Abstract: In a central clock device (ZTE), ringing signals (rs) are formed in a ringing-tone generator and display signals (as) are formed by a direct-voltage source (GS). Using a central switching means (RU) controlled by a central processor device (ZPE), either the ringing signals (rs) or display signals (as) are transmitted to analog communication terminals via a ringing line (RL) and line access devices (LAE). In the line access devices (LAE), the ringing signals (rs) or display signals (as) are connected to the subscriber lines (ASL) with the aid of switching means (SE) which are controlled by a ringing/display procedure. For controlling the ringing/display procedure approximately without delay, random-access memory devices (DPR) with separated storage areas, into which information items are entered or, respectively, from which information items are read out by the input/output devices (EAE) and the central processor device (ZPE) are provided between the central processor device (ZPE) and input/output devices (EAE).

Abstract: A system for detecting the presence of known materials in a body or contain­er. The system incorporates a gamma or X-ray source for irradiating the body with gamma rays to produce X-ray fluorescence of materials contained therein. A direc­tionally discriminate X-ray detector is positioned to intercept X-rays emitted from the body and is adapted to pass only those X-rays having a predetermined wavelength and incident from a specific direction that are characteristic of a material of interest contained in the body. The detector includes a dislocation free single crystal having substantially parallel input and output surfaces. A second crystal aligned parallel to the first crystal may be disposed at a position offset from the first crystal to receive the X-rays transmitted by the first crystal in order to discriminate between materials fluorescing within the body. In a specific embodiment of the invention, the first de­tector comprises an elongated crystal which pass X-rays in accordance with the Bor­rmann effect. A plurality of the crystals are arranged in a linear array and the con­tainer is either scanned with the array or the container passed linearly past the array. The detected X-rays are measured in intensity and the data is processed by suitable data processor to generate a video image indicative of the presence and shape of the specific materials for which the system is adapted. In yet another specific embodi­ment of the invention, a plurality of such arrays can be arranged with the input sur­faces of the crystals disposed at different Bragg angles to simultaneously detect the presence of a selected group of materials.

Abstract: A line-type thermal transfer recording apparatus using a line thermal head (14) for a recording head (4b), wherein the line thermal head 814) is disposed in the vicinity of an end surface of the head (4b). Additionally, the thermal transfer recording material (9) is peeled off from the transfer paper (8) just after it is heated, and the relative speed between the thermal transfer recording material (9) and the thermal paper (8) is made different from one another, whereby the operation of destroying the cohesion of the thermal transfer ink (9a) is capable of being stably controlled. A mulitply transferable thermal tansfer recording material (9) yields a high printing quality, and a color thermal transfer recording paper brings about an improvement of the ink tone property without degrading the printing efficiency. Thus, when a color picture is printed using a multiple color surface sequence printing method, a clear picture with a wide color reproduction range can be printed.

Abstract: An optical system includes a wavelength-tunable laser which has an active layer (180) which includes periodically spaced thin sheets of dopant of alternate type, separated by intrinsic semiconductor material, so that band-gap has a saw-tooth shape in the direction perpendicular to the layer. Means (230,240) are provided for non-uniformly pumping the active layer. In use, part of the active layer is pumped to a degree which is less than that required to produce stimulated emission and part to a higher degree, so that laser action is obtained. The laser can be tuned by varying the low pumping level and/or the size of the low-pumping region and correspondingly varying the high pumping level.

Abstract: A marine seismic reflection prospecting system reduces coherent noise by applying a scale factor to the output of a pressure transducer and a particle velocity transducer positioned substantially adjacent one another in the water. The transducers can be positioned at a point in the water above the bottom and thereby eliminate downgoing components of reverberation, or they can be positioned on the bottom and thereby eliminate both upgoing and downgoing components of the reverberation. The scale factor, which derives from the acoustical impedance of the water or water-bottom material, can be determined both deterministically and statistically. The former involves measuring and comparing the responses of the pressure and velocity transducers to a pressure wave induced in the water. The latter involves comparing the magnitude of the pressure signal autocorrelation to the pressure and velocity signal crosscorrelation at selected lag values or, alternatively, comparing the magnitude of the pressure signal autocorrelation to the velocity signal autocorrelation at selected lag values.

Abstract: There is disclosed a color image processing method and apparatus therefor, in which the input image data are converted into a color coordinate system represented by luminocity and hue, for example L*a*b* space. The colors reproducible on the output device, for example a printer, are also converted into this coordinate system. An average value is calculated over plural pixels in the vicinity of an object pixel to be digitized, and plural average values are then obtained by including the object pixel selected at each of the reproducible colors. The input image signal is digitized to the closest one of the plural average signal. The digitization error generated at the digitization is distributed to the succeeding pixels with weighted ratios. This method achieves faithful color reproduction, matching the colors reproducible on the recording or display device.

Abstract: A superior thermal transfer film adhesive comprises the following composition: (a) at least one aliphatic epoxy resin; (b) a stoichiometric amount of at least one aliphatic polyamine curative; (c) an effective amount of a thixotropic agent, such as fumed silica; and (d) about 20 to 50 volume percent of at least one filler, such as alumina, based on the total of the epoxy resin and the curative. The aliphatic epoxy resin has aliphatic pendant chains of 6 to 20 carbon atoms in length. The curative comprises a long chain aliphatic or cycloaliphatic curing agent for the epoxy resin. Since aliphatic moieties, which are flexible, are used, the glass transition temperature of the resulting cured material is lower than epoxies and plasticizers employing rigid moieties. The adhesive of the invention is novel in attaining high volume resistivity (at least 10¹⁴ ohm-cm at 25°C), low temperature flexibility (-55°C), excellent adhesion for maximum thermal transfer, and ease of reworkability.
