    摘要： An apparatus for contact-free measurement of electrical charge images of the type generated on a storage plate as transmission images by means of electro-radiographic recording methods has a matrix of dynamically functioning probes, such as Kelvin probes, for scanning the effect of the electrostatic induction caused by the image on the storage plate, the outputs of the probes being amplified and supplied to a display device such as a picture screen. The individual probes of the matrix are electrically conductive elements and a mechanical oscillation is generated between the charge image and the probes in the field to be measured either by oscillating the probes or by oscillating the storage plate. The charge amounts electrostatically induced in the probes are tapped as the image signals.

    摘要： A device for detecting at least one substance of a fluid includes at least one piezo-acoustic resonator with at least one piezo layer, an electrode arranged on the piezo-electric layer, at least one other electrode arranged on the piezo-electric layer and a surface section used for sorption of the substance of the fluid. The piezo-electric layer, the electrodes and the surface section are disposed in such a way that electric control of the electrodes leads to an oscillation of the resonator at a resonance frequency which depends upon the amount of the substance which is sorbed on the surface section. The thickness of the pioelectric layer is in the region of 0.5 to 20 μm and the resonance frequency of the oscillation ranges from 500 MHz to 2 GHz. The device is a mass sensor with a piezo-acoustic high-frequency thin film resonator.

    摘要： The invention is directed to a piezo-electric transducer having electrodes that adhere well both to ceramic as well as to plastics and that are composed of intrinsically conductive plastic. The invention is also directed to a method for the manufacture thereof. A conductive polymer layer is produced on the surface of a piezo-ceramic component by chemical or anodic oxidation of a monomer. The monomers are selected from the class of 5-member heterocycles containing sulfur or nitrogen as heteroatom, or aniline, azuline, or derivatives of the said compounds. The components provided with the economical electrodes can be advantageously composed to form sandwich-like transducers having plastic intermediate layers that exhibit good electro-acoustical properties.

    摘要： The invention is directed to an extremely low-capacitance device for shaping an electron beam. The device is based on a ceramic body having a monolithic multi-layer structure. The manufacture of the ceramic body ensues with the assistance of LTCC technology, whereby this method is designationally modified. The body is constructed of pre-sintered ceramic layers whose lateral shrinkage is suppressed. The through apertures of the electrodes for the electron beam are thus arranged exactly coaxially, and the tolerances of the electrode dimensions are decoupled from the shrinkage during sintering. The electron beam of an electron gun is focused and the intensity thereof is modulated with the assistance of such a device.

    摘要： An ultrasound array has a number of oscillator elements arranged side-by-side, each oscillator element having a trapezoidal cross-section. The oscillator elements are separated from each other by incisions having non-parallel walls, which are co-planar with surfaces of the piezoelectric material comprising the oscillator element. The incisions terminate in a damping member, to which all of the oscillator elements are attached. The incisions are produced with an excimer laser whose laser beam is focused onto a prepared layered material, with the incisions proceeding along a line.

    摘要： The invention relates to a glass ceramic mass containing at least one oxide ceramic containing barium, titanium and at least one rare earth metal Rek; and at least one glass material containing at least one oxide with boron, at least one oxide with silicon and at least one oxide with at least one bivalent metal Me2+. The glass ceramic mass is characterised in that the glass material contains at least one oxide with bismuth, especially bismuth trioxide. The oxide ceramic is especially a microwave ceramic of formula BaRek2Ti4O12, Rek being neodymium or samarium. The composition of the oxide ceramic remains essentially constant during the sintering of the glass ceramic, enabling the material properties of the glass ceramic mass, such as permittivity (20–80), quality (800–5000) and Tkf (±20 ppm/K) to be specifically predetermined. The glass ceramic mass is characterised by a densification temperature of under 910° C. and can is therefore suitable for use in LTCC (low temperature cofired ceramics) technology, for integrating a passive electrical component in the volume of a multilayered ceramic body. Silver in particular can be used as an electroconductive material in this case.
