Title: Bioreaktor
Inventor: RIETSCHEL WOLFGANG
IPC: C12M1/12
Filed: 1988-05-03
Abstract: Bioreaktoren müssen mit Dampf sterilisiert werden. Bei der Sterilisierung in situ, also mit im Gefäß enthaltener Flüssigkeit, besteht die Gefahr, daß durch das in die Flüssigkeit eintauchende Rohr Flüssigkeit vom Dampf ausgetrieben wird. Nach der Erfindung ist das in die Flüssigkeit (15) eintauchende Rohr (14) über ein Ventil (20) und über ein 3/2-Wegeventil (22) an die Kondensatleitung (D) und an eine Arbeitsleitung (A) anschließbar. Beim Sterilisieren strömt Dampf durch das Ventil (20) und das 3/2-Wegeventil (22). Dieses Ventil (20) befindet sich in einer Stellung, in der sowohl in den Kopfraum (47) des Gefäßes (11) als auch in das Rohr (14) öffnet. Dadurch wird der gesamte Innenraum des Gefäßes (11) mit gleichem Druck beaufschlagt. In der Arbeitsstellung verbindet das Ventil (20) die Leitung (21) ausschließlich mit dem Innern des Rohres (14), wobei die Verbindung zum Kopfraum (47) gesperrt ist. Alle an die Leitung (21) angeschlossenen Komponenten werden durch den Dampf sterilisiert.

Abstract: A method for forming a BICMOS device having MOS devices and bipolar devices formed during the same process includes the step of first forming bipolar (22) and MOS (24) regions and then forming gate electrodes (50) in the MOS regions and poly emitters (56) in the bipolar regions. The gate electrodes (50) and poly emitters (56) have a layer of refractory metal (52, 58) formed on the upper surface thereof and covered by a protective cap (54, 60). The extrinsic bases (120, 122) formed on either side of the emitter electrode (56) and the source/drain regions (116, 118) are formed on either side of the gate electrode (50) by forming a layer of silicide (78, 80, 84, 86) and implanting the layer of silicide (78, 80, 84, 86) with p-type impurities which are subsequently driven downward. The protective cap (60) prevents the p-type impurities from being introduced into the poly emitter (56).

Abstract: According to Figure 3, a number of squarewave signals (I1...I20) obtained by subdivision from sampling signals (A1,A2) are supplied to a memory (S) which exhibits a number of bistable flip flops corresponding to the number of squarewave signals, which are selected by at least one periodic auxiliary signal (CLK). At the output of the memory (S), a logic (I) is located which examines the states of the flip flops for validity. The output signal states of the flip flops are converted into a binary code (NB) by means of a code converter (C). The count of a subsequent binary counter (Z) is influenced by the aforementioned periodic auxiliary signal (CLK). The count is supplied in the form of a further binary code (NZ) to a comparator (A) which compares the output code of the code converter (C) with the coded count (NZ) and in the case of deviations supplies the binary counter (Z) with control signals which, in interaction with the auxiliary signal (CLK), correct the count with fixed clock rate to the binary code (NB) of the code converter (C). The output signals of the binary counter (Z) are converted in a decoding circuit (OS) into a two-bit Gray code from which the output signals (01 and 02) for an evaluating circuit (R) are formed.

Abstract: In light display devices in which a display recessed in a frosted-glass pane is illuminated by an incandescent bulb arranged behind it or in which a light-emitting diode arrangement is arranged as display, the contrast between the light display and the surrounding area is reduced with incident sunlight to such an extent that the display is scarcely visible. So that, in traffic lights operated on demand, the display "wait", which lights up when it is operated, can also be seen clearly with incident sunlight, the light display device contains a transflective liquid-crystal display unit at the rear side of which facing away from the viewing window of the light display device, a light-emitting diode arrangement is provided as light source which is embedded in a reflector. In this arrangement, the liquid-crystal display appears as a shadow in an illuminated field of light, the contrast being even enhanced by incident sunlight. <IMAGE>

Abstract: A Customer Activation System, including a method and apparatus, for expeditiously providing a cellular mobile radiotelephone (CMR) customer access to CMR service. The system includes a regional processor programmed to:
     (a) accept information identifying the CMR customer;   (b) obtain a credit check of the CMR customer;   (c) assign a telephone number to the CMR customer; and   (d) insert and activate the telephone number in a cellular switch.   
     Specifically, once a selling agent has been permitted to log on to the System, the agent enters, through a data entry device coupled to the regional processor, the customer's social security number. The regional processor responds with a voice prompt that provides expanded information derived from the social security number. If the expanded information is accurate, the processor obtains a credit check by, for example, commissioning a credit service bureau. If the credit check results in approval, the agent then enters, via the data entry device, number data corresponding to the NPA/NNX of the CMR system to which the customer desires to subscribe. The regional processor allocates a 4-digit suffix to the NPA/NNX so   as to formulate the customer's CMR telephone number or MID. The processor then inserts and activates the MID in an associated cellular switch. In addition, should the need arise during the customer activation process, the processor has the capability of connecting the agent to a customer service representative. Finally, the System generates a billing record for entry on a billing processor and, after the billing record is properly generated and inserted, generates a "Welcome" letter to confirm the customer's personal data and selection of service options.

Abstract: A digital wipe generator has a digital waveform generator to generate X and Y digital waveforms from a composite sync signal. A digital wipe solid generator processes the X and Y digital waveforms to produce a digital wipe solid waveform. The wipe solid generator has a circle generator using a square root function which preshifts the sum of the squares prior to access to a look-up table, and then post shifts the output of the look-up table by one-half the amount of the preshift to produce a desired curve pattern for the digital wipe solid waveform. The digital wipe solid waveform is input to mixer circuits where it is processed to produce an anti-aliased key signal for mixing external video signals, the anti-aliasing being based upon an interpolation/decimation scheme using fractional bits of the digital wipe solid waveform. The output of the mixer circuits is a desired wipe transition.

Abstract: A system for automated control of the deposition of a film on a substrate is disclosed. The system includes a material deposition apparatus for deposition of a desired material or materials on a substrate located within a deposition reactor. A witness wafer mounted on a turn­table in the deposition reactor provides selective expo­sure of a small area of the witness wafer surface through an opening in a mask. An ellipsometric measuring device is employed to measure the thickness of the film deposited on the exposed area of the wafer surface in real time without removal of the wafer from the reactor. A central controller monitors the thickness of the film as it is being deposited, and automatically controls the deposition control variables to compensate for errors in the thick­ness of successive layers and provide an optical structure having the desire characteristics.
