Abstract:
A clean booth has a conveyor area for carrying recording sheets, and a motor drive area for containing motor and mechanical parts that emit much dust. The conveyor area and the motor drive area are covered respectively, and separated by a frame plate. Moreover, fan filter units blow pressurized clean air into the conveyor area to discharge dust while a ventilation system exhausts air in the motor drive area. There is no airflow from motor drive area to the conveyor area because of the difference in air pressure. The recording sheets in the conveyor area are carried by belt conveyors with artificial suede belts. The artificial suede belt is suitable to be used as a conveyer belt because of low dust emission and sufficient flexibility to prevent flaw or pressure marks on the recording sheets.

An apparatus for stacking a predetermined number of X-ray films has a sheet member holding device disposed above a stacking position for temporarily holding at least a first X-ray film, and an actuating device for displacing the sheet member holding device from the stacking position to drop the X-ray film held by the sheet member holding device into the stacking position. The apparatus is capable of stacking a plurality of X-ray films highly accurately and efficiently in the stacking position while avoiding damage to the X-ray films.

Abstract:
When a film is rewound, light is applied from light-emitting units to the film, and light that has passed through the film is detected by light-detecting units to detect a plurality of inclined defects in the film based on a change in the intensity of the light transmitted through the film. Slits oriented in the direction of the inclined defects are disposed in front of the light-emitting units and the light-detecting units. Detected signals outputted from the light-detecting units are transmitted to a processing device and processed thereby. The processing device processes the signals by approximating a maximum value array of extremal values of the signals in respective reference lengths of the film, with two functions in zones, and identifying a boundary between the zones as a position where a defect disappears.
Abstract:
When laser beams with a wavelength of 9.3 nullm or 9.6 nullm are used, a pulse width t (nullsec) which is a radiation time of the laser beam and an energy density E (kw/cm2) of the laser beam on an X-ray film are set such that they meet requirements based on an area A between line segments A1 and A2. Moreover, when laser beams with a wavelength of a 10-micrometer band, such as 10.6 nullm, is used, the pulse width and the energy density are set such that they meet requirements based on an area B between line segments B1 and B2. As a result, since the pulse width t is within a range of equal to or larger than 3 nullsec and smaller than 30 nullsec, a high-quality marking pattern with excellent visibility can be formed while improving the productivity of the X-ray film.

Abstract:
By irradiating a laser beam onto an X-ray film that includes a support layer having disposed thereon an emulsion layer, the emulsion layer is melted, numerous minute air bubbles are generated in the emulsion layer, and the emulsion layer becomes convex, whereby a visible dot pattern is formed. The irradiation time and wavelength of the laser beam are selected so that separation is not generated between the support layer and the emulsion layer. By defocusing and irradiating the laser beam, the X-ray film may substantially uniformly receives energy of the laser beam. Moreover, an undersurface layer may also be formed, and the laser beam may be irradiated onto the undersurface layer to form a dot pattern on the undersurface layer. A device and a method for forming a marking pattern representing identification information on a rolled photosensitive material and cutting the photosensitive material into sheets are disclosed.

A photosensitive material in which a fog unnecessary for a photosensitive material is not generated when irradiation of a laser beam and a character or a mark is printed by an array of optically distinguishable dot patterns is provided. When the dot patterns are arrayed by M number in column and N number in row and the character or the mark having a size of AnullB is printed, the dot pattern has irregularity of no more than Snull10 nullm, and an almost circular shape of no lower than 100 nullm and not more than the smaller diameter either A/M or B/N, when viewed from the emulsion layer side. A surface roughness is set in the range of 0.2 nullm to 1.0 nullm.
