  • Patent number: 11898190
    Abstract: A method for producing a microbial oil includes steps of: genetically modifying a labyrinthulid by disrupting and/or silencing a gene, or by transforming another gene in addition to the disruption and/or gene silencing of the gene, and culturing the labyrinthulid, such that a fatty acid composition accumulated in the labyrinthulid comprises an increased EPA content; and collecting the microbial oil having the increased EPA content from the labyrinthulid. The labyrinthulid before the modification is selected from (A) a labyrinthulid belonging to the genus Parietichytrium or genus Schizochytrium and having very weak or no activity of producing PUFAs via a PUFA-PKS pathway; and (B) a labyrinthulid belonging to the genus Thraustochytrium in which a host PUFA-PKS gene is disrupted or silenced to a very weak level.

  • Patent number: 11225090
    Abstract: An ultrasonic sensor includes a first base facing a conveying surface, a transmission section on a first axis tilted relative to the conveying surface and at a far side of the first base for transmitting an ultrasonic wave toward the first axis, and a reception section on the first axis and at a far side of the conveying surface for receiving the ultrasonic wave. The transmission section has a plurality of transmission elements for transmitting the ultrasonic wave arranged to cross the first axis. The first base has a first aperture through which the ultrasonic wave transmitted from the transmission section along the first axis passes. An area of the first aperture is smaller than an area of an ultrasonic wave transmission surface of the transmission section. The transmission section delays driving the transmission elements to converge the ultrasonic wave transmitted from the transmission section toward the first aperture.
