Abstract: A vehicle control apparatus includes front-wheel and rear-wheel driving systems, and a control system. The front-wheel driving system includes a first travel motor mechanically coupled to a front wheel of a vehicle and a first accumulator electrically coupled to the first travel motor. The rear-wheel driving system includes a second travel motor mechanically coupled to a rear wheel of the vehicle and a second accumulator electrically coupled to the second travel motor. The control system includes one or more processors and one or more memories communicably coupled to the one or more processors, and controls the first and second travel motors. When a difference between an SOC of the first accumulator and an SOC of the second accumulator is greater than a threshold value, the one or more processors change a torque distribution ratio between the first and second travel motors from a reference distribution ratio.

Abstract: An analysis device uses an analysis chip having two regions of a first region, which has a reagent reacting with a substance to be tested, and a second region, which does not have the reagent, and includes a first light source that irradiates the first region with light from a first surface side, a second light source that irradiates the second region with light from a second surface side, a first photodetector that detects first output light and that outputs a first detection signal corresponding to the first output light, a second photodetector that detects second output light and that outputs a second detection signal corresponding to the second output light, and a processor that acquires the first detection signal, acquires the second detection signal, and corrects the first detection signal with the second detection signal to derive a concentration of the substance to be tested.

Abstract: An analysis device uses a single or a plurality of analysis chips having two regions of a first region, which has a reagent reacting with a substance to be tested, and a second region, which does not have the reagent. The analysis device includes a light source that irradiates the analysis chip with light, a photodetector that detects output light, which is output from the analysis chip, and that outputs a first detection signal corresponding to the output light from the first region and a second detection signal corresponding to the output light from the second region, and a processor that acquires the first detection signal and the second detection signal from the photodetector and that corrects the first detection signal with the second detection signal to derive a concentration of the substance to be tested included in the sample.

Abstract: Disclosed is a liquid sending method using a sample processing chip having a flow path into which a plurality of liquids flow, and the method includes: sending, into the flow path, a first liquid held in a liquid holding portion provided in the sample processing chip by applying pressure to the liquid holding portion; sending, into the flow path, a second liquid in a storage portion provided in a liquid sending device connected to the sample processing chip, through an injection hole provided in the sample processing chip, by applying pressure to the storage portion; and forming, in the flow path, a fluid containing the first liquid having been sent from the liquid holding portion, and the second liquid having been sent through the injection hole.

Abstract: Disclosed is a nucleic acid detection device which includes an installation unit on which a cartridge is installed, the cartridge including a chamber configured to store nucleic acid, a reagent for amplifying the nucleic acid and a dispersion medium for dispersing the nucleic acid and the reagent; a sample processing unit configured to produce, within the chamber, an emulsion in which droplets containing the nucleic acid and the reagent are dispersed in the dispersion medium; a temperature regulating unit configured to regulate a temperature of the cartridge to amplify the nucleic acid contained in the droplet; and a detection unit configured to detect a signal based on the nucleic acid amplified by temperature regulation by the temperature regulating unit.

Abstract: According to one or more aspects, a specimen processing method may use a cartridge comprising a chamber configured to store a liquid. The method may include: storing a specimen and a dispersion medium in the chamber of the cartridge; and rotating the cartridge about a rotational shaft to agitate the specimen and the dispersion medium in the chamber, to thereby form an emulsion in which a dispersoid containing the specimen is dispersed in the dispersion medium.

Abstract: A particle imaging apparatus comprises a flow path comprising a first flow path section, a second flow path section connected downstream of the first flow path section, and a third flow path section that is branched from the first flow path section, a particle detection unit comprising a light source and a light detector, a particle sorting unit configured to adjust a flow direction of the particle, and a particle imaging unit configured to take an image of a particle that flows in the second flow path section. The flow path is structured such that a cross-sectional area of the second flow path section is greater than a cross-sectional area of the first flow path section. The first flow path section and the second flow path section are disposed so as to be linearly aligned.

Abstract: Disclosed is a specimen processing chip installed in a liquid feeder, comprising a flow path into which a first liquid and a second liquid flow, a first well having a first injection port into which the first liquid is injected by an operator, and a first liquid feed port for feeding the first liquid injected from the first injection port to the flow path, that is smaller in diameter than the first injection port, a second well having a second injection port into which the second liquid fed from the liquid feeder is injected, and a second liquid feed port for feeding the second liquid injected from the second injection port to the flow path, that is smaller in diameter than the second injection port, and an identification section for distinguishing between the first injection port and the second injection port.
