Abstract: Resin compositions containing vinyl polymers and olefin polymers for use in electrophotography, electrostatic recording and electrostatic printing are obtained by adding and mixing the olefin polymer into a solution of the vinyl polymer and thereafter removing the solvent under a reduced pressure of 0 - 266 mbar absolute, thereby achieving a uniform dispersal of the olefin in the vinyl polymer. A toner can be obtained by mixing a colorant and a charge control agent with the resin, the latter comprising 30 - 95 parts by weight of the toner.

Abstract: A method and apparatus are disclosed which provide for the removal of distortion present in a digital output signal from a linear analog signal processing system. Two applications are disclosed: digital compensation and digital equalization. Digital compensation provides for the removal of distortion from a single signal processing system. In particular, an adaptive digital filter operates to provide processing of an output signal from the signal processing system in accordance with correction criteria determined by a controller in response to a training signal. Digital equalization is employed with respect to a plurality of signal processing systems, and provides equalization of an output signal from one signal processing system in accordance with characteristics of a selected signal processing system. In particular, output signals from a selected signal processing system and a signal processing system desired to be equalized are employed to provide information to a controller for use with a correction criteria in the determination of correction information. The correction information is used to direct an adaptive digital filter coupled to an output of the signal processing system which is desired to be equalized.

Abstract: A high-mobility semiconductor device having a GaAs/AlGaAs hetero junction comprises a GaAs active layer (5) 10-300 nm thick and a GaAs contact layer (9), 50-300 nm thick with a high-carrier concentration AlGaAs barrier layer (7) 5-30 nm thick interposed therebetween. These layers are formed by epitaxial growth on a semi-insulating GaAs substrate (1) bearing an AlGaAs buffer layer (3), at least 500 nm thick. On the contact layer are attached a source electrode and a drain electrode; a gate electrode is formed in the contact layer by selective etching. 
     The effective carrier concentration of the active layer is increased by the barrier layer and the thick­ness of the active layer is reduced, resulting in an increase in the trans-conductance and improvement in the high frequency characteristics. Since the presence of the barrier layer enables selecting etching of the contact layer, element characteristics such as the plane uniformity and reproducibility can be improved.

Abstract: The method for manufacturing pliable objects, such as book covers, folding containers or the like by welding plastic films with reinforcing liners interposed employs a welding apparatus which permits the use of halogen-free thermoplastic films and has a welding tool which can be heated to the desired welding temperature and a counter-tool which can be set to a temperature below the melting temperature of the films and has a profiling corresponding to the desired welding or embossing contour, in particular a cutting edge, as well as a heat-conductive release foil which can be introduced into the welding apparatus, through which the thermal energy required for plasticising the films can be supplied to them and from which the films can be detached after they have cooled. After drawing in and fixing an outer cover film, which faces the counter-tool heated to a temperature lying in the temperature range of film softening, but below the film melting temperature, a vacuum is generated in the flat hollow formed by the counter-tool in order that the reinforcing liner is laid in this flat hollow, lined by the cover film; the inner film, away from the counter-tool, and the release foil are laid on the hollow, the heated welding tool is moved in the direction of the counter-tool, the welding tool is returned once welding has been completed and, depending on weld cooling, first of all the release foil is detached from the weld and then the film/reinforcing liner unit is detached from it once the vacuum has been removed from the hollow of the counter-tool. <IMAGE>

Abstract: A method and apparatus for improving the operation of a switched reluctance motor at low speed incorporates an advance angle regulator which regulates the firing angle of current pulses to the switched reluctance motor so that over a wide range of speeds and levels for direct current source voltages, the winding current reaches a commanded set point at a commanded angle. The advance angle regulator may comprise a closed loop regulator which includes apparatus for detecting the actual angular position at which motor current reaches a commanded level and adjusts the turn-on angle to shift the angle at which current reaches its desired level to a desired angle. The regulator incorporates a feedforward portion and an integral portion. The feedforward portion is utilized primarily to accommodate situations in which there is no current feedback. The integral portion provides the primary regulation when current is regulated to its desired value. The regulator causes the torque versus current command to have a transfer function which does not depend upon speed or DC source voltage over a wide range of speed, voltage and torque.

Abstract: When a screw fitting element (1) has to be screwed onto a very long bolt thread, this leads to a long assembly time because of the large number of turns. This time can be considerably reduced if the female thread (15) is bisected in the longitudinal direction and the two thread parts (9, 10) are connected to one another by means of a pivoting joint (5). The screw fitting element can be spread apart, pushed up close to the attachment point and then folded up. Subsequently, they must also be held together. This can be done with the aid of a bracket (4) or the like. The screw fitting element parts (7, 8) which exhibit or support the thread parts are connected by means of this bracket. In the effective position of the bracket (4), the thread parts (9, 10) form the female thread (15) which can be screwed on the bolt thread. <IMAGE>
