Abstract: Computer-controlled apparatus for the automatic delivery of fuel, liquified gases or other fluids from a tanker into the tanks of the consumers, using a computer provided on board the tanker, and a control unit which is actively connected to the computer via an interface and has two power outputs for controlling electrovalves, information signals on the amount of delivered fuel or liquified gas, as well as data regarding the operating state of the engine (engine on/engine off) being fed to the control unit. In order to guarantee the greatest possible functional reliability, an optical sensor, to which a rotating disk provided with recesses and an optically conductive fibre cable for the advance and return of the optical signals are assigned, is used for measuring the delivered fluid. Furthermore, in order to avoid additional calibrations, the sensor is arranged on an extension of the shaft of a calibrated, mechanical volume-measuring apparatus of the tanker. A thermal electric detector is provided, which is likewise actively connected to the control unit in order thereby to guarantee greater accuracy in the measured-volume acquisition. The apparatus permits the recording of statistical values for the individual supplying and delivering operations. <IMAGE>

Abstract: In a sensor (12) for determining pressure or force a thick-film resistor (11) is pressed onto a carrier (10). When the thick-film resistor (11) is still in the soft state, a force-introducing part (13) is placed onto the thick-film resistor, and the component thus produced is hardened. As a result, a sensor (12) having a virtually uniform load distribution over the entire thick-film resistor is produced, so that its pick-up curve is already linear in the initial range without prestressing. <IMAGE>

Abstract: The invention is directed to an inference mechanism to execute human logical and fuzzy thought including intuitive thought. The mechanism consists of two independent engines. One engine is a conventional inference engine based on human logical thought. The other engine is a fuzzy reasoning engine based on human fuzzy thought. The mechanism utilizes a common domain control to connect the two engines. After reading in the domain by the fuzzy reasoning engine, the engine draws inferences and writes the fuzzy reasoning result. The conventional inference engine operates in accordance with the results in the domain. 
     For intuitive thought, for example, a model is introduced for realizing an operation or a situation of an object. The conventional engine commences execution of the model. The model predicts objectives states under a present condition and outputs a predicted performance value requiring fuzzy reasoning on the domain.

Abstract: A nitrogen-containing Fe-based soft magnetic alloy suitable for use as the material of a magnetic head core, as well as a method for manufacturing the soft magnetic ally film. Unlike a mere nitride alloy film, the soft magnetic alloy of the present invention has a compositionally modulated structure in which at least the nitrogen content is periodically modulated in the direction of thickness of the film so as to have a nitride layer rich at least in nitrogen and a non-­nitride layer poor at least in nitrogen. The soft magnetic alloy film of the invention comprises a main constituent of Fe, at least one metalloid element selected from the group consisting of B, Si and C, and at least one metal element selected from the group consisting of Nb, Ta, Zr and Ti and has fine Fe-based grains included therein. By virtue of these film struc­ture and film composition, the soft magnetic alloy film of the invention exhibits superior magnetic character­istics such as low coercive force, high saturation magnetization and low magnetostriction, as well as superior resistance both to corrosion and wear. The method of the invention is for forming the soft magnetic alloy of the invention, and has the steps of forming by sputtering a compositionally modulated nitride ally film, and then effecting on the compositionally modu­lated nitride alloy film a high-temperature heat treat­ment so as to cause a change in a film structure to form the soft magnetic alloy film.

Abstract: A high-speed test system for semiconductor integrated circuits utilizes electro-optic sampling techniques to perform tests at data rates up to 1.2 Gb/s. The receiver portion of the tester has a 4.5 GHz bandwidth and can perform ECL level functional test with one sampling pulse per vector. A device under test is positioned in a test head (11) with an electro-optic birefringent cystal sensor (34) positioned below the device under test to minimize signal path length. A system control unit includes a Nd: YAG mode-locked laser (22) which generates optical pulses, and optical transmission means (38) directs the optical pulses to an array of reflective contacts (74) on the sensor (72). The sensor (72) functions as a Pockels cell with the electric field in the crystal sensor (34) due to voltages on the array of contacts (74) changing the transmission of polarized light through the crystal. Reflected pulses are received and converted to electrical signals indicative of the voltages on the array of contacts (74) on the electro-optic sensor (72).
