Abstract: The invention relates to a process for the preparation of high-molecular-weight, optionally branched polyarylene sulfides (PASs), preferably polyphenylene sulfide (PPS), having a reduced content of extractable oligomeric and monomeric constituents. They are prepared in a polar organic solvent by reacting alkali metal sulfides and/or alkali metal hydrogen sulfides with dihaloaromatic compounds, the alkali metal sulfides and/or alkali metal hydrogen sulfides being fed to the reaction mixture in water-containing melt-liquid form, optionally mixed with the organic solvent, via a nozzle.

Abstract: A digital copier is provided with mechanism (40) for reading images of both sides of an original, and mechanism (32, 34, 35, 36) for storing image data read by the reading mechanism in an area of an image memory (33) in order, and when a predetermined signal is applied thereto, for storing image data in the next area by one area. The predetermined signal may be generated when a skip key is depressed. Therefore, since it is not necessary to read images which needs not to be recorded, the appearance of the recorded images on a record sheet is improved and the processing time is shortened. The digital copier may be also provided with mechanism (32, 34, 36) for storing blank data in remaining areas in the image memory when a predetermined signal is applied thereto. The predetermined signal may be generated when an end key is depressed.

Abstract: A method is provided for operating a networked computer system including a plurality of computers, some of which exhibit different data formats and some of which exhibit identical data formats. Prior to sending a message from a sending computer to a receiving computer on the network, the sending computer sends its data format requirements to the receiving computer. When the receiving computer receives the message from the sending computer, the message is converted from the data format of the sending computer to the data format of the receiving computer if the data format requirements of the sending and receiving computers are found to be different. The converted message thus generated is then passed to application software. If however, the data format requirements of the sending and receiving computers are found to be the same, then the received message is passed to application software without conversion.

Abstract: 5 n7 This invention relates to a method of establishing connections over a public switched telephone network to a customer whose telephone number is in a block associated, for routing purposes, with a first telephone switching system, but who is actually served by a second telephone switching system. The facility for carrying out this method is desirable in order to serve customers who need the advanced functions of a digital switching system, who are currently served by an analog switching system, and do not wish to have their telephone number changed when they switch to being served by the digital switching system. In accordance with the invention, a common channel signaling initial address message is sent to the first system. The first system translates the telephone number of that initial address message and finds that the customer for that telephone number is now served by a second switch. The first switch then sends a release message containing the identification of the second switch back to the source of the initial address message. The source of the first initial address message then sends a second initial address message to the identified second switch and the call connection can now be established to the customer served by the second switch. During the time the customer is being moved from the first switch to the second switch, one of the two returns a "temporarily out of service" type of announcement.

Abstract: A data tape cartridge is formed on a baseplate (30) of polymeric material which supports mounting pins and tape guides thereon for supporting tape components in rigid and dimensionally-stable manner using integrally formed bosses (43) to support the mounting pins (45) and guides (46). Additional stability against flexure is achieved using a matrix pattern of integrally-formed webs or ribs and sidewalls (34,36) in the baseplate and by attaching a top plate substantially about the entire perimeter of the sidewalls. Lateral forces exerted against rotatable components on the mounting pins are transferred to the baseplate (30) and top plate (12) by the mounting pins (45) that are supported in both plates. A midguide support (50) is integrally formed in the baseplate to support a guide pin (55) at critical location adjacent the location along the tape path in the cartridge at which a tape transducer interacts with tape. Methods of assembly include inserting mounting pins and tape guides into the baseplate while the material of the baseplate about the mounting pins is plasticized, and also include assembling the components of the cartridge in upside-down orientation for transfer to aligned pins and guides in the baseplate.

Abstract: A system for securing a plurality of tape pancakes (12) includes a compressible core support (24) on which the pancakes (12) can be mounted. An interior rod (26) having a head (28) fits and is received within the core support (24). A nub (34) on the inside surface (36) of the core support (24) engages a groove (38) on the outside surface (40) of the interior rod (26) to provide a threaded engagement between the interior rod (26) and the core support (24). Rotation of the interior rod (26) within the core support (24) after the head (28) contacts the end of the core support (24) provides an axial compression load onto the core support (24) to hold together the pancakes (12). This axial compression also expands the baffles which contact and tighten against the inside of the tape pancake cores and provide a radial force to secure the pancakes (12) in place.

Abstract: A row and column based storage device stores data at multiple density levels. The bulk of the stored data is record data, and is stored at higher density levels to minimize the storage area required. The control information and system parameters are stored at lower density levels for maximum reliability. Lost or damaged record data may be recovered through error correction parity data. However, lost control information or system parameters results in catastrophic failure of the storage device.

Abstract: The method of this invention allows use of a smaller wordline voltage Vp1 during programming. In addition, the method results in a relatively narrow distribution of threshold voltages Vt when used to flash program an array of memory cells (10). The method of this invention increases compaction gate-current efficiency by reverse biasing the source (11)/substrate (23) junction of the cell being programmed. The reverse biasing is accomplished, for example, by applying a bias voltage to the source (11) or by placing a diode (27), a resistor (29) or other impedance in series with the source (11). The reverse biasing limits the source current (Is) of cell being programmed and of the entire array during flash-programming compaction.

Abstract: An acoustic production system having multiple signal sources (20,22) and a power amplifier (28) driving an acoustic transducer (32) such as a loudspeaker includes an arbitrator in a power limiter circuit to selectively limit the input level of one of the sources to the power amp (28) in response to an overdrive signal from the amplifier. The input level to the power amplifier (28) is automatically reduced in response to the overdrive signal until a predetermined level of limiting has been attained. Once the predetermined level of limiting is reached, the arbitrator (62) outputs a second overdrive signal to prompt additional limiting of the power amplifier output. Preferably, the arbitrator (62) is included in an interior active noise cancellation module (22) combined with an audio entertainment system for a passenger compartment of a motor vehicle. The audio system (12) also preferably separates the audio reproduction into high frequency and low frequency branches, whereby the arbitrator (62) acts upon the signals output in the frequency ranges of active noise cancellation and the bass output of the audio entertainment system that are most likely to overdrive an amplifier.
