Master information carrier, process for producing the carrier, and method and apparatus for recording master information signal on magnetic recording medium by using the carrier

Abstract: A master information carrier comprises a substrate whose surface has an embossed pattern corresponding to an information signal. At least a surface of the protruding portion of the embossed pattern is made of a ferromagnetic material. A method for writing an information signal into a sheet or disk magnetic record medium with a ferromagnetic thin film or coating is performed by putting the surface of the magnetic record medium into contact with the master information carrier so as to write a magnetized pattern corresponding to the embossed pattern of the master information carrier into the magnetic record medium.

Base station apparatus and radio communication method

Abstract: A base station (10) performs bidirectional radio communication with a terminal station apparatus by using a time division communication frame consisting of a first region having a predetermined open loop cycle and a second region having an open loop cycle shorter than the first region. A level detection block (21) detects a reception level of an uplink slot arranged in the second region. A transmission diversity block (14) diversity-transmits a downlink transmission signal allocated to a downlink slot corresponding to the aforementioned uplink slot in accordance with the detection result of the reception level. Thus, it is possible to enhance the improvement effect of the reception quality by the transmission diversity without lowering the transmission efficiency.

Formant-based speech synthesizer employing demi-syllable concatenation with independent cross fade in the filter parameter and source domains

Abstract: The concatenative speech synthesizer employs demi-syllable subword units to generate speech. The synthesizer is based on a source-filter model that uses source signals that correspond closely to the human glottal source and that uses filter parameters that correspond closely to the human vocal tract. Concatenation of the demi-syllable units is facilitated by two separate cross face techniques, one applied in the time domain in the demi-syllable source signal waveforms, and one applied in the frequency domain by interpolating the corresponding filter parameters of the concatenated demi-syllables. The dual cross fade technique results in natural sounding synthesis that avoids time-domain glitches without degrading or smearing characteristic resonances in the filter domain.

Television receiver, recording and reproduction device, data recording method, and data reproducing method

Abstract: A television receiver comprises a tuner for receiving a television video signal; data storage means including a data storage unit for storing the video signal received by the tuner, for its storage capacity, a writing pointer for time-sequentially writing the video signal into the data storage unit, and a reading pointer for reading the stored video signal; select means for selecting and outputting one of the reproduced video signal output from the data storage means and the video signal received by the tuner; and control means for controlling the data storage means and the select means in response to an external input signal.
