IPC: B29C47/06
Filed: 1990-02-09
Abstract: A self-adhering laminate of a polyamide multi-­
polymer on thermoplastic polyurethane is prepared by 
disrupting the crystalline structure of the polyamide 
sufficiently through polymerization of at least 3 
polyamide precursors such that a melting point in 
range of 140°C to 190°C is obtained. The laminate 
provides better resistance to solvents on the poly­

Patent EP-0404173-A3 (EP)
Title: Multiple access satellite communication system for mini-earth station networks
IPC: H04L1/16
Filed: 1990-06-22
Abstract: A multiple access satellite communication system in 
which a plurality of mini-earth stations each transmits 
data packets to a hub earth station via a satellite over 
an inbound channel, while the hub station transmits to 
the mini-earth stations in a broadcast mode over outbound 
channels. Each mini-earth station selectively uses a 
fixed assignement access method, random access method, 
and demand assignment access method, depending on the 
frequency of the transmission from a terminal connected 
thereto, the amount of transmitted data, and whether or 
not the transmission from the terminal is periodic. The 
hub station outputs a reception response signal to the 
outbound channels by determining whether or not a conflict 
of data packets or a transmission error has occurred on 
the inbound channels. Packets for re-transmission are 
sent out to the inbound channels by the demand assignment 
access method at all times, with no regard to the access 
method used at the time of transmission.

Patent EP-0558004-A3 (EP)
IPC: H01L23/522
Filed: 1993-02-25
Abstract: Electrically conducting vias and lines are created by a three step process. First, a controlled amount of a soft, low resistivity metal (12) is deposited in a trench or hole to a point below the top surface of the dielectric (10) in which the trench or hole is formed. Subsequently, the low resistivity metal (12) is overcoated with a hard metal (16) such as CVD tungsten. Finally, chemical-mechanical polishing is used to planarize the structure. The hard metal (16) serves the function of protecting the low resistivity metal (12) from scratches and corrosion which would ordinarily be encountered if the low resistivity metal were subjected to the harsh chemical-mechanical polishing slurries. An ideal method for partially filling trenches or holes in a substrate is by sputtering at elevated temperatures such that metallization at the bottom of a trench or hole separates from metallization on a top surface adjacent the trench or hole. An etchback procedure may also be used to separate metallization in a trench or hole from metallization adjacent a trench or hole. Trenchs and holes may also be filled by selective deposition. In addition, trenches and holes may also be lined by a metal liner (18) prior to metallization (12) deposition which can serve as a diffusion barrier.

Abstract: A fire retardant (flame retardant, flame resistant) plastic moulding composition of improved stability comprises   from 50 to 85% by weight, based on the total amount of the moulding composition, of an olefin polymer and from 15 to 50% by weight, based on the total amount of the moulding composition, of a flameproofing system comprising   from 80 to 50% by weight of an ammonium polyphosphate of the formula (NH4PO3)n, in which n is a number from 200 to 1000 (= component A) and from 50 to 20% by weight of a product of the reaction of tris(2-hydroxyethyl) isocyanurate (THEIC) of the formula <IMAGE>  with an aromatic polycarboxylic acid of the formula  Ar(COOH)m  (= component B).   The flameproofing system to be employed according to the invention increases both the processing temperature of the plastic moulding composition and significantly reduces the water solubility of parts of the moulding composition after processing. In addition, the flameproofed plastic parts have a reduced tendency to exude constituents of the flameproofing system.

Title: Method of improving the adhesion to a polyimide surface by formation of covalent bands
Inventor: MUKERJI PROSANTO K
IPC: C08J7/12
Filed: 1995-04-03
Abstract: A polyimide surface (18) of a semiconductor device (12) is
pretreated with a hydroxyl amine solution at an
elevated temperature to form functional groups that react with an
underfill encapsulant (16) to form covalent bonds during a cure
cycle between the polyimide layer and the encapsulant material
between the semiconductor device and a substrate (10). The
hydroxyl amine solution include a reagent such as 2,(2-aminoethoxy)
ethanol dissolved in a solvent like N-methyl
pyrolidione at 65°C for sixty seconds. The hydroxyl amine
solution may be sprayed onto the polyimide layer, or deposited by
vapor deposition. The semiconductor die with the treated
polyimide layer is attached to the substrate by DCA methods
leaving a gap between the assemblies. The encapsulant is
introduced between the semiconductor die and the substrate and
cured to form a covalent bond with the polyimide layer and an
environmental seal between the assemblies resulting in enhanced
adhesion.

Patent EP-0766430-A3 (EP)
Inventor: BUSCHE MATTHEW T
IPC: H04L12/56
Filed: 1996-09-19
Abstract: A setup procedure employing distributed hop-by-hop routing reduces the number
of signaling messages needed to establish a service (i.e., connection), thus enhancing
network performance. A service is setup between an origination node and a destination
node which are a part of a network of communication nodes interconnected by links.
Each node maintains a topological database representing the network topology. Initially,
a setup message for initiating the service is transmitted from the origination node to a
neighboring node that serves as a local node. The topological database is then updated
after the local node receives the setup message by eliminating links connected to a
particular set of nodes. This set of nodes includes those nodes other than the local node
that have previously transmitted a setup or failure message for the service. A shortest
path is next determined from the local node to the destination node over the updated
topology and another setup message is transmitted from the local node to a first
neighboring node in the shortest path. The previously-mentioned steps are repeated,
beginning with the step of updating the topological database, where the neighboring node
now serves as a subsequent local node. The steps are repeated until either a setup message
reaches the destination node so that the service enters a connected state or no shortest
path is found at the origination node, which indicates that the service has failed to enter a
connected state.
