Title: Magneto-optical recording disk
IPC: G11B11/10
Filed: 1988-05-30
Abstract: A magneto-optical recording disc 10 has an erasable magneto-optical recording structure 14 for recording the intensity modulation of the incident radiation 12 in the presence of a magnetic field. The radiation impinges on an incidence side 13 of the recording disc. The magneto-optical recording structure 14 is applied on a side of a substrate 16 facing away from the incidence side. The material of the substrate has excellent load-bearing characteristics, chosen without regard to the optical transmission characteristics of the material. A supporting structure 18 of coaxial sealing rings 19-19 keeps the window at a distance from the side of the magneto-optical recording structure which is facing the incidence side 13 of the recording disc. Between the window and the recording structure there is an air gap 22. The window is optically transparent and has a minimal birefringence, so that the radiation incident on the incidence side 13 of the recording disc 10 is passed on through the window with minimal optical delay. As a result, the difference of the effective Kerr angle of the polarisation rotation, corresponding to the different directions, namely upwards or downwards, of the magnetisation on the magnetooptical recording layer 15 of the recording structure 14, is primarily in relation to the recorded data and not dependent on the optical delay through the window. In the case of further exemplary embodiments of recording discs, the air gap is filled with a transparent adhesive and, instead of the magnetic recording structure, an appropriately adapted interference multi-layer structure is used, in order to intensify and optimise the difference of the effective Kerr angle of the polarisation rotation according to the different directions of magnetisation on the magneto-optical recording layer of the multi-layer structure. In the case of one of these embodiments, two such recording discs are arranged with their substrates back to back or share a common substrate, in order to form a double-sided magnetooptical recording disc.

IPC: G02B6/44
Filed: 1988-08-20
Abstract: An ultraviolet-curable coating composition 
adapted for the buffer coating of optical glass fiber 
consists essentially of an acrylate-capped 
polyurethane in admixture with at least about 25% of 
its weight of liquid monoethylenically unsaturated 
monomer having a low glass transition temperature 
below about 0°C. The acrylate-capped polyurethane is 
based on a generally linear polyurethane which is the 
reaction product of organic diisocyanate with a 
stoichiometric deficiency of a modified diol, this 
modified diol being the diester reaction product of 
polyoxytetramethylene glycol having a molecular 
weight of from about 200 to about 2000 with a 
stoichiometric deficiency of a long chain 
ester-forming hydrocarbon-substituted dicarboxylic 
acid or ester-forming substitution product thereof. 
This provides a higher molecular weight 
polyoxytetramethylene glycol which includes ester 
groups and a long chain hydrocarbon substituent to 
improve microbending resistance while taking 
advantage of the better water resistance provided by 
the polyoxytetramethylene glycol component.

Title: Method and apparatus for recognising a signal contained in a video signal
IPC: H04N7/167
Filed: 1988-09-22
Abstract: Private providers of television programmes often have their transmissions radiated encrypted so that the interested party must use a pay decoder. The decoder then evaluates an unencrypted signature which must be correctly identified with respect to any noise on the transmission path. 
<??>To detect the signature, the invention uses a correlation circuit which is supplied with the signal components existing in the video signal and with a reference signal. The correlation circuit is followed by a threshold circuit in which the error rate is determined. When the rate drops below a predetermined error rate, the signature is detected as correct and the decoder is enabled. 
<??>The invention can be used in so-called pay TV systems.

Title: Inter and intra priority resolution network for an asynchronous bus system
IPC: G06F13/37
Filed: 1988-10-10
Abstract: A data processing system includes a plurality of 
units including a bus interface unit (BIU), each of 
which couple in common to different positions along an 
asynchronous common bus. The BIU couples to a 
plurality of local units which connect to a high speed 
local bus. The asynchronous common system bus includes 
a distributed tie-breadking priority which consists of 
a plurality of like priority network sections. The BIU 
includes a priority resolver which incorporates the 
priority network section having the highest priority 
access to the asynchronous bus. The priority resolver 
includes a local priority resolver circuit for 
resolving priorities between local requestors within a 
minimum amount of time. The priority network section 
and local priority resolver circuit are interconnected 
so that the signal generated by the network section 
request circuits to request use of the asynchronous bus 
is applied to the local priority resolver circuit and 
to the common bus at the same time. This permits both 
bus resolution cycles for resolving external and 
internal requests to proceed in parallel. Thus, access 
to the system bus will always be resolved within a 
single bus resolution cycle of operation.
