  • Publication number: 20150192530
    Abstract: A nuclear material within a container is to be detected. Included are: a neutron source for generating neutrons emitted toward the container; a detection section capable of detecting neutrons including primary neutrons emitted from the neutron source and secondary neutrons generated through a nuclear fission reaction of the nuclear material; and a processing section for performing a reactor noise analysis process based on data obtained through detecting of neutrons by the detection section. The neutron source generates neutrons in a pulsatile manner. The processing section performs the reactor noise analysis process based on data obtained by excluding, from time series data obtained through detecting of neutrons by the detection section, data of a time range including a generation time of the neutrons generated by the neutron source in the pulsatile manner.

  • Publication number: 20120199142
    Abstract: There is provided a mask that includes a mask body and two strings. The two strings hold the mask body at a predetermined position on the face of a wearer by being caught by both ears or the head of the wearer. Folded portions, which are adapted so as to be capable of rising and falling on the surface of the mask body coming into contact with the face of the wearer, are formed on both sides of the mask body.

  • Publication number: 20120065633
    Abstract: The stirring efficiency of a heating liquid which is supplied to the balloon of a balloon-equipped ablation catheter is increased to quickly uniformize the surface temperature of the balloon, and air is prevented from remaining in the balloon-equipped ablation catheter to enhance the safety of treatment which uses the balloon-equipped ablation catheter. A shaft for a balloon-equipped ablation catheter, consisting of a single pipe, wherein the shaft has two lumens which communicate from the distal end to the proximal end of the shaft, a first lumen being a guide wire passage lumen which is provided in order to allow a guide wire to pass therethrough, the second lumen being a liquid supply lumen which is provided in order to supply liquid to the inside of the balloon of the balloon-equipped ablation catheter.
