Title: Multiple-voltage supply power amplifier with dynamic headroom control
Inventor: LEWYN LANNY
IPC: H04L27/26
Filed: 2001-11-01
Abstract: A monolithic integrated circuit amplifier has a gain stage (202) and a buffe r stage (210). The buffer stage includes an output stage and two separate voltage supplies (+Vlo, +Vhi), the second of which has a greater magnitude than the first. Switching circuitry is included that is connected to the output stage via a regulator bus. When an output demand voltage is less than  a switch-over threshold, current to the output stage is provided substantially  from the first voltage supply (+Vlo); when the output demand voltage is greater than the awitch-over threshold, current to the output stage is provided substantially from the second voltage supply (+Vhi). Collector voltage at the output stage is dynamically controlled to be greater than the  emitter voltage by a difference voltage that increases proportionally as output voltage increases above the switch-over threshold. This difference voltage is commonly reffered to as "headroom". The dynamic headroom control circuitry preferably includes circuitry for predicably setting and controlli ng the headroom voltage at switch-over and smoothly increasing the headroom voltage up to maximum output voltage.

Title: Tantalum and tantalum nitride powder mixtures for electrolytic capacitors substrates
Inventor: TRIPP TERRANCE B
IPC: B22F3/00
Filed: 2001-10-23
Abstract: A process for producing sintered pellets made from blends of refractory meta l and refractory metal nitride powders were found to have a higher fraction of  intra-agglomerate pores than those made from the refractory metal or refractory metal nitride alone resulting in improved capacitor grade powders , anodes and finished capacitors therefrom. The pellet porosity and total intrusion volume maximizes when the mixture is in the 50-75 W/W% refractory metal nitride range. The total pellet pore surface area was found to be relatively independent of refractory metal nitride concentration above 50%. A substrate consisting of a 50/50 or 25/75 W/W% refractory metal/refractory metal nitride powder mixture should produce solid capacitors with higher capacitance recovery and lower ESR.

Abstract: A method for loading an aircraft comprises receiving a load onto a first loading platform and lifting the load by raising this loading platform, subsequently transferring the load from this loading platform onto a second lowered loading platform, and finally lifting the load by raising this platform so that the load may finally be transferred from the second loading platform into the aircraft hold. The unloading procedure is the reverse of this procedure. An associated mobile aircraft loading device is provided with a vertically displaceable platform to receive the load, as well as hoisting mechanisms for the platform. The upper surface of the loading platform, in its uppermost position, is coplanar with the load level of an aircraft, and in its lowermost position, is coplanar with the load level of a raised platform of another loading device. Aircrafts with a very high load level may he simply loaded and unloaded using such a procedure.
