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 generator is provided which includes: a microwave generation portion which generates a microwave; a wave guide for propagating the microwave; a plurality of plasma generation nozzles which are attached to the wave guide so as to be apart from each other in the direction where the microwave is propagated, receive the microwave, and generate and emit a plasmatic gas based on the energy of this microwave; and a plurality of stabs which correspond to a part or the whole part of the plasma generation nozzles and are each disposed in the wave guide so as to lie in a rear position a predetermined distance apart from each other in the direction where the microwave is propagated.

Plasma generator and work processing apparatus provided with the same

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

A plasma generation apparatus is provided which includes: an apparatus main body which has a microwave generation section which generates a microwave and a plasma generation nozzle which generates and emits a plasma gas based on the energy of the microwave; a microwave detection unit which detects a microwave leaking from the apparatus main body; and a control section which stops the microwave generation section from generating a microwave if the detection unit detects a microwave.

As a negative film having a multiplicity of perforations provided therein at equal intervals is being transferred, its perforations are detected to produce a corresponding pulse signal. The pulse signal is then fed to a controller which in turn calculates the number of clock pulses for each forty pulses of the pulse signal and determines a transfer distance per clock pulse. Meanwhile, the reference transfer distance is obtained from an interval between the perforations multiplied by forty. A difference between the actual transfer distance and the reference transfer distance is calculated and used for controlling the rotating movement of drive rollers.

Transfer apparatus

A photographic film processing apparatus has a data reader for reading magnetic data stored in a row of magnetic recorded tracks on a photographic film. The apparatus determines whether a reading error has occurred during film processing. If no error has occurred, then the film is processed in accordance with the magnetic data from the film. If an error has occurred, then the apparatus determines whether the data is eligible for replacement with reference data. If the erroneous data is eligible, then the film is processed in accordance with the reference data. If the erroneous data is not eligible, then the film is processed in accordance with external substitute data which is entered by an operator. Furthermore, the apparatus produces a maintenance demand signal based on the number of reading errors or the total length of photographic film processed.

Photographic film processing apparatus and method of controlling the same

A photographic printing apparatus includes a reading device for reading image information from a film, and an exposure condition computing device for computing exposure conditions for exposing a photosensitive material based on the image information read by the reading device. The apparatus further includes an image information converter for converting the image information read by the reading device into image information expected to appear on the photosensitive material when the photosensitive material is exposed to the image information on the film under the exposure conditions computed by the exposure condition computing device. The image information converted by the image information converter is displayed on a monitor. The exposure condition computing device receives instructions through a control panel to correct the exposure conditions for the image information displayed on the monitor, or instructions not to correct the exposure conditions. An exposure device exposes the photosensitive material under exposure condition computed by the exposure condition computing device based on correcting instructions inputted through the control panel. The exposure device is operable in parallel with an input from the control panel to the exposure condition computing device, to exposure the photosensitive material to image information for which the exposure conditions have been corrected based on the correcting instructions from the control panel or for which non-correction instructions have been received.
