    摘要： The invention is intended to reduce the profile loss. For that purpose, according to the invention, a plurality of turbine blades are arranged in the circumferential direction of a turbine driven by a working fluid. Each of the turbine blade is formed such that the curvature of a blade suction surface, which is defined by the reciprocal of the radius of curvature of a blade surface on the blade suction surface side, is decreased monotonously from a blade leading edge defined as the upstream-most point of the blade in the axial direction toward a blade trailing edge defined as the downstream-most point of the blade in the axial direction.

    摘要： Disclosed is a highly efficient turbine nozzle blade that reduces the number of blades in an axial-flow turbine while reducing secondary-flow loss. In the nozzle blade, when a differential pressure between a pressure side and a suction side of each blade, at the same axial chord position of the blade, is defined as a load of the blade, and a ratio between axial chord length “Cx” of the blade and an axial distance “xp” from a leading edge of the blade at a maximum load position that maximizes the blade load is defined as a maximum load relative position, Cx is greater at a hub and tip than at an intermediate vertical portion, and simultaneously a maximum load relative position at the hub and tip is set to be nearer to a trailing edge thereof than a maximum load relative position of the intermediate vertical portion of the blade.

    摘要： An electrode and a lead wire therefor used with a device for measuring the electrical signals emanating from a living body, such as a cardiograph or electroencephalograph employed for examination and diagnostic purposes. The electrode consists of two layers of finely divided electrically conductive material, that are printed in laminated fashion on the opposite surfaces of an insulating film. The lead wire comprises plural laminated layers of finely divided electrically conductive material on the opposite sides of an insulating film, the laminated layers being interspersed with or encased by carbon layers and insulating layers. Since X-rays penetrate the electrode and the lead wire, an X-ray photograph may be taken during visual inspection of the biosignals without the image of the electrode and the lead wire appearing on the film to hinder diagnosis.
