  • Patent number: 11327088
    Abstract: A reagent-bottle lid opening mechanism is disclosed, which has a needle for piercing a lid of a reagent bottle to be delivered to a reagent disk, has an aligning mechanism of automatically adjusting a position of the needle with respect to the lid such that a needle body of the needle can stick in the center of the lid, and accurately and repeatedly makes an incision in the center of the lid. As a result, an automatic analyzer is provided that is capable of unsealing the center of the lid of the reagent bottle with accuracy even if the central axis of the needle and the central axis of the lid are offset from each other.

  • Patent number: 11175301
    Abstract: An automatic analyzer includes: a reagent mounting unit 103 in which a plurality of reagent bottles 10 are installed when a reagent bottle 10 is loaded into the automatic analyzer; a reagent conveying mechanism 101 including a gripper mechanism 106; and a reagent mounting mechanism 102 for moving the reagent mounting unit 103 between an installation position at which an operator installs the reagent bottle 10 in the reagent mounting unit 103 and a position at which the gripper mechanism 106 grips the reagent bottle 10. It is thereby possible to achieve saving of a mechanism installation space and reduction of the number of constituent components, automatically carry out an operation from opening of the reagent bottle to loading of the reagent bottle into the reagent disk, and alleviate an operator's burden.

  • Publication number: 20210349052
    Abstract: An electrolyte analyzing device with which an electrical effect does not occur has a housing to which a reference potential is applied and a flow passage which is electrically insulated from the housing. The analyzing device delivers a sample solution to a first electrode, and delivers a reference electrode solution to a second electrode. A reagent vessel placement unit which is electrically connected to the housing, has placed thereon a diluent bottle accommodating a diluent, an internal standard solution bottle accommodating the internal standard solution, and a reference electrode solution bottle accommodating the reference electrode solution. The reagent vessel placement unit includes a suction nozzle comprising an electrical conductor which is joined to the flow passage, and which can be inserted into and removed from each of the diluent, internal standard solution and reference electrode solution bottles. And, an insulator electrically insulates the suction nozzle and the housing.

  • Patent number: 11131682
    Abstract: The automatic analyzer includes a gear pump that supplies cleaning water to reagent probes and sample probes; a cleaning flow path that feeds the cleaning water discharged from the gear pump to the respective probes; a pressure sensor that measures pressure of the cleaning flow path; a return flow path that is disposed in parallel to the gear pump and connects a discharging port side of the gear pump and an aspirating port side thereof; a throttling unit that is disposed in the return flow path and adjusts a flow rate of the cleaning water flowing through the return flow path; and a control unit that changes an opening and closing degree of the throttling unit according to a measurement result of the pressure sensor. Accordingly, it is unnecessary to control driving of a pump used for cleaning a probe while having a low cost and a small mounting size.

  • Publication number: 20210165009
    Abstract: Provided is an electrolyte analyzing device that prevents contamination caused by contacting different reagents by a suction nozzle when reagent replacement is performed. The electrolyte analyzing device includes a nozzle support part 203 coupled to a suction nozzle 6 and movable between a reagent container replacement position and a reagent suction position; a locking mechanism 301 fitted with the nozzle support part 203 moved to the reagent container replacement position and fixes the nozzle support part 203 at the reagent container replacement position; and an unlocking mechanism 302 that releases fitting of the nozzle support part 203 and the locking mechanism 301 in a power-on state. When a reagent container 101 satisfies a predetermined condition, the unlocking mechanism 302 is controlled to release the fitting between the nozzle support part 203 and the locking mechanism 301, so that the nozzle support part 203 moves to the reagent suction position.

  • Patent number: 7465866
    Abstract: An assistive music playing apparatus plays a music piece with musically acceptable notes even when the player inputs musically unacceptable notes. The apparatus provides a chord progression pattern, and comprises a note conversion device. A chord progression pattern defines a series of chords, which are presented one after another in time for a music progression. As the player plays music, inputting potentially unacceptable notes, the inputted notes will be converted to musically acceptable notes with reference to the currently presented chord in the chord progression. The note conversion rules are prepared different for a melody note range, a chord note range and a bass note range. Overlap of converted notes are avoided. Depending on the conditions of the player's note input, i.e.
