    摘要： The present invention relates to a thermosetting low dielectric resin composition, a laminate for use in printed wiring, a laminate for a circuit, and the like. The present invention's thermosetting low dielectric resin composition contains a specific siloxane denatured polyimide, a compound having two or more allyl or methylallyl groups, and a compound having two or more maleimide groups. This resin composition adheres extremely well to metals with a low dielectric constant and low dielectric dissipation factor, and demonstrates very little scattering of the resin during operational processes like punching or cutting. By using laminates or laminates for circuits that employ this resin composition, electrical signals can be propagated more quickly, enabling signals to be processed at faster speeds. In addition, the present invention can be applied to the formation of miniaturized circuit wiring, and is suitably employed in electronic devices employed in the high frequency region, and, in particular, in electronic devices that must be made smaller and lighter in weight.

    摘要： A method of manufacturing a semiconductor device including the steps of: forming a transparent oxide film on a light reflecting surface; forming an anti-reflective a-c film on the surface of the transparent film; and coating a photoresist film on the surface of the anti-reflective film and patterning the photoresist film, wherein the thicknesses of the anti-reflective film and the transparent film are selected so as to set a standing wave intensity Isw=I&dgr;/Iave to 0.2 or smaller, where Iave is an average value of light intensity in the photoresist film, and I&dgr; is an amplitude of a light intensity change. A fine pattern can be formed on a highly reflective substrate with a small size variation and at a high precision.

    摘要： A method and an apparatus for recording and reproducing a PCM audio signal either alone or together with a video signal, using a rotary-head type scanner. An analog audio signal is converted into a digital signal having a predetermined number of quantization bits in each predetermined sampling period. The digital signal is recorded on a recording medium such as a magnetic tape, and an analog audio signal is reproduced from the digital signal reproduced from the recording medium. In the reproducing mode, the signal reproduced from the tape is written into a memory where error detection, correction and deinterleaving are carried out, and the signal is then read from the memory and applied to a D/A converter. The write rate from the memory depends on the video field period, and the read rate depends on the sampling period. Accordingly, the difference between the write address and the read address of the memory depends on the difference between the field period and the sampling period. By changing a master clock, which defines the sampling period controlled by the read address, in accordance with the address difference, the difference between the video signal field period and the audio signal sampling period can be controlled and compensated.

    摘要： In a recording operation by a rotary head type PCM recording/reproducing apparatus including at least two magnetic heads, the odd-numbered sample data and the even-numbered sample data are discriminatively extracted and stored. The stored data corresponding to an amount of data outputted from the A/D converter within a predetermined time is selectively read out and supplied to the two heads to thereby record the data in such a manner that the odd-numbered data and the even-numbered data are recorded separately on a track basis or alternatively recorded separately on a preceding half and a succeeding half of each track. The error detecting and correcting code is prepared on the basis of the data to be recorded in each track. In reproduction of the recorded data, upon detection of a drop-out of the data from one of the two heads, the drop-out data is corrected through interpolation procedure to thereby reconstitute the original analog signal.

    摘要： Error detection/correction codes appended to a recording signal for a PCM recorder are so arranged as to ensure detection and/or correction of a dropout or error of a data block address in the reproduction of the recording signal. In recording digital signals on a recording medium, the digital signals are formatted in n-word blocks, each block further including a sync signal for providing a reference timing for the reproduction of the signal, control data related to the digital signals, a data block address for identifying the block of n-words, an error detection code for detecting an error in the control data and the block address, and an error detection/correction code for error detection and/or correction for the block address and the n-words. A recording system includes an error detection/correction code generating circuit which generates error detection/correction codes using a Reed Solomon code or b-adjacent code. The generated error detection/correction codes are combined by a multiplexer so that a recording signal is arranged, and recorded on the recording medium.
