A functional film having a particular organic film and a particular inorganic film is produced. The functional film is consistently produced and exhibits the intended performance. The functional film production method includes forming an organic film on a surface of a substrate, handling the substrate having the organic film formed thereon so that no member comes in contact with an organic film surface in vacuum until formation of an inorganic film, and forming the inorganic film by vacuum deposition on the organic film surface.

Method for producing functional film

The conveying unit conveys a long sheet-like subject in its longitudinal direction. The conveying unit includes a stepped roller which has large-diameter portions spaced apart from each other in a direction perpendicular to a direction of conveyance of the sheet-like subject and having a larger diameter than a remainder of the stepped roller being a small-diameter portion of the stepped roller, the large-diameter portions supporting and conveying the sheet-like subject, a closed space forming subunit between the small-diameter portion of the stepped roller and the sheet-like subject and a gas supply subunit for supplying a gas to the closed space. The vacuum deposition device forms a film on a surface of a long substrate by vacuum deposition. The vacuum deposition device includes a vacuum chamber, a conveying device which includes the conveying unit and a film forming unit.

Conveying unit and vacuum deposition device

The method for producing a functional film includes a step of forming an organic film on a surface of a substrate and a step of forming an inorganic film by vacuum deposition on a surface of the organic film to produce the functional film. Prior to forming the inorganic film, a member contacts the surface of the organic film in a vacuum chamber at portions where the organic film does not exhibit its functions.

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.

In a marking device, by illuminating a laser beam onto an X-ray film which is a light-photosensitive heat-developing photosensitive material, an inner portion of a surface layer is melted, a cavity is formed, and a dot, which projects a surface out in a convex shape, is formed. At this time, an illumination time of the laser beam is controlled in order to control melting of the surface layer. In the marking device, when conveying of an X-ray film is stopped, oscillation of a laser oscillating tube is continued until a predetermined period of time elapses. When stoppage is for a short time, control is carried out such that marking can be started quickly.

Laser marking method

A sorting and conveying line provided at an X-ray film cutting and collection operation includes a defective sheet gate, a collection gate and a sample gate for sorting X-ray film sheets, which have been cut to a predetermined size at a cutting section, while the X-ray film sheets are conveyed. Film detection sensors are disposed at entrance and exit sides of each of the defective sheet gate, the collection gate and the sample gate, and each film detection sensor detects the X-ray film sheet at times when the X-ray film sheet should be conveyed and sorted. Based on the results of detection, a determination is made as to whether or not there is any failure in control on a number of produced X-ray film sheets, and the like, as well as conveyance and sorting operations. This allows smooth and quick handling in the event of a failure.

Method for controlling manufacture of a sheet material

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.

When laser beams with a wavelength of 9.3 &#x3bc;m or 9.6 &#x3bc;m are used, a pulse width t (&#x3bc;sec) which is a radiation time of the laser beam and an energy density E (kw/cm) of the laser beam on an X-ray film are set such that they meet requirements based on an area A between line segments Aand A. Moreover, when laser beams with a wavelength of a 10-micrometer band, such as 10.6 &#x3bc;m, is used, the pulse width and the energy density are set such that they meet requirements based on an area B between line segments Band B. As a result, since the pulse width t is within a range of equal to or larger than 3 &#x3bc;sec and smaller than 30 &#x3bc;sec, a high-quality marking pattern with excellent visibility can be formed while improving the productivity of the X-ray film.

A sheet package producing system for producing a sheet package having a predetermined number of sheets or X-ray films is provided. A cutting/stacking device forms the sheets by cutting continuous sheet at a regular length, and for stacking the sheets in the predetermined number. A covered sheet stack producing device inserts the stacked sheets into a protective cover, to obtain a covered sheet stack. A packaging device packages the covered sheet stack to obtain the sheet package. The cutting/stacking device, the covered sheet stack producing device and the packaging device are connected in series with one another. Those devices are balanced in line capacity balance relative to one another. In a preferred embodiment, the cutting/stacking device includes a supply module for feeding the continuous sheet. A cutter module cuts the continuous sheet to obtain the sheets. A stacker module stacks the sheets in the predetermined number.

Sheet package producing system

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.

Apparatus for and method of inspecting sheet body

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.
