  • Publication number: 20240111052
    Abstract: An information processing device (30) includes a signal acquisition unit (31), a passive depth estimation unit (34), and a fusion unit (35). The signal acquisition unit (31) extracts, from light reception data, active information indicating a flight time of reference light (PL) and passive information (PI) indicating two-dimensional image information of a subject (SU) obtained from ambient light (EL). The passive depth estimation unit (34) generates passive depth information (PDI) based on the passive information (PI). The fusion unit (35) fuses the passive depth information (PDI) with active depth information (ADI) generated based on the active information to generate depth information (DI) of the subject (SU).

  • Publication number: 20160216235
    Abstract: During filling of a capillary with an electrophoresis medium, this electrophoresis medium receptacle maintains a resting state, and the capillary and the electrophoresis medium receptacle are readily sealed. The electrophoresis medium receptacle is simple in shape, the electrophoresis medium receptacle is readily manufactured, and the electrophoresis medium is readily sealed. The amount of the electrophoresis medium sealed in the electrophoresis medium receptacle is brought into approximation without limit to the amount of the electrophoresis medium filling the capillary, minimizing dead volume. In this electrophoresis medium receptacle, a receptacle filled with an electrophoresis medium is maintained in a sealed state, and a septum which can be pierced by a capillary cathode end is provided. The pressure produced when the capillary cathode end pierces the septum in which the receptacle filled with the electrophoresis medium is sealed transports the electrophoresis medium into the interior of a capillary.

  • Publication number: 20160153936
    Abstract: The purpose of this invention has to do with being able to eliminate, using a small amount of an electrophoresis medium, air bubbles that get mixed in when loading an electrophoresis-medium container into a capillary electrophoresis device. This invention has to do with being able to simplify a positive-electrode-side channel in a capillary electrophoresis device by electrophoresing using only an electrophoresis medium on the positive-electrode side. This invention makes it possible to eliminate, easily and using a small amount of an electrophoresis medium, air bubbles that had become mixed in each time an electrophoresis-medium container was connected to the device. This invention also makes it easier to manage consumables and reduces the number thereof, making pre-electrophoresis preparation simple, and makes it possible to simplify and reduce the size of the device.

  • Publication number: 20120043211
    Abstract: Provided is a capillary electrophoresis apparatus capable of avoiding electric discharge even when a conductive component is arranged near a cathode end of a capillary. The capillary electrophoresis apparatus of the present invention has a structure in which a spatial distance and a creeping distance between an electrode attached to the cathode end of the capillary and the conductive component are large even when the conductive component is arranged near the cathode end of the capillary. That is to say, the capillary electrode, which protrudes from a lower surface of the load header, penetrates through a space between the load header and an anti-evaporation film and further penetrates through a capillary hole formed on the anti-evaporation film to extend into a container. At least a portion exposed to the space between the load header and the anti-evaporation film of the capillary electrode is covered with an insulating member.

  • Patent number: 7981267
    Abstract: An object of the present invention is to prevent a variation in heat dissipating effect of a capillary between a holder part and an oven, to improve reproducibility of migration time, and to reduce a variation of migration time among capillaries in a single electrophoresis run. A cylindrical wall is formed in an upper part of a septa that covers a container holding a solution, and the cylindrical wall surrounds a capillary hole through which a capillary penetrates. Accordingly, the capillary is prevented from being directly affected by wind generated between the septa and the oven.

  • Publication number: 20060108000
    Abstract: The fuel cut off valve comprises a casing, a float that rises and falls with increases and decreases in the buoyant force depending on the fuel liquid level within a valve chamber, and a valve mechanism that opens and closes a connecting passage through the rising or falling of the float, equipped on the upper part of the float. The valve mechanism comprises a supported part, and when the supported part is supported by a support part of the float, the center of gravity is provided below the support portion, so that the supported part is balanced on a single support portion. The fuel cut off valve can provide excellent seal performance when a vehicle is at an angle, and that can be miniaturized.
