Abstract:
Method for production of deposit or layer of nanoparticles or a layer of nanofibers from solutions or melts of polymers in electrostatic field of a high intensity, during which the produced nanoparticles or the produced nanofibers deposit on a substrate material passing through the active chamber, in which is positioned the active electrode. The electrostatic field for production, transfer and depositing of nanoparticles or production, transfer and depositing of nanofibers is induced between the active electrode and the substrate material, on which in the direction of its movement in front of and/or opposite to the active electrode there is applied an electric charge of opposite polarity than that of the active electrode, while an electric charge applied on the substrate material is being partially or totally consumed through depositing of nanoparticles or nanofibers on the moving substrate material.
Abstract:
A method of manufacturing a floor board comprises the steps of supplying a panel, printing a curable substance or surface removing substance onto the panel in a predefined pattern for creating an elevation on the panel at the pattern or removing a portion of the surface of the panel at the pattern, respectively, and curing the curable substance or removing any re-action products of the surface removing substance and the panel.
Abstract:
A method of formulating ink for high-speeding printing includes controlling a surface tension of the ink to equal to or greater than 26 mN/m, equal to or greater than 28 mN/m, or equal to or greater than 30 mN/m. The surface tension is measured when the ratio of the total non-volatiles volume fraction of the ink to the maximum total non-volatiles volume fraction of the ink is a ratio between about 0.40 and about 0.90. An ink for high-speed printing includes one or more resins, one or more colorants, one or more solvents, and one or more additives. The ink can be a flexographic ink, a rotogravure ink, a heatset offset ink, or a publication gravure ink. A print of the ink includes less than 1% of pinholes by area. A method of printing includes preparing an ink and applying the ink to a substrate. The ink has a surface tension of equal to or greater than 26 mN/m, and the substrate moves at a speed of greater than 1200 feet/min.
Abstract:
Methods for coating medical devices for implantation within a body vessel are provided comprising providing a cylindrical container, placing a medical device inside the cylindrical container, and applying a polymer in liquid form inside the container.
Abstract:
A bar coater includes: a bar for applying a coating liquid to a web; a support member which is arranged on a lower side of the bar so as to rotatably support the bar; a weir arranged at an upstream side of the bar, the weir having a leading end surface at its distal end portion to form a bead of the coating liquid in a space between the leading end surface and the web; a reservoir including the bar, the support member and the weir, the reservoir for accumulating the coating liquid; a pump for supplying the coating liquid to the reservoir; a liquid discharge passage through which the coating liquid excessively supplied to the reservoir is discharged; and a controlling device for controlling the pump so as not to cause distortion of a dynamic contact line which is formed at interface between the coating liquid and the atmosphere.
Abstract:
Coating rollers accepting liquid media provide liquid chemicals to substrates for depositing a thin coating layer on the flat substrates, such as semiconductors or panels. The liquid media is cooled to a life-preserving temperature while shielded from the thermal energy heating the substrates to prevent degrading the liquid media. Physical barrier or temperature barrier can be established in vicinities of the rollers to further limit exposing the liquid media to high temperature.
Abstract:
A method for applying a fluid onto a substrate. The fluid, upon exiting a container, passes through a porous material that is in contact with the substrate, and the porous material is provided with a marking agent that marks the application site of the fluid on the substrate.
Abstract:
A method of coating a microneedle array by applying a coating fluid using a flexible film in a brush-like manner. A method of coating a microneedle array comprising: providing a microneedle array having a substrate and a plurality of microneedles; providing a flexible film; providing a coating solution comprising a carrier fluid and a coating material; applying the coating solution onto a first major surface of the flexible film; performing a transfer step of bringing the first major surface of the flexible film into contact with the microneedles and removing the flexible film from contact with the microneedles; and allowing the carrier fluid to evaporate.
Abstract:
A method for coloring a recognizable tool bit comprises: positioning step: a tool bit positioned on a rotating means; setting step: adjusting a flow rate of a daubing means for deciding a thickness of a colored layer of the tool bit; daubing step: the daubing means having a brush to paint the tool bit, the rotating mechanism rotating the tool bit for annularly coloring on an outer periphery of the tool bit; execution step: an operator only pedaling a pedal-typed switch to start or to stop coloring the tool bit such that the operator can further use two hands to position the next tool bit or to collect finished tool bits sequentially; removing step: detaching the colored tool bit from the rotating means.
