Abstract: Disclosed is an aromatic copolymer comprising a
plurality of aromatic copolymer chains, each comprising
(A) recurring 2,6-diphenylphenol units and (B) phenolic
comonomer units, each comonomer unit being independently
selected from the group consisting of (i) an oxyphenylene
monomer unit which is monosubstituted with a
monovalent aromatic group or a halogen atom, (ii) an α-oxynaphthylene
monomer unit, (iii) a β- oxynaphthylene
monomer unit, and (iv) an oxyphenylene monomer unit
which is substituted with at least one aliphatic group,
wherein the amounts of (A) and (B) are from 50 to 98 %
by weight and from 2 to 50 % by weight, based on the
weight of the aromatic copolymer, provided that, when
(iv) is present as the comonomer unit, the amount of
(iv) is 20 % by weight or less, based on the weight of
(B), and wherein the aromatic copolymer has a weight
average molecular weight of from 1,000 to 3,000,000. A
method for producing the aromatic copolymer is also
disclosed. The aromatic copolymer of the present
invention has excellent electrical characteristics
(such as a low dielectric constant), an excellent heat
resistance, excellent film-forming properties, low
water absorption properties and an excellent adhesion
to other materials, and can be advantageously used as a
material for various electronic parts.

Abstract: A method for automatic format detection in video pictures is
proposed. In this method a black bars analysation step is
performed wherein for each possible aspect format (14:9, 16:9,
2:1) a top and/or bottom area (B1 i , B2 i ) is defined in which it
is analysed whether a black bar (13, 14) is present or not.
Second, a centre analysation step is performed wherein for each
possible aspect format a centre area (L i )is defined in which it
is analysed whether an active picture area is present or not.
Third, a horizontal transition analysation step is performed
wherein it is analysed whether a horizontal border (10, 12)
between a dark area and the active part of the picture is
present or not. Forth, a format choice step is performed,
wherein a picture aspect format is selected on accord of the
results of the previous analysation steps. The method can be
used for controlling the zoom operation in a TV receiver with
16:9 picture tube. It also can be used for controlling the
recording function of a video recording device. Furthermore, an

Abstract: The system has a female section (6) with at least two facing and symmetrical hooks (11,12) to define two longitudinal spaces (13, 14) for the assembly male section (7). One space is in a bell mouth shape, with the larger diameter at the free end. The second space (14), of the longitudinal and rectangular section, forms at least two female shoulders (15, 16) for the hooks. The male section unit (17) has a smaller diameter than the bell mouth shape larger diameter, to give a common male shoulder (18) to be locked in place. The female shoulders (15,16) are at a slight angle to give a harpoon locking action on the inserted male section (7) when locked into the female section (6). The female shoulders (15,16) have a nipper action, to spread apart when the mushroom head (17) of the male section (7) is passed between them, and then spring back to retain it by the rear shoulder face (18). The female section can be a cylindrical socket, with at least three hooks separated by longitudinal openings. It gives a truncated cone space and a cylindrical space to take the conical head of the inserted male section through the opening into the space. The male section is metallic.

Abstract: An improved geometry for scroll wrap inner portion includes a groove which facilitates
opening of the compression chambers to the discharge ports early in the cycle of the
orbiting scroll. Stated one way, a forward end of the scroll wrap tip is thinner than a
portion spaced from the forward end. A first curve defines the forwardmost end of said
tip and extends to a forward ledge. A second circular curve is spaced from the forward
ledge and extends to a rear ledge. An intermediate curve connects the forward and rear
ledges. The rear curve is centered on a second radius, and if the second radius were
extended beyond the rear ledge, the extension would move to a position spaced from the
forward ledge and towards the opposed wrap. The swing radius for the scroll
compressor wrap measured begins at the position wherein the forward ledge of one wrap
faces the rear ledge of an opposed wrap begins on one side of zero, then crosses zero
with an increasing scroll wrap, and then moves to an opposed side of zero. The
inventive scroll compressor wrap achieves more rapid and smooth opening of the
compression chambers to the discharge ports.

Abstract: Field or frame memories are often used in television receivers for video signal processing functions, such as noise reduction and/or flicker reduction. Television receivers also have graphic features such as teletext, menu-driven control systems, multilingual subtitling, an electronic TV-Guide, etc. A method of processing television picture signals including both video (VID) and graphic (GFX) information is disclosed. In accordance with the invention, the video and graphic signals are individually compressed in accordance with different (lossy and lossless, respectively) compression algorithms (22; 24), stored in the same field or frame memory (21), and decompressed (23; 25) after processing (20). Herewith a significant reduction of memory capacity is achieved without adversely affecting the graphics quality. The invention is not only applicable to locally generated graphic signals (TXT, OSD) but also to graphic information which is detected (26) as being embedded in a received television signal.
