Title: Tdma mobile unit frequency synthesizer having power saving mode during transmit and receive slots
Inventor: JOKURA JUN
IPC: H04B7/26
Filed: 1993-04-13
Granted: 1998-08-18
Abstract: During transmit and receive slots of a TDMA frame, a reference pulse source is made inactive for power savings purposes, and during an idle slot of the frame it is rendered active to supply pulses to a phase alignment circuit where initial phase alignment is established between an output of a frequency divider and the reference pulse. Phase-aligned signals are supplied to a phase comparator, the output of which is coupled to a switched filter bank during the idle slot to cause a selected loop filter to develop a voltage according to the output of the phase comparator to drive a voltage controlled oscillator to generate a local carrier for allowing a channel switching to be effected for a possible hand-off. The connection between the phase comparator and the filter bank is cut off during the transmit and receive slots to maintain that voltage for a closed-loop operation during the next idle slot.

Abstract: The phase transformation temperature of a metal silicide layer formed overlying a silicon layer on a semiconductor wafer is lowered.      First, a refractory metal is disposed proximate to the surface of the silicon layer, a precursory metal is deposited in a layer overlying the refractory metal, and the wafer is heated to a temperature sufficient to form the metal silicide from the precursory metal. The precursory metal may be a refractory metal, and is preferably titanium, tungsten, or cobalt. The concentration of the refractory metal at the surface of the silicon layer is preferably less than about 101 atoms/cm3. The refractory metal may be Mo, Co, W, Ta, Nb, Ru, or Cr, and more preferably is Mo or Co. The heating step used to form the silicide is performed at a temperature less than about 700°C, and more preferably between about 600-700°C. Optionally, the wafer is annealed following the step of disposing the refractory metal and prior to the step of depositing the precursory metal layer. Preferably, this annealing step is performed at a wafer temperature of at least about 900°C.

Abstract: L'invention concerne un procédé et un dispositif (14) servant à appliquer une chaleur régulée, de façon à effectuer une ablation, afin de traiter l'hypertrophie ou l'hyperplasie prostatique bénigne (BPH). D'après le procédé et le dispositif (14), l'énergie est transférée directement dans la masse du tissu sans endommager les tissus environnants. Le dispositif s'arrête automatiquement quand une parmi plusieurs zones environnantes, y compris l'urètre (2), ou la masse environnante, ou les organes contigus (6), dépasse les limites de température de sécurité prédéterminées. L'application constante de l'énergie de radio-fréquence pendant une durée constante déterminée permet de mettre le procédé en application en toute sécurité, ce qui évite des interventions électrochirurgicales ou d'autres opérations invasives, tout en soulageant rapidement le patient en lui imposant un temps limité de convalescence. L'intervention peut s'effectuer dans le cabinet du médecin, sans qu'il soit nécessaire d'hospitaliser le malade.
