A method for coating objects starts with dispensing, by means of a first painting system, a first coating layer on a first object. A property of the first coating layer is measured to thereby obtain a first property value, and a coating variable of a second painting system is adjusted based on the first property value. A second coating layer is dispensed on the first coating layer by means of the second painting system which is different from the first painting system. By providing a measurement between the two painting systems, and by adjusting the coating parameters of the downstream painting system based on the measurement results, the overall coating can be corrected by compensating by means of the downstream painting system for a defective coating dispensed by the upstream painting system.

This invention relates to a method and system of applying a fluid material to a roofing surface. By modifying a peristaltic pump-driven sprayer device, a fluid material having a viscosity of 10,000 to 40,000 centipoise at 25° C. can be effectively sprayed onto a roofing surface. Additionally, the use of a modified peristaltic pump-driven sprayer device allows for the fluid material to be applied onto the roofing surface at a faster rate than other spraying methods.

The disclosure discloses a system for quality inspection in the entire process of inkjet printing manufacturing of display devices, which includes a substrate inspection module, a nozzle inspection module, an ink droplet inspection module, a coating thickness inspection module and a control module. Through design and matching of these modules, it is possible to realize a series of operations such as substrate inspection, nozzle inspection, flying ink droplet inspection, liquid coating inspection and cured coating inspection. The invention also discloses a corresponding quality inspection method for the entire inkjet printing manufacturing process for display devices. The invention effectively compensates for the shortcomings of current technology which only inspect a single stage without taking the whole process into consideration, thereby realizing high-precision quality inspection of each stage in the inkjet printing manufacturing process of display devices, and significantly improving the quality and yield of the display device product.

A method for fabricating a single electron transistor is provided. A substrate includes a substantially planar surface with a source electrode, a drain electrode, and a gate electrode thereon, with the source and drain electrodes spaced apart from one another by a gap. The source electrode and the drain electrode are electrified, and a single nanometer-scale conductive particle is electrospray deposited in the gap. The single nanometer-scale conductive particle has an effective size of not greater than 10 nanometers. At least one carbon nanotube is deposited on the substrate and subjected to dielectrophoresis to position the carbon nanotube within 1 nanometer of the single nanometer-scale conductive particle. The at least one carbon nanotube establishes a first connection between the source electrode and the single nanometer-scale conductive particle and a second connection between the drain electrode and the single nanometer-scale conductive particle.

Light can be used to monitor coating a liquid on a substrate. By directing the light to a spot on the substrate, when the liquid passes through the spot, some light will be reflected, while some light will be scattered. Monitoring this behavior can indicate whether a substrate has been successfully coated with the liquid, as well as identifying defects. Further, coating times can be monitored to make process adjustments.

A method of applying a coating product on a surface of a part, this method being carried out using an applicator including at least one row of nozzles, among which at least the first nozzle in the row includes a valve, the method including moving the applicator in a first direction to apply a first layer of coating product, and moving the applicator in a second direction substantially parallel to the first direction to apply a second layer of coating product adjacent to the first layer, comprising measuring at least one application distance of the first nozzle from a point in front of the first nozzle on a path of the applicator, and based on the measured application distance, opening or closing the valve.

The present application discloses a coating device including: a coating gun configured to apply a coating agent to an object; a sensor device configured to form a detection area in which the coating agent is detected on the object; a bracket on which the coating gun and the sensor device are mounted; and a robot configured to hold and rotate the bracket about a predetermined first axis of rotation. When the robot rotates the bracket from a first rotational position, at which the coating gun applies the coating agent to a coating position on the object, to a second rotational position in which the bracket is angularly changed by a predetermined rotational angle about the first axis of rotation, the detection area overlaps with the coating position.
