Abstract: An image composing apparatus adapted to produce a com­
posite image in which a value of each of picture elements is 
represented by a maximum value or minimum value of the bright­
ness of a video signal as well as a corresponding other signal

Title: Process and device for balancing rotating parts
IPC: G01M1/22
Filed: 1989-06-21
Abstract: The invention relates to a process for balancing rotating parts, in which compensation masses are arranged on the part to be balanced and in which the vibration acceleration of the rotating system formed by the rotating part and the compensation masses is measured and then integrated in order to obtain the vibration speed of the rotating system. A measure of the unbalance is obtained from the vibration speed in order to be able to monitor the unbalance during individual minimisation procedures in balancing. During a minimisation procedure, the size and/or the position in the rotating system of the individual compensation masses is altered, a further minimisation procedure being initiated as soon as the unbalance increases again during the current minimisation procedure. During a minimisation procedure, the maximum peak value of the vibration speed during a measuring time (Ti) is detected and stored. The peak value of the vibration speed during the current measuring time (Tn) is compared to the maximum peak value of the vibration speed of the immediately preceding measuring time (Tn-1). As soon as the instantaneous peak value of the vibration speed is greater than the stored maximum peak value of the vibration speed of the preceding measuring time (Tn-1), the next minimisation procedure is initiated.

Title: Method and device for controlling the strip width during the hot-rolling of strip
IPC: B21B37/00
Filed: 1989-12-22
Abstract: The invention relates to a method and a device for controlling the strip width during the hot-rolling of strip on a multiple-stand finishing line of a rolling mill train in which the speeds of the working rolls of each stand are controlled as a function of the instantaneous operating state. Here, the strip widths are sensed directly after the last reduction per pass and/or before the penultimate reduction per pass and are compared with the desired width in a width controller. In the event of deviations, a strip-supply controller for the strip supply between the last stands is acted upon, which strip-supply controller, by adjusting the roll nips, corrects the strip supply and the tensile stress of the strip in such a way that the strip width changes. The method is optimized by additional control of the strip thickness according to the novel strip-supply principle as well as by dispensing with some loop lifters. <IMAGE>

RAM is operating at a lower voltage, a data hold voltage may be 
supplied by a power pull-down device (M41-Figure 5) having a lower 
power consumption than the internal low voltage transformation circuit 
to achieve a saving in power consumption.

Title: Optical head
IPC: G11B7/1378
Filed: 1990-03-02
Abstract: An optical head in which reflected laser light is split 
into two optical paths by a polarized light beam splitter 
(23) while astigmatisms are produced in the laser light by 
at least one astigmatism generating element (22), and the 
two split beams are led so as to be incident upon two 
quadrant photodetectors, respectively. A focus error signal 
is obtained as an electrical signal by subtracting the sum 
of the quantities of light received by one of the diagonal 
pairs of regions among the quadrant regions of the two 
photodetectors (24, 25) from the sum of the quantities of 
light received by the other diagonal pair. This arrangement 
enables cancelling of influence of double refraction in a 
magneto-optic disk or the like, thereby making the optical 
head free of the problem of such influence.

Title: Electro-optical ifs finder
IPC: G06E3/00
Filed: 1990-04-20
Abstract: An electro-optical system that implements the 
self-tiling process of finding proper Iterated Function 
Systems for modeling natural objects. The system can 
operate in two different modes, a real-time interactive 
mode and an automated mode. The purpose of the system is 
to speed up the process of finding a proper IFS for a 
given object to be modeled. The system makes use of 
optical processing, including optical means for rotating, 
magnifying/demagnifying and translating an input image. 
Optical beamsplitters are used to combine transformed 
images to produce a tiled output image. In one embodi­
ment, an automated controller evaluates the goodness of 
the match between the tiled image and the input image and 
generates control signals which cause adjustment of the 
settings of the optical means. The process is repeated 
automatically until the match is sufficiently good. The 
invention can also be operated in a manual, man-in-the­
loop mode.

signals über einen Oszillator (16a), dessen Steuersignal aus der Abkling­
dauer des Fluoreszenzsignales abgeleitet wird. Auf diese Weise werden 
erheblich bessere meßtechnische Eigenschaften erreicht als bei der be­

Title: Interface circuit with transient event tolerance
IPC: H05K1/02
Filed: 1990-02-15
Abstract: An interface circuit provides for coupling of 
communications signals between a conductor of a transmission 
path, and a key telephone system and provides for protection 
against electrical energies, as may be associated with 
transient electrical event occurrences along the transmission 
path. The interface circuit provides for coupling of some of 
these transient electrical energies from the transmission 
path conductor to an earth ground. The interface circuit 
includes a plurality of electrical components and a 
plurality of electrical conductors being fixed to the surface 
of a sheet of electrically insulating material. Each of the 
electrical conductors is bounded by a peripheral edge, the 
peripheral edge of each conductor being spaced apart from the 
peripheral edge of any other conductor by at least a first 
predetermined amount. Some of the electrical conductors 
connect the electrical components of the interface circuit in 
a workable arrangement whereby the communications signals may 
be coupled. First and second ones of the electrical 
conductors are for connection to the earth ground and the 
transmission path conductor, and in combination are arranged 
to provide a coupling path for said some electrical energies. 
The coupling path comprises first and second terminating edge 
portions within each of the peripheral edges of the first and 
second ones of the electrical conductors respectively. The 
terminating edge portions are arranged in juxtaposition with 
the surface of the sheet and spaced apart one from the other 
by a second predetermined amount being less than the first 
predetermined amount.

Abstract: In a coder for digital video signals, the difference between the ditigal video signals and prediction signals is subject to a transform prior to quantisation. In particular, a transform applied to the values of a block of pixels to produce sets of coefficients in the spatial frequency domain.

The coder further includes means (20) for adding the prediction signal to the output of the local decoder (18) and a framestore (22) which receives the output of the adding means (20). A multiplier (26) multiplies the output of the framestore (22) by a factor slightly less than unity to form the prediction signal.
