  • Patent number: 11971315
    Abstract: Disclosed is a force sensor. More particularly, the force sensor includes a first permanent magnet layer; a magnetic tunnel junction disposed on the first permanent magnet layer and configured to have a preset resistance value; and a second permanent magnet layer disposed to be spaced apart from the magnetic tunnel junction, wherein the second permanent magnet layer moves in a direction of the first permanent magnet layer when pressure is applied from outside, the preset resistance value of the magnetic tunnel junction is changed when a magnetic field strength formed between the first permanent magnet layer and the second permanent magnet layer becomes a preset strength or more according to movement of the second permanent magnet layer, and the force sensor senses the pressure based on a change in the preset resistance value.

  • Publication number: 20240101954
    Abstract: The present invention relates to a Dunaliella salina OH214 strain having an improved ability to produce pigments, and in particular lutein. As it is possible to produce carotenoid pigments, specifically xanthophylls, with the Dunaliella salina OH214 strain by consuming less energy, it is possible to efficiently produce pigments at an industrial level. In addition, the Dunaliella salina OH214 strain can be applied as a raw material for foods, health functional foods, and pharmaceuticals, containing pigments. Moreover, the Dunaliella salina OH214 strain is a domestic native microalga in Korea and thus does not cause any GMO issues, it is possible to reduce costs by using seawater as a culture medium in Korea, and the effect of related industrial development can be expected.

  • Publication number: 20180030971
    Abstract: A variable-capacity swash plate-type compressor including: a lug plate coupled to a swash plate so as to be fixed to a driving shaft; and the swash plate coupled to the lug plate and having a varying inclination angle while making a rotational motion. The swash plate includes a body, and first and second arms that protrude from the body toward the lug plate and are spaced apart from each other. The lug plate includes a plate, a center lug arm that protrudes from the plate to be inserted between the first and second arms and is coupled to the body of the swash plate, and left and right lug arms that protrude from the plate to be spaced apart from each other and support both sides of each of the first and second arms.
