Title: Programmable sub-surface aggregating metallization structure and method of making same
Inventor: KOZICKI MICHAEL N
IPC: H01L27/04
Filed: 1998-12-04
Granted: 2003-08-21
Abstract: A programmable sub-surface aggregating metallization structure (100) includes an ion conductor (110) such as a chalcogenide glass which includes metal ions and at least two electrodes (120, 130) disposed at opposing surfaces of the ion conductor (110). Preferably, the ion conductor (110) includes a chalcogenide material with Group IB or Group IIB metals. One of the two electrodes (120,130) is preferably configured as a cathode and the other as an anode. When a voltage is applied between the anode and cathode, a metal dendrite (140) grows from the cathode through the ion conductor (110) toward the anode. The growth rate of the dendrite (140) may be stopped by removing the voltage or the dendrite (140) may be retracted back toward the cathode by reversing the voltage polarity at the anode and cathode. When a voltage is applied for a sufficient length of time, a continuous metal dendrite (140) grows through the ion conductor (110) and connects the electrodes (120,130), thereby shorting the device. The continuous metal dendrite (140) then can be broken by applying another voltage. The break in the metal dendrite (140) can be reclosed by applying yet another voltage. Changes in the length of the dendrite (140) or the presence of a break in the dendrite (140) affects the resistance, capacitance, and impedance of the programmable sub-surface aggregating metallization structure. <IMAGE>   <IMAGE>

Title: Tufting apparatus
Inventor: INGRAM GARY L
IPC: D05C15/24
Filed: 1990-10-26
Granted: 1995-09-26
Abstract: Apparatus for producing tufted textile goods employs a plurality of hollow needles which serve as backing openers, the backing openers being carried on a widthwise extending member which is reciprocated in a vertical direction to cause the backing openers to penetrate a backing.  Yarn is transported pneumatically through the backing openers and implanted into the backing as yarn tufts, the backing being shifted in the transverse direction by an amount corresponding to the spacing between adjacent backing openers in order to implant a transverse row of tufts.  A knife blade is associated with each backing opener and positioned on the opposite side of the backing so as to engage the flat angled surface of the backing opener which forms its pointed tip.  The angled surface is formed with an upwardly and inwardly extending slot which serves to capture and center yarn exiting the opening in the angle surface, and which provides a sharp edge which cooperates with the blade for cutting the yarn.

Title: Mass spectrometer having a multichannel detector
Inventor: BATEMAN ROBERT HAROLD
IPC: H01J49/48
Filed: 1990-06-01
Granted: 1999-08-17
Abstract: The invention typically provides a double focusing mass spectrometer comprising an ion source (55), an ion momentum analyzer (56), a multichannel detector (58) and a multielectrode electrostatic ion-energy analyzer (57), wherein the energy dispersing field is generated by arrays of electrodes disposed in groups above and below the ion beam. By appropriate selection of the potentials applied to the electrodes, the focusing properties of the analyzer can be changed, allowing different extents of the mass spectrum to be accurately focused on the face of the detector (58) as it is tilted by the actuator (61) at different angles to the ion beam (64) emerging from the analyzer (57). This enables the spectrometer to simultaneously record either a small part of a mass spectrum at high resolution or a larger part at a lower resolution. Alternative arrangements of the detector which allow a similar result to be obtained arc also disclosed.

Granted: 2001-04-17
Abstract: Thermodynamically stable ceramic composites are provided for use in high temperature oxidizing environments. The composites comprise high strength alumina fibers (Al2O3) in a ceramic matrix. The ceramic matrix comprises material similar to the fibers to improve compatibility of the composite materials. A material selected from the .beta.-alumina and magnetoplumbite family of materials is used to provide a weakly bonded interface between the fibers and the ceramic matrix. .beta.-aluminas and magnetoplumbites have weak layers as an intrinsic characteristic of their crystal structure, which comprises spinet layers (basically Al2O3) separated by very weakly bonded planes containing the .beta.-forming ions. The weak planes of these materials allow preferential debonding and sliding, and thus inhibit crack growth across the interface between the fibers and the ceramic matrix. The alumina fibers can be coated with .beta.-alumina by any of several methods such as heat treating the fibers in an atmosphere containing the desired .beta.-forming ions. Composite structures can be fabricated by placing the coated fibers in powdered matrix material and hot pressing. .beta.-alumina can also be formed in situ within a preformed composite by providing the .beta.-forming ions in a compound that is phase compatible with the ceramic matrix material and then heat treating the composite to form .beta.-alumina at the fiber-matrix interface.

Title: Discharge excitation gas laser device
Inventor: KOSUGI NAOKI
IPC: H01S3/0971
Filed: 1991-12-23
Granted: 1995-07-25
Abstract: In a discharge excitation gas laser device such as an excimer laser device provided with laser medium gas and a pair of electrodes opposite to each other in a gas-tight vessel, the laser medium gas is discharge-excited while inverting the polarity of a DC pulse voltage applied to the pair of electrodes opposite to each other for every pulse.  In this way distribution of atoms and ions constituting the laser medium gas in the discharge region including the neighborhood of the main electrodes is made uniform even at a high repetition rate oscilla-tion.  Thus it is possible to realize a discharge excitation gas laser device having a good stability of DC pulse discharge without increasing unnecessarily the flow speed of the laser medium gas and no lowering in the pulse energy owing to a high efficiency operation.
