Abstract: An electronic circuit device is described which integrates novel components in its structure. Known circuit devices, because of the use of metal-oxide ceramics for insulating them with respect to the cooling surface, are limited in their packing density. Known, conventional wiring techniques further restrict the packing density. By using heat-conducting, electrically insulating and/or conductive pastes (14,30) and flexible printed-circuit boards (16,28) which are known per se, even in the field of high-power circuit devices, it is possible to increase the packing density of the components (22,32), to rationalise significantly the connection techniques (16,26,28) and to optimise contacting. Economical production, combined with a non-destructive partial dismantling option, while using pastes and films, permits further-reaching assembly of electronic circuit devices with a more extensive circuit capacity within one circuit unit. <IMAGE>

Abstract: It has been recognized that AlGaAs-containing planar waveguides (11, 12, 13) can be advantageously used in all-optical gates for wavelengths in the range 1.2 - 1.7 µm. In particular, such waveguides can produce in radiation pulses of center wavelength λ s  a phase shift of magnitude π or larger while, at the same time, causing attenuation of the pulse by less than 1/e, provided hc/λ s  < E g /2, where E g  is the bandgap associated with the Al x Ga 1-x As-containing waveguide. In preferred embodiments λ s  and/or x are selected such that [hc/(λ s -Δλ)] < E g /2, where Δλ is chosen such that 99% of the pulse energy is contained in the spectral region λ s  ± Δλ.

Abstract: The remaining capacity of a storage cell, particularly a valve regulated lead-acid cell, is determined by measuring its impedance at typically two or three relatively low frequencies f, e.g, frequencies in the approximate range of 0.01 to 1.0 Hz. In one scheme, the imaginary part Z˝ of the complex impedance Z(=Z′+ jZ˝) is plotted vs. f -1/2 , whereby the intercept Z           ˝       o              (at f  -1/2 =0) of the best-fitting straight line of the plot is a measure of the cell's remaining capacity. In another scheme, the slope (dZ˝/dZ′) of a plot of the imaginary part Z˝ vs. real part Z′ of the complex impedance Z, again as measured at such relatively low frequencies f, is a measure of the cell's remaining capacity.

Abstract: A video camera apparatus has a solid state imager for generating video signals and a black level balance adjusting circuit for automatically adjusting black levels of the video signals. The video camera apparatus comprises an incident light control device, an electronic shutter control circuit, a comparator and a processor. The incident light control device controls the amount of light incident to the solid state imager. The electronic shutter control circuit varies the mode of the solid state imager between at least a first mode and a second mode. The effective accumulating period of the solid state imager in the first mode is different from the corresponding period in the second mode. The comparator compares the voltage level of the video signal obtained in the first mode with that obtained in the second mode. The processor controls the electronic shutter control circuit and the comparator, and activates the black level balance adjusting circuit when the voltage levels of the video signals obtained in the first and the second modes are substantially the same.

Abstract: 1. The invention relates to a turntable for disc-shaped information carriers and the process for its production. 2.1 The object of the invention is to produce a turntable with little wobble and high centring accuracy. 2.2 According to the invention, this object is achieved by the turntable being formed by a perforated disc (LS) which has a shoulder (S) and is arranged on the inside, up to alongside the shoulder (S), embedded in a moulding (F) receiving a drive spindle. A centring piece (Z) is preferably integrated in the moulding (F) or configured as a separate part. Little wobble is achieved in particular by using a supporting surface (AF) of the turntable for the information carrier in the injection mould as a reference surface when the moulding (F) is being produced, thereby avoiding cumulative tolerances which adversely affect accuracy. 2.3 The application relates to turntables for equipment for playing back and/or recording disc-shaped information carriers, such as, for example CD, CD-ROMs, CD-videos or photo-CDs. <IMAGE>

Abstract: If a so-called through-passage leaf (2) and a fixed leaf (3) of a two-leaf door, with respectively rotatably mounted leaves, can be closed by means of a door closer (8) and (9) and the two leaves are provided with a leaf overhang, then the fixed leaf can only be opened if the through-passage leaf has previously been opened by a certain amount or to its full extent. Conversely, the fixed leaf can only be fully closed if the through-passage leaf is fixed in a partially open closure position which permits the overhang of the fixed leaf to be pivoted past the overhang of the through-passage leaf. The through-passage leaf is arrested in this partially open position with the aid of the closing-sequence control means, in that, via the opening movement of the fixed leaf, a piston (18) acting as stop element is brought into the movement path of a sliding roller (13) of the through-passage-leaf door-closer sliding arm (10). Said piston (18) is retained in the blocking position by means of a throughflow valve (56). The closing end movement of the fixed leaf (2) opens said valve (56) and a hydraulic block for the piston (18) is thus eliminated, with the result that the through-passage leaf can also close to the full extent. <IMAGE>

Abstract: A probabilistic neural network (PNN) comprises a layer L1 of input nodes, a layer L2 of exemplar nodes, a layer L3 of primary Parzen nodes, a layer L4 of sum nodes, and optionally a layer L5 of output nodes. Each exemplar node determines the degree of match between a respective exemplar vector and an input vector and feeds a respective primary Parzen node. The exemplar and primary Parzen nodes are grouped into design classes, with a sum node for each class which combines the outputs of the primary Parzen nodes for that class and feeds a corresponding output node. The network includes for each primary Parzen node (e.g. L3-2-3P) for the design classes a secondary Parzen node (L3-2-3S), the secondary Parzen nodes all feeding a null class sum node (L4-0). Each secondary Parzen node has a Parzen function with a lower peak amplitude and a broader spread than the corresponding primary Parzen node, and is fed from the exemplar node for that primary Parzen node. The secondary Parzen nodes in effect detect input vectors which are "sufficiently different" from the design classes - that is, null class vectors. The network is applicable to banknote recognition and authentication, the null class corresponding to counterfeit banknotes.
