A dispensing cartridge for a relatively precise dispensing of various fluids having a relatively wide range of viscosities is disclosed. The dispensing cartridge in accordance with the present invention is relatively simpler in configuration than known dispensing cartridges while minimizing leakage of the fluid and eliminating problems associated with chemical attack of the O-ring by the fluid in the dispensing cylinder. In particular, the dispensing cartridge in accordance with the present invention includes a cylinder; a piston with a central bore and a bleed plug. In order to simplify the design, the air vent is configured as a tortuous path, for example, a spiral path, defined by a spiral bleed plug, which in a pre-staged position, allows air to freely escape along the spiral path along the circumference of the plug. As the piston contacts the fluid, the forward motion of piston is resisted by the high back pressure created by the small effective diameter and relatively long length of the spiral path. Once the piston contacts the fluid, the spiral plug is pushed into the piston closing the spiral path. By controlling the fluid flow by way of a tortuous path, the amount of fluid backflow through the piston is minimized if not eliminated, thus eliminating the need for an annular overflow chamber, thereby simplifying the design of the piston. In order to minimize problems related to the sealing of the piston within the dispensing cartridge, the piston may be provided with one or more radially extending sealing lips. These sealing lips are used in lieu of or in conjunction with an O-ring. The sealing lips further simplify the design by eliminating the O-ring as well as the need for an annular chamber adjacent thereto as well as problems relating to chemical attack of the O-ring by the fluid within the dispensing cylinder. In an alternative embodiment for use that is particularly adapted with non-aggressive fluids, the piston is provided with a single sealing lip and an O-ring.

After removal of the needle from a body tissue, rotating the inner tube in the opposite direction causes the members to return substantially to their original positions and thereby return the inner tube substantially to its original diameter and allow the biopsy piece to be removed or ejected from the needle.

A compact sensor for detecting the presence of biological or chemical species includes a microdisk laser and a wavelength shift detector. The microdisk laser is coated with a biological or chemical recognition element, which binds preferentially with a target analyte.

The presence of a wavelength shift indicates the presence of the target analyte, and the magnitude of the wavelength shift corresponds to the mass load of the target analyte on the sidewall surface of the microdisk laser.

Particulate generation has been a problem in semiconductor device processing in highly corrosive plasma environments. The problem is exacerbated when the plasma is a reducing plasma. Empirically produced data has shown that the formation of a plasma spray coated yttrium-comprising ceramic such as yttrium oxide, Y2O3-ZrO2 solid solution, YAG, and YF3 provides a low porosity coating with smooth and compacted surfaces when such ceramics are spray coated from a powder feed having an average effective diameter ranging from about 22 [mu]m to about 0.1 [mu]m.
