A viscous material wiping device wipes the viscous material attached to the tip of a spatula with a sheet. A sheet support jig has a groove recessed in the sheet facing surface, the groove includes a receiving portion and a wiping portion that are continuous in the groove extending direction, and the wiping portion has a groove width smaller than that of the receiving portion and substantially equal to the outer dimension of the tip of the spatula. A controller drives the moving mechanism to position the spatula on the opposite side of the sheet supporting jig with respect to the sheet in a posture that the spatula extends parallel to the groove extending direction and overlaps the groove when viewed in a normal direction of the sheet facing surface, and move the spatula in the normal direction so that the tip of the spatula is received in the receiving portion by pressing the sheet against the groove with the spatula. The spatula is configured to move in the groove extending direction so that the tip of the spatula passes through the wiping portion.

A coating apparatus of an airbag reinforcing liquid is used in a sewing machine that includes: a sewing needle driving an upper thread by penetrating sewing target cloth through a vertical movement; and a presser foot disposed above the sewing target cloth, and feeding the sewing target cloth while moving vertically synchronously with the vertical movement of the sewing needle. The coating apparatus includes: a reinforcing liquid supplying part, supplying a reinforcing liquid for reinforcing a sewn part onto the sewing target cloth on a front side from the sewing needle in a feeding direction of the sewing target cloth; and a stamp part attached to the presser foot, and expand the reinforcing liquid supplied from the reinforcing liquid supplying part onto the sewing target cloth around the sewn part by being operated integrally with the presser foot above the sewing target cloth.

A method for dispensing a flowable material is disclosed. The method comprises holding a hydraulic fluid in a reservoir at a negative pressure, inserting a cartridge tube, having an interior, into a cartridge housing, locking an over-center mechanism relative to the cartridge housing so that a hermetic seal is created between a plunger and an interior of the cartridge tube and between an end-cap and the interior of the cartridge tube, and turning a rotary actuator in a rotational direction so that a linear actuator advances a piston within the reservoir to transfer at least a portion of the hydraulic fluid from the reservoir to a flowable-material dispenser through the end-cap and into the interior of the cartridge tube, causing the plunger to advance within the cartridge tube in a forward plunger direction, away from the end-cap.

The present invention relates to an electrode slurry coating apparatus comprising a lower die applying electrode slurry on a collector, an intermediate die, and an upper die, a first discharge part primarily applying the electrode slurry on the collector to form a first coating layer; an intermediate pressing part pressing the first coating layer to adjust a thickness of the first coating layer; a second discharge part secondarily applying the electrode slurry on a surface of the first coating layer to form a second coating layer; and an upper pressing part pressing the first coating layer and the second coating layer, which are stacked, at the same time to to adjust a thickness of each of the first coating layer and the second coating layer, wherein the first discharge part has a width less than that of the second discharge part.

A dispensing apparatus is disclosed for dispensing fluid, such as liquid adhesive, from a fluid cartridge having a plunger movable between opposite ends within the cartridge. The dispensing apparatus is releasably coupled to a robot in order to control discharging of the fluid at a particular location. Movement of the plunger is carried out by a cartridge actuator assembly that includes a linear actuator, such as a servomotor, that moves a piston rod into engagement with the plunger such that the plunger can be movable under a force applied by the piston rod. A dispense section of the dispensing apparatus includes a valve assembly with a snuff-back mechanism that prevents excess dripping from an outlet of the dispenser. An end effector assembly may be coupled to the dispense section for dispensing the fluid to an application site in a precise and controlled manner.

A semiconductor processing apparatus according to the present embodiment is provided with a stage capable of placing a semiconductor substrate thereon and of rotating the semiconductor substrate. A plurality of holders are provided on the stage, to hold an edge of the semiconductor substrate. A plurality of sensors are provided to the plurality of holders, respectively, to detect the edge of the semiconductor substrate. An elevator mechanism is capable of changing heights of the holders. A controller controls the elevator mechanism to change the heights of the holders so that the plurality of sensors detect the edge of the semiconductor substrate.

A metering device is disclosed for regulating the depth of a flowable product coating a surface movable relative to the metering device by directing an air curtain towards the surface. The metering device comprises a body having an interior chamber, an inlet for connecting the chamber to a source of gas under super-ambient pressure; and an opening communicating with the chamber and having a mouth through which gas is discharged from the chamber towards the surface to form the air curtain. A porous or reticulated membrane is secured to, or formed integrally with, the body of the device to lie in the path of the gas discharged through the mouth of the opening.

The present invention is directed to a squeegee apparatus which includes a main housing including an inlet end and an outlet end, the outlet end including an extrusion face and a protruding lip member, the inlet end including an inlet opening and the extrusion face including at least one outlet opening, wherein the inlet opening and the at least one outlet opening are in fluid communication with each other within the main housing. The present invention is also directed to a method for repairing a thermal barrier coating with a squeegee apparatus including supplying a repair composition into the inlet opening of the squeegee apparatus and depositing the repair composition from the at least one outlet opening onto the damaged region and concurrently traversing the squeegee apparatus over the damaged region while contacting a thermal barrier coating adjacent to the damaged region with the lip member.

The embodiments of the disclosure disclose a doctor-bar adjusting mechanism for a coater, including: a base bracket, an upper plate and a lower plate secured to the base bracket at two ends thereof, a side of a doctor-bar sandwiched between the upper plate and the lower plate, and an other side of the doctor-bar close to a surface of a roller of the coater; the upper plate further comprising an adjusting plate on an upper side thereof, the adjusting plate secured to the base bracket at ends thereof and including a plurality of adjusting devices thereon adapted for adjusting a spacing between the adjusting plate and the upper plate. The implementation of the embodiments of the disclosure may adjust conveniently a spacing between the doctor-bar and the roller and improve the maintenance efficiency and productivity of the coater.
