摘要： An envelope (2) has a glass bulb body (4) and a cylindrical glass bulb base (5). The glass bulb body (4) includes an upper hemisphere (4a) and a lower hemisphere (4b). The upper hemisphere (4a) is curved in a substantially spherical shape. The lower hemisphere (4b) is substantially curved in a spherical shape and connects the upper hemisphere (4a) and glass bulb base (5). A photocathode (11) is formed on the inner surface of the glass bulb body (4). An avalanche photodiode (APD) (15) is disposed on the glass bulb body (4) side relative to an intersection (S) between an imaginary extended curved surface (I) of the lower hemisphere (4b) within the glass bulb base (5) and an axis (Z). When light enters the photocathode (11), electrons are emitted from the photocathode (11). The electrons are converged at the position above and in the vicinity of the APD (15) by an electrical field in the electron tube (1), so that the electrons enter the APD (15) in an efficient manner and are detected satisfactorily.

摘要： An error control encoding method and a mobile data communication system using the method in a moving body communication system such as mobile telephone for effecting data communication through a fading channel dominated by a burst error, upon receiving data transmitted from the transmitting side on the receiving side, detects any error involved in said received data as a frame error rate involved in block data or a bit error rate in the block data and thereby changes the frame length in response to the detected error rates. The mobile data communication system employs the error control encoding method wherein a frame length employed in the transmitting part is changed in response to the extent of any involved error in the received data detected by the remote receiving part.

摘要： Features are extracted from a sample input signal by performing first linear predictive analyses of different first orders p on the sample values and performing second linear predictive analyses of different second orders q on the residuals of the first analyses. An optimum first order p is selected using information entropy values representing the information content of the residuals of the second linear predictive analyses. One or more optimum second orders q are selected on the basis of changes in these information entropy values. The optimum first and second orders are output as features. Further linear predictive analyses can be carried out to obtain higher-order features. Useful features are obtained even for nonstationary input signals.

摘要： A circuit for pattern matching on the frequency axis which inlcudes a first transformation section having an adaptive filter which is generally identical to an adaptive finite impulse response filter, but with its delay elements having been replaced by all-pass filters. The first transformation section performs frequency transformation on an input signal and is characterized by utilizing as tap coefficients for the adaptive filter, linear predictive analysis coefficients of the input speech signal. The first transformation section outputs linear predictive analysis coefficients of the frequency transformed input signal. A second transformation section is similar to the first transformation section but the tap coefficients of its adaptive filter are linear predictive analysis coefficients of a reference speech signal. A control section calculates a distance between the respective linear predictive analysis coefficients output from the first and second transformation sections, calculates controlling parameters of the filters of the all-pass filters of the transformation sections so as to minimize this distance, and generates a pattern matching residual output on the frequency axis.

摘要： An error correcting encoding method and a vehicle data communication apparatus based on the same for use in data communication via fading communication channels dominated by burst errors in the data communication among vehicles such as automobiles are disclosed. The error correction encoding method detects, as data sent from a transmitting side is received by a receiving side, any error contained in the received data as a frame error rate of error frames involved in block data or a bit error rate of error bits involved in the block data and selects an error correcting code in response to the frame error rate for encoding. The vehicle data communication apparatus according to the present invention profitably employs the method, and changes an error correcting code to be used on the transmitting side in response to the extent of errors involved in the received data detected by the receiving side of a remote apparatus.

摘要： In a block-spreading code-division multiple-access communication system a demodulator stores received chip data in a separate memory area for each transmitting station. Each area has a capacity of at least two blocks. When a complete block is received from a transmitting station, all blocks of data stored in the corresponding memory area are correlated against a set of product codewords, which are obtained by spreading a set of orthogonal codewords by the transmitting station's spreading code, to find the codeword that gives the maximum correlation value. For the oldest block, this correlation value and information identifying the codeword are output. For all blocks, the maximum correlation value and corresponding product codeword are used to calculate interference correction data, which are subtracted from the data in other memory areas.
