Abstract: A method for generating patterned strained regions in a semiconductor device is provided. The method includes directing a light-emitting beam locally onto a surface portion of a semiconductor body; and manipulating a plurality of dislocations located proximate to the surface portion of the semiconductor body utilizing the light-emitting beam, the light-emitting beam being characterized as having a scan speed, so as to produce the patterned strained regions.

Abstract: In the present invention, it is disclosed that Artemis forms a complex with the 469 kDa DNA-dependent protein kinase (DNA-PKcs) in vitro and in vivo in the absence of DNA. The purified Artemis protein alone possesses single-strand specific 5? to 3? exonuclease activity. Upon complex formation, DNA-PKcs phosphorylates Artemis, and Artemis acquires endonucleolytic activity with respect to single-stranded nucleotides, including 5? and 3? overhangs, as well as hairpins. Further, the Artemis:DNA-PKcs complex can open hairpins generated by the RAG complex from a 12/23-substrate pair. Thus, DNA-PKcs regulates Artemis by both phosphorylation and complex formation to permit enzymatic activities that are critical for the hairpin opening step of V(D)J recombination and for all of the 5? and 3? overhang processing in nonhomologous DNA end joining.

Abstract: A structure and method for controlling the behavior of dislocations in strained semiconductor layers is described incorporating a graded alloy region to provide a strain gradient to change the slope or curvature of a dislocation propagating upwards or gliding in the semiconductor layer in the proximity of the source and drain of a MOSFET. The upper surface of the strained semiconductor layer may be roughened and/or contain a dielectric layer or silicide which may be patterned to trap the upper end of dislocations in selected surface areas. The invention solves the problem of dislocation segments passing through both the source and drain of a MOSFET creating leakage currents or shorts therebetween.

Abstract: A pushbutton switch having a housing (10), a push button (12) mounted in said housing for axial movement between a normal position and a depressed position, the push button being spring-loaded into the normal position and carrying an elastically mounted cam element (24), at least one micro-switch (14) arranged in the housing, and a switch actuating rocker mounted within the housing for pivotal movement, the switch actuating rocker having an actuating arm (20) for actuating the micro-switch and a transmission arm (18) engaged by the cam element to hold the actuating rocker in the normal position when the push button is in the normal position, move the actuating arm away from the micro-switch when the push button is initially depressed, move the actuating arm to a position actuating the micro-switch on movement of the push button to its depressed position, and force the actuating rocker to its normal position on return of the push button from the depressed position to the normal position.

Abstract: In the present invention, it is disclosed that Artemis forms a complex with the 469 kDa DNA-dependent protein kinase (DNA-PKcs) in vitro and in vivo in the absence of DNA. The purified Artemis protein alone possesses single-strand specific 5′ to 3′ exonuclease activity. Upon complex formation, DNA-PKcs phosphorylates Artemis, and Artemis acquires endonucleolytic activity with respect to single-stranded nucleotides, including 5′ and 3′ overhangs, as well as hairpins. Further, the Artemis:DNA-PKcs complex can open hairpins generated by the RAG complex from a 12/23-substrate pair. Thus, DNA-PKcs regulates Artemis by both phosphorylation and complex formation to permit enzymatic activities that are critical for the hairpin opening step of V(D)J recombination and for all of the 5′ and 3′ overhang processing in nonhomologous DNA end joining.

Abstract: A hydraulic damper is designed, for example, as a piston/cylinder unit. The arrangement has a part (for example, a piston) forming a vibrational system by means of a spring. Vibrations acting on the damper arrangement are greatly attenuated virtually only in the resonant range of this vibrational system, because only in this case can vibrations of high amplitude be excited and a high dissipation of energy by way of hydraulic flows in channels and between cylinder chambers take place.

Abstract: Apparatus for controlling the oscillations of a mold for continuous casting of metal, the mold being mounted on a table which is connected, in turn, to three spaced apart drives and three load relief springs; three displacement path transducers track each of the drives; a source of reference signals provides reference signals representing the desired oscillation, as to contour, amplitude and rate; actual and reference signals are compared by and in stages which provide correction signals for the drives.

Abstract: An ozone pipe is provided for use in a large production plant employing a large number of such pipes in parallel. The pipe of the invention avoids the usual drawbacks for such pipes in large plants in having the metal electrodes melt without discharge of the fuse, or having the fuses discharge in a large number of pipes simultaneously without any indication in the glass pipes of the cause. The above is achieved by the use of a fuse with a capacity within the range of between about 0.63 and 0.15 amperes, and by providing a resistance in each tube mounted in series with the fuse in the power supply.
