Abstract: The invention proposes a mechanical or hydraulic press with a drawing device for drawing work or a drawing station for a multiple stage press, the workpiece (6) of which is clamped by means of a platen (7). In order to damp the impact which occurs when the top tool (8) strikes the platen (7) and, especially to damp the impact noise, the movement of the press ram (9) is transmitted to at least one hydraulic cylinder (33), the hydraulic medium of which acts via a control device or under positive control on a further pressure cylinder (13) and especially a damping cylinder (13) which is connected to the die cushion and hence to the platen (7). <IMAGE>

Abstract: In an interpolated signal producing circuit, amplitudes of a plurality of proximate pixel signals derived by delay circuits (202, 203) are compared in logical operating circuits (205 to 209) and the order of magnitudes of such pixel signals is determined, whereupon an interpolated signal is derived (210) which is intermediate between the largest and smallest amplitudes, for example, next to the largest or smallest amplitudes or an average thereof. The interpolated signal thus derived may be employed for sub-sampling, that is, doubling the number of pixels in each horizontal scanning line of a displayed video picture, for doubling the horizontal scanning lines in a field, or in compensating for drop-out.

Abstract: A method and apparatus (Fig. 3 and 4) for correcting a signal representing the integral of an input signal ACC. (Fig. 3) to eliminate the effects of errors in the input signal comprises deriving from one or more signals which bear functional relationship with the errors samples 15′ at 16, subjecting the samples to a correction algorithmic process at 18, integrating the process results at 19 and therewith correcting the input signal integral at 21. This differs from known arrangements, that demand a high sampling rate (at intervals 16) in accordance with the Nyquist sampling theorem and result in a large amount of sample data to be processed, by processing fewer samples 15′ taken at below the Nyquist rate at random or pseudorandom intervals or random ones of the intervals 16. Relatively few samples 15′ processed and integrated provide an acceptable quantitive estimate of the error in the integrated input signal. Preferably, and particularly to assist in low demands on computerised sample processing, the samples are spaced throughout the integration period by defining window intervals 25 and taking one or more samples 15′ randomly in each window interval.

Abstract: A thin film electroluminescent edge emitter structure [Fig. 1 (10)] includes a common electrode layer (12) and control electrodes (20) disposed above the common electrode layer. At least one dielectric layer (14 or 16) is disposed between the common electrode layer (12) and control electrodes, and a phosphor layer (18) is inter­posed between the one dielectric layer and common elec­trode layer. The common electrode layer, one dielectric layer and the phosphor layer define the light-emitting pixels (24) of the emitter structure. Each pixel has a light-emitting face (24A) formed thereon and is operable upon application of electrical excitation to cause the radiation of light energy within its phosphor layer at least in a direction towards the pixel light-emitting face. An optical lens system [Fig. 3 (36), Figs. 4-7] associated with the pixels includes a preselected contour (34A) shaped on the light-emitting face of each pixel to define an optical lens integral therewith to project the light energy passed therethrough in a preselected direc­tion and form a beam of light energy having a preselected beam pattern. A multi-color light emission system [Fig. 10 (46) ] employed by the pixels includes a plurality of phosphor zones (48 (1), (2), (3)) composing the phosphor layer and capable of projecting different light energy through the light-emitting faces (48A) of the pixels. Also, separate edge emitter structures projecting   different colors of light can be utilized in a electro­photographic printer.

Abstract: An output of a magnetron (1) operating in the TM₀₁ has a ceramic output window (10) which is planar. As ceramic material may have a higher dielectric constant than glass a longer output probe (8) can be used which, combined with the fact that the window (10) is planar, gives good mode purity reducing heating and arcing in the window. Ceramic also has a higher melting point than glass which means that cooling of the window (10) is less critical.

Abstract: In an electrochemical secondary cell containing anhydrous electrolyte whose charging/discharging mechanism is based on reversible intercalation of active Li<+> ions by an electrode material having an open skeleton structure, the positive electrode is essentially a lithium-manganese spinel of the LiqMxMnyOz type which, provided 0 < x < 0.6 and 1.4 < y < 2.0, may contain up to 30% of other metals M, for example Co, in addition to Mn, while the negative electrode is based on a carbon product produced pyrolitically from organic compounds as host substance for the Li<+> ions. Limiting the Li concentration in the spinel lattice to a range in which the numerical values of the sliding parameter q are between 0 and 1.3 results in a low-lithium manganese spinel as positive electrode material. This spinel is responsible for the fact that, during discharge, the secondary cell delivers most of its capacity at a cell voltage of > 3 volts and that it also has a high cycle stability.

The plurality of sub-fields have lengths of time proportional to weights of the corresponding bits. The luminous elements show different levels of brightness in sub-fields corresponding to bits, having values of "1" or "0", of a multiple-bit code. For each luminous element, the time interval (Tm) from a light emission start time in a sub-field where the first light emission occurs in a time corresponding to a field till a light emission start time in a sub-field where the last light emission occurs in a time corresponding to a field is made shorter than the critical fusion period of the perception characteristic of human eyes.

Abstract: A magnetic recording medium (13) having a triple layered structure including a substrate (8), a first layer or a soft magnetic thin film (9) of high permeability piled on the substrate (8), a second layer or a vertical magnetization film (10) piled on the first layer (9), a third layer or a soft magnetic film (11) of high permeability piled on the second layer (10). A magnetic recording apparatus (FIG.1) alternately switches the magnetization orientations of the second layer or the vertical magnetization film (10) at a recording location where a latent image is to be formed. The first and third layer or the soft magnetic thin films (9 and 11) can improve recording efficiency. The field produced by the second layer or the vertical magnetization film (10) causes the third layer or the soft magnetic thin film (11) to be magnetized along the surface (20) of the magnetic recording medium (13), and this results in the concentration of the flux owing to switching of the magnetization directions. This enables high density recording and improves recording sensitivity and reproducing sensitivity.
