  • Patent number: 10812096
    Abstract: A wireless communication device converts a signal component, which has one of distributed frequency bands in an analog RF signal and passes through one of a plurality of bandpass filters, into digital data with an AD converter that carries out undersampling. A sampling frequency of the AD converter is set so that frequencies which are integral multiples of a Nyquist frequency based on the sampling frequency do not fall within frequency bands of signal components which are of the RF signal and are to pass through the respective plurality of bandpass filters.

  • Patent number: 10369520
    Abstract: The exhaust gas cleaning catalyst according to the present invention is provided with a cylindrical substrate 10 and a catalyst coat layer 20 formed on the surface of the substrate 10. A ratio of the length L in the cylindrical axis direction of the substrate 10 and the diameter D of a cross section orthogonal to the cylindrical axis direction is denoted by (L/D)?0.8. The coat density of the catalyst coat layer 20 differs between an upstream side portion 10a that includes the exhaust gas inlet-side end 16 of the substrate 10 and a downstream side portion 10b that includes the exhaust gas outlet-side end 18 of the substrate 10. The coat density A in the upstream side portion 10a is lower than the coat density B in the downstream side portion 10b (A<B).
