  • Publication number: 20190198227
    Abstract: The inventors have newly found that, even when a composition of a first element body portion and a composition of a second element body portion are different from each other, a high bonding strength at an interface between the first element body portion and the second element body portion can be obtained when both the first element body portion and the second element body portion contain Zn2SiO4 as a constituent component. That is, when the first element body portion and the second element body portion contain Zn2SiO4, a bonding strength at the interface is improved compared to a case in which the first element body portion and the second element body portion do not contain Zn2SiO4.

  • Publication number: 20190198232
    Abstract: In a multilayer coil component, a ferrite element body includes a first element body portion and a second element body portion adjacent to each other in an axial direction of the multilayer coil, in which a dielectric constant of the second element body portion is lower than a dielectric constant of the first element body portion, and a magnetic permeability of the second element body portion is higher than a magnetic permeability of the first element body portion. The inventors newly found that the first element body portion and the second element body portion contribute to coil characteristics when a coil winding portion is provided to extend over the first element body portion and the second element body portion. In the multilayer coil component, desired coil characteristics can be obtained by adjusting proportions of the first element body portion and the second element body portion in the ferrite element body.

  • Patent number: 10263654
    Abstract: A radio frequency signal can be received in an intermediate frequency mode suitable for radio wave reception conditions. An oscillator has a variable oscillation frequency. A quadrature demodulator includes a frequency mixer and generates an intermediate frequency signal having an intermediate frequency lower than the frequency of the radio frequency signal. An ADC receives the intermediate frequency signal passed through an analog filter and converts the received intermediate frequency signal to a digital signal. A channel selection signal processing section generates a demodulated signal from the intermediate frequency signal converted to the digital signal. A mode control section switches the operating mode of the quadrature demodulator between a zero intermediate frequency mode and a low intermediate frequency mode in accordance with the radio wave reception conditions.
