Abstract: The device serves for the making of ice grains for grain-blasting devices. A carrier has a cooling surface, on which liquid particles harden to form ice. The ice is then separated. The aim is to manufacture the ice grains separated from one another respectively with high dimensional accuracy. To this end, a drop former is used, which is arranged above the cooling surface. The ice-separating device has a stripping edge which is parallel to the cooling surface. It rests on the cooling surface. <IMAGE>

Abstract: A single flash discharge tube system is pro­vided that is capable of emitting artificial light of a controlled and variable spectral output to compensate for photographic film color variations and/or extremes in scene color temperature. The flash tube contains a mixture of two or more gasses with each gas in the tube having a different ionization potential.

Abstract: In an image forming apparatus for forming an ordinary copy or a tonality image for an original image for a printing master, original image data is divided into a predetermined area, and pixel density within the area is subjected to a density conversion in accordance with screen half-toning information which will increase density information toward the approximate center of these pixels, by way of example. The original image data or the density-converted image data is converted into a binary-coded signal conforming to the density, and an output image is formed in accordance therewith. Preferably, a specific mark is supperimposed on the output image.

Abstract: Cryptographic PIN processing is achieved in an improved manner by associating control vectors with the PIN generating (verification) keys and PIN encrypting keys which provide authorisation for the uses of the keys intended by the originator of the keys. The originator may be the local cryptograhic facility (CF) and a utility program under the control of a security administrator, or the originator may be another network node which uses compatible key management methods to distribute the keys. Among the uses specified by the control vector are limitations on the authority to use the associated key with certain PIN processing instructions, such as PIN generation, verification, translation and PIN block creation. Furthermore, the control vector may limit the authority of certain instructions to process clear PIN inputs (such as in PIN verification). The control vector may contain information identifying and, possibly restricting, PIN processing to a particular PIN format or particular processing algorithm.

Abstract: For producing an undersurface for skis, a material is produced in band form from a polyethylene having an average molecular weight (weight average) in the range between 5.10<5> and 8.10<6> by a ram extrusion process, a relief-like surface structure being formed on at least one of the surface sides of the said material before it cools, the said structure being intended to improve the sliding properties on the snow on the running side and improve the bonding properties of the undersurface on the bonding side. This surface structure, the roughness height Ra of which lies in the range of just a few  mu m, is impressed in the material to create fine surface grooves or ribs by corresponding shaping of the contour of the die orifice at the extruder output or, for example, in a band press by the structure of a fabric running along with it. This undersurface is preferably produced in ski production in the form of an undersurface prefabricate on which the undersides of the steel edges of the ski are flush with the upper edges of the ribs of the said undersurface. <IMAGE>

Abstract: A three-phase motor (10) is operated by a controller (20) having sets of thyristors (16, 17, 18) which when triggered switch electricity from each phase of a supply to the motor. The controller (20) measures the interval φ between when the voltage and the current for one phase to the motor make zero crossings and measures the interval γ that the thyristor is non-conductive during each half-cycle of the voltage for the one phase. A control angle ϑ is calculated according to the equation ϑ = φ + Kγ , where K is a positive number, the control angle ϑ is compared to a reference value to derive an error value. The times at which the thyristors are triggered is controlled in response to the error value. To start the motor, the reference value is gradually decreased to trigger the thyristors progressively earlier during each half cycle of the supply voltage. To stop the motor, the reference value is gradually increased to trigger the thyristors progressively later during each half cycle of the supply voltage.

Abstract: A method for fabricating integrated circuits is used to improve contacts between polycrystalline interconnect and underlying polycrystalline or monocrystalline silicon regions. After contact openings are formed, a layer of titanium (48) is deposited over the integrated circuit. The titanium is reacted in nitrogen to form a silicide layer only in the openings. Titanium nitride and unreacted titanium are then removed, and a layer of polycrystalline silicon (56) deposited and patterned. The silicide (50, 51, 52) layer between the polycrystalline interconnect and the underlying silicon ensures that a high quality contact is formed.

Abstract: A tensioner (10) for an engine-driven chain applies a decreasing tensioning force to the chain as engine speed increases to suppress howling. The tensioning force is applied by a spring. The decrease in force is achieved by an expansible chamber (17) in fluid communication (24) with the engine lubrication system. As engine speed increases, lubricant pressure increases, causing the expansible chamber (17) to apply a force to the tensioner plunger (13) which opposes the force tending to apply tension to the chain. In two embodiments described, a ratchet (19) with backlash is used to prevent excessive slackening of the chain following sudden increases in chain tension. The backlash allows the lubricant pressure in the expansible chamber (17) to decrease the force applied by the tensioner to the chain. In a third embodiment, a floating tensioner assembly, including a plunger, a floating housing, a spring and a ratchet, is urged as a whole against a second spring by hydraulic pressure applying a force to the plunger and an opposite force to a fixed housing.

Abstract: A nonlinear optical device structure (20) is formed by a compound semiconductor having a graded chemical composition such that the average drift velocity of electrons is in the same direction as, but of greater magnitude than, that of holes. In this way, when a pump optical beam (control beam) (135) is flashed (as by a picosecond pulse) upon the structure, electron-hole pairs are created with a resulting temporary spatial separation between the holes and the electron--whereby an electric dipole moment is temporarily induced in the structure. In turn, this dipole moment temporarily modifies either the birefringence or absorption property, or both, with respect to a controlled beam (125)--whereby the polarization, phase, or intensity, of the controlled beam (125) can be modified by the control beam (135). After the electrons and holes drift to positions which extinguish the dipole the structure is ready for a repeat performance.

Abstract: A method is proposed for determining the distance from an investigating device (10) to the surface (12) of a medium capable of supporting wave propagation. According to the method, a propagatory wave is generated at a given location (T₁,T₂) along the surface of said medium and spaced laterally therefrom. The propagatory wave is caused to enter the medium and to propagate in the medium. The phase of the propagating signal is detected at a pair of locations (R₁, R₂) respectively spaced longitudinally along the surface of the medium by different distances from the transmitting location. An indication of the lateral spacing between the detecting means and the medium is determined in response to the phase information detected at the pair of locations.

Abstract: According to this invention, a sharpness emphasis is carried out by multiplying a sharpness emphasis signal of an original image by a function of a look-up table which is accessed based on an output from an edge detecting filter performing detections in accordance with only the edge portions of the original image. Since the edge detecting filter for detecting edges of the image is equipped in order to emphasize the sharpness only in the edge portions of the image, it is possible to prevent the image grains from being sharpness-emphasized. In addition, although the edge detecting filter may have a same size of a mask with that of the unsharpness mask, it is possible, if required, to modify freely both sizes of the masks, in order to perform a proper process in accordance with each image variation.
