摘要:
A seal structure sealing a fitted part between the guide surface of a bearing part and a shaft part to prevent a fluid from flowing in a direction from a high-pressure fluid side to a low-pressure fluid side. The seal structure comprises a seal ring storage part having a radial contact surface surrounding the shaft part which is formed on the high-pressure fluid side of the bearing part and a seal ring disposed in the seal ring storage part, allowing its side surface facing the contact surface to come into contact with the contact surface, and allowing its inner peripheral surface to be fitted to the outer peripheral surface of the shaft part. The seal ring is formed in such a relative dimension that, even if elastically deformed by the pressure of the sealed fluid, the elastically deformed expanded portion thereof is not brought into contact with the peripheral surface of the seal ring storage part.

A radiation detecting apparatus having: a substrate; a phosphor layer which is formed on a principal plane of the substrate and converts a wavelength of a radiation; and a phosphor protective member including a phosphor protective layer which covers the phosphor layer and is adhered to the substrate, wherein the phosphor protective layer is made of a hot melt resin and an upper surface and a side surface of the phosphor layer and at least a part of at least one side surface of the substrate are covered with the phosphor protective layer. Thus, a moisture-proofing effect for penetration of the moisture from an interface between the phosphor layer and the substrate on the side surface side of the substrate can be improved. Further, by using the hot melt resin for the phosphor protective layer, simplification of manufacturing steps, remarkable reduction in the number of working steps, and remarkable reduction in costs of a product can be accomplished.
摘要:
A scintillator panel having a wavelength conversion member has some problems: lowered durability to be caused by an area not covered with a protective layer around a projection formed on the wavelength conversion member surface; lowered resolution response and CTF caused by an irregularity of the film thicknesses of wavelength conversion members and a variation in gaps between wavelength conversion members and sensor panels; and breakage of the sensor panel by projections when a radiation detector is formed by bonding the scintillator panel and sensor panel. At least one of these problems can be solved by a scintillator panel having projections on the wavelength conversion member surface whose sizes are reduced, and by a radiation detector having such a scintillator panel and a sensor panel bonded together.

Electrochemical corrosion of a reflective layer provided in a scintillator panel is prevented. The scintillator panel includes a conductive base member for supporting a wavelength converter layer and a reflective layer for emitting light converted by a phosphor layer to the outside, in which an insulating layer is formed between the conductive base member and the reflective layer. Alternatively, the above problem is solved by a scintillator panel in which the full circumference including the base member surface side of the reflective layer, the wavelength converter layer side of the reflective layer, and end surfaces of the reflective layer is covered with an insulating layer or a protective film for the reflective layer and a radiation imaging device using such a scintillator panel.
