Abstract: The arrangement includes a DC motor which is supplied by a rectifier (2) which is supplied for its part over a transformer (1) with AC voltage. A control arrangement (7) controls DC voltage supplied to the DC motor over the rectifier. A line synchronization signal is produced from the AC voltage of the transformer, and is supplied as a drive signal to the control arrangement. The control arrangement produces the synchronization signal itself during the running of the DC motor. The line synchronization signal is preferably produced at switched off DC motor from the secondary voltage of the transformer.

Abstract: A frame/field converter circuit(10) addition-processes
image data constituting respective fields in a
ratio corresponding to an image pickup mode or the like and
outputs the resulting image data. As a result of this, it
is possible to perform addition processing on image data
constituting respective fields in an optimum ratio
corresponding to an image pickup mode or the like and output
the resulting image data. This makes it possible to improve
the frequency characteristic and S/N ratio of the image and
thereby enhance the quality of the displayed image. A contour
compensation circuit(6) performs contour compensation
processing with respect to the frequency band of the image
data in correspondence with the zoom magnification. As a
result of this, it is possible to mitigate the level of the
return noises generated in correspondence with the zoom
magnification and thereby prevent the deterioration of the
frequency characteristic and S/N ratio of the image to thereby
enhance the quality of the image. An electronic zoom
circuit(9) performs zoom processing according to both of
even-line data and odd-line data output from an all-pixel
readout system solid image pickup element.

Abstract: A method for manufacturing a floor covering involves leading a glass fibre matt 1
from a supply reel 2 onto a conveyor belt 3. At a first scattering station 4, a
saturation material is scattered onto the matt 1 to form a scattered layer. The matt
1 is then led between upper and lower heated belts 10, 11 to gel the scattered
layer. The belts are then passed between a pair of smoothing/nipping rollers to
form a layer of uniform thickness. The belts are then cooled and the matt 1 with
saturation layer applied is wound for further processing. In an alternative
arrangement a saturation material is scattered directly onto a substrate belt at the
first scattering station 4, a glass fibre matt 26, is applied over the scattered material
and, at a second scattering station 28, an amount of the saturation material or a
different material is scattered onto the matt 26.

Abstract: La présente invention concerne un filtre d'accès factorisable utilisé conjointement avec d'autres filtres analogues dans un réseau privé virtuel de manière à contrôler l'accès des utilisateurs présents chez des clients du réseau à des ressources d'information fournies par des serveurs du réseau. Chaque filtre d'accès utilise une copie locale d'une base de données de contrôle d'accès destinée à déterminer si une demande d'accès à l'information est faite par un utilisateur. On répercute sur toutes les autres copies locales les modifications effectuées par des administrateurs dans les copies locales. Chaque utilisateur appartient à un ou plusieurs groupes d'utilisateurs et chaque ressource d'information appartient à un ou plusieurs ensembles d'informations. L'accès est autorisé ou refusé selon des politiques d'accès qui définissent l'accès en terme de groupes d'utilisateurs et d'ensembles d'informations. De même, les droits des administrateurs sont déterminés par des politiques d'administrations. L'accès est, en outre, autorisé uniquement si les niveaux de confiance d'un mode d'identification de l'utilisateur et si le chemin du réseau par lequel l'accès est effectué sont suffisants pour le niveau de sensibilité de la ressource information. Si nécessaire, le filtre d'accès chiffre automatiquement la requête par un procédé de chiffrement dont le niveau de confiance est suffisant. Le premier filtre d'accès au chemin exécute la vérification de l'accès, chiffre et authentifie la requête, les autres filtres d'accès au chemin ne répétant pas la vérification d'accès.

Abstract: Conductor track structures arranged on a nonconductive support material, especially fine conductor track structures, composed of a heavy-metal base and a metallization layer applied to the base, and a method for producing the conductor track structures. The heavy-metal base contains heavy metal nuclei which are formed by breaking down a nonconductive heavy metal complex by using UV radiation produced by an excimer laser. The heavy metal complex is applied to the entire microporous surface of the support material and covers the surface of the support material in the area of the conductor track structures. Conductor track structures produced according to the invention are comparatively easier to produce than previously known conductor track structures and exhibit very good adhesion.

Abstract: A control circuit (30) drives the coil (20) of a
contactor (10) in response to a control voltage being
applied. The control circui (30) t includes a power
supply (31) that produces a regulated output voltage from
the control voltage. The onset of the regulated output
voltage starts a timer (34) which controls the width of
pulses produced by a PWM controller (33). The pulses
control a transistor (Q2) that applies the control
voltage to the coil (20). Initially the pulses cause a
high current to flow through the coil (20) to close the
contactor (10) and after an interval of time the timer
(34) signals the PWM controller (33) to shorten the
pulses which applies lesser current to the coil to keep
the contactor closed. A flyback circuit (36) provides a
relatively low reverse voltage drop path in parallel with
the coil (20) to maintain the electromagnetic field
during the periods between the pulses. When the control
voltage is removed to open the contactor (10), the
flyback circuit (36) provides a high reverse voltage drop
path to promptly dampen the coil current.
