Abstract: A method for evaluating a quartz glass crucible constituted by an outer layer formed of an opaque quartz glass containing a bubble, and an inner layer formed of a transparent quartz glass. The method includes steps of preparing a quartz glass crucible to be evaluated, irradiating the quartz glass crucible to be evaluated with ultraviolet rays as an excitation light, detecting a blue fluorescence emitted from the quartz glass crucible irradiated with the ultraviolet rays, and evaluating a state of oxygen deficiency defects in the outer layer of the quartz glass crucible on the basis of existence or non-existence of the blue fluorescence. The method allows hydrogen doping and water vapor introduction to attain nondestructive and easy evaluation on the state of the oxygen deficiency defects generated in the quartz glass crucible.

The mask body part has an inner side face at least a portion of which faces the face of the subject, an outer side face positioned on an opposite side to the inner side face, and a plurality of protrusion portions provided on the outer side face. The cushion member has a plurality of engagement portions each of which is engaged with a corresponding one of the plurality of protrusion portions.

Abstract: An airway adapter forms a part of a breathing circuit that is connected to a test subject. A first cylindrical portion forms a male terminal that is fitted into a female member forming another part of the breathing circuit. A second cylindrical portion forms a female terminal that compartmentalizes a fitting portion into which a male member forming another part of the breathing circuit is fitted. An airway forming portion is disposed in an internal space compartmentalized by the first cylindrical portion, and forms an airway communicating with the fitting portion. A first sealing member is disposed on an outer circumferential surface of the first cylindrical portion and has higher flexibility than the first cylindrical portion.
