Abstract: Oxides are etched with a halide-containing species and a low molecular weight organic molecule having a high vapor pressure at standard conditions, where etching is performed at preset wafer temperature in an enclosed chamber at a pressure such that all species present in the chamber, including water, are in the gas phase and condensation of species present on the etched surface is controlled. Thus all species involved remain in the gas phase even if trace water vapor appears in the process chamber. Preferably, etching is performed in a cluster dry tool apparatus.

Abstract: A chemical processing system for generating ultra-pure chemicals near the site of use. The system includes in series a supply of chemical or the site of use which may be a tank or drum and may be a point of use for semiconductor manufacturing, a concentrate sensor, a pump, a filter, a reactor vessel, and an optional heat exchanger, all connected by Kel-F tubing. Sources of pure filtered gas connect to the reactor vessel. An ozone generator can likewise connect to the reactor vessel. An optional isolation coil can likewise connect between the gas source and the reactor vessel.

Abstract: A system for causing uniform ablation of irradiated material of living tissue while not causing damage below a predetermined depth where laser radiation is provided sequentially and continuously in a predetermined pattern is disclosed.

Abstract: A white blackout fiber comprising a unitary fiber having a light blocking substance that substantially prevents the transmission of light therethrough and a whitening agent, where the whitening agent is present in an amount which provides for good after processing while the light blocking substance is present in the maximum amount which is masked by the whitening agent. Generally, the whitening agent is present in an amount between about 2.5-4% by weight of the fiber, and the whitening agent and light blocking substance are present in a ratio of between about 1000:1 and 800:1. Preferably, the whitening agent is TiO.sub.2 and the light blocking substance is carbon black.

Abstract: A surgical instrument for removing a cataract from a patient's eye including a hollow vibrating needle surrounded by two hollow infusion sleeves. The outer sleeve conforms to the incision in the eye and the inner sleeve prevents the outer sleeve from collapsing onto the hollow, vibrating needle.

Abstract: A device for retaining an electrical plug and extension cord to another plug and extension cord employs fastener strip elements secured to the cord adjacent to the plug by a circumferential clamping element. When the electrical plug is engaged with a corresponding socket, the mechanical fastener elements secured to the plug engage cooperating fastening elements affixed to the corresponding socket to retain the assembly in its connected state. The fastener elements may be mushroom-type fastener elements such as those available under the name Dual Lock.

Abstract: A self-ejecting garbage receptacle includes a container body for holding a garbage bag containing refuse, the container body having a bottom and a side wall enclosure with an open upper end, the side wall enclosure being connected with the bottom; a belt draped in the container body for normally supporting the bag in a lowered position in the container body, the belt having first and second opposite ends, with the first end being fixed to the side wall enclosure adjacent the open upper end; and a jug handle-shaped ejector handle for raising the belt, the ejector handle being connected with the second opposite end of the belt and being pivotally connected at one end thereof to an external surface of the container body; a hinge for pivotally connecting the ejector handle to the container body; a hook on an external surface of the container body; and a latch on the ejector handle for engaging with the hook to hold the belt in a raised position.

Abstract: An electronic cursor (12) is movable over a digitising table (10) on which a chart (16) has been spread. The cursor can give an indication of which way it should be moved to reach a defined position on the chart. The cursor can also convert positions in terms of x, y coordinates of the table into positions in terms of latitude and longitude co-ordinates of the chart, and can display the chart positions. The cursor can also determine bearings and distances between its own position and a defined position. Several other facilities are also available. Thus, the cursor can be used to facilitate the plotting of positions and courses on the chart and in reading off positions and bearings from the chart.

Abstract: Low frequency underwater acoustic radiator apparatus includes an air-trapping chamber with a lower portion open to the water, characterized by a mean density higher than that of water. A closed, rigid float element having a mean density equal to or lower than that of water is disposed with a selected loose fit within the chamber. When the chamber and float combination are submerged in water with a substantially vertical orientation of the chamber, the float element floats within the chamber, with the trapped air functioning as a spring coupling. A vibromotive element is coupled to the float element or the chamber element to induce oscillation of the coupled element. The coupling of the chamber and the float by the air spring converts the dipole oscillation of the oscillating element into a monopole pulsation suitable for a low frequency underwater sound radiator.

Abstract: In construction of a hi-hat cymbal holder for upper and lower cymbal plates, an extension rod holding the upper cymbal plate is supported at its lower end by a bush in a holder unit, the lower cymbal plate is supported stationarily by the holder unit and a rotary ring of a gap adjuster nut is mounted to the holder unit so that its rotation causes up and down movement of the extension rod via the bush. For cymbal gap adjustment, the rotary ring is manually rotated in the opening or closing direction so as to move, via the bush and the extension rod, the upper cymbal plate with respect to the lower cymbal plate. The adjuster nut is located close to the position of a player during performance and its rotary ring can be easily operated by one hand of the player only without disturbing stick operation by the other hand.

Abstract: A pair of non-prescription eyeglasses is mounted on a cantilevered support by a hanger that includes an element constructed of relatively stiff resilient plastic material. Such element includes a relatively wide main section having an aperture which receives the support arm, and a relatively narrow extension. The latter passes through the nose gap of the eyeglasses and is reversely bent to form a loop that surrounds the eyeglass frame bridge. In a first embodiment of this invention a rivet maintains the loop closed and prevents casual removal of the hanger from the eyeglasses. In a second embodiment a snap-type device holds the loop closed. This snap-type closure cannot be opened casually, at least for the first opening thereof.
