  • Patent number: 9033623
    Abstract: At a contact step in a tool radius adjusting method, a reference portion of a movable body provided radially movably on a housing of a boring tool and a position adjusting reference member fixed on a machine tool are brought into contact by sliding the movable body relative to the housing so that the position of a cutting blade comes to a predetermined position in a direction to go away from a rotational axis. Then, at an adjusting step, the position of the cutting blade relative to the rotational axis is adjusted by changing the relative position between a tool spindle holding the boring tool and the position adjusting reference member in a direction to come close to each other by drive mechanisms of the machine tool used for positioning a spindle head with the tool spindle relative to a workpiece in machining the workpiece with the cutting blade.

  • Patent number: 8998785
    Abstract: A tool radius adjusting device executes an operation for adjusting the tool radius of a boring holder in parallel with execution of a machining program for executing an operation of a spindle head and an operation of a tool changer. A carrier control unit determines whether the tool changer is executing a tool changing process. When the tool changing process is not being executed, the carrier control unit allows the carrier device to execute an operation for picking the boring holder out from the tool magazine and an operation for returning the boring holder, of which the tool radius has been adjusted, to the tool magazine.

  • Patent number: 8881354
    Abstract: A boring holder in a tool radius adjusting system is provided with a cutting blade and fine and coarse motion adjusting mechanisms each capable of adjusting the position of the cutting blade relative to a rotational axis of the boring holder. The tool radius adjusting system is provided with a tool radius measuring device for measuring the tool radius of the boring holder and a controller configured to calculate a compensation amount based on a tool radius measured by the tool radius measuring device and a target tool radius and to operate the fine and coarse motion adjusting mechanisms based on the compensation amount so that the tool radius is brought into agreement with the target tool radius.

  • Publication number: 20090155417
    Abstract: To promote the digestion of an animal to thereby elevate the feed efficiency or prevent or ameliorate intestinal infections such as inflammatory intestinal injury of the animal, a combination of at least one fungus selected from Aspergillus sojae, Aspergillus tamarii, Aspergillus foetidus, Aspergillus niger, and Aspergillus oryzae with an acidic enzyme produced by the fungus is administered to the animal.

  • Patent number: 6010903
    Abstract: Disclosed is a monoclonal antibody which specifically reacts with active human ceruloplasmin as well as a method for diagnosing Wilson's disease using the same. The monoclonal antibody of the present invention specifically reacts with active human ceruloplasmin, it neutralizes the peroxidase activity of the active human ceruloplasmin upon binding thereto, and it does not specifically react with inactive human ceruloplasmin.

  • Patent number: 5869268
    Abstract: A method for producing a human lymphocyte producing an antibody specific to a desired antigen, a method for producing a monoclonal antibody, as well as monoclonal antibodies produced by the method, are described. The present invention provides a method for producing a human lymphocyte producing an antibody comprising, in the order mentioned, the steps of: transplanting human lymphocytes into an immunodeficient animal so that the human lymphocytes take in the animal body; immunizing the animal with a desired antigen so as to generate human lymphocytes producing an antibody specific to the antigen; and recovering the human lymphocytes producing the antibody from the animal.
