    Abstract: An optical path changing device includes: an optical member, a first support member that supports the optical member; a second support member that supports the first support member swingably about a first swing center line; a base member that supports the second support member swingably about a second swing center line; a first actuator that is disposed on one side with respect to the first swing center line and swings the first support member; and a second actuator that is disposed on one side with respect to the second swing center line and swings the second support member. The first swing center line is shifted toward the first actuator with respect to a shape center of the optical member at between the shape center of the optical member and the first actuator, or the second swing center line is shifted toward the second actuator with respect to the shape center of the optical member at between the shape center of the optical member and the second actuator.

    Abstract: A distance measuring device includes: a first imager and a second imager provided so as to be aligned such that fields of view thereof overlap each other; a projector configured to project pattern light in which a plurality of types of light regions having wavelength bands different from each other are distributed in a predetermined pattern, onto a range where the fields of view overlap; and a measurer configured to measure a distance to an object surface onto which the pattern light is projected, by performing a stereo correspondence point searching process on images respectively acquired by the first imager and the second imager.

    Abstract: Disclosed is a non-aqueous electrolyte secondary battery including: a negative electrode that contains a negative electrode material mixture; a separator, a positive electrode that is provided to oppose the negative electrode via the separator, and a non-aqueous electrolyte. The negative electrode material mixture contains a negative electrode active material. The negative electrode active material contains 3 mass % or more of a silicon-containing material. The silicon-containing material contains carbon composite particles. The carbon composite particles have a carbon phase and a silicon phase dispersed in the carbon phase. The non-aqueous electrolyte contains a 5- or 6-membered cyclic compound component that contains a sulfur element as a ring-constituting element.
