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.

Sterilization system and gas filling method

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 NOgas 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 NOin the sterilizing chamber is made to be from 9 to 100 mg/L by filling a high concentration NOgas.

Sterilization method

A high concentration NOgas generating system including a circulating path configured by connecting a chamber, a plasma generator, and a circulating means, wherein NOis generated by circulating a gas mixture including nitrogen and oxygen in the circulating path is provided. The high concentration NOgas generating system provides a high concentration NOgenerating system and the high concentration NOgenerating method using the generating system by which NOof high concentration (approximately 500 ppm or above) required for a high level of sterilization process in such as sterilization of medical instruments can be simply and selectively obtained. In addition, since indoor air is used as an ingredient, the management of ingredients is simple and highly safe, and the high concentration of NOcan be simply and selectively prepared on demand.

A plasma generation apparatus is provided which includes: a microwave generation portion which generates a microwave; a gas supply portion which supplies a gas to be turned into plasma; a plasma generation nozzle which includes a reception member receiving the microwave, and turns the gas into plasma based on the energy of the received microwave and emits the plasma gas; and a photo-detection unit which detects light emitted by the plasma gas and generates electrical information.

Plasma generation apparatus and work processing apparatus

An image exposing apparatus forms an image on photosensitive material by the technique of exposing and forming an image through direct modulation of a semiconductor laser device. The exposing apparatus includes a beam scanning unit for scanning a beam emitted from a semiconductor laser device to photosensitive material, a laser driving unit for driving the semiconductor laser device, the laser driving unit being operable to vary its driving current to the semiconductor laser device in accordance with a received image signal, and a laser output controller operable to measure current-beam output characteristics of the semiconductor laser device over a predetermined current range and then set a correlation between the image signal for the laser driving unit and the driving current for the semiconductor laser device, based on the measurement information.

Image exposing apparatus having a beam scanner

In a photographic printer using a laser scanning unit for exposing a latent image corresponding to an image data on a sensitized surface of a photographic paper, intensities of the laser beams exposing the photographic paper are adjusted corresponding to a variation of an actual sensitivity of the photographic paper and deterioration of a developer with respect to nominal values of them. At least the intensities directly emitted from laser light sources, or values of optical modulation data for modulating the laser beams corresponding to the image data are varied. Alternatively, transmittances of optical elements such as polarizing beam splitters provided on optical paths are varied for adjusting the intensities of the laser beams.

Photographic printer having varied intensities or optical modulation data for laser light sources

An optical scanning device which performs an exposing operation with respect to a photosensitive material such as a printing sheet, etc., by scanning with laser beams in respective colors modulated according to image data is arranged so as to modulate light beams in respective colors projected from respective light sources of a red LD, a green-color SHG laser unit and a blue-color SHG laser unit by AOMs according to image data. Then, the clock frequency control section adjusts an exposure scanning clock for each of the AOM drivers for driving these AOMs individually. It is therefore possible to suppress an aberration in color caused by a shift in light beams in respective colors which are to be projected onto the same target position.
