  • Publication number: 20210093774
    Abstract: A chamber body is provided, as regions where the liquid flows, with: an upper region including an area from the inner surface of the upper wall to the introduction pipe; a lower region connected to the outlet port; and a connection region connecting the upper region and the lower region. The inner circumferential surface of the upper region has a larger diameter than the inner circumferential surface of the lower region. As a result of diameter reduction from the connection portion relative to the upper region to the connection portion relative to the lower region, an inclined surface is formed on the inner circumferential surface of the connection region.

  • Publication number: 20200206407
    Abstract: Microbubbles detached from a blood circuit and a blood purification unit are discharged with the use of a backflow generated at the instant that a roller of a blood pump releases a squeezable tube. In a normal rotation step, a region filled with a priming solution after a priming step is closed by a closing unit, and a rotor of a blood pump is rotated normally until a roller of the blood pump releases a squeezable tube to generate a backflow. After the backflow is generated at the release of the squeezable tube by the roller of the blood pump, bubbles are moved by reversely rotating the rotor while disabling the closing by the closing unit. Thus, the bubbles are discharged through a discharge unit.

  • Patent number: 10486309
    Abstract: Feedback control is carried out on respective servomotors so that detection angles detected by respective input-side encoders become target angles to be obtained when a leading end of a robot has moved to a positioning completion position of a first motion. Subsequently, the position of the leading end of the robot is obtained on the basis of the detection angles detected by the respective output-side encoders. The time from a time point at which the detection angles detected by the input-side encoders are brought to the target angles through the feedback control to a time point at which a vibration width of the calculated position of the leading end of the robot relative to the positioning completion position converges within a convergence range is obtained. The obtained time is set in the stopping duration of the robot.

  • Patent number: 9815202
    Abstract: Semi-closed control or fully closed control is selected as a control system for a joint using a motor configured to drive a joint of a robot arm via a reduction gear, an input-side encoder, and an output-side encoder, the semi-closed control being control in which an output of the input-side encoder is used, the fully closed control being control in which an output of the output-side encoder is used. A test run is performed plural times in which the robot arm is caused to perform a specific operation while semi-closed control is being performed on the joint, and semi-closed control or fully closed control is selected using outputs of the output-side encoder obtained in the test runs or in accordance with the content of a task that the robot arm is to be caused to perform.

  • Publication number: 20160114483
    Abstract: Rotations of respective motors are controlled so that rotational angles of the respective motors become target angles in an operation completion position of a first operation (S1: robot operation step). After the robot operation step, a leading edge position of a robot is obtained based on joint angles detected by respective output side encoders (S5: leading edge position calculation step). A convergence time until an amplitude at the leading edge of the robot with respect to the operation completion position converges within an allowable range is estimated based on a time change of the calculated leading edge position (S6: estimation step). Rotational operations of the respective motors are paused from a time point at which the rotational angles of the respective motors are controlled to be the target angles to a time point at which an elapsed time reaches the estimated convergence time (S3 and S7: pause step).
