Title: Rotary diagonal plate mechanism
Inventor: YAMAGUCHI KAZUAKI
IPC: F02G1/053
Filed: 1989-03-31
Abstract: PURPOSE:To secure equivalent functions to those of conventional ones while reducing a processing cost in a rotary diagonal plate mechanism having piston rod connecting an actuating piston with a guide piston for guiding a diagonal plate by changing the form of a fastening part of a guide piston from a spherical surface into a column. CONSTITUTION:For a drive part of a Stilting engine, a piston 1 is reciprocated by action of a Stirling cycle, an a guide piston 9 is driven through a piston 13. The reciprocation of the guide piston 9 is converted, so an output is transmitted to the external through a main shaft 4. In this case, a rod end 13a of the piston rod 13 is formed like a column, and parallel motion as a necessary function of the rod 13 is achieved by providing a diametric clearance between the column curved wall of the rod end 13a and a rod spacer 14. An axial clearance is provided between the end wall of the rod end 13a and a shoe clearance spacer 12 to achieve an oscillation mechanism.

Abstract: PURPOSE:To improve the optical transfer property without being influenced by the outside, by using a photoconductive body constituted of two kinds of mediums having different refractive indexes, for converging a stimulated phosphorescent light, in an image information reader of a radiant ray. CONSTITUTION:X rays 2 are radiated to an objective to be photographed 1 such as the human body, etc. and an X-ray transmission image is recorded to stimulable phosphor panel 5. Also, a light beam from a light source 6 of a read part is deflected 7, and the stimulable phosphor panel 5 is scanned. The stimulated phosphorescent light generated from its panel 5 is converged by a light converging conduction body 9 and converted to easily handleable wavelength. Light of its wavelength is brought to a photoelectric conversion by a photomultiplier 11, and its electric signal is processed, by which a read image is obtained. In this regard, the light conversion conduction body 9 is formed by a composite constitution by setting its internal core and external clad to a high refractive index and a low refractive index, respectively, and also, mixing a fluorescent substance into the internal core. In such a way, the converging efficiency of the light conversion conduction body 9 becomes large. Accordingly, since the light conversion conduction body is used, the converging efficiency can be improved, and the optical transmission can be executed satisfactorily without being influenced by the outside.
