Patent EP-0177194-A3 (EP)
IPC: C30B15/10
Filed: 1985-09-05
Abstract: An apparatus for the production of a compound semi­
conductor single crystal comprises a high-pressure container 
(1), a crucible (2) and a crucible stand (3) disposed inside the 
high-pressure container (1), a heat generator (4) encircling 
the crucible and the crucible stand, a heat-insulating member 
(5) disposed outside the heat generator, and a crystal pulling 
device (6) disposed above the crucible (2) in such a manner 
as to be freely moved in a vertical direction. The crucible 
stand (3) and/or heat-insulating member (5) is formed of 
sintered pieces of poly-type aluminium nitride containing as 
a sintering aid at least one member selected from the oxides 
of the Group IIIa and IIa elements or sintered pieces of a 
aluminum nitride coated with said poly-type aluminium 
nitride.  
     This apparatus permits production of a single crystal of 
larger size and higher quality than the conventional counter­
type, because the crucible stand (3) and the heat-insulating 
member (5) yield to much less deterioration due to oxidation 
and exhibit higher heat-insulating ability and the melt of raw 
material for crystal is minimally contaminated by the product 
of oxidation.

Title: Die bonding process
IPC: H01L23/488
Filed: 1985-12-18
Abstract: A process for bonding a silicon die to a package. This process comprises the following steps: (a) providing to the back surface of the die a barrier layer which is impervious to silicon; (b) providing to the barrier layer a layer of gold; and (c) bonding the die to the package by activating a binder composition disposed at the interface of the package and the layer of gold. The barrier layer prevents the migration of silicon to the gold layer, both at the time of application of the gold layer to the die and at the time of bonding the die to the package. Titanium and tungsten are preferred barrier layer materials, while the preferred binder composition is a gold-/<.>tin alloy solder. The prevention of silicon migration into the gold produces highly reliable bonds.

Abstract: A method of consolidating a tubular composite 
article of polymeric matrix material and fibrous rein­
forcing material, comprising enclosing a length of the 
tubular composite article in a tubular protective 
member and advancing the protective member to carry 
the length of the article thus enclosed through a con­

Filed: 1988-07-15
Abstract: A pattern recognition system comprises at least one pair 
of basic associative units each having at least first and second 
unit ports for receiving pattern signal groups, respectively 
and a third unit port for outputting a pattern signal group. 
Each of the basic units operates to derive weighting values for 
respective signals of the pattern signal groups inputted to the 
first and second unit ports of the basic unit itself in accordance 
with the degree of consistency between a previously given 
weighting pattern and respective patterns specified by the 
pattern signal groups inputted to the first and second unit 
ports of the basic unit itself. Each of the basic units also 
operates to modulate the respective signals of the pattern 
signal groups inputted to the first and second unit ports of the 
basic unit in accordance with the derived weighting values and 
to totalize the modulated signals so as to form an output signal 
outputted form the third unit port of the basic unit itself. The 
third unit port of one of the basic unit pair is coupled to the 
first unit port of the other basic unit, and the third unit port of 
the other basic unit is coupled to the second unit port of the 
one basic unit. Thus, the third unit port of one of the basic unit 
pair gives an recognition output.

Filed: 1988-11-29
Abstract: The regulator has at least one inlet connector (10) for receiving a brake-operating pressure, and at least one output connector (13) for supplying braking pressure to the brake members of the vehicle. It includes valve means for controlling the braking pressure, situated in the body and including a rocker arm (20) with a variable fulcrum (33) which is arranged to determine the ratio between the brake-operating pressure and the braking pressure in dependence on the position of the fulcrum (33). The movement of the rocker-arm fulcrum (33) on variation of the load is controlled by a control device (60; 21-42) comprising a body (60) in which at least one piston (24) is sealingly slidable, the piston being movable, against the action of first and second reaction springs (29, 30), by an operating pressure which depends on the load bearing on the vehicle. The first spring (29) is inside the second (30) which is locked against rotation but translatable in the body (60). The piston (24) carries a member (33) which can cooperate with the rocker arm (20) to act as its fulcrum (33). A manually-operable adjustment device (35-42) is associated with the body (60) of the device for moving the fulcrum (33) and is adapted to enable the loading of the first spring (29), its position relative to the body (60) and also the elastic constant of the second spring (30) to be adjusted independently.

Title: Echo canceller
IPC: H04B3/23
Filed: 1989-03-17
Abstract: An echo canceller provided with an expected echo generating unit (101), which generates an expected echo of a transmission signal, and a frequency offset correction unit (75) which detects a phase error between an echo in a received signal and an expected echo from the expected echo generating unit (101) and corrects the frequency offset for the expected echo by an offset frequency estimate based on the phase error, wherein use is made of the expected echo after offset correction by the frequency offset correction unit (75) so as to suppress the echo in the received signal, the frequency offset correction unit (75) using the phase error obtained after normalizing the phase error by the magnitude of the echo in the received signal. By this, it is possible to perform frequency offset correction adaptive to the far-end echo characteristics. Further, it is desirable to perform the frequency offset correction after it is confirmed that the rate of change of the output from a subtractor for cancellation of the near-end echo has become almost zero.
