Provided is a spray nozzle that makes it possible to reduce a difference in film thickness in a film. A spray nozzle (1) for use in a cold spray device (100) includes: a nozzle main body (15) that has a first path (20) through which a film material and a carrier gas pass; and a nozzle tip section (16) that is provided at a tip section of the nozzle main body (15) and has a second path (21) which communicates with the first path (20), the second path (21) being broadened at a position apart from a cross-sectional center (P) of the second path (21).

A deposition apparatus includes: discharge nozzles arranged at predetermined intervals in a processing compartment in a deposition chamber, wherein each of the discharge nozzles comprises a discharge port that discharges aerosolized particulates toward a corresponding surface treatment object; linear motor single-axis robots arranged at predetermined intervals in a direction perpendicular to a nozzle arrangement direction; and nozzle head units that each adjust a mutual distance between the discharge port and a surface of the corresponding surface treatment object based on a shape of the corresponding surface treatment object, the nozzle head units moving along the nozzle arrangement direction, and the nozzle head units being arranged in each of the linear motor single-axis robots.

A medicine powder delivery device and a medicine bottle thereof and a bottle cap of the medicine bottle are disclosed. The medicine powder delivery device includes a medicine bottle and a gas supply member. The medicine bottle has a bottle body and a bottle cap. The bottle body is filled with a medicine powder. When the bottle body is inverted, the bottle body has an unfilled space that is not filled with the medicine powder. The bottle cap includes a cap body, a medicine delivery tube, and a gas delivery tube. The cap body covers the bottle body. The medicine delivery tube and the gas delivery tube extends into the cap body. The medicine delivery tube communicating with the bottle body the gas delivery tube inserted into the unfilled space of the bottle body. The gas supply member is connected to the gas delivery tube.

Tunable multi-layer thermoplastic polymer sealants and tunable two-layer conductive thermoplastic polymer sealants, and substrates and assemblies comprising the tunable multi-layer sealants; and edge seals and fillet seals produced comprising such sealants; and substrates, components and objects comprising the tunable edge seals and fillet seals, and methods for making and applying such edge seals and fillet seals are disclosed.

The invention provides a pneumatic conveying system having a series of supply lines with at least portions of the lines being wear resistant to extend the useful lifespan of an agricultural product delivery applicator. The wear resistant supply line(s) may be made from a hard material and have a curve(s) defined by angled or mitered segments that are welded or otherwise joined to collectively provide the curve(s) The wear resistant supply lines may be at least partially reinforced by way of, for example, welded or other build up wear resistant material(s) at high wear zones of the supply lines.

Disclosed is a cold spray gun and a cold spray apparatus using the same capable of stably heating a raw material powder to a specific high temperature with an achievement of compactness and lightweight of the apparatus. In order to achieve the above described object, there is provided a cold spray gun configured to form a coating film by spraying a raw material powder carried on a carrier gas from a nozzle outlet by a supersonic flow together with a working gas heated to a temperature equal to or lower than a melting point or a softening point of the raw material powder, and causing the raw material powder to collide with a base material in a solid state, the cold spray gun including; a chamber containing the working gas to be delivered to the nozzle; and is characterized in that a gas heating pipe constituted from a heating resistor which causes resistance heating by being energized is arranged in the chamber, and the working gas flowing into the interior of the gas heating pipe is heated.

A powdery-material mixing and feeding system is configured to feed a machine configured to execute a post process with mixed-powdery materials obtained by mixing a first powdery material and a second powdery material discharged from powdery-material feeding devices at a required ratio, wherein when a flow rate of the first powdery material discharged from the first powdery-material feeding device departs from a target value by a predetermined amount or more, a controller increases or decreases the flow rate of the second powdery material discharged from the second powdery-material feeding device such that the ratio of the first powdery material to the second powdery material contained in the mixed-powdery materials is kept within a desired range.
