摘要： The invention relates to methods and devices for controlling the access to a data processing system, especially a data memory, by means of an access filter circuit (10). In the event of unlimited access, said access filter circuit (10) is operated at a normal operation temperature in a read-write mode, and in the event of limited access, is operated at an access protection temperature which is lower than the normal operation temperature.

摘要： In the method proposed, microparticles suspended in a liquid or droplets suspended in a liquid with which they are immiscible are shaped by high-frequency electric fields in a three-dimensional electrode array (11a, 11b, 11c, 11d, 11e, 11f) of a size in the micrometre or submicrometer range and subsequently consolidated by prior art chemical bonding procedures or by physical methods. The disposition, geometry and control of the electrodes determine the shape of the particles. The particles themselves must have a conductivity and/or relative dielectric constant lower than the solution surrounding them. For some, this can be achieved only at certain frequencies in the kHz and MHz band which are determined by the passive electrical properties of the particles and the surrounding solution. The particles or droplets are repelled by the electrodes so that they are shaped in the free solution without making contact with any surface and can then be consolidated. This makes it possible to shape micrometre- and submicrometre-size particles of the kind required in chromatography, affinity biochemistry and medicine, as well as for filter systems.

摘要： The invention concerns motors in which the torque is produced not by magnetic fields but by dielectric forces. Fields of application are microelectronics and micromechanics. The rotors consist of several dielectrics (2a, 2b) arranged in sectors or disks or which partly or completely surround each other. These motors can be miniaturized to a few νm in size. They are characterized by slow to medium rotational speeds, short start-up phases (ms range and less), extremely low current consumption, simple construction and high running constancy and require virtually no maintenance. The rotation characteristic curve (rotation as a function of field frequency) can be freely chosen within wide limits by variation of the rotor dielectrics (2a, 2b).

摘要： Un élément micromécanique diélectrique, dont la partie mobile (2) (appelée ci-dessous rotor) est un diélectrique homogène ou hétérogène, a des applications dans les domaines de la microélectronique, de la micromécanique, etc. Cette partie mobile (2) est entraînée par un ou plusieurs vecteurs de champ électrique générés par des tensions commutées au moyen d'agencements d'électrodes et/ou par excitation des électrodes (4a-h, 5a-h) au moyen de tensions déphasées. Les électrodes (4a-h, 5a-h) forment au moins d'un côté du rotor (2) et/ou à l'intérieur du rotor (2) une rangée linéaire ou courbe d'électrodes. Une ou plusieurs électrodes (4a-h, 5a-h) peuvent former des contre-électrodes communes pour une ou plusieurs électrodes individuelles.

摘要： The description relates to a process for separating mixtures of microscopically small dielectric particles in suspension and a device for implementing the process. Prior art separation processes separate particle mixtures according to the differing mobilities of their components. This requires extensive measures to suppress convection in the suspension. In the process of the invention, the particle mixture is forced onto tracks by dielectrophoretic forces or by the flow of the suspension medium. An additional force which, for specific particle types, offsets the force driving the particles onto tracks, separates particles of these types out of the mixture. The device for implementing the process is suitable for system integration. It can be integrated on surfaces of silicon wafers economically and in large numbers. The device is suitable for isolating small particles like biological cells, cell organella, bio-molecules and organic dielectric particles.

摘要： The description relates to a process for manipulating microscopically small dielectric particles in which the particles are exposed to an electric field. In prior art processes the particles are exposed to non-uniform electric fields are polarised thereby. The polarised particles are moved towards higher field intensity. These processes do not permit the reversal of the direction of movement of the particles. The particles are enriched at the electrode and cannot therefore be held in free space. In the process of the invention the particles are exposed to one or more high-frequency fields moving in predeterminable directions whereby a force is exerted on the particles which puts them into a movement strongly asynchronous to the field. With the aid of a device for implementing the process of the invention it is possible very flexibly to manipulate particles. The particles can be moved by means of linearly or circularly arranged electrodes in any direction and through branched microstructures, they can be separated according to their dielectric properties and held contactlessly. The applications lie in the field of biotechnology and molecular separation, focussing and microtransport technology.

摘要： A dielectric motor driven by electric fields comprises two or more dielectic rotors arranged in a central region surrounded by several electrodes. The rotors can be made of different dielectric materials and can be designed so that they are rotationally asymmetrical electrically. They are driven by continuously or discontinuously rotating electric fields. Depending on the geometry and electrical design, it is possible to obtain very varied rotational conditions which can be simply controlled by varying the frequency of the rotating fields. The motor is suitable for switching and driving purposes and can be used in the construction of microdosing devices, pumps and valves.

摘要： Selon un procédé de manipulation de particules diélectriques de dimensions microscopiques, les particules sont exposées à un champ électrique. Selon des procédés connus, les particules sont exposées à des champs électriques inhomogènes et sont polarisées par ceux-ci. Les particules polarisées se déplacent dans la direction où l'intensité du champ est la plus élevée. Ces procédés ne permettent pas de renverser le sens de déplacement des particules. Les particules s'enrichissent au niveau de l'électrode, de sorte qu'elles ne peuvent pas être retenues dans un espace libre. Selon le procédé décrit, les particules sont exposées à un ou plusieurs champs de haute fréquence se déplaçant dans des directions prédéterminables, de sorte qu'une force est exercée sur les particules qui les met en un mouvement fortement asynchrone par rapport au champ. Un dispositif de mise en oeuvre de ce procédé permet de manipuler des particules avec beaucoup de souplesse. Des électrodes agencées en ligne ou en cercle permettent de déplacer les particules sur des voies linéaires dans toutes directions voulues ou à travers des microstructures ramifiées; elles peuvent être triées selon leurs propriétés diélectriques et retenues sans contact. L'invention trouve des applications sans le domaine de la biotechnologie et des techniques de microtransport, de focalisation et de triage moléculaires.

摘要： A dielectric micromechanical element has a mobile part (2) (hereafter referred to as the rotor) which is an electrically homogeneous or inhomogeneous dielectric. Fields of application are microelectronics, micromechanics, etc. This part (2) is driven by one or more electric field vectors which are produced via electrode arrangements by means of switched voltages and/or by driving the electrodes (4a-h) with phase-shifted voltages. The electrodes (4a-h, 5a-h) are disposed in a linear or curved row on at least one side of the rotor (2) and/or in the interior of the rotor (2). One or more electrodes (4a-h, 5a-h) can be designed as common counter electrodes for one or more single electrodes.
