Patent EP-0363578-A3 (EP)
IPC: C08L71/12
Filed: 1989-07-12
Abstract: The invention relates to polymer mixtures 
which comprise a polyphenylene ether and a polyoc­
tenylene. By using as a polyphenylene ether a mixture of 
at least two polyphenylene ethers, one having a com­
paratively low viscosity and one having a comparatively 
high viscosity, a polymer mixture is obtained having 
improved properties. The properties are improved in par­
ticular with repect to the flow properties, while no 
reduction of the heat distortion occurs.

a phenolic compound and an aromatic aldehyde having a 
phenolic hydroxyl group with (meth)acrylic acid, and 
further reacting the reaction product with polybasic 
carboxylic acid or an anhydride thereof; a composition 
comprising the resin and a cured product of the resin 
or the composition.

Title: Semiconductor having the coupled quantum box array structure
IPC: H01L29/15
Filed: 1989-11-17
Abstract: The present invention offers a semiconductor 
having the quantum box structure, where the quantum 
box structures consisting of quantum boxes (1) and 
(4) and the barriers (2) and (5) are arranged in 
adjacent positions. By combining the quantum boxes 
(1) and (4) with the barriers (2) and (5), electrons 
are confined in terms of quantum within the quantum 
box structure, and electron status having the mini­
band with finite width and the gap with finite width 
is generated so that the electrons can move between 
quantum box structures by tunnel effect. It is 
characterized in that the width of the miniband is 
smaller than the intrinsic energy of phonon, that the 
gap between the miniband generated from the lower 
energy level and the miniband generated from the 
next lowest energy level is bigger than said intrinsic 
energy, and that most of the electrons are in the 
miniband status generated from the lowest energy 
level. This makes it possible to suppress the 
lattice vibration by confining the electrons within 
the quantum boxes while enabling electric conduction 
and to improve the dependency of electron mobility 
on temperature in semiconductor.

Patent EP-0326436-A3 (EP)
IPC: G06V30/162
Filed: 1989-01-30
Abstract: An optimal image-quality selection apparatus includes a 
quantizer (2) to quantize the image from a scanner. The quantizer 
outputs video signals (b1, b2) representing the image at different 
depth levels. Graphic blocks are extracted by extractors (3, 4) 
and counters (5 - 8) count for each video signal the total number 
of graphic blocks (e1 and e2) and the number (f1 and f2) of 
graphics blocks having a predetermined size. Dividers (9, 10) 
calculate the ratio (f1/e1 and f2/e2 respectively) of the number 
of graphic blocks having a predetermined size to the number of 
all graphic blocks of the image for each of the depth levels of 
colour, and a comparator (11) selects the image having the largest 
of the ratios as an image of optimal quality.

Title: Knitting method
IPC: D04B1/22
Filed: 1989-09-26
Abstract: Knitted joins are made in double jersey knitted 
articles using a method which minimises the effect of hole 
formation at the join. Single jersey edges (14, 18) are 
knitted along the edges (8, 9) to be joined, being knitted 
on from one to six needles in each of the courses of 
knitting which form part of the edge of the join. The 
edgings (14, 18) need not extend along the whole length of 
the join. In a further embodiment superimposed strips 
(15) of single jersey knitting are knitted between the 
edgings (14, 18) so as to split hole formation into two 
smaller series which are less noticeable. With this 
embodiment, one or both edgings (14, 18) can be omitted. 
The method is useful for upholstery fabric joins, par­
ticularly for vehicle seat covers, where exposure of the 
padding is to be avoided.

overspray of the powder from contacting the substrate 
adjacent to the areas to be coated, a pair of air 
nozzles (66,68) are directed at the area of the pipe 
adjacent to the area to be coated.

Title: Method and apparatus for casting metal alloys with low melting temperatures
IPC: B22D17/04
Filed: 1989-11-03
Abstract: A metal casting process for producing melt-out 
metal cores and the like made of metal alloys with low 
melting temperatures achieves a casting with uniform 
density, high quality finish and a fine grain 
structure. The process and apparatus do not require 
the pre-pressurization of a charging cylinder and 
permit closed dies to be used. The apparatus comprises 
a molten metal alloy tank (10), a cylinder (14) in the 
tank (10) having at its base a connection to a 
passageway (22) leading through the tank (10) to a die 
(32) located outside the tank (10). A valve (18) is 
provided in the passageway (22), located in the tank 
(10) having a first position where the passageway (22) 
to the die (32) is open and a second position where the 
passageway (22) to the die (32) is closed. In the 
second position, a valve port (64) provides a 
connection from the cylinder (14) to the molten metal 
alloy (12) in the tank (10). A valve actuator (52) 
moves the valve (18) from the first to the second 
position, a piston (30) within the cylinder (14) and a 
power system raises the piston (30) in the cylinder 
(14) with the valve (18) in the second position to fill 
the cylinder (14) with molten metal alloy (12) and 
lower the piston (14) with the valve (18) in the first 
position to inject molten metal (12) into the die (32). 
In a preferred embodiment, a second valve (26) is 
located outside the tank (10) and in the passageway 
(22) to the die (32). The second valve (26) operates 
in conjuction with the first valve (18) in the first 
position to allow the injection of molten metal alloy 
(12) into the die (32).

Title: Method for notifying a terminal user of an asynchronous event occurrence
IPC: G06F9/46
Filed: 1989-02-28
Abstract: A method is disclosed for notifying the user of 
a terminal attached to a host processor of the occurrence 
of an asynchronous event affecting the user. The notifi­
cation method determines whether or not the user is in 
communication with the host processor and then generates 
and displays an icon, or other selectable graphic repre­
sentation of the asynchronous event at the user's termi­
nal. Selection of the graphic representation by the user 
will display additional details of the asynchronous event 
to the user at his or her terminal. In one embodiment of 
the present invention, an indication of the asynchronous 
event is stored at the host processor if the user is not 
in communication with the host processor and displayed to 
the user after communication is initiated.

invention is to provide transgenic plants constitutively transcribing sense or antisense 
mRNA strands of DNA sequences encoding plant PRPs or transcribing sense or antisense 
mRNA strands of DNA sequences substantially homologous to genomic or cDNA 
sequences encoding plant PRPs, such transgenic plants thus having an enhanced

Title: Belt tensioner.
Inventor: STEFFAN HERMANN DR
IPC: B60R22/46
Filed: 1995-04-04
Abstract: The seat belt reel has a tensioning spring (29) and a geared hub (21) which is located inside the servo drive. This has an inner geared chamber (19) and a floating planetary gear wheel (28) between the hub and the chamber. The hub also has a radial wall (20) which forms one side of the pressure chamber with the planetary wheel the other side of the pressure chamber. The safety release control (14) activates the pyrolytic charge (17) to feed gas between he radial wall and the planetary wheel and thereby drive the seat belt spindle to tension the belt. The gearing of the planetary wheel and the hub is selected so that the planetary wheel follows the radial wall at approx. half the radial speed of the wall. This allows the wall to describe nearly two revolutions before stopping behind the planetary wheel. This provides a controlled tension length for the seat belt. <IMAGE>

across a common bandwidth. The data signals are received (via 114) by a base
station (110) as a composite spread signal. The base station partially despreads (in

individual wireless devices. The data rate and quality of service requirements for
each wireless device are used to calculate (in 144) a power factor and a control signal
is sent (via 152) to control the power from a particular wireless device. In addition,
a probability of transmission value is calculated based on an equivalent current load
value and an equivalent population value. The probability of transmission value
determines whether a particular wireless device is allowed access to an uplink
