A liquid material discharge device and method capable of suppressing generation of bubbles caused with a rod raising operation in a negative pressure environment. In a liquid material discharge device used in a negative pressure space and including a storage container; a compressed-gas supply source pressurizing the storage container; a nozzle having a discharge flow path; a reciprocating valve rod; an actuator driving the valve rod; a valve seat having a communication hole that is communicated with the discharge flow path; and a discharge control device controlling the actuator to open and close the communication hole by a tip of the valve rod, the discharge control device controls an acceleration time A.sub.u in rising of the valve rod by the actuator to be held within a range of 2 to 300 [ms], thus preventing generation of bubbles caused with the rising of the valve rod.

A fluid pressure-feed device includes a main tank and a sub tank. The sub tank is connected integrally with an upper portion of a main follower plate that applies pressurizing force to a urethane adhesive inside the main tank. A drum pump is provided in an upper portion of a sub follower plate provided in the sub tank. While the urethane adhesive is flowing into the sub tank from the main tank, the urethane adhesive is fed under pressure from the sub tank to a fluid passage by actuation of the drum pump. While the main tank is being replaced, the urethane adhesive inside the sub tank is fed under pressure to the fluid passage by the drum pump.

In one embodiment, a substrate treatment apparatus includes a mixer configured to mix a first liquid including a metal element and a second liquid being basicity to generate a third liquid including the metal element and being basicity. The apparatus further includes a supplier configured to supply the third liquid to a substrate. The apparatus further includes a first flow path configured to convey the third liquid from the mixer to the supplier not through a filter that removes particles from the third liquid.

Technical Problem Provide is a discharge device capable of easily controlling an operation of a plunger at the time of supplying a viscous material to a cylinder and a liquid supply method capable of forming a desired overlap portion. Solution to Problem The discharge device 10 includes the supply valve 40 which controls the supply of the viscous material M to the cylinder 30, the plunger 50 which applies a pressure to the viscous material supplied to the cylinder, the ball screw 60 which is movable in the same direction as the back-and-forth direction of the plunger, and the motor 120 which is connected to the ball screw through the power transmission mechanism 110, wherein the plunger and the ball screw are not connected.

A control system including a discharge control circuit configured to control an application device such that a coating is discharged from a discharge circuit; a robot control circuit configured to cause an articulated robot to change a position and an orientation of the discharge circuit such that the coating is applied to a workpiece; an application abnormality detection circuit configured to detect an abnormality in an application state of the coating on the basis of at least one of a state of the device or of the robot; an application position calculation circuit configured to calculate an application position of the coating; and an abnormality notification circuit configured to send a notification of a site of an abnormality in the application state on the workpiece on the basis of a detection result of the abnormality in the application state and a calculation result of the application position.

A distribution system for storing and conveying a supply of material is described. The distribution system includes a bin for storing and conveying a supply of material. The bin includes a housing defining an internal chamber configured to receive the material, at least one outlet configured to direct the material from the bin, a plate defining a lower end of the internal chamber and supporting and directing the material to the at least one outlet, an agitation device attached to the plate, and a gasket disposed between the plate and the housing.

The disclosure concerns a coating device for coating components with a coating agent, in particular for painting motor vehicle body components with a paint, with a printhead for applying the coating agent to the component, and with a coating agent supply for supplying the printhead with the coating agent to be applied, wherein the coating agent flows from the coating agent supply to the printhead at a specific coating agent pressure and a specific flow rate. The disclosure provides that the coating supply will control the coating agent pressure and/or the flow rate of the coating agent. Furthermore, the disclosure includes an associated operating method.

The purpose is to provide a discharge system which can minimize wear of a connecting part of a discharging device and a refilling device which is caused under the influence of particulate matters contained in fluid even if connection and disconnection for refilling the discharging device with the fluid is repeated. A discharge system includes a discharging device capable of discharging the fluid, and a refilling device capable of refilling the discharging device with the fluid. The fluid is suppliable from the refilling device side to the discharging device side by inserting one of a discharge-side coupler provided to the discharging device side and a refill-side coupler provided to the refilling device side into the other to connect the discharging device to the refilling device. A clearance size d formed between the discharge-side coupler and the refill-side coupler is determined based on the particle size distribution of the particulate matters that constitutes the fluid.
