    摘要： Provided is a radiation monitor and the like capable of appropriately measuring radiation. A radiation monitor (100) includes: radiation detection units (11, 12); optical fibers (13p, 13q) that transmit light generated by a plurality of radiation detection elements (11a, 12a) to merge; a light detection unit (14) that converts the light after merging guided to the light detection unit into an electric pulse; a measurement device (15) that calculates a dose rate of radiation based on a count rate of the electric pulses; and an analysis/display device (16). Housings (11b, 12b) include a housing (11b) made of a first material and another housing (12b) made of a second material.

    摘要： A rotary fluid machine that reduces fluid leakage from a gear pump or gear motor and achieves improvement in responsiveness is provided. The present invention is configured such that force of pressing a side plate toward gears by a seal member provided between the side plate and a case and performing pressure compartment is partly strong, not uniform along the entire length of the seal member. Specifically, for example, a gear pump comprises an assembly including a pair of gears, a side plate sealing a side surface of the gears, and a seal block sealing tooth tips of the gears, a case housing the pump assembly, and a seal member being arranged between the side plate or the seal block and the case and along a notch portion formed in the side plate or the seal block. The seal member is wider at a portion in a position passing through a place with large pressure fluctuations than at other portions.

    摘要： In order to detach substances stably from an inspection object, an adhering substance collecting device includes: ejection openings configured to eject gas; a housing on which the ejection openings are provided; and supporting portions which are installed on a surface of the housing on which the ejection openings are provided, and have a prescribed height. The supporting portions include protruded portions formed on the housing. The supporting portions each have a cuboid shape, and are installed such that a distance therebetween becomes smaller toward a direction of a recovery opening that is configured to collect substances having been detached from an inspection object, from the gas.
