Patent EP-0862209-A2 (EP)
Inventor: SCHULZ-HARDER JUERGEN DR-ING
IPC: H05K3/00
Filed: 1998-02-19
Abstract: Processes are claimed for producing an electrical circuit substrate by applying first and second metallisations (3, 4) onto both sides of a ceramic layer (2), the first metallisation (3) being a copper foil applied by a DCB (direct copper bond) technique. In one process, a substrate (1b) with a through-contact (10) is produced by providing an opening (11) in the ceramic layer and applying the second metallisation (4) as a metal-containing paste by a thick film or thin film technique such that the paste is also applied onto the opening (11) and a first metallisation area exposed in the opening. In another process, in which a metallic interlayer is to be formed for thermal and/or electrical connection of the substrate (1a) to another component (e.g. a metal base plate, 6), the second metallisation (4) is much thinner than the first metallisation (3) and is applied as a metal-containing paste by a thick film or thin film technique. Also claimed is a substrate produced by one of the above processes.

Abstract: A friction testing machine and method for measuring friction
characteristics between a test sample and a friction surface. The machine and
method are particularly suited for measuring the coefficient of friction between a
rubber specimen or a tread element and different friction surfaces at different
sliding velocities, contact pressures and orientations. A preferred embodiment
of machine is self-contained and portable, configured for easy and quick
changing of the friction surface, and provides for rotating the test sample about
an axis normal to the sliding surface and the direction of movement of the
sample relative to the friction surface. In general, a friction test machine

sample in frictional engagement with a friction surface, and a motion device for
effecting relative movement between the friction surface and sample holder in a
first direction. Also provided is a variable weight loading device on the sample
holder for loading the sample holder such that a selected load can be applied to
the sample normal to the friction surface, and a force measurement device for
obtaining a measurement indicative of the frictional force resisting such relative
movement between the sample holder and the friction surface effected by the
motion device.

IPC: G06K7/00

Abstract: At the beginning of a data transfer a pulse of known duration is transmitted from the read-write unit to the transponder. The transponder measures the pulse duration and calibrates the decoder with the measured value. All following pulse times are now evaluated w.r.t the correction value. During the data transfer the coupling between the read/write unit and the transponder can fluctuate and the received pulse time change. The calibration therefore must be reset. The difference between the pulse time of different logic conditions is constant so the distortions of the pulse time only effect the absolute times but not the differences. The signals (0,1) have a constant section and a section which serves as the difference characteristic between both signals. The constant section is effected by the possible distortion, so for correction and compensation only one time is determined, which is subtracted from all incoming pulse times or added to them to compensate for the distortion.

Abstract: To provide a cold-cathode tube lighting circuit which
quickly and smoothly carries out lighting of a cold-cathode
tube and prevents damage of a piezoelectric transformer as
an inverter transformer in the lighting circuit, the
lighting circuit is provided with a protection circuit for
detecting a primary current of the piezoelectric
transformer. The protection circuit stops operation of an
oscillator for driving the piezoelectric transformer when
the primary current is excessive. The protection circuit
may be provided to detect excess of a secondary voltage of
the piezoelectric transformer. When the cold-cathode tube
is used as a backlight for a liquid crystal display driven
by the use of a scanning frequency, a dimmer circuit is
used for producing a dimmer signal with a dimmer frequency
and a controlled duty ratio given by a manual selector for
controlling start and stop of the oscillator according to a
desired brightness of the backlight. The dimmer frequency
is obtained from frequency division of the scanning
frequency. The controlled duty ratio is also modified
corresponding to the divided frequency.

Abstract: Techniques for comparing blocks of pixels (103, 107) in digital image encoding. The techniques apply a pattern of elements containing contiguous pixels to the blocks being compared, and only the pixels (105) in the elements are compared. The pixels are contiguous in the horizontal dimension of the digital image, which ensures that the block matching process is sensitive to small-scale vertical features of the image. A version of the technique which is particularly advantageous for use with DSP's that can process the pixels in a word in parallel uses checkerboard patterns in which each element is a word. Variations on the patterns take into account the fact that the block of pixels being compared may be word-aligned, misaligned by one pixel, misaligned by two pixels, and misaligned by three pixels.

Abstract: The fabrication of superconducting wires and rods having desired and
consistent electrical and mechanical properties, in particular those based on
Yttrium Barium Copper Oxide (YBCO) and Bismuth Strontium Calcium Copper
Oxide (BSCCO), is disclosed. The first fabrication step is to form an extrudable
paste by mixing YBCO or BSCCO superconducting powder with a set of organic
additives, which include binder, plasticizer, lubricant, dispersant, and a solvent.
The following additional steps are performed on both YBCO and BSCCO based
wires or rods: (i) using a piston extruder to extrude the superconducting wire or
rod; (ii) drying the wire or rod to remove the solvent; and (iii) subjecting the wire
or rod to a binder burn-out treatment to remove the remaining organic additives.
In addition, YBCO wires and rods also require a sintering step, while BSCCO
wires and rods also require cold isostatic pressing and heat treatment steps. The
formation of cracks in thicker YBCO and BSCCO based rods during the drying
and heating process steps is avoided by extruding hollow rods. The additives,
processing parameters, and processing stages used to fabricate the
superconducting wires and rods help achieve desired and consistent electrical and
mechanical properties.

Abstract: A ball-covering needlefelt produced by needling a fibre
batt in a range of angles including a plurality of
angles which are non-perpendicular to the plane of the
batt. The range of angles is preferably achieved by
the batt being curved during needling, the batt
conveniently being curved in its direction of travel
through the needling machine. The needleboard of the
needling machine is preferably correspondingly curved. 
     The needling process produces a needlefelt having a
high degree of fibre entanglement (comparable to woven
ball-covering felts) and enables achievement of
characteristics necessary for good wear and abrasion
resistance without the excessive consolidation in
conventional ball-covering needlefelts that leads to
loss of flexibility (tending to faulty ball covering)
and poor dynamic characteristics (making such balls
unsuitable for professional use). 
     The invention is particularly applicable to the
manufacture of championship-quality tennis balls.
