A needle-less injector device for delivering a dose of fluid intradermally, subcutaneously or intramuscularly to an animal or human. The device includes an inner housing having opposed ends. A syringe is disposed in one end of the inner housing. The syringe includes a nozzle for delivering a dose of fluid held within the syringe. A plunger is movably disposed within the syringe. A spring powered hammer is movably disposed within the inner housing. The hammer cooperates with the plunger to drive the dose of medicament from the nozzle. An injection delivery spring for powering the hammer is positioned and compressed between the other end of the inner housing and the spring powered hammer. An outer housing slideably supports the inner housing. A skin tensioning spring is mounted between the inner housing and the outer housing, the skin tensioning spring biasing the nozzle of the syringe against the animal or human. A trigger mechanism is disposed in the outer housing, the trigger mechanism cooperating with the spring powered hammer to release the injection delivery spring, wherein the size of the injection delivery spring and the length of the hammer dictate the amount of dose delivered and whether the dose is delivered intradermally, subcutaneously or intramuscularly to an animal or human.

A vacuum breaker arrangement for use with a container includes body parts holding a resilient valve member captive. The valve member includes an intermediate body part, intermediate and enlarged head and a valve part. The valve part is made of resilient material which defines an internal passageway communicating with an opening in the body parts. The valve part includes an end portion defining a slit which is closed at a first pressure and which is automatically opened at a second, reduced pressure.

An etching chamber 1 incorporates a focus ring 9 so as to surround a semiconductor wafer W provided on a lower electrode 4. The plasma processor is provided with an electric potential control DC power supply 33 to control the electric potential of this focus ring 9, and so constituted that the lower electrode 4 is supplied with a DC voltage of, e.g., −400 to −600 V to control the electric potential of the focus ring 9. This constitution prevents surface arcing from developing along the surface of a substrate to be processed.

The present invention relates to packaging combination for accommodating and dispensing a viscous or granular filling material. The packaging combination comprises a tubular casing having a first end and a second end, wherein the tubular casing is closed at its first as well as its second end by a closure means. The packaging combination further comprises a dispensing device having a passageway extending through the dispensing device with an inlet opening at its one end and a dispensing opening at its other end for guiding and dispensing the filling material in a dispensing direction, and being attached to the first end closed tubular casing.
