The present invention provides a contacting type infiltration groove for photoresist coating equipment, comprises a loading main body and a sprinkler head. A spray nozzle is provided at the end of the sprinkler head, wherein, a limiting component is additional clamped at the end of the sprinkler head to make only the spray nozzle of the sprinkler head dip into the solvent in the loading main body. The sprinkler head can be hold up by the limiting component to separate the non-spray nozzle from the solvent so as to avoid the solvent contacting on the surface of the non-spray nozzle part. The contacting surface of the sprinkler head is setting on the top of the spray nozzle to make them adhere seamlessly together.

A method of contact coating at least one elastic strand with an adhesive is disclosed. A first strand has a periphery with an upper surface. The first strand is moved in a machine direction relative to a contact nozzle, the adhesive is discharged from the contact nozzle into contact with the upper surface of the first strand, and pressurized air is discharged at the adhesive on the first strand to cause the adhesive to spread around the periphery of the first strand without blowing adhesive off the first strand.

To provide a spout apparatus whereby expansion and deformation of the inner wall surface of the vortex generating portion such that a desired Karman vortex cannot be generated are prevented, even when the port portion is formed of an elastically deformable soft member. A spout apparatus for discharging hot or cold water with reciprocal motion, having a spout apparatus body and a vortex generating passage; whereby the oscillating element has a supply passage, a vortex generating passage, and a spout port passage, and the spout port passage is formed by an elastically deformable soft member, and is attached to the spout apparatus body so that a user can manipulate and deform the spout port passage, and the vortex generating passage is formed so as not to expand and deform even if internal pressure rises due to the supply of hot or cold water from the supply passage.

To provide a spout apparatus which is easily maintainable by a user even when, in a fluid device utilizing Karman vortices, scale adheres to the Karman vortex generating portion. A spout apparatus for discharging hot or cold water while causing it to reciprocally oscillate, having a spout apparatus body and an oscillating element; whereby the oscillating element has a water supply passage, a vortex generating passage, and a spout port passage; the spout port passage is formed of an elastically deformable soft member and is attached to the spout apparatus body so that a user can manipulate the spout port passage to deform it; and the vortex generating passage is formed of an elastically deformable soft member, and is integrally formed with the spout port passage so that deformations of the spout port passage can be transmitted to this vortex generating passage.

A cleaning device for atomizing and spraying liquid in two-phase flow comprising a nozzle provided with multiple liquid bypass pipelines each having liquid guiding outlets inclined at a predetermined angle and an exhaust mesh plate having vertical gas guiding outlets, which makes the high speed liquid flow and high speed gas flow sprayed out therefrom collide against each other sufficiently to form ultra-micro atomized particles with uniform and adjustable size. The ultra-micro atomized particles are sprayed out downwardly to the wafer surface under the acceleration and vertical orientation effects of an atomized particle guiding outlet to perform a reciprocating cleaning for the wafer. Other components such as an ultrasonic or megasonic generation unit, a gas shielding unit, a self-cleaning unit or a rotating unit can also be provided to perform the multifunction of the nozzle.

An automated system (100) for compounding pharmaceutical agents for injection treatment of a patient includes a housing (110) enclosing an interior space; an inventory structure (130) having a plurality of chambers (131) for individually holding one or more pharmaceutical agentcontaining single use capsules (102), wherein each capsule has a volume capacity of from about 0.1 to about 10.0 mL liquid; means (140) for selecting capsules in accordance with predetermined pharmaceutical agents contained in said capsules; means (150) for moving the selected capsules to a processing area; means (165,166) for sequentially transferring a controlled quantity of the predetermined pharmaceutical agent with direct fluid communication from each selected capsule to a product container under positive or negative pressure; and means (151) for automatically discarding spent capsules from which the pharmaceutical agents have been removed after a single use.

A spray tip comprises a tip body, a tip piece, and a pre-orifice piece. The tip body has a fluid channel along a channel axis (A.sub.C). The tip piece is disposed within the fluid channel, and has a stepped, narrowing passage that terminates in an outlet orifice. The pre-orifice piece has an inlet passage, and is disposed within the fluid channel, abutting and immediately upstream of the tip piece. The pre-orifice piece and the tip piece together define a turbulating chamber therebetween.

The invention relates to a device and a method for the metallic coating of a work piece with a mobile coating lance (20), by means of which a metal plasma jet can be generated to create the coating consisting of metal particles. According to the invention, an extraction hood (30) is provided, which at least encloses an axial section of the coating lance (20) in a ring-shaped manner, and the extraction hood (30) has a ring-shaped holding unit (50), which is configured to take up the metal particles.

Embodiments of the disclosed subject matter provide a nozzle assembly and method of making the same, the nozzle assembly including a first aperture formed on a first aperture plate to eject a carrier gas flow having organic vapor onto a substrate in a deposition chamber, second apertures formed on a second aperture plate disposed adjacent to the first aperture to form a vacuum aperture, where the first aperture plate and the second aperture plate are separated by a first separator plate, third apertures formed on a third aperture plate to eject purge gas that are disposed adjacent to the second aperture plate, where the second aperture plate and the third aperture plate are separated by second separator plate, and a third separator plate is disposed adjacent to the one or more third aperture plates to form a gas channel in the one or more third aperture plates.

A dispenser comprises a housing defining at least three feed channels, a spool valve with a spool defining at least three flow passages, a deformable sealing plug in at least two of the feed channels and in sealing orientation with both the housing and the spool, and a nipple in at least the two feed channels of the housing comprising sealing plugs; wherein the spool can reversibly rotate between an open orientation and a closed orientation can dispense two-component form formulations that are free of gaseous blowing agents.
