Abstract: The mould exchanging apparatus, serving a plurality of plastic injection moulding machines, comprises an exchanging table (27), which serves as transporting carriage and can be moved in a linear guide (45) to a depot (44) for injection moulds as well as to the plastic injection moulding machines, aligned in parallel with the guide (45), in connecting position for the mould change. Two mould receiving places are arranged one behind the other on a rotatable carrier plate (27h) on the exchanging table (27). In the connecting positions, mould guides (G") of the receiving places, with the carrier plate (27b) turned if need be, form alternately with a mould guide of the mould clamping space of a plastic injection moulding machine and alternately with a mould guide of a depot receiving place (44a) transport tracks for the exchanging of an injection mould. It is achieved by such a design that the injection moulds of an entire group of plastic injection moulding machines can be exchanged fully automatically with the exchanging table (27), provided that the said machines are arranged in a space-saving manner with respect to the mould depot (44). This arrangement avoids running over the operator sides of the plastic injection moulding machines, and consequently the operator, following an upright transporter. <IMAGE>

Abstract: A system for removing excess material from a semicon­ductor wafer employs an excimer laser for ablative photocomposition. A wafer is positioned on an X-Y stage that is computer controlled to position the wafer at points where the laser may be focused to remove excess material whether over alignment marks or identi­fied contamination. The laser passes through a vacuum chamber ending in a nozzle structure which by generat­ing an inward laminar flow constrains any particulate contamination resulting from the ablative photodecomposition from spreading. This material is removed by the vacuum system.

Abstract: A DC to DC power converter (30ʹ) having reduced switching loss for operation at high frequencies. As disclosed, a buck, or forward, converter includes a first FET (31) as the switching device in series with an inductor (33) and a second FET (32) as the flywheel device. At the common node to which the two FET's and the inductor are connected, there is sufficient capacitance that the FET's may be turned off without appreciable voltage change across the FET's. The value of the inductor is chosen, with respect to the input and output voltages and frequencies of operation involved, to insure that the inductor current polarity reverses each cycle, raising the node voltage to the level of the input voltage, substantially eliminating turn-on losses of the first FET (31). Control circuitry is provided for regulation of the power converter to control the peak-to-peak current in the inductor and to insure that at least a selected minimum value of the inductor current is present for each cycle of operation of the converter.

Abstract: Die beschriebene Konferenzschaltung für ein digitales Nachrichtensystem ist für solche Nachrichtensysteme gedacht, bei denen sich die Analog-Digital- bzw. die Digital-Analog-Wandler mindestens zweier Teilnehmerendstellen in der Bandbreite ihrer verarbeitbaren Analogsignale oder in den Codes der Digitalsignale oder in der Schrittgeschwindigkeit der Digitalsignale unterscheiden können. Kein Konferenzteilnehmer muß sich an die Einrichtungen eines anderen Konferenzteilnehmers anpassen, weil die Konferenzschaltung für jeden Konferenzteilnehmer Transcoder (C11, C12; C21, C22; C31, C32) und entsprechende Transdecoder (D11, D12; D21, D22; D31, D32) unterschiedlicher Ausführung enthält. Der Aufwand ist nicht wesentlich höher als der, der bei der Realisierung des Vorschlages erforderlich ist, daß sich alle Konferenzteilnehmer vor der Konferenz auf die gleiche Bandbreite, den gleichen Code und die gleiche Schrittgeschwindigkeit zu einigen haben. Beim Aufbau einer Konferenzverbindung wird durch eine Steuerschaltung für jeden Konferenzteilnehmer der gerade für ihn benötigte Transcoder (C11.....C32) und der entsprechende Transdecoder (D11....D32) wirksam geschaltet. Dadurch wird erreicht, daß jeder Konferenzteilnehmer während der Konferenz Signale von den anderen Teilnehmern erhält, die die gleiche Qualtiät haben wie im Falle einer Verbindung zwischen nur zwei Teilnehmern.

Abstract: A keyboard entry system (10) is disclosed which comprises a keyboard (20) which includes a plurality of letter keys, one for each letter of a selected language. The entry system responds to conventional sequential activation of individual keys by providing output signals indicative of the respective individual letters associated with the activated keys to an application program (90) such as a word processor or printer control program. The keyboard entry system (10) also responds to chords of simultaneously activated multiple keys by using these chords to retrieve stored words from a dictionery (70). It is the stored words rather than the entered chords which are applied as inputs to the application program (90). This system allows an operator to use both conventional sequential key entry techniques and chorded entry techniques for rapid data entry. Chords are detected by comparing a stored constant with the elapsed time between a key release and the immediately preceding key depression of an overlapping key. The overlapping keys are characterised as a chord when the elapsed time is greater than the stored constant. A biofeedback mechanism alerts the operator of inadvertent chords.

Abstract: A dispersion transformer (14) is provided for limiting the data rate of an optical fiber transmission system. A transmission optical fiber (11), which connects a transmitter (Tx) and a receiver (Rx), may have a bandwidth much greater than that necessary to transmit a desired predetermined maximum data rate. The transmitted signal is connected to wavelength disperser means (15) which spatially separates the different wavelength components of the transmitted signal. Each wavelength component is then propagated with a different delay by optical fiber delay means (16-21). The wavelength component (λn) which propagates with the least delay through the transmission optical fiber (11) is subjected to the least induced delay in the optical fiber delay means (16-21) and that (λ₁) which propagates with the greatest delay through the transmission optical fiber (11) is subjected to the greatest induced delay in optical fiber delay means (16-21), the remaining components being subjected to intermediate delays. The delayed wavelength components are combined to form a series of broadened optical pulses (36).
