  • Patent number: 10732335
    Abstract: Provided are a polarizing plate having excellent optical characteristics, and a method for manufacturing the polarizing plate. The present invention is provided with: a translucent substrate through which light passes in a working band; a bundle structure layer constituted of a columnar sheaf comprising one or more material from among dielectrics, metals, and semiconductors, the bundle structure layer being formed on the translucent substrate; an absorption layer formed on the bundle structure layer; a dielectric layer formed on the absorption layer; and a reflection layer formed on the dielectric layer and arranged as a one-dimensional lattice at a pitch that is smaller than the wavelength of the light in the working band. Because the bundle structure layer increases light absorption and light scattering, the result is that reflectivity can be reduced and excellent optical characteristics obtained.

  • Publication number: 20140286458
    Abstract: An RF-LSI receives a first signal transmitted with a first system frequency and a second signal transmitted with a second system frequency. In the RF-LSI 50, a frequency converter 55 performs frequency conversion on the received first signal (i.e., a master-received signal) and the received second signal (i.e., a slave-received signal) such that the first signal and the second signal do not overlap each other on the frequency axis and the frequency of each of the first signal and the second signal falls within a range containing a reference frequency and having a predetermined bandwidth. A mixer mixes the first signal subjected to the frequency conversion and the second signal subjected to the frequency conversion. An ADC performs analog-to-digital conversion on the mixed signal.
