摘要:
Observation samples in a sample solution are held due to absorption or the like on a rear face of a first X-ray transmission film. In a mirror body, while an X-ray emission film and X-ray transmission films are bent to be convex outward due to a pressure difference, an X-ray transmission film is bent to be convex toward the X-ray transmission film side due to gas expansion in a second cavity part. This bending results in widening of a gap between the first and second X-ray transmission films in their center part more compared with a gap between their end parts. However, there is almost no change between the X-ray transmission films.

摘要:
A blood pressure information measurement device includes an air bladder wrapped around a central side of a measurement portion for pulse wave measurement and an air bladder wrapped at a peripheral side for blood pressure measurement. The air bladder for blood pressure measurement is increased to a pressure higher than a systolic blood pressure, and a blood pressure is measured. An internal pressure of the air bladder is maintained, a pulse wave is measured in avascularized state, and a feature point needed for calculating an index for determining an arteriosclerosis degree is extracted from the pulse wave. When the feature point is not extracted from the pulse wave, the internal pressure of the air bladder for blood pressure measurement is reduced to a pressure lower than the systolic blood pressure, a pulse wave in non-avascularized state is measured, and a feature point is extracted from the pulse wave.
摘要:
A first thermistor 8 and a second thermistor 9 are arranged forwardly and rearwardly of a thermopile sensor 5. A thermopile chip 55 is arranged and interposed between the first thermistor 8 and an integrated thermistor 57. A sensor cover is mounted in contact with front and side portions of a can portion 59 of a thermopile casing 56. A temperature or a radiant quantity of infrared rays on the front portion of the can portion is estimated from a temperature change of the integrated thermistor per second.
