  • Publication number: 20210269563
    Abstract: Provided are a decorative film for molding including a cholesteric liquid crystal layer on a base material, in which the cholesteric liquid crystal layer is a layer formed by curing a liquid crystal composition which includes, with respect to a total solid content of the liquid crystal composition, 25% by mass or more of a cholesteric liquid crystal compound having one ethylenic unsaturated group or one cyclic ether group; a molded product using the decorative film for molding; and a molding method.

  • Publication number: 20200303108
    Abstract: A common mode noise filter includes an insulating layer, a first coil conductor disposed on a first surface of the insulating layer and extending slenderly, and a second coil conductor disposed on a second surface of the insulating layer and extending slenderly. The second coil conductor faces the first coil conductor across the insulating layer. A portion of the second coil conductor has a cross section crossing a direction in which the portion of the second coil conductor extends slenderly. The cross section includes an apex portion facing the first coil conductor across the insulating layer and a base side portion opposite to the apex portion. A width of the apex portion is smaller than a width of the base-side portion. The common mode noise filter reduces attenuation of differential signals in high frequencies.

  • Patent number: 10147534
    Abstract: A common mode noise filter includes a first coil and a second coil. The first coil is formed in a plurality of insulating layers and includes a spiral first coil conductor and a spiral second coil conductor. The second coil is formed in the plurality of insulating layers and includes a spiral third coil conductor and a spiral fourth coil conductor. The first and third coil conductors are magnetically coupled to form a first common mode filter unit, and the second and fourth coil conductors are magnetically coupled to form a second common mode filter unit. As viewed from above, a first direction in which currents flow through the first and third coil conductors in the first common mode filter unit is opposite to a second direction in which currents flow through the second and fourth coil conductors in the second common mode filter unit.

  • Patent number: 9140778
    Abstract: Provided is a pulse radar device which can attenuate an interference signal and significantly amplify a reflected wave without saturating the interference signal. A baseband amplifier unit (5) is installed in a pulse radar device (1) which is configured to transmit from antenna (3) a transmission pulse wave obtained by modulating a transmission control signal, and to be afterwards switched to a standby mode for a reflected wave obtained by reflecting the transmission pulse wave by an object to be detected.
