  • Patent number: 11939887
    Abstract: A turbocharger includes a first housing configured to house a turbine impeller, a second housing configured to rotatably support a rotating shaft to which the turbine impeller is fixed, and a variable capacity mechanism configured to surround the turbine impeller and to guide a fluid to the turbine impeller. The variable capacity mechanism has a nozzle ring that faces the second housing. A first pin and a second pin extend between the second housing and the nozzle ring and are attached to one of the second housing and the nozzle ring. The other of the second housing and the nozzle ring is provided with a first guide in which an end portion of the first pin is disposed and a second guide in which an end portion of the second pin is disposed.

  • Patent number: 6986848
    Abstract: A method for purifying nucleic acids or proteins comprising a plurality of piston pumps; and a plurality of nozzles capable of having a plurality of disposable tips which are automatically attachable/detachable. The apparatus includes a mechanism for mixing a liquid mixture of each sample and a reagent in a plurality of sections of a container by sucking up a plurality of the mixtures into tips, followed by discharging the mixtures in the sections simultaneously. The apparatus also includes a mechanism for dispensing a desired amount of a reagent to be used subsequently into the same number of sections of a different container as samples, while the mixing is in progress.

  • Patent number: 6455684
    Abstract: A method for analyzing an objective substance, comprising reacting a labeled probe with an objective substance on a biological sample, said probe comprising a label substance of the formula (I): wherein A1 is an aromatic group, R1 is a hydrogen or —COCH2COCnF2n+1 and n is an integer of 1-6, which is bonded to a probe selected from the group consisting of nucleic acid, nucleic acid binding protein, low molecular ligand and receptor for ligand (except antibody) to give a fluorescent complex, reacting the complex with an objective substance on a biological sample and assaying fluorescence of the resultant fluorescent complex, a labeled nucleic acid probe and a labeled nucleotide. According to the method of the present invention, defects such as hindrance of fluorescence due to contaminant substance, low sensitivity and the like can be resolved, thereby enabling analysis on a tissue.
