A controller controls a plunger to operate at a measurement speed and discharge the viscous material from the nozzle before applying the viscous material to the workpiece. The controller measures a period of time, from when the plunger starts operating at the measurement speed until a discharge amount of the viscous material reaches a predetermined value, as a time delay amount. The controller further determines an operation speed of the plunger and/or a moving speed of the nozzle during application of the viscous material to the workpiece according to the measured time delay amount.

A method of delivering a glutinous substance from a cartridge to a brush comprises receiving the cartridge inside a sleeve through an inlet of the sleeve while a pressure cap, located proximate the inlet of the sleeve, is in an open position. The method also comprises moving the pressure cap, located proximate the inlet of the sleeve, into a closed position to sealingly couple the pressure cap with a trailing end of the cartridge and to sealingly couple a valve with a leading end of the cartridge. The method further comprises applying pressure to the glutinous substance in the cartridge through a pressure input of the pressure cap to urge the glutinous substance from the cartridge to the valve. The method additionally comprises rotating the brush and opening the valve to enable the glutinous substance to flow from the valve to the brush at least when the brush is rotating.

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.

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 fluid application device for applying a fluid to a surface and removing the same as necessary. The device may generally comprise a fluid applicator and a textile base member for sanitizing gym equipment, wiping windows, applying sunscreen, and the like. The fluid applicator may comprise a spray applicator, a permeable bladder, and the like. The textile base member may include but is not limited to a hand towel, a wristband, and any other known textile configurations. In one embodiment, the present invention may be used by gym patrons to sanitized gym equipment before and/or after use. The present invention may also be used to clean other surfaces including but not limited to household windows, vehicle windows, and the like. Additional embodiments of the present invention may also be used either to apply sunscreen on a user or as a fishing towel to clean hands and remove odor.

Disclosed is a substrate processing apparatus including: a processing chamber that accommodates a substrate; a light source that radiates energy rays for a processing to the substrate in the processing chamber; a rotation driving unit that rotates at least one of the substrate and the light source around an axis intersecting with the substrate in the processing chamber; an opening/closing mechanism that switches between an open state and a closed state; and a controller configured to control the opening/closing mechanism to switch between the open state and the closed state, to increase a light emission amount of the light source in synchronization with the switch of the open state to the closed state by the opening/closing mechanism, and to decrease the light emission amount of the light source in synchronization with the switch of the closed state to the open state by the opening/closing mechanism.

Methods, systems and apparatuses are disclosed for controlling the release of a coating material to a substrate surface, with the system and apparatuses emulating an experienced human artisan by sensing condition parameters and substrate parameters and comparing parameters to stored parameter values and value ranges.

A trigger assembly can be used to activate a motor controller to cause a motorized device to respond in a certain manner. For example, when the motorized device is a power tool, based on a number of pulls of the trigger, the motor controller can run the power tool in a forward direction or a reverse direction. A power tool running in the forward direction can receive a tap of the trigger. A timer can be started upon detecting the pull of the trigger. Another tap of the trigger can be detected within a time period determined based on the timer. The power tool can be forced to perform a reverse operation when the other tap f the trigger is within the time period.

An apparatus (100) for dispensing a flowable material (308) is disclosed. The apparatus (100) comprises a rotary actuator (120), a reservoir (140), containing a hydraulic fluid (155), a piston (145), movable inside the reservoir (140), a linear actuator (130), coupled to the piston (145), a gear train (125), coupling the rotary actuator (120) with the linear actuator (130), and a flowable-material dispenser (160), hydraulically coupled with the reservoir (140).

A defect may occur in which as the amount of fluid discharged by a fluid discharge device decreases, a mask is not filled with the fluid even when the fluid is discharged. In order to fill a workpiece with the fluid, it is necessary to replace air in the workpiece corresponding to a discharge part with the fluid. The air in the workpiece is removed in advance, thereby filling the workpiece with the discharged fluid. A fluid discharge device in which, at one end of a discharge head, a suction port for sucking air in the mask on the workpiece, and a fluid discharge device having a discharge nozzle formed thereon for discharging the fluid are formed is used.
