  • Patent number: 7606371
    Abstract: A two-way actively stabilized QKD system that utilizes control signals and quantum signals is disclosed. Because the quantum signals do not traverse the same optical path through the system, signal collisions in the phase modulator are avoided. This allows the system to have a higher transmission rate than a two-way system in which the quantum signals traverse the same optical path. Also, the active stabilization process, which is based on maintaining a fixed relationship between an intensity ratio of interfered control signals, is greatly simplified by having the interferometer loops located all in one QKD station.

  • Patent number: 6778765
    Abstract: The present invention provides a camera which restrains a photosensitized material from being unstably discharged, while allowing a reduction in diameter of a pair of rollers that feed the photosensitized material out of the camera as well as a transport apparatus which restrains a transported material from being unstably discharged, while allowing a reduction in diameter of a pair of rollers that feed the transported material out of the camera. According to the present invention, an increase in interval between each roller gear fixed to a corresponding one of a pair of rollers and a corresponding one of two roller driving gears meshing with the respective roller gears is suppressed compared to an increase in interval between the roller gears, fixed to the respective rollers.

  • Patent number: 6625395
    Abstract: In a digital instant camera, a fixed exposure head emits a printing light to an instant film contained in a film pack, and a spreading roller performs a developing process. While the instant film is conveyed by the spreading roller toward the outside of the camera, the exposure head emits the printing light in synchronism with the conveyance of the instant film. A conveyance speed of the instant film is suddenly increased at the moment that a developer pod provided on the instant film is broken by the spreading roller. A brake roller, however, prevents the conveyance speed from suddenly increasing. In virtue of the brake roller, the printing light may be surely emitted to the instant film.

  • Patent number: 6509950
    Abstract: A preexposure apparatus comprises a film supply station ST1 for arranging a film cartridge 14 containing a film 12 accommodated therein, a film-drawing station-ST3 for automatically drawing the film 12 over its entire length, an exposure station ST5 for exposing a predetermined portion of the drawn film 12 with an image by the aid of an exposure section 32, a winding station ST6 for automatically rewinding the film 12 after the exposure into the film cartridge 14, and a withdrawing station ST8 for withdrawing the film cartridge 14. Accordingly, the predetermined portion of the film can be preexposed with a desired image automatically and efficiently.
