Abstract: In a device for receiving data which are transmitted by means of radio waves, particularly together with other information items, in which a syndrome, which is used for error finding and possibly error correction, is formed from the received data word and a parity test matrix, several groups of bits of the data word in each case form an address for forming the syndrome. Subsyndromes, stored under the addresses, of the rows of the parity test matrix which are associated with the bits of in each case one group are called up. The subsyndromes are EXORed. <IMAGE>

Title: Parallel optical arithmetic/logic unit
Inventor: FALK R A
IPC: G06F7/53
Filed: 1988-02-26
Abstract: A parallel optical arithmetic/logic unit has inputs from point-light sources (20-23) forming a given spatial pattern corresponding to a given separation of point sources. The spa­tial pattern is presented to a multiplicity of channels by an optical system formed of linear optical elements (30-32, 40-42, 50-52). A static filter (40-42) is provided in each channel which allows energy to pass when it comes from one spatial pattern but attenuates or diverts energy from all other spatial patterns. Thus energy will emerge predominantly from only one channel from each specific spatial pattern sepa­rated by a given separation of point sources. The desired out­put state of each channel may be detected to indicate the re­sults of an optical arithmetic or logic operation.

Abstract: In the forming of metal sheets, coolants and lubricants have hitherto been used which had to be carefully removed before coating of the resulting products. The novel process is intended to allow simplified forming with subsequent coating. The forming of metal sheets is carried out in the presence of a coolant and lubricant which is an aqueous emulsion or solution of a binder or binder mixture, which produces a paint film. The film thus produced on the formed product can be cured or dried immediately afterwards. Manufacture of cans.

Abstract: An improved jitter detecting method and an appara­tus thereof, for detecting a jitter generated in a repro­duced video signal of a VTR or video disc wherein a frequency-modulated carrier of a video signal is recorded by synchronizing the leading edge of a sync signal with the phase of the forefront carrier of a constant frequency carrier train corresponding to a sync tip for every horizontal period at the time of a frequency-modulation, and from the reproduced frequency-modulated carrier the phase-reset constant frequency carrier train is abstracted as a reference burst signal, thereby to be capable of removing a time-base error by detecting a specifie zero-crossing timing of the abtracted carrier burst through a bandpass filter based on the tailing edge of a frequency-modulated sync signal at the reproduction.

Abstract: Precontoured plating, screws, instruments and methods for osteosynthesis. Plates (10-50) according to the present invention take advantage of the fact that human adult craniofacial structure and shape is highly similar among the population. The plates (10-50) are thus preformed, pretempered, precontoured, and precon­figured during manufacture to fit a large proportion of the human adult population. The plates (10-50) consequently require less time during surgery to twist and bend to conform to the skeletal structure and their crystalline and other structural characteristics need not be adversely affected by extensive bending, twisting and shaping in the operating room. The plates (10-50) may be packaged and presented for use on forms which simulate portions of the skull so that their intended craniofacial location is easily recognised by members of the surgical team. Because bone thickness at particular craniofacial skeletal locations is highly consistent in the adult population, appropriate length screws (68) may also be packaged with the plates with which they are to be used, as for instance, by insertion through the plates on the skeletal-shaped packaging form. The packaging also allows the plates to be presterilized to save time which would otherwise be used for sterilizing the plates. Screws (68), screw transport units (78,80) and starters (82, 102, 106) and dispensers (120) for the plates and screws are also disclosed.

Abstract: An electronic package (10) including a first circuitized substrate (11) (e.g., printed circuit board), a second, flexible circuitized substrate (15) (e.g., polyimide), an electronic device (17) (semiconductor chip) and a metallic (e.g., aluminum) heat sink member (19) joined to the first substrate to provide a cover for the package's internal components. A predetermined quantity of liquid material (21) (e.g. wax or oil) is located between a defined surface of the chip and a correspond­ing internal surface of the heat sink member during assembly of the package, this material possessing a surface tension sufficient to create a suction force between the device and heat sink so as to elevate the device in a spaced position from (e.g., above) the first circuitized substrate during said assembly. Should a liquid material such as oil be utilized, this material remains in the liquid state during package operation to continuously provide the defined suction force sufficient to maintain the device at the elevated position. If a material such as wax is used, this material becomes solidified and remains so during package operation to thus maintain the device in elevated position by adhesion. Improved heat dissipa­tion for the package and ease of assembly thereof is thus possible.

Abstract: In order to cool an optical assembly made up of a lens and of at least one optically inactive transparent plate, a cooling gas is circulated, on the one hand, between the lens and the plate and, on the other hand, over the outer face of the plate. A gas (air, N2, He, Ar) at a temperature below room temperature, preferably between +20 DEG C and -80 DEG C, is employed for this purpose. The optical assembly is cooled in order to bring it to an equilibrium temperature before the energy beam, for example the laser beam, is sent through it; the instability due to the swelling of the lens is thus avoided.

Abstract: In order to increase the temperature resistance of thermally shaped articles (2) made of crystallisable plastic, a heat treatment for post-crystallisation is carried out after shaping. This treatment is completed by introducing a positive, dimensionally accurate, cooled mould (12) into the heat-treated article (2). The cooling causes a slight shrinkage of the material to take place, so that the article (2) comes to bear against the cooled mould (12). Consequently, a high dimensional accuracy of the post-heated, temperature-resistant articles is attained. <IMAGE>
