Abstract: An optical recording medium comprising a plastic substrate having a surface of minutely roughened structure and a thin metal film formed on the substrate is capable of strongly absorbing laser light of a specific wavelength region, thereby writing data on the medium. The optical recording medium is characterized in that the thin metal film comprises a metal of the platinum group and a second metal or semi-metal such that the thermal conductivity of the thin metal film is not higher than 80% of the thermal conductivity of the platinum group pure metal. The optical recording medium is, since jitter has been decreased, capable of a high-sensitivity and high-CNR recording.

Abstract: A clamping device (1) (Fig. 1) serves to clamp a workpiece (3) having column or coordinate bores (2) in position. It serves in particular to clamp die plates in position. Clamping elements (5) of the clamping device (1) engage in these column bores (2). By an axial movement, the clamping elements (5) can be expanded roughly radially and concentrically by means of taper surfaces. In the process, the axial clamping movement is coupled to the radial expanding movement so that the clamping element is also displaced in the axial direction during the clamping operation. The clamping elements (5) are mounted on a base clamping plate (4). Provided on the underside of the base clamping plate (4) are locating projections (20) which engage in workholding slots (21) or bores of a machine tool table (6) in an accurately fitting manner. The clamping device (1) results in repetitive, accurate location of workpieces (3) clamped there, so that there is a considerable reduction in the setting-up times with at the same time high positioning accuracy, especially in mass production. <IMAGE>

Abstract: An algebraic recursion process is defined to solve test conditions for sequential and combinatorial logic devices (22). the process is shown to be effective in identifying external pin faults (24,26,28,30), and is valid for in-circuit test conditions. Since only external pin faults (24,26,28,30) are considered, there is no issue of the correspondence of Boolean products to the internal architecture of the device. Processes to identify the fault detection equation (8) and initialization sequence (17) are described and an effective minimization process presented. Functions simple enough to be implemented by logic networks fall within a range which is computionally tractable by the process of the invention.

Abstract: A new process and apparatus for producing carbon black is provided. Carbon black feedstock oil is fed in multiple and separately-controlled streams through nozzles (17) to an input zone (2) of the reactor which is difided into frusto-conical (23) and cylindrical (24) portions. The difference in dwell time of the streams is at least half of one millisecond. The process utilizes such a reactor to give unique carbon blacks which give rise to low hysteresis loss and good wear when used in rubber compounds for reinforcement and particularly in rubber tyres.

Abstract: Insertion of short homoglycine regions behind and, where appropriate, in front of the recognition sequence, which has been extended by an amino acid such as Lys, for blood coagulation factor Xa greatly increases the specificity of this enzyme. In this way, using smaller amounts of factor Xa and in a shorter time, complete, highly specific cleavage is achieved, with new fragments being formed. Antigens which are suitable for the preparation of the corresponding antibodies or directly for diagnostic aids are advantageously obtained in this way.

Abstract: In order to facilitate the positioning of work-piece holders, for example vacuum discs, on a machine table and to prevent damage to the holders during the subsequent machining operation, the work piece is projected full-size in its contour lines, if need be with further machining points, onto the machine table in such a way that the contour line of the work piece coincides with the path through which the tool passes during the subsequent machining operation. The holders or the vacuum discs are positioned inside the contour lines of the projected image and the contour lines become visible on the work piece guided above the holders or vacuum discs, so that this work piece can be positioned in such a way that little scrap results.   <IMAGE>

Abstract: Disclosed is a compact, wide-range acoustic apparatus which can perform lower bass sound reproduction and is free from noise or distortion components. Spatially separated first and second chambers are formed. The first and second chambers communicate with each other through a port, so that the first chamber and a resonance port constitute a Helmholtz resonator. An open port is formed in or a passive vibrating body is arranged on the outer wall surface of the second chamber, so that the second chamber and the opening or the passive vibrating body constitute an essential low-pass type acoustic filter. A vibrator is attached to the outer wall surface of the first chamber, so that the Helmholtz resonator is driven at the inner surface side of the vibrating body of the vibrator, and an acoustic radiation is directly performed from its outer surface side. The vibrator is driven to cancel an air counteraction from the resonator when the Helmholtz resonator is driven. A cutoff frequency of the acoustic filter is set to be higher than a resonance frequency of the Helmholtz resonator and to be lower than the open duct resonance frequency of the resonance port.

Abstract: A composition for radiation crosslinking is based on a fluorocarbon polymer (such as tefzel) that can be melt fabricated and has a melting point or softening range above 200°C. A polyunsaturated crosslinking promoter (such as TAIC) is used, and an anti-oxidant (such as hydroquinone) is added in an amount sufficient to substantially prevent any oxidative polymerisation of the promoter at temperatures at least up to the melting point/softening range of the polymer for a minimum of 15 mins. Surprisingly the quantities of anti-oxidant required to substantially eliminate oxidative polymerisation do not prevent radiation crosslinking of the composition nor seriously reduce its efficiency.

Abstract: A die cutting press and a method of die cutting include two opposing and oppositely driven clamping bars (22,24) which move together to clamp the die board (14) and accurately position the clamped die board (14) at a predetermined location within the press. The press is operated to determine the adequacy of the cut produced by the die (15) in sheet material fed into the press. If the cut is unsatisfactory, the opposing clamp bars (22,24) are quickly driven apart thereby releasing the die board (14). The die board (14) can be removed from the press and then manipulated or modified to cure any imperfection in the cut. The modified die board (14) is then reinserted into the press and accurately repositioned at the predetermined location within the press by driving the opposing clamping bars (22,24) towards each other against the die board (14). The drive mechanism (21,23) of the clamping bars (22,24) ensures that when the die board (14) is securely clamped, the die board (14) will always be accurately repositioned in the same press at exactly the location assumed by the die board (14) when it was inserted. The opposing moving clamps (22,24) automatically move the die board (14) to the predetermined position without the need for measurement, registration or concern for variations in tolerances within a jig.
