  • Patent number: 9460820
    Abstract: A radiation shielding method and a device, and a method of processing a structure, in which a first radiation-shielded region (A1) is provided by disposing a first radiation-shielding device (100) outside a nuclear reactor vessel (41), a neutron flux detector (77) is moved into the radiation-shielded region (A1) through a conduit tube (65) by moving a thimble tube (68) from the nuclear reactor vessel (41), and an inspection/repair work of the nuclear reactor vessel (41) is then performed, so that an amount of radiation delivered to a worker can be easily and sufficiently reduced.

  • Publication number: 20100224508
    Abstract: An ink composition for sensing carbon dioxide gas contains a pH indicator formed using a combination of two or more types of pH indicator components, binder, and solvent and allows easy visual observation of color changes of an indicating portion caused by the concentration of carbon dioxide gas. When the ink composition is applied to a carbon dioxide indicator and package, a pinhole and poor seal of a carbon-dioxide-ambient package are easily found.

  • Patent number: 6810766
    Abstract: A brake pedal apparatus for a vehicle is provided with a pedal bracket having a pivot shaft, a pivot bracket having a pedal shaft, a pedal arm, a slide plate fixed to a body structural member of the vehicle and located between the body structural member and the pedal bracket, an impact absorbing section, and a rotational motion assisting section. The impact absorbing section permits relative movement of the pivot bracket and the body structural member in a longitudinal direction of the vehicle when the pedal bracket encounters an external force directed rearward of the vehicle at a level beyond a predetermined load, in such a manner that the pivot bracket disengages from the slide plate to allow the pivot bracket to rotate about the pivot shaft while rotating the pedal shaft therewith rearwardly downward of the vehicle.

  • Patent number: 6742411
    Abstract: A brake pedal apparatus for an automotive vehicle is disclosed as including a pedal bracket 2, a pivot bracket 3, a slide plate 9 fixedly secured to a vehicular body structural member 41, 52, and an impact absorbing section 10 located between the pedal bracket and the slide plate. During a frontal collision of a vehicle, the impact absorbing section allows the pedal bracket to be contracted and deformed into a position wherein a pedal arm 8 is retracted in a forward direction of the vehicle whereby even when a master vac. is retracted in the forward direction or even when a dash floor panel 40 is deformed into a vehicle compartment with a resultant rearward movement of a push rod 24, a depressing position of the pedal arm remains in a position to avoid a differential feeling touch to be applied to a vehicle driver.
