A particle beam treatment apparatus including a rotating gantry that revolves and displaces an irradiation port for irradiating a radiation treatment room provided inside of the rotating gantry with a charged particle beam comprises: a gantry body portion forming the rotating gantry; a mounted magnet; a displacement meter or an acceleration meter; and a control mechanism. The mounted magnet is connected to the gantry body portion with an intermediation of a magnet support, and guides the charged particle beam to the irradiation port. The displacement meter or the acceleration meter is provided to the mounted magnet, and measures a displacement or an acceleration of the mounted magnet. The control mechanism controls a position of the mounted magnet in a direction so as to reduce the displacement or the acceleration with at least a single degree of freedom measured by the displacement meter or the acceleration meter.

Particle beam treatment apparatus

An oil pan for an internal combustion engine wherein the oil dropped on a shallow bottom section is rapidly returned into a sump. A plurality of guide ribs are disposed on the downstream side of the shallow bottom section which is located at the downstream side of the oil flow caused by the rotation of a crankshaft of the engine. The guide ribs are formed in an arcuate shape so as to curve toward the sump as they approach a side wall located at the downstream side, by which the oil flow is directed toward the sump. Additionally, a guide plate formed integrally with a baffle plate extends upwardly to guide the flowing oil into the sump.
