    摘要: A device for determining motion parameters includes a magnetic multipole that generates an alternating magnetic field, at least one magnetic sensor for measuring the magnetic field of the magnetic multipole, and an evaluation and control unit for evaluating the signals from the magnetic sensor. The magnetic sensor includes a magnetizable core, a drive coil, and a measuring coil. The evaluation and control unit charges the drive coil with a periodic drive signal so as to bring about a periodic magnetic reversal of the core and detects the points in time at which the magnetic reversals occur in the core. Based on the points in time at which the magnetic reversals occur, the evaluation and control unit determines a current value of the effective magnetic field of the magnetic multipole within a defined measuring range representing a range around a zero crossing of the magnetic field of the magnetic multipole.

    摘要: An angle sensor for determining a rotation angle of a rotatable body, such as a steering column in a motor vehicle, includes a gear wheel. The orientation of a magnetic field generated by the gearwheel is configured to be detected by a magnetic field sensor. The gear wheel is comprised of a magnetisable material, such as hard ferrite, into which a magnetization is introduced. The gear wheel is stronger in a central region than in an edge region in which the teeth are arranged. In order to weakly magnetize the edge region, which minimizes a negative influence of the teeth on the homogeneity of the generated magnetic field, the front face of the gear wheel is configured to be magnetized. The magnetization process advantageously takes place at the same time as an injection moulding process to form the gearwheel. A method is implemented to produce the gear wheel.

    摘要: A stripline laser wherein the distance between a mirror and a stripline is minimized without modifying the characteristics of the laser is provided. The stripline laser prevents damaging of the mirror due to plasma discharge by providing at least two insulating strips arranged between oppositely polarized electrodes. Electrically conductive paths lie between the insulating strips. The insulating strips are arranged to guarantee a voltage division. The voltage division maintains the voltage of the electrically conductive path neighboring the mirror below a plasma-maintaining voltage.

    摘要: In a gas laser having a capillary and a cathode that envelopes the capillary, a fastening of the cathode suitable for batch soldering is achieved in that the cathode is secured to an end piece having a mount for an optical element, and an end of the cathode facing away from the end piece is elastically supported against a housing wall with such a slight spring power that a weight of the unit formed of the cathode, end piece, and mount is adequate for overcoming the friction between the spring and the housing wall. Thus, the end piece with the attached cathode can slide into its final position during soldering solely on the basis of the force of gravity. The invention is particularly suited for helium-neon lasers that are manufactured in glass solder technology.

    摘要: In order to bring about durable solder joints on transparent thin film electrodes which themselves are not solderable, the conductive layer is treated as follows. First, the conductive layer is applied in a vacuum and, more specifically, in the fully oxidized state, and then a solderable layer is generated on the conductive layer in the same vacuum. The electrode consists preferably of an indiumtin oxide and the solder layer consists of copper. The proposed coating technique is particularly simple since the solder layer requires neither an adhesion aid nor a corrosion protection layer. If it consists of copper, it can withstand without difficulty, if it is thick enough, even small thermal stresses such as occur for instance in the fabrication of liquid crystal displays with cementing frame.The layer system is particularly well suited for the electrode leads of electro-optical displays such as liquid crystal displays.

    摘要: An indicator device which has two sealed chambers which are formed by at least one carrier member interposed between a pair of glass plate members to provide a tandem arrangement in the direction of travel of light in the device, characterized by at least one of the chambers containing a liquid crystal layer and being provided with transparent conductive material on the walls thereof to form a liquid crystal cell. In one embodiment one liquid crystal cell is a rotation cell and the other is a DAP cell which cells can be activated to give multi-colored indications. In a second embodiment of the invention, one of the cells is a rotation cell and the other is a polarizing cell which enables giving a colored indication on a colored background or a white indication on a black background. In a third embodiment, both cells are rotational cells with a different angle of rotation and the carrier member consists of a birefringent material which enables indications of at least four different colors. In a fourth embodiment, each conductive layer of each cell is separated in two parts by a continuous interruption in the layer so by selectively applying voltage to different parts, at least four different symbols or shapes can be indicated. In a fifth embodiment, each of the cells is a rotational cell of approximately 45.degree. and the electrode pattern of each cell is a matrix of strips extending perpendicular to each other so that the time required for indicating an image on the device is reduced. In a sixth embodiment, the conductive layers of each cell are arranged as a segment electrode pattern with the segment being subdivided into partial segments with one partial segment being in one cell and the remaining partial segment in the second cell to enable determining errors in actuation of various segments during an indication. In a seventh embodiment, the liquid crystal cells are arranged in tandem one behind the other so that either by separately actuating the electrodes of each cell a sign or symbol can be produced without undesirable cross points or by sequentially activating the electrodes of each cell, a partial image can be produced in each cell to create a moving image on the device. In the eighth embodiment, one of the cells is provided with a reflective layer by either depositing from a silver-ammonium complex or by printing with a silver compound onto a surface of the chamber to provide a reflecting chamber which enables operation of the remaining cells in a reflective mode. In a final embodiment, an electrochemical luminescence layer is provided in one cell to provide an illuminating background for indications produced on the other cell.
