Title: Planar waveguides
Inventor: MAXWELL GRAEME DOUGLAS
IPC: G02B6/132
Filed: 1995-09-22
Abstract: The invention relates to the production of planar optical waveguides which
comprise composite path regions, e.g. for lasers. A layer (12) of a first glass
composition is deposited, and selectively etched to remove unwanted material so
as to leave behind path regions. A second glass composition (13) is deposited in
the form of a soot. The amount of the second glass composition (13) is calculated
to replace the amount of removed material whereby sintering melts the second
glass composition (13) to fill the space created by said selective etching. This
produces a composite layer which comprises said second glass composition (13)
optically connected to the previously deposited path regions. The composite layer
is selectively etched to produce interconnected path regions of two different glass
compositions. Preferably the first glass composition contains a lasing dopant, e.g.
erbium, and the second glass composition contains no lasing dopant.

Abstract: In a telecommunications network having a bandwidth manager and a plurality of switching nodes and links there-between, each link having defined bandwidth, where the telecommunications network is arranged to transmit one or more different traffic types between a pair of switching nodes and each link has a link manager and each traffic type has a traffic type manager there is a method of allocating bandwidth to different traffic wherein:
     each traffic type manager produces bids for bandwidth for its traffic type according to a common algorithm for the network;   each link manager reconciles the bids for its link and informs the traffic type managers of the allocated bandwidths;   each traffic type manager can change its bids if the allocated bandwidth does not fit with the requirements of its calls;   whereupon the bids are resubmitted and the link managers again reconcile the bids;   this process continues until no further changes are made by the traffic manager;   the link managers inform the switching nodes of the new bandwidth allocated to each traffic type on each link;   the traffic type managers allocate their bandwidth to their individual calls (if required) and inform the calling terminals of their new bandwidth.

Abstract: In a communication system, a number of different
transmissions are made through a common resource.
Data relating to the transmissions is available at
each of a number of different processors, each of
which determine how the transmissions are to share the
common resource. For example, in mobile satellite
communications system, a number of stations 12
transmit messages through the same satellite
transponder. Each earth station 12 receives
information about messages waiting for transmission at
the other earth stations 12, and determines the
transmission timing of the messages so that they do
not overlap at the satellite 14. 
     Where acknowledgement of the messages by mobile
terminals 16 is required, the timing of the
acknowledgements is controlled so that peaks in
acknowledgement traffic are spread in time relative to
peaks in message traffic.

Abstract: The present invention relates to analysis of analytes,
such as metals, refractories, and slag, for the content of
oxygen or oxides. 
     The present invention aims (1) to accurately separate
and analytically determine, without pretreatment of an iron
and steel to remove an oxide film as a contaminant formed
on the surface of the iron and steel, oxygen derived from
the oxide film as the contaminant and oxygen contained in
the iron and steel in the form of oxide inclusions, and (2)
to accurately and rapidly analyze an analyte for the oxygen
content or oxide content for each oxide contained in a very
small amount in the analyte. 
     The method for analyzing a metal for oxygen, using
inert gas carrying fusion/infrared absorption analysis,
comprises the steps of: placing a metal analyte in a
graphite crucible; heat-melting the metal analyte;
extracting a gas from the melt bath; and analyzing the gas
to determine the total oxygen content of the metal in the
form of a plurality of separated waves, wherein the metal
analyte is heated at a temperature rise rate of not more
than 20°C/sec in a period from a starting point A of a
first wave to a peak point B of the first wave, held at a
constant temperature in a period from the peak point B of
the first wave to an end point C of the first wave, and,
after the completion of the appearance of the first wave,
is heated to melt the metal analyte for further analysis. 
     The method for analyzing an analyte for oxygen or
oxide for each oxide, comprising the steps of: heating an
analyte in an inert atmosphere; reacting the analyte with
a carbon source while regulating the temperature rise rate;
extracting a CO gas successively generated as a result of
a reaction of oxygen in the analyte with the carbon source
into an inert gas stream; successively analyzing the
extracted CO gas by infrared absorption to determine the
amount of reacted oxygen or evolved CO; detecting a peak 
corresponding to the amount of reacted oxygen or evolved
CO from successively obtained data on the amount of reacted
oxygen or evolved CO; carrying out the analysis while
reducing the flow rate of the inert gas for each appearance
of the detected peak corresponding to the amount of reacted
oxygen or evolved CO to accumulate the data on the amount
of reacted oxygen or evolved CO in time sequence; and
determining the content of oxygen or oxide for each oxide
in the analyte from the accumulated data on the amount of
reacted oxygen or evolved oxide.

Abstract: The ink-jet print head 23 is provided with a sloped
surface 18 on the inner side surface between the inflow
channel 16 and the ink supply channel 14. The sloped
surface 18 gradually increases the cross-sectional area of
the ink flow path 45 from the inflow channel 16 toward the
ink supply channel 14. Accordingly, as the ink flows along
the sloped surface 18 into the ink supply channel 14, the
rate of flow of the ink gradually decreases due to the
increased cross-sectional area provided by the sloped
surface 18. As a result, the liquid ink flows more gently
into the ink supply channel 14.

Abstract: Prior to communication over the Internet and using a
different line, a first terminal (1) transmits to a second terminal (2)
a set of information including at least an IP address of the
first terminal on the Internet (4). Based on the IP address thus
transmitted separately, the party at the second terminal (2)
initiates communication over the Internet. This establishes
direct end-to-end communication (5) between the two terminals (1,2) over
the Internet (4). In a communication setup such as an
Internet-based telephone call wherein address information about
a desired party on the network is not previously known to a

communicate directly with each other over the network on an
