  • Optical waveguide device, manufacturing method of optical modulation element, optical modulator, optical modulation module, and optical transmission apparatus
    Patent number: 11977284
    Abstract: There is provided an optical waveguide device including: a substrate; an optical waveguide formed on the substrate; and a working electrode that controls a light wave propagating through the optical waveguide, in which the working electrode includes a first base layer made of a first material, a first conductive layer on the first base layer, a second base layer made of a second material different from the first material, which is on the first conductive layer, and a second conductive layer on the second base layer, and an edge of the second base layer is covered with the second conductive layer, in a cross-section perpendicular to an extending direction of the optical waveguide.

  • Valve actuator for an electrically actuated poppet valve including a continuously variable transmission and a power free latching mechanism
    Patent number: 10527189
    Abstract: A valve actuator is a valve actuator that drives opening and closing of a poppet valve and includes a motor and a transmission mechanism that transmits a drive force of the motor to the poppet valve. The transmission mechanism includes a booster mechanism. The booster mechanism is a three-dimensional toggle mechanism that includes a cylinder, an input disc that rotates about an axis in the cylinder, an output disc that reciprocates along an axial direction in the cylinder, and a link that connects the input disc and the output disc.
