Title: Automatic frequency control circuit
Inventor: KITAYAMA TAKAMITSU
IPC: H03J7/06
Filed: 1991-02-05
Abstract: This AFC circuit stabilizes the frequency of an intermediate frequency signal to be applied to a demodulation circuit (2). A frequency conversion circuit (1) responds to a local oscillation signal generated from a voltage-controlled oscillation circuit (309) to convert the frequency of a digital modulation signal and apply the converted frequency to the demodulation circuit. A carrier reproduction circuit (203) in the demodulation circuit reproduces the carrier of the intermediate frequency signal to output a synchronizing detection signal (306). The frequency of the reproduced carrier is frequency-demultiplied by a frequency demultiplying circuit (310). A frequency demultiplication output thereof is counted by a counter (311) for a definite period. Data is output from a microprocessor (307) in response to a count output of the counter and the synchronizing detection signal and then converted into an AFC voltage by a D/A converter (308). The converted voltage is supplied as a control voltage to the voltage-controlled oscillation circuit. A stable intermediate frequency signal can be obtained by frequency-demultiplying the frequency of the carrier and counting the frequency demultiplication output thereof.

IPC: G09G5/10

Abstract: The brightness of an X-ray video image during fluorography is maintained at a substantially constant level varying the X-ray dose in relation to changes in the average brightness of the X-ray image. As the X-ray system approaches the limits of its imaging capability, varying the X-ray dose alone may not yield the desired brightness level. At this point, the gain applied to the video signal is increased to improve the brightness. A linear brightness taper function is used such that, as the level of video gain required to maintain constant brightness increases, the actual video gain increases by a smaller proportional amount. This function results in the brightness of the video image decreasing somewhat as the video gain is required to provide a greater degree of brightness compensation. This reduction in brightness not only provides a visual indication to the image observer that the system is approaching the imaging limits, but also creates an illusion that noise artifacts in the image are not intensifying as the video gain increases.

Abstract: In a semiconductor optical modulator, two semiconductor materials having different refractive indices are grown in an alternating sequence of layers (11-15) to form a semiconductor mirror wherein each layer has approximately a quarter wave thickness for a predetermined wavelength. Delta doping (δn,δp) is performed at each heterointerface. The delta doping conductivity type alternates from one heterointerface to the next. Lateral surface contacts are selectively made to the n-type heterointerfaces on one edge of the mirror (17) and to the p-type heterointerfaces on the other edge of the mirror (21). An interleaved ohmic contact structure results within the modulator. By applying a nominally low voltage to the lateral surface contacts, it is possible to effect refractive index changes in the layers so that the mirror performs reflection or transmission of an impinging light beam (19).

Abstract: The invention concerns a lamp having a reflector, a glass lid and a filament which is supported by supply wires. The supply wires pass from the interior of the lamp to the outside through the connecting area between the reflector and the glass lid. The reflector is thus almost 100 percent effective because there is no space required for a material collection marking a passage of supply wires or a socket for receiving a bulb. The light performance of the lamp is thus an optimum.

Abstract: In speech recognition and speech coding, the values of at least two features of an utterance are measured during a series of time intervals to produce a series of feature vector signals. A plurality of single-dimension prototype vector signals having only one parameter value are stored. At least two single-dimension prototype vector signals having parameter values representing first feature values, and at least two other single-dimension prototype vector signals have parameter values representing second feature values. A plurality of compound-dimension prototype vector signals have unique identification values and comprise one first-dimension and one second-dimension prototype vector signal. At least two compound-dimension prototype vector signals comprise the same first-dimension prototype vector signal. The feature values of each feature vector signal are compared to the parameter values of the compound-dimension prototype vector signals to obtain prototype match scores. The identification values of the compound-dimension prototype vector signals having the best prototype match scores for the feature vectors signals are output as a sequence of coded representations of an utterance to be recognized. A match score, comprising an estimate of the closeness of a match between a speech unit and the sequence of coded representations of the utterance, is generated for each of a plurality of speech units. At least one speech subunit, of one or more best candidate speech units having the best match scores, is displayed.

Abstract: 2.1 Known filters for separating out solids from the exhaust gases of an auto-igniting internal combustion engine, where the filter can be regenerated by burning off the deposited solids and the burning-off process can be initiated by electrical heating of the filter, have the disadvantage that at least under certain operating conditions, only incomplete burning-off of solids is achieved. This is due to the fact that the solids deposit on the filter upstream of the electrical heating in the flow direction and these layers deposited upstream in particular in the case of exhaust gas flowing through the filter during the regeneration process are insufficiently heated for initiating the burning-off process. 2.2 According to the invention, the filter is heterogeneously constructed, divided into a coarse-pore layer 1 and a fine-pore layer 2, the exhaust gas initially flowing through the coarse-pore layer 1 before the solids are separated out from the exhaust gas stream by the fine-pore layer 2. At the same time, the coarse-pore layer 1 is designed to be electrically conducting, so that during a regeneration process, complete burning-off of solids is ensured. <IMAGE>

Abstract: An earth leakage or differential current circuit breaker (residual current device) has contact points (17) (which are arranged in a network having at least one forward conductor and one return conductor), a transformer (10) whose primary windings (11, 12) are formed by the network conductors and whose secondary winding (15) is connected to a tripping relay (17), via a storage circuit (16). The tripping relay (17) acts on the latching point in a latching mechanism (18), and the latching mechanism acts on the contact points (19). In order to avoid failures after a relatively long operating time or towards the end of the useful life of the tripping device (17), the storage circuit (16) has an evaluation circuit (20) which is connected to the tripping relay (17) via a signal line (21). As a result of the armature movement of the tripping relay (17), a pulse signal, which is detected by the evaluation circuit (20), is produced during the tripping process. If this pulse signal does not occur as a result of the tripping relay (17) not tripping, then the tripping energy emitted by the store of the storage circuit (16) is increased.   <IMAGE>
