Abstract: The switching element for self-routing multistage packet-­switching interconnection networks comprises: an input unit, composed of as many sections (IMA, IMB) as the element inputs are, each section comprising a FIFO memory (FIFA, FIFB) for packet buffering; a switch (SW) associated with a control unit (SCU) which, for each packet to be forwarded, sets up the connection requested for that packet between one input and one or more outputs of the element (ECP), on the ground of a routing tag associated with each packet and comprising a first and a second portion relative to normal routing and to broadcasting in the different stages of the network (RC), and solves possible routing conflicts between packets simultaneously arriving at different inputs; and an output unit, composed of as many sections (RU0, RU1) as the element outputs are and performing the whole of the functions necessary for the correct packet forwarding towards a destination. The control unit (SCU) of the switch (SW) is arranged to handle broad­casting of a packet independently of all other elements (ECP) in the same stage, so as to allow broadcasting also to a number of destina­tions different from a power of 2 (for an element with two inputs and two outputs) and cooperates with the memory (FIF) storing the packet to be broadcast in such a way that broadcasting does not give rise to internal blocking in the network (RC). Said contorl unit (SCU) moreover solves routing conflicts so as to set an upper bound to packet permanence time within the network.

Abstract: A method of manufacturing an insulated gate field effect transistor is described. The method comprises providing a gate layer (6) on an insulating layer (12) on one surface (4) of a semiconductor body (1) so that the gate layer (6) has a plurality of regularly arranged openings therein, introducing impurities into the semiconductor body so as to provide a plurality of source regions (2) of one conductivity type in the body, each source region (2) lying inside a respective opening of the gate layer (6) and being provided within a respective body region (14) of the opposite conductivity type, a portion of each body region (14) underlying a respective portion of the gate layer so as to provide a respective channel area extending between the respective source region (2) and a drain region (3) of the one conductivity type meeting another surface (5) of the semiconductor body opposite the one surface (4). Each source region (2) is shorted to the corresponding body region (14) by opening a contact window (15) in the insulating layer on the one surface so as to expose a surface of the source region (2), providing one or more masking regions (16) extending completely across the contact window in one direction so as to define an exposed area of the source region which is not covered by either the masking region(s) or the insulating layer (12), and has a periphery defined partly by the contact window and partly by the masking region(s), etching away the said area(s) of the source region (2) to expose an underlying area or areas of the body region (14), removing the masking region(s) and providing metallisation within the contact window (15) to short the exposed area(s) of the body region to the source region.

Abstract: In a character imaging system, a selected one of a plurality of different characters (letters, numerals, symbols etc.) arrayed as windows (22) in an otherwise opaque mask (20), is projected optically onto a selected location on a working surface (W). In this manner, laser light can be used to burn an impression into a workpiece, with successive characters spelling out words and sentences. Alternatively, the system can be used to project non-coherent light onto photographic film or onto a screen. The improvement in this type of system provided by the invention resides in the avoidance of a need to move the mask (20), or the working surface (W), or the final lens (Ll) that projects the light beam onto such surface. And yet the improved system nevertheless enables sequential selection of different characters in the mask, as necessary to build up words and sentences on the working surface. This improvement is achieved by scanning a light beam (l7) that is projected onto an imaging element, e.g. a concave mirror (M3) or a lens (L2), while synchronously scanning mirrors (M4, M5) that receive the imaged beam (l8, l9) in such a manner that the final beam (2l) is projected onto the workpiece (W) at a desired location regardless of which character-defining window in the mask (20) is traversed by the beam (l8, l9).

Abstract: An anhydrous cosmetic composition is provided comprising an emollient a thickening agent, a solubilizer, and a working ingredient for enhancing the appearance of or otherwise imparting beneficial effects to the skin. The preferred working ingredient is Vitamin A, or a blend of Vitamin A and derivatives thereof. The composition is exceptionally pleasing and cosmetically appealing when topically applied to the skin's surface, is surprisingly percutaneously absorbent, and maintains the working ingredient stable for extended periods. As a result, lower concentration levels of working ingredient (Vitamin A) are utilized then would otherwise be necessary to achieve improved skin appearance effects, thus avoiding irritation sometimes associated with Vitamin A containing cosmetic preparations.

Abstract: A power control circuit comprises a signal input (1), a controllable attenuator (2), an amplifier (3), an output (5), a power detector (4), a reference circuit, a comparator (6), an external control input (7), an error detector (8), and a controller (9). The comparator (6), error detector (8), and controller (9) are digital circuits realized by a microprocessor. The attenuator (2) is between the signal input (1) and the input (3A) to the amplifier (3) to regulate the amplifier's output (3b). The power detector (3) couples to the amplifier output to generate a measurement signal representing the power at the output. The reference circuit generates a reference signal representing a predetermined minimum output when the signal input is nonzero. The comparator (6) compares the measurement and reference signals and generates a decision signal (6b) indicating if the signal input is nonzero. The external control input (7) receives an external control signal. The error detector (8) is coupled to the power detector (4) and the external control input (7) and computes the difference between the external control signal and the measurement signal. When the measurement signal is at or above the minimum power, the controller (9) provides an integral of the computed difference to control the variable attenuator (2). When the measurement signal is below the minimum power, the controller (9) keeps the attenuator at a prior constant value.

Abstract: The scrambler has a controllable optical delay element whose delay can be controlled varying with time by means of a control arrangement in a periodic fashion such that for a given state of polarisation (SOP) of the light entering the polarisation scrambler, there occur at its output varying states of polarisation such that identical light intensities emerge on average over time at least approximately in each state of polarisation. An arrangement suitable for arbitrary input states of polarisation is produced when there is provided at least one further delay element (1, 2, 3), which follows the first one in the direction of light propagation, can be controlled by means of a control arrangement, and causes in the representation on the Poincaré sphere states of polarisation corresponding to another axis of rotation than that peculiar to the first delay element, and the delay elements (1, 2, 3) are triggered via their control arrangements with different frequencies (f1, f2, f3) or in an uncorrelated and aperiodic fashion.

Abstract: To determine the beginning and end point of a word signal within a speech signal from words spoken in isolation, three adjacent windows for the last stored digital values which have previously arrived are determined with each new digital value, the centre window of which is to contain the actual word signal. The length of this centre window is varied between a minimum and a maximum value for each digital value and from the energy contained therein, a threshold value is in each case subtracted which is determined from the two adjacent windows. In this manner, the method according to the invention in each case takes into consideration the complete speech signal instead of individual isolated regions, as a result of which the end point can be determined more reliably. …<IMAGE>…
