Abstract: Provided is a scroll fluid machine that, by using a crankshaft manufactured by cold forging and a needle bearing, can sufficiently exhibit the performance of a variable circling radius mechanism, can provide a sufficient reliability on a bearing portion of the crankshaft, and can be manufactured inexpensively. For this purpose, in a crankshaft 60 used for a driving force transmission system, a reinforced shaft unit 63 and a circular column-like large diameter unit 61 are formed at an end of a rotating shaft 16, a material is produced by a cold forging process so that an eccentric shaft 62 projects from the circular column-like large diameter unit 61, the circular column-like large diameter unit 61 is rotatably coupled to a housing 11 via a needle bearing 64, and the variable circling radius mechanism is stably operated with rigidity increased by the reinforced shaft unit 63.

Abstract: There is provided a scroll compressor in which reliability and durability is increased by preventing peeling of a coating layer applied to a thrust plate, to maintain a desired level of lubrication for a long period of time. The scroll compressor has a thrust plate, a coating which is applied to a surface of the thrust plate, a housing having a thrust bearing face to which the thrust plate is attached, an orbiting scroll member having a slide face which is supported by the thrust plate and which orbits while sliding, and a peeling prevention part which reduces a sliding pressure acting on an edge portion of the thrust plate from the slide face.

Abstract: A scroll compressor that suffers no decrease in compression performance due to leakage resulting from a twisting assembly error is provided. This scroll compressor includes a fixed scroll and an orbiting scroll, each including a spiral wrap protruding from an end plate and having the same tooth thickness (Tr) and the same base-circle radius (b) defining an involute surface. The fixed scroll and the orbiting scroll are offset from each other by an orbiting radius (?) and mesh such that the respective wraps face each other with a phase shift of 180°. The orbiting scroll revolves/orbits along a circular orbit with the orbiting radius (?) to compress a gas while a rotation-preventing mechanism prevents rotation of the orbiting scroll.

Abstract: There is provided a fluid machine able to secure a sectional area of a passage sufficient for gaseous fluid flow from a suction port to a compression mechanism, while able at the same time to achieve a reduction in size of the outline shape. In a scroll compressor where a scroll compression mechanism is housed within a housing having a funnel shaped, a compression mechanism main body of the scroll compression mechanism is arranged in a wide opening section of a front housing, and a compression mechanism driving section is arranged in a narrow section, a concave section is formed on the outside of a thrust receiving surface which is positioned on a bottom surface of the wide opening section and which supports the compression mechanism.

Abstract: A radiotherapy monitoring apparatus for monitoring a treatment state by irradiation of radiations on a treatment region includes a flat panel detector that detects the radiations transmitted through the treatment region at least in two places, a comparing unit that compares a relative value of the transmitted radiations in the two places with a reference relative value, and control signal generating units that generate, when the relative value exceeds the reference relative value, a control signal for stopping the irradiation of the radiations.

Abstract: A scroll compressor includes an orbiting scroll engaged with a front case by pins and rings or ring holes to prevent rotation of the orbiting scroll. The rings or the ring holes have such an inside diameter that an orbiting radius defined by the pins and the rings or the ring holes is larger than a theoretical orbiting radius defined by engagement between gear surfaces of a fixed scroll and the orbiting scroll. The pins, the rings, or the ring holes are shifted in such a direction as to relieve twisting of the orbiting scroll relative to the fixed scroll.
