  • Patent number: 11435571
    Abstract: An optical scanning device includes: a first mirror; a second mirror opposed to the first mirror; two non-waveguide regions sandwiched between the first mirror and the second mirror; an optical waveguide region disposed between the two non-waveguide regions; and two intermediate regions. The average refractive index of the optical waveguide region is higher than the average refractive index of each intermediate region. The average refractive index of each intermediate region is higher than the average refractive index of each non-waveguide region. The first mirror allows part of light propagating through the optical waveguide region to be emitted as emission light in a third direction. By changing the refractive index and/or thickness of the optical waveguide region, the third direction, which is the emission direction of the emission light, is changed.

  • Patent number: 10029436
    Abstract: Provided are an electrolytic cathode structure that can suppress the degradation of an activated cathode even if a reverse current flows upon the stoppage of operation of an electrolyzer in an electrode structure allowing the distance between the electrode and an electrode current collector to be maintained at an approximately constant value, and an electrolyzer using the same. The electrolytic cathode structure includes a metal elastic cushion member 1 compressed and accommodated between an activated cathode 2 and a cathode current collector 3. At least a surface layer of the cathode current collector 3 consumes a larger oxidation current per unit area than the activated cathode. The electrolyzer is partitioned by an ion exchange membrane into an anode chamber for accommodating an anode and a cathode chamber for accommodating a cathode. The electrolytic cathode structure is used for the cathode.
