Abstract: Cette invention concerne un système et un procédé d'adaptation dynamique du débit binaire d'un utilisateur dans un système de télécommunication cellulaire à accès multiples par répartition dans le temps (TDMA), ceci afin d'obtenir une qualité vocale optimale sur une gamme étendue de conditions de canaux radio. Ce système contrôle de manière continue la qualité des canaux radio tant dans la liaison ascendante que descendante, et adapte dynamiquement la combinaison de codage de la parole (21), de codage de canaux (22), de modulation (23) et de plusieurs créneaux temporels (27) attribuables par appel du système, ceci afin d'optimiser la qualité vocale dans des conditions déterminées. Les diverses combinaisons de codage de la parole, de codage de canaux, de modulation et de créneaux temporels attribuables dans le système sont désignés comme des types de combinaisons (1-5), tandis que les fonctions de coût correspondantes sont définies. En désignant et en choisissant la fonction coût présentant le coût le plus bas pour des conditions de canal radio déterminées, ce système permet d'obtenir une qualité vocale maximale dans les limites imposées par la conception du système.

Abstract: La présente invention se rapporte à un filament de coupe conçu pour tailler et couper de la végétation, du type filament de coupe utilisé sur les cultivateurs motorisés à tête rotative tels que débroussailleuses et appareils de taille des bordures. En cours d'utilisation, ces filaments de coupe produisent un bruit aigu, déplaisant, qui s'ajoute au bruit du moteur d'entraînement de la tête rotative, ces bruits créant une pollution sonore extérieure. Des législations visant à limiter le bruit à un niveau estimé acceptable sont en cours d'élaboration et pourraient entrer prochainement en vigueur. Le fil de coupe (1; 10') selon l'invention se caractérise en ce qu'il comporte des ondulations (2; 6; 12') qui se répètent dans le sens longitudinal.

Abstract: Production of a hot gas corrosion resistant joint (20) between pipes (10), which have a corrosion protective thermally sprayed layer (12), involves weld depositing a corrosion resistant material onto one of the pipes in its butt end region (14) adjacent the other pipe prior to thermal spraying. Alternatively, a pipe piece, made of or coated with corrosion resistant material, is welded to the pipes (10) prior to thermal spraying. Preferably, the corrosion resistant layer (22) is applied to a width (b) of 0.5-150 (preferably 2-50, especially 5-30) mm on both sides of the pipe joint plane (E) and has a thickness (e) of 0.5-10 (preferably 1-5) mm. When a coated pipe piece insert is used, the corrosion resistant coating is preferably applied by thermal spraying or weld deposition. Preferably, the butt ends (14) of the pipes (10) are welded together by a root weld layer of boiler-plate steel and a top layer of corrosion resistant alloy, this top layer optionally being located in the weld deposited corrosion resistant layer (22). A Ni, Ni-Cr, Co, Fe or Fe-Cr alloy is preferably used as weld additive material for weld depositing the corrosion resistant layer (22) at the joint plane (E) or on the pipe piece, the layer (22) being produced by plasma powder weld deposition, autogenous welding or arc welding. The thermally sprayed layer (12) may be a sprayed and melted layer of a self-fluxing alloy, such as a self-fluxing Ni-Cr-B-Si, Ni-B-Si or Co alloy, or a sprayed layer of non-melted Ni, Ni-Cr, Fe or Co alloy and may be applied by autogenous flame spraying, high velocity flame spraying (HVOF) or plasma spraying.

an essentially predetermined take-off angle and at a take-off velocity which can be selected
with the aid of the angular velocity, with the instantaneous angle () between the radial line (48)
on which the delivery end is situated and the radial line (49) on which is situated the location
where the spiral stream (9) and the path of the rotating impact member (14) intersect one another

Abstract: An improved method of forming a contact hole 122 through
an insulating layer 112 is disclosed herein. In one
embodiment, a first mask layer 110 (e.g. polysilicon or
photoresist) is formed over the insulating layer 112. The
first mask layer 110 is patterned and etched to expose a
portion of the insulating layer 112. The exposed portion of
the insulating layer 112 is then etched to form a contact hole
having a bottom surface and an inner side surface. A sidewall
mask later 120 (or sidewall pipe 120) is formed along the inner
surface of the contact hole. The bottom surface of the contact
hole is then etched using the sidewall mask layer 120 as an
etch mask to form a contact hole 122. Finally, the contact
hole can be filled with a conductive material.

Abstract: A microprocessor preemptively write-backs dirty
entries of an internal cache. Each cache entry is checked
once each predetermined time period to determine if the
cache entry is dirty (705). If dirty, a write history is
checked to determine if the cache entry is stale (706). If
stale, the cache entry in preemptively written back to main
memory and then marked as clean (711). The write history
includes a count of the number of consecutive predetermined
time periods during which there is no write to the cache
entry. The cache entry is stale if the count exceeds a
predetermined number (710). For each check of the write
history the nonwrite count is incremented if the cache
entry has been written to during the prior cycle (709) and
decremented if not (707). Alternatively, the nonwrite
count is set to zero if the cache entry has been written
to. The dirty cache entry may be marked as clean upon
copying to the write-back buffer or, alternatively, when
the write-back buffer writes the dirty cache entry to the
main memory. If a write address matches the address of any
write-back buffer entry, the matching entry is flushed from
the write-back buffer.

Abstract: An Insulated Gate Bipolar Transistor has a gate in the form of a trench positioned in a p
region in a silicon body. The device operates in a thyristor mode having a virtual emitter
which is formed during operation by the generation of an inversion layer at the bottom
of the trench within the p region. The device is inherently safe and turns off rapidly as
removal of a gate signal collapses the emitter. As the trench gate is situated within the
p region, it can withstand high voltages when turned off as the reverse electric field is
prevented from reaching the trench gate

The system preferably also comprises regeneration circuitry in operative connection with the pump motor. The regeneration circuitry operates to redirect energy produced from momentum of the pump motor while the switch is in the second state back to the pump motor. Transmitting circuitry is preferably provided to transmit a motor signal proportional to the speed of the pump motor during the second state of the switch. Preferably, the switch is modulated between the first state and the second state using a processing or control unit such as a microprocessor. The processing unit preferably controls the modulation of switch in response to the motor signal received from the transmitting circuitry.
