The second pressure generating chamber is formed with an opening which is a discharge port. A mixture is discharged from the discharge port. A nozzle formed with an opening jets gas toward a substrate surface, and is provided in the vicinity of the discharge port of the ink head.
Abstract:
A method of using additional uplink measurements for MDT UL coverage is provided. A base station (eNodeB) establishes a radio resource control (RRC) connection with a user equipment (UE) in a mobile communication network. The eNodeB and the UE are configured for Minimization of Drive Test (MDT). The eNodeB receives a Power Headroom Report (PRH) corresponds to a Physical Uplink Shared Channel (PUSCH) from the UE, and forwards the PHR to an MDT server. The eNodeB performs uplink measurement of a Demodulation Reference Signal (DM-RS) allocated in the PUSCH. The uplink measurement also involves measuring an uplink Received Interference Power (RIP) associated with the PUSCH. The eNodeB then reports uplink measurement results to the MDT server. The MDT server is able to determine uplink coverage based on the PHR and the uplink measurement results.

An exemplary dosing device may include a screw pump or a spiral pump that is built into or onto the applicator, or into or onto a robot arm of the displacement machine.
Abstract:
A viscous material application apparatus includes a main body having a pressurized chamber which connects through to a discharge port and stores a viscous material, a viscous material supply device for transferring the viscous material to the pressurized chamber, and a discharge pressure regulating device for regulating the discharge pressure of the viscous material when the viscous material inside the pressurized chamber is pressurized and discharged by increasing or decreasing the capacity of the pressurized chamber, the discharge pressure regulating device being provided either inside the pressurized chamber or facing the pressurized chamber.
Abstract:
To provide a coating apparatus which is capable of making short a lag time up to action of a valve and making operate a discharging pump and a valve with the best timing. By employing electric-air regulators ER1 and ER2 of small size and high response speed as a speed controller for controlling a switching speed of a switching valve AV or a suck-back valve SV, total flowing course is made short, thereby a time lag up to operation of a valve is made short. Further, by detecting the pressure of a resist liquid being discharged from a discharging pump 120 by a pressure sensor 123, and by controlling the operation of each device of a discharging pump 120, a switching valve AV, and a suck-back valve SV through a controller 180, a discharging pump 120, a switching valve AV, and a suck-back valve SV can be operated with the best timings, and generation of particles due to dripping of a resist liquid at a tip end of a resist nozzle 60 is prevented from occurring.
Abstract:
The present invention provides a providing device capable of using a solution within a tank effectively than ever as preventing an air bubble from mixing in the solution to be provided to an applying device. In providing devices and for leading a coloring sensitive matter from any one of a plurality of pressure tanks to an applying device via a predetermined flow path, middle tanks are provided every for each of pressure tanks on the way of a flow path connecting each of the plurality of pressure tanks and the applying device. A sensor detects whether an amount of a solution stored in respective middle tanks is not less than a predetermined lower limit value or not. Then, a signal in response to its result of the detection is outputted to a system controlling device. On the basis of this output signal, it is discriminated whether the amount of the solution in the middle tank is not less than the lower limit value or not. Then, if it is detected that the amount of the solution in the middle tank is less than the lower limit value, the predetermined processing in association with the switching of the pressure tank is carried out.
Abstract:
The invention relates to a method of applying a multi-component glue mixture to objects passing through an applicator station for the application of said glue mixture in a manufacturing line. Waste glue mixture is produced during the application of said glue. The method comprises mixing glue components in a mixer to form said glue mixture. The waste glue mixture is collected in a tank, where it is mixed with a fresh glue component to form a mixture. The mixture of waste glue mixture and fresh component is returned to said mixer. A multi-component glue applicator machine (3) according to the invention comprises storage tanks (4, 6) for glue component, day tanks (17, 18) for said glue components, and mixing apparatus (38, 40, 42) for mixing glue components from said day tanks (17, 18) to form a glue mixture thereof. There is provided a glue applicator device (44). One of said day tanks (17) is provided beneath the glue applicator (44).
Abstract:
In order to obtain an optimal application of viscous material, such as an adhesive or a sealing agent. The process and apparatus combines the proportional metering device and the outlet valve to form a constructional unit. A static mixing tube is integrated into the filling opening. The feed pipe is partially tempered and therefore maintains the viscous material situated in the feed pipe at a constant temperature.
Abstract:
A photoresist dispense pump receives photoresist from two pipelines, a first pipeline and a second pipeline, and pumps out the photoresist through a third pipeline. The photoresist dispense pump contains a first bellows and a second bellows receiving photoresist from the second pipeline, wherein the first bellows and the second bellows are separated by a partition. Photoresist is fed into the third pipeline from the second bellows. On the center region of the partition, there is a central diaphragm that allows photoresist to flow in a direction from the first bellows toward the second bellows, but not in the reverse direction.
