Abstract:
A first coating rod placed on an upper-surface side of a resin film is pressed onto the resin film in a state where the first coating rod is circumscribed and supported by support members each comprising a pair of rollers and spaced with intervals therebetween in a length direction of the first coating rod so that the first coating rod is rotated in a forward direction at a speed substantially equal to that of the resin film, and a lower surface of the resin film is supported by a guide roll or a second coating rod placed on a downstream side of the first coating rod and an upstream side of a tenter so that the coating liquid continuously measured and supplied to an upper surface of the resin film is smoothened by the first coating rod.
Abstract:
A method of making catheters is disclosed in which the wall of the catheter has a porous structure for carrying additional agents, such as therapeutic or diagnostic agents. The method includes providing a core, applying a base polymer material and an inert material over the outer surface of the core, and consolidating the base polymer material to form a catheter having a porous polymer layer with the inert material contained within the pores thereof. The inert material can be applied with the base polymer material, or it can be applied in a separate step after the base polymer material has been partially consolidated to form the porous polymer layer. Additional agents can be mixed with the inert material before it is applied to the catheter, or such agents can be applied to the porous polymer layer of the catheter in a separate step after the inert material is removed therefrom.
Abstract:
The invention relates to a method for accelerated drying of at least one polymer which is located at least partially on a component, in particular at least a layer of paint and/or a sealing agent which is applied to an aircraft component in particular with a different material composition, involving the following steps of: a) at least partially applying the at least one polymer, in particular an epoxy resin and/or polyurethane-based layer of paint and/or a sealing agent, to an upper side of the component, and b) at least partially drying the polymer by means of electromagnetic radiation with a wavelength range of between 0.28 μm and 4.0 μm. Accelerated drying of the polymer, in particular the paint layer thereby becomes possible from an upper side of the component to an upper side of the paint layer, whereby high surface-quality of the painting can be achieved with processing times which are nonetheless short.Furthermore, the invention relates to a device for carrying out the method which allows particularly fully-automated implementation of the drying process with drying results which can at the same time be reproduced to a high degree.

Abstract:
The invention relates to a method for pre-treating fibre reinforced composite plastic materials prior to painting, wherein the materials are subjected to a low pressure cold vacuum gas plasma treatment without preheating the materials. The invention further relates to a method for applying a painting layer on a fibre reinforced composite plastic material, wherein the method comprises the steps of pre-treating the material using a method according to any one of the preceding claims, and subsequently applying the painting layer to the pre-treated material.
Abstract:
A printhead for an inkjet printer comprises a wafer assembly defining a plurality of spaced apart groups of ink supply channels and a plurality of groups of ink ejection nozzle arrangements. Each ink ejection nozzle arrangement comprises a nozzle chamber structure mounted to the wafer assembly. Each ink ejection nozzle arrangement further comprises an anchor extending from the wafer assembly in a location external to the nozzle chamber; and an elongate thermal actuator mechanism extending from the anchor and into the nozzle chamber. The thermal actuator mechanism comprises an elongate arm which terminates in a free end within the nozzle chamber, and a pair of layers of conductive material located on either side of the elongate arm. One of the layers is connected to a current supply for causing a differential thermal expansion in the elongate thermal actuator mechanism. A pit is defined adjacent each nozzle chamber structure for catching ink. The ink ejection nozzle arrangements of each group are arranged in a pair of rows, with the elongate thermal actuator mechanism of ink ejection nozzle arrangements of a first row extending away from those of ink ejection nozzle arrangements of a second row.

Abstract:
A method for manufacturing a color developing structure, includes: forming a first transparent thin film having a first refractive index with a first liquid material so that the first transparent thin film has a thickness determined based on predetermined color developing characteristics; forming a second transparent thin film having a second refractive index with a second liquid material so that the second transparent thin film has a thickness determined based on the predetermined color developing characteristics; and stacking the first transparent thin films and the second transparent thin films in layers by alternately repeating the forming of the first transparent thin film and the forming of the second transparent thin film multiple times so that the color developing structure having the predetermined color developing characteristics is obtained.
Abstract:
A hydrophobic foam insulation material is formed from a foam core material and a hydrophobic surface layer that is covalently bonded to the core, and is fully conformal to the core foam material. The surface layer is applied in a plasma. The foam material may have further been subjected to a reticulation process involving a plasma to reduce the density of the foam. Such hydrophobic insulation material is thus made lightweight, flexible, and suitable for aircraft applications.
Abstract:
A method of forming a vapor deposited film of a silicon oxide on the surface of a substrate by holding the substrate to be treated in a plasma-treating chamber, and effecting the treatment with a chemical plasma by feeding an organosilicon compound and an oxidizing gas into the treating chamber, wherein the rate of feeding the oxidizing gas is varied while maintaining constant the rate of feeding the organosilicon compound gas into the plasma-treating chamber during the formation of the vapor deposited film. A chemical vapor deposited film is formed featuring excellent adhesiveness, softness, flexibility, oxygen-barrier property and water-barrier property.
