摘要： A blood delivery port (18) is inclined upward so that a perpendicular line (X) passing the center (O &cir& _) of a centrifugal pump body (12) is positioned between two straight lines ( alpha , beta ) which connect together two circumferential joint points (A, B) in a joint portion between the blood delivery port (18) and a centrifugal chamber (15) and the centre (O &cir& _), and the centrifugal pump body (12) is supported on a driving unit (13) with a blood take-in port (17) inclined upward at an angle larger than that between an inner circumferential surface of the centrifugal chamber (15) and the axis thereof. After the centrifugal chamber has been filled with a liquid, the driving of a rotary body is done in a low-speed mode, a stopping mode and a high-speed mode in the mentioned order. According to the present invention, the stagnation of bubbles in the centrifugal chamber (15) in the centrifugal pump body (12) at the time of starting the circulation of blood to a circuit such as a pump-oxygenator can be prevented reliably.

摘要： Provided is a piston ring with a sprayed coating which exhibits excellent wear resistance and scuff resistance and makes little attack against a mating member. Specifically provided is a piston ring which has, on the sliding surface, a sprayed coating formed by thermally spraying a mixed powder comprising an Mo powder, an Ni-base self-fluxing alloy powder, and a Cu or Cu-alloy powder as the essential components. The sprayed coating comprises, as the essential components, 50 to 80mass% of Mo, 1 to 12mass% of Cu or a Cu alloy, with the balance being an Ni-base self-fluxing alloy, and the area fraction of the Cu or Cu-alloy phase appearing on the sliding surface of the sprayed coating falls with the range of 0.5 to 15%.
摘要翻译：本发明提供一种具有喷涂涂层的活塞环，其具有优异的耐磨性和抗划伤性，并且对配合构件的冲击小。具体而言，提供一种活塞环，其在滑动面上具有对含有Mo粉末，Ni基自熔合金粉末和Cu或Cu合金粉末的混合粉末进行热喷镀而形成的喷镀膜组件。该喷涂层包含作为基本组分的50-80质量％的Mo，1-12质量％的Cu或Cu合金，余量为Ni基自熔合金，并且Cu或Cu的面积分数出现在喷涂涂层的滑动表面上的合金相落在0.5至15％的范围内。
