Abstract: A medical-surgical tube having a major lumen defined by an inner periphery of a wall of the tube, an injection lumen within the wall of the tube, and at least one one-way valve in the wall. The valve allows fluid to flow from the injection lumen through an outer or inner periphery of the wall of the tube and prevents return of the fluid back into the injection lumen. The tube can include a plurality of spaced-apart valves. The valve can be a piercing in the wall of the tube which is defined by opposed surfaces resiliently biased against each other and extending from the injection lumen to the outer or inner periphery of the wall of the tube.      Methods of manufacturing a medical-surgical tube having a major lumen defined by an inner periphery of a wall of the tube, an injection lumen within the wall of the tube, and at least one one-way valve in the wall. One method includes projecting a piercer such as a needle into the injection lumen, bending the tube in a slightly bent configuration and pushing a point of the needle through a portion of the tube wall located between the injection lumen and the outer or inner periphery of the tube. When a plurality of piercings are made, the needle can be backed up in the injection lumen, the tube can be advanced and the needle can again be pushed forward to form another piercing in the bent tube. Alternatively, the piercer can be pushed into the inner or outer periphery of the tube, through the wall and into the injection lumen. The needle can have a thin diameter and the method can be performed such that a tapered point of the needle passes part way or entirely through the wall of the tube when the valve is formed.

Abstract: The present invention discloses an ion beam gun wherein the ions are produced by radio-frequency excitation. A plasma is created in a vessel (100), or chamber, by ionizing gas molecules by means of a coil (230) about the outside of the vessel. The coil (230) receives radio-frequency energy which ionizes the gas molecules. The inside of the vessel contains an anode (242, 244) and resonator (250) to assist in shaping and containing the plasma. The resonator (250) acts as an internal electrode to produce eddy currents generated by the radio-frequency energy to enhance the plasma. A  multi-apertured screen grid (260) also helps contain and shape the plasma within the chamber while a multi-apertured accelerator grid (262) is used to extract the ions from the ion beam gun.

Abstract: An  upper  end portion  of  an  excavation  ripper  shank  is captively and removably retained in a ripper box using a specially designed flex pin connector longitudinally driven into generally aligned openings in the ripper box and shank.   The flex pin connector includes first and second rigid pin members held in a spaced  apart,  parallel,  laterally  facing  relationship  by  a plurality of elastomeric members bonded to facing side surfaces of the pin members.  When the flex pin connector is driven into the aligned  box  and  shank  openings  the  elastomeric  members  are compressed, causing the first and second pin members to drive the shank  and  box  into  forcible  abutment  with  one  another  to substantially eliminate relative side-to-side play therebetween.    Additionally, as the flex pin connector passes through the first and second openings its first and second pin members are caused to pivot relative to one another about an axis parallel to the compression direction of the elastomeric members.  When the flex pin connector reaches its installed position the first and second pin members return to their original pivotal orientation,  and locking  projections  on  their  end  portions  releasably  block longitudinal removal of the flex pin connector.  A second flex pin connector, substantially identical to the first flex pin connector, is removably received in a third opening formed in the ripper box and has outer side portions that resiliently bear against the received ripper shank portion and an interior side surface portion of the third opening that faces such ripper shank portion.

Abstract: A method of an apparatus for extracting dielectric constants from ellipsometric data taken during the growth of a semiconductor thin film (10) and using the extracted dielectric constants to control the composition of the growing film by adjusting the growth conditions. An expression is used for the derivative of the pseudo-dielectric function with respect to the thickness of the thin film within a three-phase model, and the expression is exact to first order in thickness of the film. The expression is quadratic with respect to the dielectric function for a homogeneous thin film and additionally depends on the dielectric function of homogeneous substrate (12) underlying the thin film. Values of the measured pseudo-dielectric function are substituted for the dielectric function of the substrate, and the expression is then solved for the dielectric function of the thin film.
