  • Patent number: 9655987
    Abstract: The sterilization system includes a plurality of spaces to be sterilized by a sterilization process; a gas supply source generating nitrogen dioxide gas; a piping system and a valve device; a nitrogen dioxide gas sensor; and a control device. The control device performs a gas filling process in which each of the plurality of spaces to be sterilized is connected to the gas supply source one by one for a first predetermined length of time and successively filled with the nitrogen dioxide gas by controlling the valve device, and when the concentration of the nitrogen dioxide gas in a space to be sterilized that is being filled with gas is detected by the sensor to have reached a predetermined level, the control device performs control such that the subsequent gas filling process is performed with this space to be sterilized being excluded from the gas filling process.

  • Patent number: 8968651
    Abstract: By focusing on the fact that nitrogen dioxide exhibits an increased sterilizing effect among other sterilant gases including nitrogen oxide, the present invention is made to provide a sterilization method which may be suitably used for sterilizing items to be sterilized such as medical instruments which require increased reliability by using a high concentration NO2 gas of 5,000 ppm or above, for example. An inside of a sterilizing chamber containing an item to be sterilized is humidified, and a concentration of NO2 in the sterilizing chamber is made to be from 9 to 100 mg/L by filling a high concentration NO2 gas.

  • Publication number: 20090088496
    Abstract: A rubber-filler composite exhibiting low heat build-up, fatigue resistance and heat aging resistance equal to those of a concentrated natural rubber latex, despite using a field latex of a natural rubber and omitting a concentration step is disclosed. The rubber-filler composite is obtained by jetting a field latex of a natural rubber in a form of a high-speed flow having a flow rate of 500 m/sec or more into a mixing chamber while supplying a filler slurry containing a filler to the mixing chamber, thereby separating and removing protein in the field latex from a rubber component and at the same time, mixing the field latex and the filler slurry.
