Abstract: A demodulator for demodulating a phase shift keying signal to regenerate a data signal. The demodulator comprises a clock generator for generating three-phase clock signals which are of substantially the same frequency as a carrier frequency of the phase shift keying signal and 120.degree. out of phase from each other, phase difference detectors for detecting phase differences of the phase shift keying signal relative to respective three-phase clock signals, a timing extractor for producing a data clock signal by fetching the three-phase clock signals and detected phase differences, and a phase difference change detector for producing the data signal by detecting the presence or absence of a change of phase difference between portions of the phase shift keying signal corresponding to preceding and succeeding bits of the data clock signal.

Abstract: An electrically conductive paste is disclosed, which comprises (i) 60 to 90 wt % of metal fine powders comprising a silver fine powder, a composite fine powder of silver and copper and optionally either, a composite fine powder of silver and platinum or a platinum fine powder, or a composite fine powder of silver and palladium or a palladium fine powder, the copper content in the metal fine powders is 0.1 to 10 wt %, the platinum content, if present, is 0.2-10 wt % and the palladium content, if present, is 0.2-30 wt %, and (ii) 10 to 40 wt % of a vehicle component, such as terpineol, butylcarbitol, ethyl cellulose etc. The product can resist thermal shocks and has strong bonding strength having remarkably improved heat deterioration characteristics.

Abstract: A high impact polyamide composition comprising in specific weight proportions a polyamide, an ethylene ionomer resin and an elastomeric ethylene copolymer, said ethylene ionomer resin and said elastomeric ethylene copolymer having specific relationships with respect to melt index, which exhibits excellent impact strengths at not only ordinary temperatures but also low temperatures along with remarkable improvements in other physical properties such as heat resistance, while maintaining good processability, inclusive of good moldability.
