  • Patent number: 12504438
    Abstract: Provided is an automatic analyzer in which a lid of a reagent vessel does not hinder the dispensing of the reagent. An automatic analyzer for analyzing a specimen includes a reagent dispensing unit for dispensing a reagent from a reagent bottle in which a plurality of reagent vessels storing reagents used for the analysis of the specimen are arranged in one direction, and a reagent rack in which reagent bottles are stored, in which the reagent rack includes a lid opening unit for opening a lid corresponding to an upward opening of the reagent vessel along an arrangement direction of the reagent vessels, and a lid fixing unit for fixing the lid to the outside of a path in which the reagent dispensing unit is inserted into the opening.

  • Patent number: 12095090
    Abstract: A binder composition for an electrochemical device contains a polymer A and water. In the polymer A of the binder composition for an electrochemical device, the content of an amide group-containing monomer unit is not less than 10 mass % and not more than 90 mass %, and the content of an epoxy group-containing monomer unit is not less than 0.1 mass % and not more than 50 mass %.

  • Patent number: 12066448
    Abstract: An inspection result of a specimen inspection automation system can be reported within a prescribed time, even if a large number of urgent specimens have been input. An instruction reception unit receives turn around time (TAT) information and a discharge instruction. The necessity of discharging a specimen for which the instruction was issued with the discharge instruction is determined and a discharge instruction unit creates a discharge destination and a conveyance route to the discharge destination for the specimen. A discharge mechanism discharges the specimen for which the instruction was issued. Even for a specimen which is caused to wait for processing due to the occurrence of specimen congestion and for which there is a risk of an inspection result reporting delay, an inspection result can be reported within a prescribed time by switching from automatic processing by the system to manual processing by an operator.

  • Publication number: 20240192181
    Abstract: A chromatograph allows easy replacement of a separation column while preventing an operator from contacting with a configuration related to the separation column. A column cartridge accommodates the separation column and is detachably provided in a predetermined column installation position. An upstream pipe is detachably provided on the column cartridge in a state of being installed at the column installation position, and supplies a mobile phase to the separation column of the column cartridge. A downstream pipe is detachably provided on the column cartridge in a state of being installed at the column installation position, and delivers the mobile phase that has passed through the separation column of the column cartridge. A cover integrally covers the column installation position, the upstream pipe, and the downstream pipe and has an insertion hole that allows the column cartridge to be installed from the outer side of the cover.

  • Patent number: 11978903
    Abstract: Provided is a binder composition for a secondary battery with which a slurry composition for a secondary battery having low foaming can be produced, and that can improve handleability of a functional layer or electrode layer formed using the produced slurry composition for a secondary battery. The binder composition for a secondary battery contains a polymer A and a solvent. The polymer A includes an amide group-containing monomer unit and a carboxylic acid ester-containing monomer unit including an alkyl chain having a carbon number of not less than 2 and not more than 9. Content of the carboxylic acid ester-containing monomer unit in the polymer A is not less than 12 mass % and not more than 28 mass %.

  • Patent number: 11955641
    Abstract: A binder composition for a non-aqueous secondary battery contains water-soluble macromolecules, water, and a particulate polymer formed of a polymer that includes a block region formed of an aromatic vinyl monomer unit. Surface acid content A of the particulate polymer is 0.05 mmol/g or more, acid content B in an aqueous phase of the binder composition per 1 g of the particulate polymer is not less than 0.03 mmol/g and not more than 0.80 mmol/g, and a ratio (A/B) of the surface acid content A of the particulate polymer and the acid content B in the aqueous phase of the binder composition is not less than 0.5 and not more than 5.0.

  • Publication number: 20240060941
    Abstract: A technique for replacing a separation column includes: a driving device supporting a first pipe along a first direction; a fixing member that fixes a second pipe to be opposed to the first pipe along the first direction; a column case between the first pipe and the second pipe, having a first and second holes communicating with the first and second pipes, respectively; and an interlocking mechanism that moves the column case in the first direction in conjunction with movement of the first pipe. The column case allows a column cartridge retaining a separation column to be connected and disconnected. The driving device moves the first pipe and the interlocking mechanism such that two states are reversibly taken; a closed state in which the separation column is between the first and second pipes and an open state in which the first and second pipes are positioned outside the column case.
