Title: Process for polishing dissimilar conductive layers in a semiconductor device
Inventor: BAJAJ RAJEEV
IPC: H01L21/321
Filed: 1998-03-18
Abstract: A process of polishing two dissimilar conductive materials
deposited on semiconductor device substrate optimizes the
polishing of each of the conductive material independently, while
utilizing the same polishing equipment for manufacturing
efficiency. A tungsten layer (258) and a titanium layer (256) of a
semiconductor device substrate (250) are polished using one
polisher (10) but two different slurry formulations. The two
slurries can be dispensed sequentially onto the same polishing
platen (132) from two different source containers (111 and 112),
wherein the first slurry is dispensed until the tungsten is removed
and then the slurry dispense is switched to the second slurry for
removal of the titanium. In a preferred embodiment, the first
slurry composition is a ferric nitrate slurry while the second
slurry composition is an oxalic acid slurry.

Abstract: Memory is divided into a plurality of banks to store software
which is upgraded one bank at a time. By doing so, a memory with
the same size as one bank is only needed as the temporary storage
used when performing an upgrade. The terminal device only needs
a memory that is "1+1/n" times as large as a total software when
there are n banks, while a conventional terminal device needs a
memory that is twice as large as the total software. Two loader
programs are stored in different banks as a master loader program
used for download processing and a backup loader program. On
receiving a new loader program, one loader program is used to
write the new loader program over the other loader program so as
to upgrade the loader program. The backup loader program is
activated when the new loader program is to be written over the
master loader program.

Abstract: A receiving apparatus is used in a mobile
communication system which transmits and receives spread
spectrum signals between a base station and a mobile
station. In the receiving apparatus, the timing
detection region of a spread spectrum signal is set in
accordance with the intermittent receiving period. If it
is difficult for the mobile station to establish
synchronization with the base station over a long
intermittent receiving period due to errors accumulated
in the oscillator of the mobile station, the window
serving as the search area is expanded. Accordingly, the
capability of detecting the timing is increased, and
errors of the oscillator are compensated. Thus,
re-synchronizing operation and intermittent receiving
operation are reliably performed. As a consequence, even
by the use of a low-precision and simple-structured
oscillator in the mobile station, a low-powered receiving
apparatus in which an intermittent receiving operation
having a longer period is performed is provided.

Title: A method and apparatus for audio representation of speech that has been encoded according to the lpc principle, through adding noise to constituent signals therein
Inventor: GIGI ERCAN FERIT
IPC: G10L21/02
Filed: 1998-10-12
Abstract: Speech is received as a sequence of segments that are coded according to an LPC principle. The segments are reproduced for concatenated read-out in audio reproduction, by exciting an all-pole filter with recurrent signals in case of voiced speech and by white noise in case of unvoiced speech. In particular, the recurrent signals are globally represented as an accumulated series of periodic signals on the basis of mutually overlapping time windows. The reccurent signals are supplemented by noise for filtering through an amended LPC filter derived from the original LPC-filter by using information of pitch and formants, and of a voiced-unvoiced deichotomy. The filter is determined as depending on at least a subset of the four quantities Global Noise Scaling, Pitch Dependent Noise Scaling, Amplitude Dependent Noise Scaling, and Inter-Formant Noise Scaling.

Abstract: The continuous process for hyperactivation of fluids for sterilization uses a sterilizing fluid which is mixed with a gas that is inert with respect to the fluid. A sterilizing mixture is obtained which is subsequently evaporated by means of introduction into an evaporation tube in a condition of annular motion, where a liquid phase of the mixture flows against the heated walls of the evaporator at a slower speed than the gaseous phase thereof, which flows in the central zone of the evaporator, internally of the liquid phase. A gaseous vapour/inert gas mixture is thus obtained, which is subjected to a waiting period during which the mixture flows through a transit device which transfers it to a sterilization chamber, a temperature of which is lower than a dewpoint temperature of the gaseous mixture, where a product is sterilized.

Abstract: The present invention relates to a bi-directional configurable optical add/drop
circuit. A symmetrical arrangement of serially coupled wavelength specific filters which
include central add and drop ports isolated in both directions by filters provides a bi-directional
circuit. Add and drop ports are coupled by a reflecting means, such as
movable mirrors, or a movable double sided mirror. Alternatively, redirecting means
comprise an opto-electronic, or other means, for providing a selectively reflective or
transmissive interface. The reflecting means has a first position to direct a channel
passed through a first filter to the drop port. If a new channel is added, the reflecting
means couples the new channel through a second filter to the output port. In a second
position, the reflecting means is moved from the beam path, permitting the channel to
pass through the circuit without being dropped. In this way selected channels can be
dropped, while others are allowed to pass. The reflecting means may be rotated or a
second redirecting means substituted to reconfigure the circuit for signals propagating in
the reverse direction to provide bi-directional coupling to the drop receiver and add
transmitter. By applying absorption material to the surface of the reflecting means, an
attenuation function can be added to the add/drop circuit. The configuration can be
modified in operation. Numerous add/drop circuits can be arranged in parallel to address
a large number of channels. A number of broad band filters first separate and direct
selected channels to each add/drop circuit.
