  • Publication number: 20240125635
    Abstract: To enable accurate measurement of a flow rate of a gas flowing in a non-metallic tube. An ultrasonic flowmeter includes a first wedge member having a first angle, a second wedge member having a second angle, and a flow rate measurement unit that measures a flow rate of a gas based on a propagation time difference of a longitudinal wave excited by a tube. The first angle and the second angle are configured such that the tube excites both a longitudinal wave and a shear wave, and a mixing ratio of the shear wave to the longitudinal wave is 10% or less.

  • Patent number: 11685067
    Abstract: The present disclosure provides an electric razor that can further suppress irritation to a skin. An electric razor of the present disclosure includes a body configured to be gripped by a user, a head having three or more blade blocks, and a head support connecting the head and the body to each other. The head support supports the head in a floatable-and-sinkable way with respect to the body. The head includes a case that supports the three or more blade blocks, and a blade float that allows each of the three or more blade blocks to float and sink with respect to the case. A first urging force with which the head support urges the head in a floating direction is larger than a second urging force with which the blade float urges the plurality of blade blocks which are one or more less than three or more blade blocks in a floating direction. The first urging force is smaller than a third urging force with which the blade float urges all of the three or more blade blocks in the floating direction.
