Object: A liquid material application apparatus and a liquid material application method are provided with which a liquid material can be discharged in a predetermined discharge amount per unit time regardless of a relative moving speed in a series of application works.

Solution: The liquid material application apparatus includes a discharge head, a robot moving the discharge head relative to a workpiece, a movement control unit controlling relative movement of the discharge head and the workpiece, and a discharge control unit controlling an operation of discharging a liquid material from a discharge head, wherein the discharge control unit executes, in a switchable manner in accordance with an application program, first mode discharge control of changing a discharge amount of the liquid material, which is discharged from the discharge head per unit time, depending on a relative moving speed between the discharge head and the workpiece, and second mode discharge control of operating the discharge head to discharge the liquid material in a predetermined discharge amount per unit time regardless of the relative moving speed. The liquid material application method is implemented using the liquid material application apparatus.

When a portion for measuring the plating adhesion amount reaches an upstream side position, plating adhesion amount estimation values are calculated by using a plating adhesion amount estimation expression at positions away from a position that faces the distance sensors, that is, the upstream side position, by strip-width direction distances, of the surfaces of the steel strip. When the portion for measuring the plating adhesion amount reaches a downstream side position, the strip-width direction distances of the plating adhesion amount meters are matched to the strip-width direction distances, and the plating adhesion amount actual measurement values are obtained. The plating adhesion amount estimation expression is corrected on the basis of the differences between the plating adhesion amount estimation values and the plating adhesion amount actual measurement values. Accordingly, the control accuracy of the plating adhesion amount is improved.

A method of applying a marking onto a metrological scale. The method includes locating one or more markings on the scale substrate in a provisional state; checking whether the one or more markings located on the scale substrate are acceptable; and finalizing the one or markings which are acceptable so as to transform the one or more markings into a finalized state.

A method for controlling an ejector is disclosed, wherein the ejector comprises an actuator arrangement configured to eject a droplet of viscous medium onto a substrate, and wherein the droplet forms part of a sequence of a plurality of droplets. The method comprises obtaining a control parameter for controlling the operation of the actuator arrangement, and operating the actuator arrangement, using the control parameter, in order to eject the droplet. The obtained control parameter is based on at least one of: a time period between the droplet and a previous droplet in the sequence, a difference in target size of the droplet and a size of the previous droplet in the sequence, and the droplets position in the sequence.

Systems for producing, applying and evaluating coating compositions are disclosed. An automatic color matching system includes an automatic coating component dispenser, a container, a mixer for mixing the components of the coating composition and a solvent, an automatic pressurization station to apply pressure to the mixed coating composition, and a robotic arm to transport the container to and from the mixer.

The present disclosure is a sheet producing device for producing a multi-layer sheet by applying a coating material to a sheet material. The sheet producing device includes a radiation light source that emits radiation light, a division part that divides the radiation light into measurement light to be incident on the multi-layer sheet and reference light with which a reference surface is to be irradiated, and an optical member that emits the measurement light onto the multi-layer sheet and receives the measurement light reflected by the multi-layer sheet.
