摘要： A carbon fiber composite material compact contains less of expensive carbon fibers, and the compact can therefore be used for general purposes which do not require highly superior physical properties. The carbon fiber composite material compact is produced by staking a first carbon fiber layer, a core layer, a second carbon fiber layer so as to form a laminate, and then compacting the laminate while impregnating an impregnable resin therein.

摘要： To present a demodulator of frequency modulated signals and a demodulating method of frequency modulated signals capable of demodulating frequency modulated signals having frequency deviation favorably. An input signal SIN (f±fDEV) having frequency deviation (±fDEV) from carrier frequency (f) is inputted in a signal converting unit 1, and an input square signal SSQ (f±fDEV) having same frequency as fundamental frequency is outputted. The input square signal SSQ mainly containing odd-number degree higher harmonics at fundamental frequency is put into a decoder 3, together with first signal SR (N×f) outputted at N times (N being 2 or greater natural number) of frequency of carrier frequency (f) from a signal output unit 2. The input square signal SSQ is converted by quadrature depending on the first signal SR, thereby producing two signals SI and SQ which are signals of N times of frequency (N×fDEV) of frequency deviation, inverted in phase difference by 90 degrees depending on the deviation. These two signals SI and SQ are logically operated and demodulated.
