Abstract: Circuitry formed at a surface of a substrate includes first and second lines (180,182) in first and second layers of the circuitry. The first line (180) includes semiconductor material and extends between first and second connecting points (190,192) at which it connects electrically to other components. The second line (182) is connected (188) to receive a gate signal, and crosses the first line (180) in two or more channel regions (184,186). The first line (180) includes a channel in each channel region, and the channels are in series. The second line (182) conducts the gate signal to all of the channel regions. The first line (180) includes charge carrier sources and destinations positioned so that conductivity of the first line between the first and second connecting points is controlled by the gate signal. The first layer can be polysilicon, and the second layer can be polysilicon or metal. The first line can be undoped in the channel regions (184,186) but heavily doped in other areas. Each of the first and second lines can include an angle of approximately 90° between two of the channel regions, forming a Crossed-L configuration. In an active matrix display or other array with M scan lines and N data lines, the first line (180) can be connected to the  n th data line (172) and the second line (182) can receive the gate signal from the  m th scan line (170).

IPC: G10L25/93

Abstract: A speech decoder includes a first portion comprising an adaptive codebook and a second portion comprising a fixed codebook. The decoder generates a speech excitation signal selectively based on output signals from said first and second portions when said decoder fails to receive reliably at least a portion of a current frame of compressed speech information. The decoder does this by classifying the speech signal to be generated as periodic or non-periodic and then generating an excitation signal based on this classification. If the speech signal is classified as periodic, the excitation signal is generated based on the output signal from the first portion and not on the output signal from the second portion. If the speech signal is classified as non-periodic, the excitation signal is generated based on the output signal from said second portion and not on the output signal from said first portion.

Abstract: A digital transmission apparatus is provided, by which the amount of transmission delay and circuit miniaturization can be realized in the case of using an FEC method together with a differential coding method. In the digital transmission apparatus, a digital signal to be transmitted is serial-to-parallel-converted into parallel n-channel signals; each signal is FEC-encoded and encoded signals are then differentially encoded; and a carrier is modulated by the parallel n-channel differentially-encoded signals to be transmitted as a 2 n  multi-level modulated signal. The signal is detected at the receiving side and parallel n-channel demodulated and decoded signals are output; FEC decoding is performed; and the parallel n-channel digital signals after FEC decoding is parallel-to-serial-converted. When block coding is used as an FEC method, parallel n-channel digital signals to be transmitted are respectively processed by block-encoding of the same logic; the parallel n-channel signals after encoding are differentially encoded; and a carrier is modulated by the parallel n-channel differentially-encoded signals to be transmitted as a 2 n  multi-level modulated signal. At the receiving side, parallel n-channel signals after detection are stored; syndrome data for detecting an error bit position for each signal is calculated; and based on the syndrome data, time-series detection of each error bit position is performed so as to correct the errors included in the stored signals.

Abstract: The present invention relates to an apparatus and method for sending and receiving digital signals in a voice communication system (10). The apparatus includes a first subscriber analog telephone (12), a transmitter (13), a receiver (19) including a tone generator (20), and a second subscriber analog telephone (23). The transmitter (13) includes a tone detector (14), a first antenna (16), and a second antenna (18). In the preferred embodiment, the first subscriber analog telephone (12) is connected to the transmitter (13), and the second subscriber analog telephone (23) is connected to the receiver (19). The transmitter (13) receives an analog signal (11) carrying speech and DTMF signals from the first subscriber telephone (12). The transmitting unit (13) converts the analog speech signal into a digital speech signal. The tone detector (14) determines whether the digital speech signal contains any digit information, preferably dialed digits such as dual tone multifrequency (DTMF) tones, and encodes any detected digits into special tone packets. The transmitting unit (13) compresses the digital speech signal, replaces compressed speech packets with any special tone packets from the tone detector (14) if necessary, and transmits a digitally modulated and compressed output signal using the antenna (16) via an RF transmission channel. The digitally compressed signal is received by the receiver (19) using the second antenna (18). The tone generator (20) recovers any special tone packets in the received signal and generates a corresponding tone signal to be sent to the second telephone subscriber (23). The receiver (19) decompresses the digital speech signal and converts the signal to an analog speech signal (22) that is sent to the second subscriber telephone (23).

Abstract: The present invention relates to a furnace for very high working temperatures, and to a method of operating such a furnace. This high temperature - above 1800°C - is achieved by using resistor elements of stabilized zirconium dioxide. 
     An electrically heated furnace according to the invention includes an inner furnace chamber provided with resistor elements of stabilized zirconium dioxide, and an outer furnace chamber in which further resistor elements that can work at temperatures above 1800°C in an oxygen-containing atmosphere are provided. The outer resistor elements are conveniently of a molybdenum silicide type, for instance elements marketed under the designation KANTHAL Super. Those walls that delimit the inner furnace chamber are comprised of zirconium dioxide material or some other suitable material that has a low specific thermal conductivity and capable of withstanding the high working temperature and the occurrent temperature swings. The outer chamber, which completely surrounds the inner chamber, is delimited to the surroundings by conventional walls insulated, e.g., with ceramic fibres and/or high-temperature durable brick.

Abstract: A masking tape or sheet comprising a substrate comprising a resin
(a) comprising a polypropylene as a hard segment and an olefin copolymer
as a soft segment, and an adhesive layer formed on one side of said
substrate. The masking tape of the present invention can precisely
follow the shape of adhesion surfaces having curves, and can provide
fine parting lines. In particular, when polypropylene resin (b) is
added to the resin (a), the back face of the masking tape becomes smooth
and can be adhered easily with fingers, and the tape can be easily cut
with a cutter knife. Hence, the use of the masking tape of the present
invention leads to an improved efficiency of adhesion work, particularly
when the work is manually done. In addition, since the masking tape of
the present invention does not contain vinyl chloride in the substrate,
the masking tape after use can be incinerated without generating a
toxic gas such as chlorine gas.

Abstract: A connection procedure for finding by rearrangement a path for multirate, multicast traffic through an SDH cross-connect with subnetwork connection protection. If no free path for a new payload through the SDH switching hardware is available, the switching procedure looks for a path that is adequate and blocked by the least existing payload capacity. If the hunt is successful, the procedure rearranges the existing connections to make possible a path for the new payload. The procedure does not interrupt the existing connections; thus it is a "hitless" procedure. Connections for existing payloads that must be moved to make way for the new payload are queued and the connection procedure is applied recursively, to each in turn, until the queue is empty.
