Abstract: In a method of regenerating a carbon slurry (14) used to produce a black matrix-type phosphor screen of a cathode ray tube, excess carbon slurry is collected (21) after the completion of carbon-coating of a cathode ray tube panel (11) and the collected carbon slurry is regenerated by means of an ion-exchange resin. The method can be employed in an apparatus for producing the screen, the apparatus including a nozzle (17) for coating the slurry (14) on the panel (11), a tank (13) containing the slurry, a supplying system (16) for supplying the slurry from the tank to the nozzle, a collecting system (21) for collecting the excess slurry produced from the nozzle back into the tank, and a carbon slurry regenerating device (24) using the ion-exchange resin. The regenerating device (29) can be placed in at least one of the supplying system (16), the collecting system (21) and the tank (13).

Abstract: Method of manufacturing biaxially stretched thermoplastic tubes using an installation which has a plastics extruder with open-loop or closed-loop control of its output and with a die head for extruding a high-viscosity initial tubing, a stretching mandrel and a speed-controllable take-off unit. In the region of the take-up part there is arranged a surrounding temperature-control bath for adjusting the temperature of the tube to stretching temperature, in the region of the take-off part there is arranged a cooling bath. In the region behind the cooling bath there is arranged a Raman spectrometer, which operates with laser waves. The frequency of the laser waves is adjusted appropriately for the plastic used and the energy of the laser waves is adjusted appropriately for the wall thickness of the tube produced, in such a way that the tube radiates not only the wave radiated in and scattered or reflected by the plastic but also at least one wave corresponding to a Raman spectral line. The degree of axial orientation of the molecules of the plastic is determined from characteristics of the wave scattered or reflected and/or radiated from the tube.

Abstract: Methods are described for producing a needle probe tip having prescribed magnetic properties for a scanning magnetic force microscope (MFM) on a substrate positioned in an evacuated environment. A substantially rigid, nanometer-scale needle-like structure is produced by selective decomposition of a volatile organometallic compound by a highly focussed electron beam. Processing steps are described to obtain the prescribed magnetic properties of such a needle probe structure; in particular, the fabrication of a single magnetic domain, with hard or soft magnetic properties at the distal end of the needle structure. These magnetic sensing probes allow magnetic imaging at the nanometer-scale level.

Abstract: A dynamic programming or DP matching system for speech recognition in which upon DP matching, cumulative distance is compared with a threshold value at every sampling time point of speech pattern for thereby restricting the number of DP paths in the succeeding matching process. The number of DP paths remaining at each speech pattern sampling time point is monitored by a monitoring module (15) for altering a threshold value for decreasing the number of the DP paths. When the DP Path number becomes excessively large, the threshold is increased to thereby decrease the DP path number. Capacity of a DP data storing memory (11) can be reduced while preventing the matching capability from being lowered.

Abstract: A process for starting-up in a desired forward sense of rotation a multiphase, brushless, sensorless, DC motor, while limiting then extent of a possible backward rotation, consists in exciting a predefined phase for accelerating the rotor toward a relative equilibrium position for a fraction of the time necessary to the accelerated rotor to travel through a nearest angular position which would determine a "zero-crossing" in the waveform of any one of the back electromotive forces (BEMFs) which are induced by the rotor on the windings of the motor. After the elapsing of this brief impulse of excitation, the sign of the BEMFs induced in the windings of the motor are digitally read thus producing a first reading. The occurrence of a first "zero-crossing" event if monitored and if this happens within a preset interval of time subsequent to the instant of interruption of the first excitation impulse, the optimal phase to be excited first for accelerating the motor in the desired direction is confirmatively decoded through a "look-up table" and the start-up process may proceed. If such a "zero-crossing" occurrence is not detected within said period of time, the routine is repeated by exciting a different phase which is functionally shifted of two phase positions from said predefined phase. The maximum backward rotation that may occur in the worst of cases is sensibly less than the angular distance which separates two adjacent equilibrium positions of the rotor and in practice may be of just few degrees.

Abstract: Improved rape plants, seeds capable of forming the same, and a novel improved vegetable oil derived from the rapeseeds are provided. Such plants have the ability to yield a vegetable oil of increased heat stability in combination with other desirable traits. The increased stability of the vegetable oil is attributable to the presence of an unusually high oleic acid content in the rapeseeds which has been lacking in the available rape plants of the prior art. It has been found that the novel rape plants of the present invention reliably can be formed by mutagenesis followed by selection as described. The vegetable oil produced by the improved rape plants of the present invention is particularly well suited for use as a frying oil wherein the increased stability at elevated temperatures is of prime importance. In a preferred embodiment wherein the vegetable oil is used as a frying oil, the alpha-linolenic acid content concomitantly is reduced which additionally imparts an increased oxidative stability.
