  • Patent number: 4858124
    Abstract: Methods for enhancement of data obtained from scanning objects such as body tissue with ultrasonic wideband pulses to detect characteristics of the tissue and to identify the tissue. The methods include performing spectral analysis on selected time portions of signals obtained from ultrasonic scanning to derive spectral data which is representative of the received signal characteristics for spatial samples of a particular region of interest in the body. The characteristic values are selected to correlate with significant characteristics of the material. A display of the selected body region is generated, with the display characteristic for each of the spatial samples being selected in accordance with the derived spectral characteristic values. Examples of the spectral characteristic values include spectral amplitude, spectral slope, and spectral amplitude uncertainty.

  • Patent number: 4857940
    Abstract: A molded article containing an electrical element buried therein has at least two leads, and portions of the leads are left exposed. The article is improved in that all of the leads are left confined within the confines of the article, the exposed portions of the leads being disposed within at least one aperture through the article.Also a molding process for making the article useful as a catcher plate for an ink jet printer. Broadly, the process comprises the steps of placing the portions of the leads to be exposed, each in a groove in a post that is part of the mold, and closing the mold cavity with a closure plate containing an elastomeric material aligned with the post and leads, such elastomeric material having a coefficient of thermal expansion that is greater than that of the material used to make the mold.

  • Patent number: 4857880
    Abstract: Electrical devices containing PTC conductive polymers which have been cross-linked in two steps, preferably by radiation. The conductive polymer is heat-treated above the temperature at which it begins to melt between the two cross-linking steps, and/or the cross-linking steps are such that a center section of the conductive polymer, intermediate the electrodes, is substantially more cross-linked than the conductive polymer adjacent the electrodes. The process is particularly useful for the preparation of circuit protection devices which are subject to high voltage faults.

  • Patent number: 4855758
    Abstract: A thermal transfer recording apparatus adapted to record an image on a recording medium by transferring a heat-transferable ink from a transfer medium to the recording medium. The apparatus has a transfer medium having on one surface a layer of a heat-transferable electroconductive ink formed on a base sheet, a recording head for heating the transfer medium in accordance with an image signal, and an electrode disposed in physical contact with the ink surface of the transfer medium so as to form a path through which electric current is allowed to flow between said electrode and said transfer medium. Therefore, the apparatus prevents any path for electricity from being formed between the transfer medium and the recording head.

  • Patent number: 4855757
    Abstract: A thermal printhead for dissipating accumulated static electric charge. An electrically conducting outer layer is deposited over the surface of a thermal printhead that receives static charge from the passing print media or ribbon media. The layer, which can be a 100-angstrom-thick layer of chromium, is formed over a glass overglaze. If the surface overglaze is passivated, a 10-angstrom-thick activating primer layer is formed on the glass overglaze before the chromium layer is deposited. The conductive outer layer is connected to electrical ground to dissipate the static electric charge as it is generated.

  • Patent number: 4855761
    Abstract: A recording apparatus for recording information with a light beam, having a beam deflector for deflecting the light beam in the direction of main scan by a sine wave oscillation. The deflection angle of the light beam from the beam deflector is amplified in the direction of the main scan by means of an afocal anamorphic optical system. This arrangement makes it possible to effect the main scan with the light beam which has been deflected by the light deflector while the angle of oscillation of the light deflector is within a smallest region.
