摘要： A centrifugal compressor includes an impeller and a diffuser arranged around the outer periphery of the impeller and including a pair of annular, spaced diffuser plates defining a diffuser channel therebetween. A plurality of guide vanes are provided on at least one of the pair of diffuser plates to guide a low flow angle portion of a fluid flow introduced into the diffuser channel from the outlet of the impeller. The guide vanes each extend from the inlet of the diffuser channel to a position which does not exceed about one half the distance between the inlet and the outlet of the diffuser channel and have a height which is less than one half the spacing between the pair of diffuser plates.

摘要： In an impeller of a centrifugal blower of the backward type having a relatively large blade inlet width as contrasted with the diameter of the impeller, blades are each shaped, as seen from the axial direction of a rotary shaft, in a concave curve with respect of rotation of the impeller, each of the blades has a larger inlet diameter on the shroud plate side than on the hub plate side, and each of the blades has a leading edge shaped, in a meridional plane, in a smooth convex curve directed radially inwardly of the impeller. By these structural features, it is possible to bring the inlet blade angle into agreement with the inlet relative flow angle at each point of the leading edge of each blade and to reduce the rate of a reduction in the velocity of flow on the shroud plate side. Thus separation of the flow from blade surfaces and production of noise caused thereby can be prevented, and a sufficiently large blade area to achieve high efficiency can be obtained, so that a loss of load on the blade surfaces can be avoided and a higher pressure coefficient than in conventional impellers can be obtained. Each blade can be developed in a plane, and its leading edge can be in the form of a circular arc centered on a side edge of the blade either on the hub plate side or on the shroud plate side. Thus the impeller is hydrodynamically advantageous and easy to fabricate.

摘要： A strain sensor improved in detection accuracy without variation of bending stresses applied to the strain detecting element. The sensor substrate has a first fixing hole at one end and a second fixing hole at the other end, a detecting hole at the center, and at least one strain detecting element on the upper surface or lower surface thereof. The first fixing member is press-fitted into the first fixing hole. The second fixing member is press-fitted into the second fixing hole. The detecting member is press-fitted into the detecting hole. Further, when an external force is applied to the detecting member, strain generated due to the positional shift of the detecting member is detected by the strain detecting element with respect to the first fixing member and the second fixing member.
