  • Publication number: 20240134220
    Abstract: An optical scan device includes an optical waveguide array, including a plurality of optical waveguides each of which propagates light along a first direction, that emits a light beam, the plurality of optical waveguides being arranged in a second direction that intersects the first direction, a phase shifter array including a plurality of phase shifters connected separately to each of the plurality of optical waveguides, a control circuit that controls a phase shift amount of each of the plurality of phase shifters and/or inputting of light to each of the plurality of phase shifters and thereby controls a direction and shape of the light beam that is emitted from the optical waveguide array, a photodetector that detects the light beam reflected by a physical object, and a signal processing circuit that generates distance distribution data on the basis of output from the photodetector.

  • Publication number: 20180125045
    Abstract: A buzz bait lure includes a wire, and a blade disposed to rotate around the wire. The blade includes a propeller portion at one side of the blade; a front support portion; and a rear support portion positioned at a side closer to the propeller portion than the front support portion and having a third hole. The front or rear support portion includes a rising portion rising from a flat surface of the blade and having a first hole, and a folding portion having a second hole and folded from the rising portion to face the flat surface of the blade. The blade is supported on the wire at the front support portion and the rear support portion, and the wire is inserted into at least the first hole, the second hole, and the third hole.

  • Publication number: 20130273166
    Abstract: A method for enlarging a breast includes the step of administering to a subject in need thereof a composition that includes a fine particle of calcium phosphate. The fine particle of calcium phosphate may be a fine particle of hydroxyapatite. An average particle size of the fine particle of calcium phosphate is 10 to 1,000 nm. The fine particle of calcium phosphate may be a sintered body. The sintered body may be manufactured by a method including: a mixing step in which a primary particle containing calcium phosphate is mixed with a fusion inhibitor, and a sintering step in which the mixed particle obtained by the mixing step defined above is exposed to a sintering temperature.
