Patent EP-0263373-A2 (EP)
Inventor: LEITHNER KARL
IPC: C22C33/02
Filed: 1987-09-25
Abstract: The process is intended for producing mass components by conventional sintering technology and without additional hardening treatment, which are equivalent to hard castings with respect to their wear properties. They should have a surface hardness of about 50 Rockwell and only slight shrinkage. This is achieved by means of a sintered iron-nickel-copper-molybdenum alloy with added phosphorus, which has a carbon content of at least twice the added phosphorus. Essentially, its composition is as follows:
 1.0-5.0% by weight of nickel (Ni)
 1.0-3.0% by weight of copper (Cu)
 0.3-1.0% by weight of molybdenum (Mo)
 0.3-0.6% by weight of phosphorus (P)
 1.0-2,5% by weight of carbon (C),
 remainder: iron (Fe).

Abstract: A method forming high density multilayered glass-ceramic circuits with copper conductors is disclosed herein. In the process a preburnoff process is performed in an atmosphere including nitrogen gas with a very low partial pressure of oxygen, with the glass-ceramic temperature being raised gradually from 25°C to the binder burnout temperature. Burnout of the residual carbon in the binder material is then performed by maintaining that temperature for several hours in the presence of wet nitrogen gas and hydrogen, with a ratio of water vapor to hydrogen gas of 10⁴. The temperature is, then, lowered to at or slightly below said binder burn off temperature for approximately one hour. Subsequently, the temperature is raised to the coalescence and/or crystallization temperature of said ceramic material and held for two hours while remaining in the dry forming gas environment.

Abstract: The present invention is directed to a low-dielectric constant press board for oil impregnation insulation which comprises a poly(4-methylpentene-1) fiber and/or a poly(3-methylbutene-1) fiber and a kraft pulp. This press board may be formed by first laminating the mixed wet sheets of the poly(4-methylpentene-1) fiber and/or the poly(3-methylbutene-1) fiber and the kraft pulp, and then heating/pressing the laminate integrally. In this case, the wet sheets of the kraft pulp (2) alone may be disposed over and under the mixed wet sheets (1), or over, under and between the mixed wet sheets. Further, the press board may additionally contain at least one selected from polyethylene terephthalate fibers and polyphenylene sulfide fibers in an amount of less than 28 wt%.

Abstract: A passive sonar system which forms multiple receiver beams for detection of possible targets. The transducer array for the system includes a plurality of pairs of transducers (T,T' 1 -T 20 T' 20 ), the transducers of each pair lying along a generally radial line emanating from a central point. The output signal from the outer transducer of each pair is delayed by 90° or λ/4C relative to the inner transducer (D 1 -D 20 ), and the delayed signal is combined with the output signal from the other transducer of the pair in a summing amplifier (Σ 1 -Σ 20 ) so that only one signal per transducer pair need be sampled by a multiplexer (28) for transmission via a coaxial cable (32) to beamformer apparatus (30). The concept is applicable to groups of transducers with more than just a pair, i.e., with three or more transducers. Appropriate additional delays are provided with all of the output signals and delayed output signals of a group being received by a single summing amplifier.

Abstract: A digital processor is provided for performing an N-point convolution or correlation of q-bit coefficients with data words guard band extended to p-bits. The processor includes an array 10 of one-bit clock-activated gated full adder cells 12 arranged in N rows and q columns. Each cell 12 is arranged to input data, carry and cumulative sum bits and to output the data bit and new carry and cumulative sum bits corresponding to the product of the input data bit with a respective stationary coefficient bit. The output carry bit is recirculated on the respective cell 12. Cumulative sum generation is cascaded down array columns. Data moves along each row and thence to the next lower row via delaying means 22 providing a delay appropriate for correct partial product formation. Data is input bit and word serially to a first row cell 12 02  and thereafter moves along successive rows progressively further down the array 10. Sums of partial products output by the array 10 are accumulated according to bit significance by an accumulator device 60 arranged to accumulate successive convolution or correlation results in different adding means 80a and 80b. This avoids erroneous addition of contributions to different results. The array 10 is cascadable to provide larger processors. Cascaded arrays may be arranged to be fault tolerant, and a faulty array may be bypassed without operating speed penalties arising from bypass lines.

Abstract: An integrated circuit includes a patterned aluminum based interconnect clad on the top (15) and side portions (18,20) with a layer of transition metal (16,22). The cladding of transition metal prevents the formation of both vertical hillocks and lateral protrusions. Preventing these formations increases the reliability of an interconnect by significantly reducing passivation cracking and electrical shorting between interconnects which result from vertical hillock and lateral protrusion formations.

Abstract: Die Ionen-Cyclotron-Resonanz stellt eine bedeutende Methode der Massenspektroskopie dar. Sogenannte MS/MS-Experimente erlauben auch die Beobachtung von Reaktionen der untersuchten Substanzen. Diese Experimente sind jedoch sehr aufwendig, weil sie selektiv für jeden der eingesetzten Stoffe und jedes einzelne der Reaktionsprodukte besonders durchgeführt werden müssen. Die Beobachtung komplexer Vorgänge ist daher in der Praxis schwierig. Mit Hilfe einer zweidimensionalen ICR-Methode lassen sich Reaktionen der untersuchen Substanzen feststellen, wobei die folgende Meßsequenz Anwendung findet: P1 - t1 - P2 - τm - P3 - t2. Darin bedeuten P1, P2 und P3 HF-Impulse, von denen die HF-Impulse P1 und P2 die gleiche Frequenz haben. Diese Meßsequenz wird unter Veränderung von t1 mehrfach wiederholt. Auf diese Weise wird eine Vielzahl von in der Zeit t2 aufgenommenen Induktionssignalen erhalten, die dann durch Umsetzen vom Zeitbereich in den Frequenzbereich zu einem zweidimensionalen Spektrum führen. Das Umsetzen vom Zeitbereich in den Frequenzbereich kann durch eine zweidimensionale Fourier-Transformation oder nach der Methode der maximalen Entropie erfolgen.

Abstract: An optical resonator, preferably of a solid state laser (11) is tuned by one or more sheets (41, 52) of piezo-electric material bonded to one or more tuning facets of an optically transparent solid state member portion (12) of the resonator. A tuning voltage applied across the piezo-electric sheet (41, 52) tends to change the area of the bonded interface of the sheet (41, 52) to generate a set of tuning forces predominantly in the plane of the surface of the tuning facet. These tuning forces are transmitted through the tuning facet into the solid state portion of the optical resonator to produce a change in its refractive index and dimensional change which tunes the frequency of the optical resonator and the laser using same, if any. In a preferred embodiment, the piezo-electrically tuned optical resonator is an optically pumped ring resonator made of a lasant material such as Nd:YAG for tuning the output frequency of the ring laser (11).
