parallel to the arraying flat bed thereby adhering ends of the positioned and aligned chip-style electronic components to the adhesive, then lowering the first film to which the chip-style electronic components are adhered in relative manner together with a coating top plate parallel to a coating flat bed provided with a conductive paste layer of a constant thickness thereby pressing the other ends of the chip-style electronic components to the coating flat bed and coating the ends of the electronic components with the conductive paste.

A coating method of coating an outer circumferential surface of a cylindrical base with a coater having a supply port, a coating solution chamber, and a slit communicating with the coating solution chamber, the slit being provided around an inner circumferential surface of the coater, comprisse steps of: feeding a coating solution from the supply port to the coating solution chamber so that the coating solution is discharged to the slit; adjusting an absolute pressure P in the coating solution chamber so as to satisfy the following formula: 3null104nullPnull3null106 (mmH2O) and relatively moving the cylindrical base through a hole formed by the inner circumferential surface of the coater so that an outer circumferential surface of the cylindrical base is uniformely coated with the coating solution flowing out from the slit.
Abstract:
A plate and a substrate are placed to face each other and a treatment liquid is jetted from a treatment liquid jetting portion of the plate, thereby treating the substrate. At this time, bubbles in the treatment liquid are discharged from an opening formed in the plate, thereby enabling reduction in treatment nonuniformity caused by the bubbles. The formation of a slope toward the opening on the plate makes it possible to further promote the removal of the bubbles from the treatment liquid.
