Abstract: In humid atmospheres (e.g., 55% relative humidity or above) solutions of 2,2-bis(3,4-dicarboxyphenyl)hexa­fluoropropane dianhydride/2,2-bis[4-(aminophenoxy)phenyl]­hexafluoropropane polyamic acid polymers or polyimides tend to be unstable in the sense that during spin coating operations undesirable precipitate formation may occur on the rotating surface of a semiconductor wafer. The result is the formation of unacceptable coatings due to their irregularity and lack of uniformity. Described are solu­tions of these polyamic acid polymers or polyimides in a solvent containing at least 40% by weight of one or more liquid aromatic hydrocarbons having a boiling point of at least about 110°C and at least 5% by weight of one or more dipolar aprotic solvents having a boiling point of at least about 150°C, such that the solution (a) contains on a weight basis from 5% to 40% of the polyamic acid or from 5% to 50% of the polyimide and (b) does not undergo precip­itate formation during spin coating in an atmosphere of up to at least about 55% relative humidity.

Abstract: In a multiprocessor system (FIG. 1), the processors (10-12) are interconnected by a non-blocking communication medium such as a crossbar switch (19). Each processor is connected to a dedicated port circuit (18) at the switch by an optical link (16). Each port circuit is conected to the crossbar switch by an electrical link (20). The port circuits are interconnected by a contention medium (14). A port circuit sends an access request by its connected processor to the destination processor over the contention medium. Circuitry (205) at each port circuit receives requests, for access to the connected processor, prioritizes conflicting requests, and grants them sequentially. The circuitry interleaves grants of access to the connected processor with grants of outgoing access requests made by the connected processor. The circuitry grants an access request by causing the crossbar switch to establish the corresponding connection.

Abstract: A method is disclosed for displaying and confirming the status of a plurality of deferred requests for processing by a system made by an end user of that system. Each request made by an end user is monitored and an indication of each deferred request is stored in a deferred status request list which acts as an electronic "out basket." The deferred status request list includes an indication of the date and time of each request as well as an indication of the type of request. An indication of the status of each deferred request can be periodically generated and stored within the deferred status request list so that the end user may determine whether or not the request is pending, running, or completed. The end user may also selectively view the deferred status request list and alter the status of a selected request by deleting it, placing it in a hold status, or viewing the results of that request.

Abstract: Production of a glazing, ready to be installed, and intended to be bonded to the frame of a vehicle body void. 
<??>According to the invention there are deposited, on the pane of glass (1), or on an opaque lining (10) in the form of a frame adhering to the pane (1), two partial beads of adhesive (18), simultaneously or one immediately behind the other. The adhesive mass forming the first profiled bead (18) is selected or treated in such a way that this partial bead sets in a comparatively short time. The adhesive mass forming the other partial profiled bead (15) is selected or treated in such a way that this bead (15) remains plastically deformable and adhering for long enough to be used directly in bonding the glazing to the void during its mounting. The bead of adhesive (18), which sets in a short time, can be used if required to attach parts of the structural frame, for example a tearing thread (21), and advantageously comprises a shaped sealing lip (20).

Abstract: A method is disclosed for dynamically redefining a shell structure which includes embedded formatting, processing or resource information. The shell structure includes end user requirements necessary to process con­structs within a data stream which are accessed by means of embedded tags within the data stream. Data stream clutter is reduced and end user formatting is rendered more flexible by embedding tags in the data stream to a point in one or more shells accessible by the end user's work station; however, it is often desirable to modify a particular shell for a specific application without perma­nently altering the shell. A formatting shell fragment is created in accordance with the present invention which includes a reference to a complete shell and a temporary modification to be applied to that shell. In a preferred embodiment of the present invention multiple formatting shell fragments may be concatenated with other formatting shell fragments and a complete shell. In this manner, a data stream may be processed by utilizing an existing shell structure which has been temporarily redefined for that purpose.

Abstract: A frequency response stabilized amplitude modulation circuit includes a variable gain ampli­tude modulator (20) producing an output signal (V RF,M,P ) of which the amplitude is proportional to the product of the amplitudes of a carrier signal (V RF,I ), a modulating signal (V M ) and a gain control signal (V P . An envelope detector (14) generates a signal (V D  of which the amplitude depends on the modulation envelope of the output signal. A first difference amplifier (16) produces the modulating signal input for the amplitude modulator in proportion to the difference in amplitude between the envelope detection signal and an audio input signal (V C ). The modulating signal incorporates negative feedback to ensure that the envelope amplitude of the modulated output signal tracks the audio input. A second difference amplifier (18) provides the gain control signal input for the amplitude modulator in accordance with the difference in amplitude between the modulating signal, scaled by a constant factor, and the envelope detection signal. The second difference amplifier minimizes influence of carrier signal frequency on modulation frequency response by accordingly adjusting the gain of the modulation circuit.
