  • Publication number: 20210009046
    Abstract: An ultrasonic sensor includes: an ultrasonic element provided to transmit or receive an ultrasonic wave propagating along a directional axis; and an element housing case that includes a case diaphragm having a thickness direction along the directional axis. A resonant space is defined between the case diaphragm and the ultrasonic element for the propagating wave, by housing the ultrasonic element while separating the ultrasonic element from the case diaphragm. A horn shape is defined in the element housing case in which a width of the resonant space in a direction orthogonal to the directional axis is reduced as the resonant space extends in an axial direction parallel to the directional axis.

  • Patent number: 10413895
    Abstract: When the amount of coating is increased in a two-layer catalyst or the like containing two noble metals in respective different layers, gas diffusivity in the catalyst and use efficiency of a catalytic active site are reduced to thereby reduce purification performance. In view of this, an organic fiber having a predetermined shape is used as a pore-forming material in formation of an uppermost catalyst coating layer of a multi-layer catalyst, to thereby form an uppermost catalyst coating layer having a high-aspect-ratio pore excellent in connectivity and therefore excellent gas diffusivity.
