A step of constantly supplying first and second carrier gases into a processing container having a substrate therein through first and second carrier gas flow paths, respectively, and supplying a source gas into the processing container through a source gas flow path, a step of purging the source gas by supplying a purge gas into the processing container through a purge gas flow path provided separately from the carrier gas, a step of supplying a reactant gas into the processing container through a reactant gas flow path, and a step of purging the reactant gas by supplying a purge gas into the processing container through the purge gas flow path are performed in a predetermined cycle. An additive gas having a predetermined function is supplied as at least a part of the purge gas in at least one of the purging steps.

An electrostatic painting device capable of reducing any AC or electromagnetic emissions when the device is powered on is provided. The emissions affect electronic components present during painting of various objects or even when the device is powered on. The electromagnetic induction into the conductive circuit elements in turn induces voltages and currents, which potentially harm the micro-electronic circuits. One such device includes a choke between a fluid tip and a high voltage source of the device to reduce these emissions. The voltage source may include at least one capacitor which supplies the AC emissions representing electromagnetic emissions risk during the discharge of paint from the device. The choke connected to the voltage source substantially reduces the emissions involved during the paint discharge, while allowing the discharge of electrons, thereby imparting negative DC charge to the paint and the workpiece, and preventing damage to electronic circuits during the process.

Disclosed is a coating device which draws a pattern of a functional liquid on a substrate. The coating device includes: a substrate holding unit which holds the substrate; a droplet discharging unit which discharges a droplet of the functional liquid on the substrate held by the substrate holding unit; a moving unit which relatively moves the substrate holding unit and the droplet discharging unit in a main scanning direction and a sub scanning direction on a base; a mass measuring unit including a cup which receives the droplet discharged by the droplet discharging unit and a mass measuring device which measures a mass of the functional liquid accumulated in the cup; and a liquid drain unit which drains the functional liquid accumulated in the cup.

Systems and methods of applying self-seal strips of multiple different adhesives are disclosed. In one embodiment, two spaced apart spoked applicator wheel assemblies are positioned beneath a web of moving shingle stock such that each of the applicator wheels applies dots of different adhesives in an alternating pattern. In other embodiments, a layer of a second adhesive is deposited onto previously applied dots of a first adhesive to form layered adhesive dots with dual properties of both adhesives.

Protective coatings with one or more additives dispersed therethrough are disclosed. A protective coating may comprise a poly(p-xylylene), or parylene. An additive may be configured to cause the protective coating to contrast (e.g., visibly, etc.) with features or components that are exposed beyond a periphery of the protective coating. Additives that provide other characteristics are also disclosed. In addition, methods for applying protective coatings according to this disclosure are disclosed, as are inspection methods.

The invention is directed towards methods and compositions for treating piles of particulate materials to inhibit and prevent the loss of valuable fuel or mineral dust from being released from storage piles or open containers. The method involves applying separately to the pile two different compositions. When separate the two compositions are low viscosity and easy to spray. When combined the two form a gel coating that is resistant to erosion but is flexible while the pile or payload is still settling, jostling, being bumped, and otherwise moving around. This coating is especially effective for coal piles, iron ore piles, and also for piles within and/or being moved by open topped railroad cars. The coating's flexibility prevents the coating from becoming brittle and shattering. The coating has better performance than its ingredients do alone. As a result the invention can both prevent unwanted dust pollution as well as save its users money by avoiding loss of blown away material.
