  • Publication number: 20240068925
    Abstract: A particle analyzer (100) includes: a light source that emits excitation light (EL1) including light having a wavelength of 400 nm or less; a lens structure (41) that collects excitation light (EL1) at a predetermined position (51s) in a flow path (53); a detection unit (7) that detects light (FL) emitted from a particle as the particle (51) flowing through the predetermined position is excited by the excitation light (EL1); and a processing unit (120) that processes detection data acquired by the detection unit (7). The lens structure (41) includes a plurality of lenses (411) arranged along an optical axis of the excitation light (EL1); and a lens frame (412) holding the plurality of lenses (411). At least one (G12) of the plurality of lenses (411) is positioned in the lens frame (412) by abutting on a lens adjacent to the lens.

  • Patent number: 11815756
    Abstract: An information display device attachable to a structure includes a display panel and a surface member. The display panel has a display surface and is configured to display information on the display surface. The surface member is a surface member disposed on a display surface side of the display panel, and has a larger surface area than the display panel. When the display panel is turned on, only the information displayed on the display surface of the display panel becomes visible through the surface member.

  • Patent number: 11605362
    Abstract: The information display device includes a surface member, a display, a light measurement unit, and a controller. The surface member is at least partially transmissive for light. The display is disposed on a back side of the surface member and is capable of displaying a display image including an information area for displaying information and a non-information area for displaying no information. The light measurement unit measures the amount of ambient light around the information display device. The controller acquires the amount of light measured by the light measurement unit and changes a pixel value of a display image according to the amount of light so that the display is difficult to be seen through a surface of the surface member.
