A device for measuring and regulating a volume of a fluid dispensed by a time-pressure dispenser, the device comprising: an adaptor for releasably coupling a syringe to the device, the syringe containing a fluid to be dispensed; a probe configured to be coupled with a piston of the syringe, the piston being operative to apply a pressure for ejecting the fluid from the syringe upon the application of an air pressure to the piston; and a displacement detector operative in use to determine a position of the probe so as to determine a position of the piston when dispensing the fluid, whereby to regulate the volume of the fluid dispensed from the syringe.

A film forming apparatus is disclosed. The apparatus comprises a chamber; an exhaust unit configured to reduce the pressure in the chamber to a predetermined vacuum level; a holder disposed in the chamber and configured to hold a film forming target member on which a film is to be formed; a supply unit configured to supply a film forming material containing silicon to a surface of the film forming target member; and a heat source configured to perform heating at the predetermined vacuum level to melt the supplied film forming material.

A method for metering a liquid or pasty product in a pressure-regulated manner, has the following steps: metering the product into a mixing chamber using a metering pump; ascertaining a product pressure of the product according to the mixing chamber; ascertaining a deviation of the product pressure from a specified target pressure; and opening or closing a pressure regulating valve provided on an outlet nozzle of the mixing chamber based on the pressure in order to equalize the product pressure and the target pressure, wherein the product pressure is reduced when the pressure regulating valve is opened and increased when the pressure regulating valve is closed.

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.

A piston includes: a base body; a sealing ring provided at an outer peripheral surface of the base body and configured to slidingly contact an inner peripheral surface of a container; a pressing body provided at one side of the base body in a non-hermetical state with respect to the container, the one side being close to a fluid; and a supporting member supporting the pressing body in a state where the pressing body is separated from the base body. The base body includes an air discharge hole through which an inside and outside of the container communicate with each other, the inside and outside of the container being sealed by the sealing ring. The pressing body can approach and separate from the base body between a first position at which the pressing body opens the air discharge hole and a second position at which the pressing body closes the air discharge hole. The pressing body is supported by the supporting member at the first position and moves to the second position by force applied from the fluid in the container.

A hot melt adhesive system includes an adhesive supply for receiving solid or semi-solid hot melt adhesive, and a heater associated with the adhesive supply for melting the solid or semi-solid hot melt adhesive into liquid hot melt adhesive. An adhesive tracking system monitors an output of the liquid hot melt adhesive, and includes a flow meter having a flow inlet and a flow outlet. The flow meter measures an amount of the adhesive flowing out of the flow outlet. A product detector may be used to sense a presence of a product to which the adhesive is applied. A controller then determines the total amount of the liquid adhesive dispensed and the average amount of liquid adhesive dispensed per product.

A treatment solution supply apparatus supplies a treatment solution to a solution treatment apparatus which applies the treatment solution to a substrate to perform a predetermined treatment. Plural solution treatment apparatuses are supply destinations of the treatment solution. The treatment solution supply apparatus includes: a sending unit common among the solution treatment apparatuses, the sending unit sends the treatment solution stored in a treatment solution supply source to each of the solution treatment apparatuses; and a control unit that controls the sending unit. The sending unit includes pumps that suck the treatment solution and load the treatment solution thereinto and send the loaded treatment solution. The control unit controls suction timing of each of the pumps so that one (or more) of the pumps becomes in a state capable of sending the treatment solution to the solution treatment apparatuses at all times.

The present invention refers to a flow measuring system and, more particularly, to a flow measuring system adapted for measuring a flow rate of sealant applied to a plurality of parts, the flow measuring system having a plurality of flowmeters, each of the flowmeters in fluid communication with a fluid injector, and the plurality of flowmeters being configured to generate, process and transmit a signal related to the flow rate of the injected fluid.

A sealant discharging apparatus includes a sealing gun, a movement controller, a discharge controller, a measuring instrument, and an air bubble detector. The sealing gun is configured to discharge sealant to an object. The movement controller is configured to cause the sealing gun and the object to move relatively. The discharge controller is configured to control a discharge amount of the sealant discharged from the sealing gun. The measuring instrument is configured to measure a distance to a sealant pool that has been discharged from the sealing gun and yet to be used to seal the object. The air bubble detector is configured detect mixture of an air bubble in the sealant discharged from the sealing gun, on a basis of a result of measurement by the measuring instrument.

An application method configured to apply an adhesive to an object comprises applying, prior to applying the adhesive to a specified part of the object, the adhesive to a part different from the specified part, calculating an application quantity of the adhesive applied to the part different from the specified part, making a first correction configured to correct an application condition of the adhesive on the basis of a result of the calculation, and applying the adhesive to the specified part on the application condition corrected in the first correction.
