Abstract: A robot system includes a robot and a motion control unit. The robot includes a bottom, a swiveling base, first to third arms. A bottom side of the first arm is supported on the swiveling base swivelably around a horizontal-direction second axis. A bottom side of the redundant arm is supported on a leading side of the first arm swivelably around an axis parallel to the second axis. A bottom side of the second arm is supported on a leading side of the redundant arm swivelably around a third axis parallel to the second axis. A bottom side of the third arm is supported on a leading side of the second arm rotatably around a fourth axis perpendicular to the third axis. The motion control unit activates the redundant arm so that a control point provided on the fourth axis linearly moves while maintaining a direction of the fourth axis.

Abstract: A medical treatment apparatus includes: a pair of holding members, each including a grasping surface configured to grasp a joining target site in living tissue; an energy application mechanism that is provided in at least one of the pair of holding members, the energy application mechanism being configured to apply joining energy and vibration energy to the joining target site through the grasping surface; and a control device configured to sense whether joining at the joining target site is completed by application of the joining energy to the joining target site, and control the energy application mechanism after the joining at the joining target site is completed to apply the vibration energy to the joining target site.

Abstract: A medical treatment device includes a pair of holding members configured to grasp a target part to be connected and dissected in a body tissue. At least one holding member of the pair of holding members includes an energy application portion having a treatment surface configured to contact the target part when the target part is grasped by the pair of holding members to apply energy to the target part. The treatment surface includes a high-output area configured to apply energy to the target part at a first output value for dissecting at least the target part, and a low-output area configured to apply energy to the target part at a second output value smaller than the first output value. The high-output area and the low-output area are provided continuously to each other.

Abstract: A medical treatment apparatus includes a first holding member, and a second holding member configured to move relative to the first holding member and hold a living tissue between the first holding member and the second holding member. On a cross section including a point where the first and second holding member are in contact with the living tissue, a point on the first holding member that is nearest to the second holding member is defined as a first point and a point on the second holding member that is nearest to the first holding member is defined as a second point. The first and second holding member have shapes in which an extended line of a trace of the second point moving relative to the first holding member does not pass through the first point.

Abstract: A bone prosthesis material that promotes calcium ion elution while retaining its effect on osteoclasts so that its binding to a bone can be achieved at an early stage. The bone prosthesis material that is composed of a plurality of ?-tricalcium phosphate (?-TCP) phases containing monovalent cations in solid solution at different concentrations. Being a composite phase of ?-TCP phases containing monovalent cations in solid solution at different concentrations, the bone prosthesis material promotes calcium ion elution while retaining its effect on osteoclasts, and thus enables its binding to a bone at an early stage.

Abstract: A robot control system according to an aspect of an embodiment includes a plurality of robots, at least one external axis, and converters. The robots perform axis behaviors. The external axes are a movable axis shared by the robots and are mutually connected to the robots. Each of the converters assumes a virtual robot formed by connecting all the external axes to the one robot and converts acquisition values on positions of the robot and the external axes acquired for the virtual robot into conversion values indicating absolute positions in a predetermined normal coordinate system.

Abstract: A robot system is provided, which includes a conveying device for conveying a workpiece, a robot for performing a predetermined task to the workpiece being conveyed by the conveying device, a drive source for driving the conveying device; and a control device for controlling operations of the robot and the drive source. The control device includes a drive source instruction value calculation module for calculating a drive source instruction value indicative of an instruction to operate the drive source, and a robot instruction value calculation module or calculating a robot instruction value indicative of an instruction to operate the robot based on the drive source instruction value calculated by the drive source instruction value calculation module.

Abstract: The present invention discloses a cell culturing system that cultures predetermined cells collected from a patient and supplies cultured cells to the original patient, which together with enabling correlations between the cultured cells and the supplier of the cells to be managed accurately and easily at all times, allows cultured cells and patients to be collated rapidly.

Abstract: A reverse flow preventing device arranged in a flow path of fluid formed by a fan and an electronic apparatus equipped with the same. The reverse flow preventing device has a frame, a plurality of support shafts arranged about the center of the frame and mounted on the frame, and a plurality of pivotable plate members supported by the support shafts. The plate members can move between the first position (reverse flow preventing position) in which they lie in a substantially single plane and the second position (normal operating position) in which they move. The support shafts and the plate members are arranged substantially concentrically or radially.

Abstract: An object is to implant a bioprosthesis constituted by infiltrating a scaffold material held inside a container with body fluid, such as bone marrow, into an affected side without separating the body fluid, to reduce the burden placed on a patient, and to improve the ease-of-use.
