Abstract: A manipulator arm includes a parallel link, an actuator, and first and second covers. The parallel link includes first and second end members spaced apart from each other, a first link attached to the first end member at a first position and to the second end member at a second position, and a second link attached to the first end member at a first position and attached to the second end member at a second position, the first link being parallel to the second link. The actuator is attached to the first end member at a first actuator position and attached to the second end member at a second actuator position. The first cover is on the first link and covers at least the actuator, and the second cover is on the first link and covers at least the second link and the actuator.

Abstract: A drape for a surgery assist apparatus includes a cover that covers a portion of the surgery assist apparatus, and a hood that is attachable to a holder of the surgery assist apparatus that holds a surgical instrument, The hood includes a penetration hole and a closure sheet that closes the penetration hole. When a separator of the surgery assist apparatus is attached to the holder, the closure sheet is broken, and the penetration hole is closed by the separator.

Abstract: A surgical robot includes a main body portion, an arm provided on the main body portion to hold an endoscope, an attachment member that detachably attached the main body portion to a table portion of a bed, and a vertical drive mechanism that allows the main body portion to move along a first direction perpendicular to the table portion. The arm is pneumatically driven.

Abstract: A surgical system includes a gripping robot that holds a treatment tool, a storage, and a controller. The storage stores relationship information of a relationship between condition information of a surgery and a position of the gripping robot. The controller sets, based on the relationship information from the storage, an initial position of the gripping robot, and generates a control signal to control the gripping robot to move to the initial position and outputs the control signal to the gripping robot.

Abstract: A surgical robot includes an operating section that receives a pressure from a gas, a pressure generating device that generates the pressure, a pressure detector that detects a pressure supplied from the pressure generating device to the operating section, and a control device configured to implement an operation diagnosis device that makes a determination, using the pressure detected by the pressure detector, whether the operating section is operable, and that notifies a result of the determination.

Abstract: An object is to provide a camera head adaptor that allows an endoscope to be detachably attached with a simple operation and that can prevent stress on electrical wirings, optical cables, etc. in an insertion portion due to a camera head being held. The camera head adaptor for holding an endoscope having a camera head comprises: a holding portion that holds the camera head of the endoscope in a detachable manner; a connecting portion that extends along an observation optical axis of the camera head and can be attached to a support structure; and a coupling portion that couples the holding portion and the connecting portion.

Abstract: An aluminum alloy for heat exchangers, the alloy, comprising a base compostion selected from a group consisting of Al-Mg-Si composition containing 0.1 to 0.8 wt % of Mg, 0.2 to 1.0 wt % of Si and 0.3 to 1.5 wt % of Mn; pure-Al composition; Al-Mg composition containing 0.05 to 1.0 wt % of Mg; and a Al-Zn composition containing 0.05 to 2.0 wt % of Zn. The alloy further comprises 0.01 to 0.3 wt % of Fe and/or 0.01 to 0.3 wt % of Ni, wherein the balance are aluminum of purity of 99.9% or higher and unavoidable impurities contained therein, and content of Cu as one of the impurities is controlled to be 0.05 wt % or less.

Abstract: A method of manufacturing a cathode for magnetron comprises a cathode sleeve formed as a hollow cylinder, a heater inside the sleeve, two end shields formed around the sleeve at a prescribed interval and an electron emitting material applied around the sleeve between both end-shields, wherein a plurality of isolated projections are almost regularly and intergraly formed around the sleeve between the end-shields, and the above electron emitting material is applied onto the cathode sleeve to fill gaps among the plural projections.According to the method of manufacturing a cathode of the present invention, the efficiency of electron emission and electric conductivity are not lowered, whereby the stable operation can be realized for a long term.
