A sealant applicator for spreading caulk material along a surface of a structure. The sealant applicator has an attachment base with a channel through which the tapered nozzle of the sealant tube extends. The sealant applicator also has an application blade that extends from the upper surface of the attachment base. The application blade has a triangular-shaped blade with a distal tip and opposed lateral wings, for spreading caulk material that is dispensed from the tapered nozzle, along a surface of a structure, to cover and seal joints and crevices in the surface of a structure.

There is provided an apparatus for forming a magnetic pigment pattern on an article. The apparatus includes: a magnetic pattern mold having nonmagnetic pattern grooves engraved in a predetermined pattern and providing predetermined magnetic field lines on a pattern-forming object surface of an article by generating magnetism in areas outside the nonmagnetic pattern grooves; and a spray unit spraying an adhesive resin composite containing a ferromagnetic pigment onto the pattern-forming object surface of the article. A predetermined magnetic pigment pattern is formed while the magnetic pigment of the adhesive resin composite that is applied to the pattern-forming object surface of the article is rearranged along magnetic field lines generated by the magnetic pattern mold.

There is disclosed a method of printing onto the surface of a substrate, which method comprises i) coating a donor surface with a monolayer of particles, ii) treating the substrate surface to render at least selected regions tacky, and iii) contacting the substrate surface with the donor surface to cause particles to transfer from the donor surface only to the tacky regions of the substrate surface. After printing on a substrate, the donor surface returns to the coating station where the continuity of the monolayer is restored by recovering with fresh particles the regions of the donor surface exposed by the transfer of particles to the substrate.

A substrate processing apparatus according to an aspect of the present disclosure includes a substrate holder, a top plate portion, a gas supply unit, and an arm. The substrate holder holds a substrate. The top plate is installed to face the substrate held on the substrate holder, and has a through hole formed therethrough at a position facing the center of the substrate. The gas supply supplies an atmosphere adjustment gas to a space between the substrate holder and the top plate. The processing liquid nozzle ejects a liquid to the substrate. The arm holds the processing liquid nozzle and moves the processing liquid nozzle between a processing position where the processing liquid is ejected from the processing liquid nozzle through the through hole and a standby position outside the substrate.

An apparatus is disclosed for coating a surface that is movable relative to the apparatus with a layer of metallic particles or particles having a metal-like appearance and reflectivity, the particles adhering more strongly to the surface than to one another. The apparatus comprises at least one spray head for directly or indirectly applying to the surface a fluid stream within which the particles are suspended, a housing surrounding the spray head(s) and defining an interior plenum for confining the fluid stream, the housing having a rim adjacent the surface that is configured to prevent egress of particles from a sealing gap defined between the rim of the housing and the surface to be coated, and a suction source connected to the housing to extract from the plenum the sprayed fluid and particles suspended in the sprayed fluid. In operation, the suction source extracts substantially all particles that are not in direct contact with the surface, so as to leave only a substantially single particle layer adhering to the surface on exiting the apparatus.

The coating device has a rotatable spindle which has fastening mechanisms for fastening a rotation axle to the spindle. Protrusions are radially protruding from the spindle for spreading the coating substance on the inner surface of a pipe. The protrusions have limiters that limit the coating substance to be spread to the desired layer thickness. The method comprises the steps of bringing, to the pipe to be treated, the coating device fastened to a rotation axle with the pipe, a feeding hose of the coating substance and a camera. The coating substance is fed along the feeding hose to a vicinity of the coating device. The coating substance is spread to an inner surface of the pipe by rotating the coating device and by moving the coating device in a longitudinal direction of the pipe.

The embodiments of the disclosure disclose a doctor-bar adjusting mechanism for a coater, including: a base bracket, an upper plate and a lower plate secured to the base bracket at two ends thereof, a side of a doctor-bar sandwiched between the upper plate and the lower plate, and an other side of the doctor-bar close to a surface of a roller of the coater; the upper plate further comprising an adjusting plate on an upper side thereof, the adjusting plate secured to the base bracket at ends thereof and including a plurality of adjusting devices thereon adapted for adjusting a spacing between the adjusting plate and the upper plate. The implementation of the embodiments of the disclosure may adjust conveniently a spacing between the doctor-bar and the roller and improve the maintenance efficiency and productivity of the coater.

Disclosed is a method for washing a smearing member, the method including: dropping a washing agent on a glass slide; and causing the smearing member to be in contact with the washing agent on the glass slide, to wash the smearing member.

An additive manufacturing device includes a recoater configured to push powder onto a build platform. The recoater defines an advancing direction for pushing powder. A first baffle is mounted to a first end of a leading edge of the recoater and a second baffle mounted to a second end of the leading edge of the recoater opposite the first end. Each of the first and second baffles includes a base mounted to the recoater, a first wall that extends obliquely ahead of and laterally outward from the base relative to the advancing direction, and a second wall opposite the first wall. The second wall extends obliquely ahead of and laterally inward from the base relative to the advancing direction. A volume is defined between the first and second wall with capacity to collect powder as the recoater advances.
