Abstract: ABSTRACT OF THE DISCLOSURE           A digital conversion system for a color video signal comprising a system which selectively converts an analog composite color video signal and analog primary color video signals to digital signals includes:  a matrix circuit (17) which forms a luminance signal and first and second color difference signals from the input analog primary color video signals, and a switching circuit (18) which converts the first and second color difference signals to a sequential color difference signal.  A switch (28) selects the luminance signal from the matrix circuit (17) or the input NTSC analog composite color video signal.  A first analog to digital converter (411 receives an output from the switch (28); and a second analog to digital converter (42) receives the sequential color difference signal.  A digital composite color video signal or a digital luminance signal is obtained from the first analog to digital converter (41), and a digital line sequential color difference signal is obtained from the second analog to digital converter (42).          The line sequential chrominance signal can be digitized by a single inexpensive A/D converter which has a slow processing speed, so as to produce an inexpensive digital conversion system which is small.

Abstract: Heating Device for Utilizing the Skin Effect of Alternating Current ABSTRACT    An improved power cable for a heating system that utilizes the skin effect of alternating current, and a method and apparatus for joining lengths of the improved cable.  In one embodiment, the cable includes a stranded copper conductor (20) surrounded by a semiconductive layer (22) formed by carbonized tetrafluoroethylene (TFE) tape which is surrounded by a primary insulation layer (24) formed by pressure extruded, perfluoroalkoxy resin (PFA), the thickness of which is determined by an equation that considers the eccentric positioning of the power cable in a heat tube (14).  In a second embodi-ment, the cable comprises a central conductor (30) sur-rounded by a semiconductive layer (32), followed by a primary insulation layer (34) formed by pressure extruded PFA.  A shield layer (36) formed by a layer of semicon-ductor material (38) and several helically wrapped drain wires (40) surrounds the primary insulation layer.  A protective PFA jacket (42) is pressure extruded over the shield layer.  Lengths of the improved cable are joined by first removing predetermined portions of the insulating and semiconductor layers from a terminal end (50) and a feed end (52) of respective cable lengths.          The exposed conductors (30') are mechanically joined and covered by a spirally wrapped carbonized TFE tape (60).  An insulating layer (62) is formed over the junc-tion by spirally wrapping uncured, nonadhesive tetra-fluoroethylene tape with a 50% overlap and then heat fusing the layer. Shield extensions (66), (68) are formed by spirally wrapped, carbonized TFE tape that extend into noncommunicating, isolated overlapped rela-tionship from the respective shield layers (38) of each cable end.  The entire splice is covered with a layer of insulation (73) formed by uncured, nonadhesive TFE tape which is subsequently heat fused.  The drain wire (40) from the terminal end is grounded to the heat tube.

Abstract: Abstract:     In a method of deflecting forces, in particular loads, either a force acting on a guide surface is reduced and simultaneously deflected by a counter-force or a pressure force is allowed to act on a guide surface to produce a deflecting force.  For reducing the frictional resistance of the force on a support on which it acts, this force can be reduced by a counter force and then the force can be deflected.  The counter-force is produced by a diaphragm chamber or a piston.  A portion of the force is deflect-ably supported on a wedge surface.  This method permits an advantageous deflection of forces, in particular of loads against friction forces.

Abstract: ABSTRACT An oversampling technique for converting an analog signal to a digital signal is described.  Firstly, an input analog signal is oversampled at a first frequency higher than the Nyquist frequency to produce a sampled signal.  Then a local decoded signal is subtracted from the sampled signal. The subtracted signal is then quantized into a quantized binary signal.  The local decoded signal is generated by integration of the quantized binary signal.  The quantized binary signal having the first frequency is converted into a frequency-reduced signal having a second frequency which is then integrated to provide a converted digital signal.  High precision linear coding is achieved by the invention.

Abstract: METHOD OF GENERATING FINITE ELEMENTS  USING THE SYMMETRIC AXIS TRANSFORM                 ABSTRACT OF THE DISCLOSURE            A method,  amenable to automation,  for generating finite elements of a geometric model.  The model is  first subdivided into coarse  subdomains  and then the coarse subdomains are further subdivided. The coarse subdivision is performed using a sym-metric axis transform which generates axes sym-metric to opposing boundaries of the object.  The transform also generates a radius function of the axes giving the distance between the axes and the boundaries.  A coarse subdomain is created between each single non-branching section of the axes and one of its associated boundaries.  The fine  sub-divisions  of the relatively simple  coarse  sub-domains is performed by well known techniques or can beneficially use the radius function.

Abstract: ABSTRACT An apparatus for processing a digital signal which is transmitted from a transmit station by a radio equipment and contains the same repetitive information employs the principle of decision by majority. A particular signal pattern with the least error rate is determined by majoiry. Noncoincident bits between the determined signal pattern and each of the repeatedly received patterns are counted and, then, the number of noncoincident bits is determined on each of a predetermined number of patterns which are selected by a selector out of the repeatedly received ones. When the number is smaller than a predetermined one, the pattern is allowed for processing. That is, the signal pattern is processed by measuring the bit error rate in a transmission path with the signal pattern equivalently used as a reference.
