Abstract: The portable electronic computer for fraction calculation comprises a display (1) including a first multiple-digit display area (1c) for displaying the numera­tor of a fraction, and a second multiple-digit display area (1d) for displaying the denominator of the fraction. The numbers of digits of the numerator and denominator of a fraction to be displayed are obtained. The number of digits of the numerator is compared with the number of digits of the denominator. The difference between the number of digits of the numerator and the number of digits of the denominator is calculated. When the number of digits of the numerator is smaller than the number of digits of the denominator, the numerator is displayed on the first display area (1c) with its position shifted to an upper digit place according to the dif­ference. When the number of digits of the denominator is smaller than the number of digits of the numerator the denominator is displayed on the second display area (1a) with its position shifted to an upper digit place according to the difference.

Abstract: Subblocks of input digital samples are stored into a buffer at frame intervals and segmented into blocks having an integral multiple of the length of the subblock. Each block is encoded into transform coefficients and stored into a memory. Each coefficient is squared and those of the squared transform coefficients which correspond to high-frequency components of the input digital samples are summed and a minimum value is detected therefrom as corresponding to an optimum block length. Those transform coefficients which correspond to the optimum block length are selected from the memory and multiplexed with a signal representative of the optimum block length. In a modification, interblock differences are detected between successive transform coefficients of equal block length and squared. Those of the squared interblock differences which correspond to equal block length are summed, producing a set of squared sums for each block length. A variation is detected between a representative squared sum of a given set and a representative squared sum of a successive set to identify a block length which corresponds to the variation as an optimum block length.

Abstract: Distortion in a digital-to-analog converter (DAC) is eliminated by adding a digital random number to each sample of the digital signal, converting the sum into analog form, and subtracting from this analog sum the analog counterpart of the digital random number. The result is the analog counterpart to the input digital signal. The conversion of the summed digital signal and the random number into analog form can be performed by two conventional DACs (18,24). For any digital input sample, the output of each DAC is equally likely to contain any of the possible distortion errors produced by that DAC. (An exception is the most significant output bit of the DAC that processes the summed signal, an exception that may be handled by stripping off the most significant bit and applying it to a one-bit DAC (26).) The error signal at the output of each of the two DACs is thus a random sequence (i.e. noise) of DAC distortion errors. The time average of this noise signal is a small offset error which, if desired, can be removed by subsequent processing stages.

Abstract: A method for classifying and accessing a collection of documents as a single document entity. Relationships are formed between the collection of documents in a relational manner. Each individual document relationship is assigned a document relationship classification independent of the document. The relationship classification contains sensi­tivity attributes in addition to specific information which relates the documents to a part of a particular set. Access to documents is based on the requester's creden­tials as well as a calculated relationship classification based on the sensitivity attributes.

Abstract: High-voltage circuit breaker of self-blasting type with a gas reservoir for arc extinction consisting of two parts, a pressure storage volume (6) and a puffer volume (7). The two volumes (6, 7) are separated by a wall (11) with a non-return valve (12,13,14) which is closed when the pressure in the pressure storage volume (6) is higher than in the puffer volume (7). During an opening operation, the gas in the puffer volume is compressed because the distance between the wall (11) and the puffer piston (16) then decreases. The invention improves the breaking capacity on the occurrence of a breaking operation immediately following an auto-reclosing by arranging the puffer piston (16) axially displaceable against the action of one or more springs (17). During the high-pressure phase in the first breaking operation the piston (16) is moved against the resistance of the springs 17 and, when the pressure drops towards the end of the movement, a gas puff is injected into the pressure storage volume under the force of the re-expanding springs 17. This results in a considerable reduction of the gas temperature in the pressure storage volume which in this way achieves in better condition for the next breaking operation.

The reagents are prepared by covalently attaching biologically active substances, for example antibodies, to the particles, directly or indirectly through reactive groups on the particle surface. These reagents are used to advantage in analytical elements and methods for the detection of specific binding ligands (such as immunological species) and immunoassays, and in purification methods as affinity chromatography reagents. Adsorption of undesirable proteins on the particles of the reagents was considerably reduced because of the specific composition of the particles.

Abstract: In a "piggy-back" head support system, a fine actuator (46) which carries the head (lens or transducer) is controlled to move the head. A coarse actuator (36) or headarm movably supports the fine actuator and is mounted on a frame (35) for movement radially of the signal storage disk (30). The head scans tracks on the disk. A servo actuates the coarse actuator to follow the movements of the fine actuator. In a seek, the coarse actuator may not be able to follow the fine actuator resulting in the fine actuator hitting a safety stop. When this happens, seek errors occur. According to the invention, the relative displacement of the fine actuator with respect to the coarse actuator is limited during predetermined portions of a seek operation, i.e. the high speed accelerate and decelerate portions.

Abstract: Disclosed is a method of fabricating a microelectronic package (1) having least one layer formed of a Cu-Invar-Cu core (11) encapsulated between a pair of dielectric films (21). The package is intended to carry surface circuitization (31) on an external surface, with internal circuitization from the surface circuitization passing through the core. The method includes contacting the copper within the Cu-Invar-Cu core with a copper etching aqueous solution of a strong base and a strong oxidizing acid, while maintaining the copper anodic. This electrolytically converts the copper to soluble copper oxides. In a separate step the Invar of the Cu-Invar-Cu core is electrolytically etched with an Invar etching aqueous solution of sodium chloride. This step is carried out under conditions to electrolytically form soluble iron and nickel chlorides while passivating the copper.
