Abstract:
The present invention provides a process for preparing a thin film having alternating monolayers of a metal-metal bonded complex monolayer and an organic monolayer by layer-by-layer growth. The process comprises the steps of: (1) applying onto a surface of a substrate a first linker compound to produce a primer layer; (2) applying onto said primer layer a layer of a metal-metal bonded complex to produce a metal-metal bonded complex monolayer on said primer layer; (3) applying onto said metal-metal bonded complex monolayer a second linker compound; and optionally (4) sequentially repeating steps (2) and (3) at least once to produce said layer-by-layer grown thin film having alternating monolayers of a metal-metal bonded complex monolayer and an organic monolayer.
Abstract:
A method for non-conformally coating nanometer-sized surface structures includes directing the overcoat material at an oblique angle onto a substrate having a nanometer-sized surface structure so that the overcoat material is only deposited substantially on the top portions of the nanometer-sized surface structures without filling the gaps between the nanometer-sized surface structures. Because the overcoat material is deposited onto the nanometer-sized surface structures obliquely, the overcoat material gradually closes the gaps between the nanometer-sized surface structures and form a continuous layer over the nanometer-sized surface structures.

A fine patterning and fine solid via process with printing method for multi-layer substrate, which including the following steps, providing a substrate which is completed from the pre-process; placing a dielectric layer on at least one surface of the substrate; defining via and circuit on the dielectric layer with the laser ablation; printing the surface of the dielectric layer with sub-micro conductive paste and stuffing said via and circuit on the dielectric layer to form complete via and circuit structure. Finally, proceeding the planarization process on the conductive paste placed on the surface of the substrate to form the complete conductive circuit and via structure at the same time.
Abstract:
The present invention is a method and device, which is suitable for use in an operating theater just prior to implantation, for selectively applying a medical coating to an implantable medical device, for example a stent. Disclosed is a device for use with a stent deployed on a catheter balloon. The device is configured to apply a medical coating of a desired thickness to the surface of a stent only. This is done by use of a drop-on-demand ink-jet printing system in association with an optical scanning device. The device is further configured so as to, if necessary, apply a plurality of layered coats, each layered coat being of a different coating material, and if appropriate, different thickness. The section of the housing in which the stent is held during the coating procedure is detachable from the housing base. The detachable housing section may be easily cleaned and re-sterilized or simply disposed of.

A method of treating a metal substrate by applying a coating of a silane composition having at least one substantially unhydrolyzed aminosilane having one or more secondary or tertiary amino groups. Methods of adhering a polymer (such as rubber) to a metal substrate are also provided.
Abstract:
An electroless or electrolytic process for treating metallic surfaces is disclosed. The disclosed process exposes the metallic surface to a first medium comprising at least one silicate, and then to a second medium comprising colloidal silica (additional processing steps can be employed before, between and after exposure to the first and second mediums). The first and second mediums can be electrolytic or electroless.
Abstract:
Sequentially carried out are: a sealing-agent applying step of applying a sealing agent to a predetermined portion of a vehicle body; a coating step of applying a coating material to the vehicle body after the sealing-agent applying step; and a baking step of baking the coating material to the vehicle body after the coating step. Further, a sealing-agent drying step of drying the sealing agent by heating only the predetermined portion of the vehicle body is carried out between the sealing-agent applying step and the coating step. Thus, the sealing agent applied partially to the vehicle body can be dried with a high thermal efficiency in the process of forming a coating on the vehicle body.
Abstract:
A low-emissivity multilayer coating includes, in order outward from the substrate, a first layer including a layer containing titanium oxide, a layer containing silicon nitride, or a sublayer layer containing titanium oxide in combination with a sublayer containing silicon nitride; a second layer including Ag; a third layer including at least one layer selected from titanium oxide layers and silicon nitride layers; a fourth layer including Ag; and a fifth layer including silicon nitride. The color of the coatings can be varied over a wide range by controlling the thicknesses of the layers of titanium oxide, silicon nitride and Ag. A diffusion barrier of oxidized metal protects relatively thin, high electrical conductivity, pinhole free Ag films grown preferentially on zinc oxide substrates. Oxygen and/or nitrogen in the Ag films improves the thermal and mechanical stability of the Ag. Dividing the first layer of titanium oxide, the Ag layers, and/or the third layer with a sublayer of oxidized metal can provide greater thermal and mechanical stability to the respective layers.
Abstract:
The present invention provides a method for forming a desired plating film on a desired place at a reasonable cost. When workpieces are mixed in a plating solution containing Ni ions with a great number of Zn particles having an average diameter of 1 mm and having an electrochemically base immersion potential with respect to the precipitation potential of Ni, the Zn particles are dissolved and generates electrons, the potential of Cu electrodes in contact with the Zn particles is shifted to an electrochemically base potential side, and hence the Ni ions are precipitated on the electrodes, thereby forming Ni plating films on the surfaces of the electrodes. In a manner equivalent to the above, when Zn particles are immersed in a plating solution containing Sn ions, the Zn particles are dissolved and generates electrons, the potential of the Ni plating films in contact with the Zn particles is shifted to an electrochemically base potential side, and hence the Sn ions are precipitated on the Ni plating films, thereby forming Sn plating films.
Abstract:
A degassed polyester varnish is applied to the transduction driver to increase surface dielectric strength (insulation resistance), driver voltage breakdown, physical protection, and heat and water resistance. A vacuum chamber application process is used to apply the polyester varnish. The disclosed coating technique is applicable to all transducer drive materials and all transducer types.
