Abstract: Germanium needles are used as emitter electrodes (12)
for use in low particle generating gas ionizers in general
and static eliminators in particular. They oxidize with
minimal incorporation of nitrogen, and the negative
polarity emitters oxidize at a greater rate than the
positive polarity emitters. Negative polarity silicon
emitters generate several orders of magnitude greater
particle emissions than either positive or negative
germanium electrodes. The mean particle size is about 0.015
µm. No particles were shed from these needles. Lowest
particle generation is achieved when germanium electrodes
are purged with dry air.

Abstract: A semiconductor device, for instance a fast switching rectifier,
which includes an epitaxially
grown region on a substrate. At least one PN junction in
the epitaxial region has an improved ability to withstand
transient signals such as electrostatic discharges of
significant magnitude by having a portion of
the epitaxially grown layer between the substrate and the PN
junction having
a graded resistivity, the resistivity increasing towards the PN
junction, preferably varying exponentially with thickness. In one
embodiment for N type substrate the gradation is from about
0.005 ohm-centimetres to about 7-12 ohm-centimetres over a
thickness of about 15 micrometres, this being accomplished by
varying the amount of impurity during epitaxial growth.

Abstract: A call handling mechanism provides a resource manager for controlling the
allocation of functional modules to process a received call. Each of the functional
modules can be implemented as a software application, preferably implemented in the
form of a bean, such as a Java bean. The resource manager allocates the functional
modules in accordance with the priority order. Different types of applications are given
priority numbers within different ranges so that, for example, a voice application such as
a voicemail application will always precede a facsimile application, which in turn will
precede a data application. In this manner, reliable call answering can be provided using
third party supplied call handling applications which are pre-allocated priority numbers
in an appropriate range for the type of application.

Abstract: A cross-head (3), sliding vertically within a portal frame (1), carries a line of tool-rods (10), each ending in an olive-shaped expansion part. Finned tubes arrayed (15) on a rack (11), hinged at the frame foot, are each aligned with a tool-rod when an actuator (13) raises the track to the vertical. The expansion parts are then simultaneously forced, hydraulically, through the tubes, producing the desired diameter. On changing the array, some tools have to be added or removed. With the cross-head raised and the rack lowered, a magazine (19), holding tools in vertical tubes, is pushed (21, 22) under the cross-head, which lowers the old and picks up the new set while locking plates are released and reapplied. The head is newly displaced to disengage the selected rods while the magazine that the motor mechanism returns finally to the skipped position to permit the widening operation. Selectors (12) on the rack determine the new configuration.

Title: Usinage de metaux et alliages au laser a impulsions ultracourtes
Inventor: PERRY MICHAEL D
IPC: B23K26/06
Filed: 1998-05-19
Abstract: L'invention a pour objet un procédé d'usinage à haute précision (découpe, perçage, sculpture) de métaux et alliages. En utilisant des impulsions d'une durée de l'ordre de 10 femtosecondes à 100 picosecondes, un usinage d'une extrême précision peut être effectué essentiellement sans zone affectée thermiquement ou par des chocs. Du fait que les impulsions sont ultracourtes, il n'y a qu'une conduction thermique négligeable au-delà de la zone éliminée, ce qui se traduit par des contraintes thermiques ou des chocs négligeables pour le matériau, au-delà d'environ 0,1-1 micron (suivant le matériau concerné) à partir de la surface usinée au laser. En raison de cette durée ultracourte, l'intensité élevée ( > 1012W/cm2) associée à l'interaction fait passer le matériau directement de l'état solide en un plasma ionisé. Une expansion hydrodynamique du plasma, permet de ne plus avoir à recourir à des techniques auxiliaires d'élimination du matériau, et d'obtenir des surfaces usinées de qualité extrêmement élevée, avec une re-déposition négligeable dans l'entaille ou sur la surface. En raison d'un chauffage négligeable au-delà de l'épaisseur de matière enlevée, la composition du matériau restant n'est pas affectée par le procédé d'usinage au laser. Ce procédé permet un usinage d'une haute précision des alliages et même des métaux purs, sans aucun changement de la structure du grain.

IPC: H03L7/089
Filed: 1998-10-08
Abstract: A lock detector for a phase locked loop circuit generates a lock detection signal indicative of whether the output signal is within a prescribed lock condition of the reference signal. The lock detector samples the control signal, examines a plurality of samples according to criteria associated with the prescribed lock condition between the reference signal and the oscillator output signal, and generates a lock signal indicative of the lock condition being met if the samples satisfy the criteria. In a favorable embodiment, the lock detector forms a first group of samples sampled at a rate controlled by the reference signal and a second group of samples at a rate controlled by the oscillator output signal of the phase locked loop. The samples are stored and shifted at the respective clock rates in respective shift registers. The contents of each stage of the shift registers are then examined according to a logic function. In an embodiment, the control signal includes first and second commands and is subjected to an initial logic function whose output is sampled by the shift registers.
