An ink-jet coater and a coating method for improving smoothness of a mixed part where the coating position in the previous scan overlaps the coating position in the next scan includes a robot arm configured to move a nozzle head unit by driving arms via an arm driving mechanism and a coating control unit configured to control driving of the nozzle driving mechanism and driving of the arm driving mechanism to execute coating on the coating object. The coating control unit performs coating by forming, in segmented coating surfaces formed by each scanning of the nozzle head unit, a normal coating region coated with a target coating film thickness and an overlapping coating region coated with a spray amount of the paint less than the normal coating region.

The present disclosure provides a painting robot and a painting method using the painting robot. The painting robot includes: an arm control unit which controls operation of the robot arm; a head control unit which controls driving of nozzles of the nozzle head; a distance measuring device which measures the distance between the painting portions and the nozzle discharging surface; and an image processing portion which forms a three-dimensional model for painting, which is a three-dimensional model, based on the painting coverage of the vehicle expected to be painted. The head control unit, based on the distances measured between the painting portions in the three-dimensional model for painting and an imaginary nozzle head or the distances measured by distance measuring device, controls to discharge paint from nozzles with distances within the prescribed range, and to not discharge paint from nozzles outside the prescribed range.

According to an embodiment of the present invention, a substrate processing apparatus including: a chamber in which a process is performed on a substrate; a susceptor installed in the chamber to support the substrate; and a showerhead installed above the susceptor, and the showerhead includes: a plurality of inner injection holes defined in an inner area corresponding to a portion above the substrate and injecting a reaction gas downward; and a plurality of outer injection holes defined in an outer area corresponding to a portion outside the inner area and injecting an inert gas along an inner wall of the chamber.

A pressure spray washer for cleaning gutters has a body having a curved outer surface. The body has an internal channel opening at one end of said body, and a plurality of orifices extending through the body so as to have one end opening to the internal channel and an opposite end opening at an exterior surface of the body. The body has a connector at one end of the internal channel, which is adapted to connect with a source of a pressurized fluid.

Pipe inspection systems including a push-cable, jetter, and camera assembly are disclosed. A jetter nozzle may be configured to spin and/or propel the camera head within a pipe or other cavity. A cutter line may be attached to the camera head to clean obstructions. A sonde may be coupled to a camera head to generate magnetic field signals for use with a buried utility locator to locate a pipe or other cavity into which the camera head is deployed.

The invention relates to nozzle tips including a nozzle body and a tip portion, configured to minimize the accumulation of a resin on the nozzle tip as it is dispensed through the nozzle tip. The nozzle tip can contain a central flow channel and an internal portion that branches and guides the resin into multiple exiting flow channels that define tangential pathways to the outer surface of the nozzle tip. The nozzle tip can include grooves that define extended, sharply angled flow paths for the resin. Nozzle tips can have a neck portion separating a nozzle body and a tip end of the nozzle tip; here, a doughnut-shaped space located around the neck portion can be defined by the base of the nozzle, the crown of the nozzle, and the neck portion, for encouraging turbulent flow of the resin to scour the nozzle tip during dispensing.

A coating device coats a to-be-coated object including a recessed portion extending in a first direction. The coating device includes a head, an arm, and a controller. The head includes a nozzle surface. The arm holds the head. The controller controls movement of the head via the arm. The controller moves the head in the first direction while causing the nozzle surface and the recessed portion to face each other in a posture in which a length of a first component along the first direction of the head is larger than a length of a second component of the head intersecting the first component.

A water floating-type light fountain includes a light-transmitting casing, a light-emitting assembly, and a water-spraying assembly. A mounting cavity is formed in the light-transmitting casing. The light-transmitting casing includes an upper casing and a bottom casing that are integrally formed. A band-shaped light-emitting surface is formed on an outer side surface of the upper case. The light-emitting assembly includes a circuit board, and a first light source and a second light source arranged on the circuit board. The first light source is located at the front of the circuit board, and the second light source is located at the back. The water-spraying assembly includes a spray head and a water pipe. The upper casing and the bottom casing are integrally formed, which effectively improves the waterproof performance of the light-transmitting casing, avoids water seepage, and saves the cost, and improves the landscape lighting effect of the light fountain.
