A method of detecting a defect in an applied volume of material includes detecting a pressure discontinuity during dispensing the volume of material along a predetermined path on a substrate. The pressure discontinuity is indicative of the defect in the applied volume of material. The location of the defect along the predetermined path is function of a start time of the pressure discontinuity and the size of the defect is a function of a time duration of the pressure discontinuity. The method can further include determining whether or not to repair the defect as a function of the location and the size of the defect in the applied volume of material. The method includes repairing the defect by re-directing the material applicator to the location of the defect and dispensing additional material at the location of the defect.

Provided are an adhesive application device and method used in the production of a laminated core, wherein the device and method are capable of stably applying an adhesive to a thin steel strip regardless of the transfer speed of the thin steel strip that is to be punched, and contribute to the improvement of the productivity of a laminated core.

A liquid material supply device includes a supply unit that supplies a liquid material, an opening and closing discharge unit that discharges the liquid material, a discharge flow path that is connected to the supply unit and the opening and closing discharge unit, a pressure adjustment unit that adjusts an internal pressure of the discharge flow path, a pressure feed device that delivers the liquid material to the opening and closing discharge unit through the discharge flow path, and a circulation unit that is provided between the supply unit and the opening and closing discharge unit to allow the liquid material to circulate into the discharge flow path through a circulation flow path which branches from the discharge flow path.

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.

Systems for creating electrodes for polymer electrolyte membrane fuel cells include an XY stage having a heated vacuum table physically coupled to the XY stage. The vacuum table has a working face with a plurality of channels formed therein to communicate vacuum pressure from a port coupled to a vacuum source to the channels. A sheet of perforated heat-conductive material has staggered holes configured to evenly distribute the vacuum pressure from the channels through the perforated sheet. A heat-conductive wire mesh is placed over the perforated sheet, and has openings smaller than the staggered holes such that a membrane material placed on the wire mesh is not deformed by the vacuum pressure. A nanopipette or micropipette coupled to a pump is configured to deposit electrode ink onto an exposed surface of the membrane material as the controller device causes the XY stage to move the vacuum table to control deposition of the electrode ink onto the surface of the membrane material.
