Abstract: An optical sheet for display use wherein two or more optical sheets are stacked therein and the optical sheets are joined to one another on one peripheral side of each by a thermoadhesive film is to be provided. Also an optical sheet for display use wherein two or more optical sheets are stacked therein and the optical sheets are joined to one another on two or more peripheral sides of each by a thermoadhesive film is to be provided.

Also, it is free from a problem which derives from protective sheets, resulting in advantages in both cost and quality aspects. Moreover, it is free from a problem which arises when multiple layers of films are stacked.

Abstract: When laser beams with a wavelength of 9.3 ?m or 9.6 ?m are used, a pulse width t (?sec) 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 ?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 B1 and B2. As a result, since the pulse width t is within a range of equal to or larger than 3 ?sec and smaller than 30 ?sec, a high-quality marking pattern with excellent visibility can be formed while improving the productivity of the X-ray film.

Abstract: 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: 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.

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 surface roughness is set in the range of 0.2 ?m to 1.0 ?m.

Abstract: A transfer device in which a material which transmits a laser beam LB is employed as an upper mold, and a photothermal conversion layer is formed thereon. A transfer film, at which a transfer material layer is formed, and a workpiece are superposed and pressured between the upper mold and a lower mold. During this pressuring, the laser beam is irradiated in accordance with a pattern of an organic electroluminescent light-emitting layer that is to be formed on the workpiece. Thus, the photothermal conversion layer is heated and the transfer material layer is softened. As a result, the transfer material layer is cleaved and detached from a temporary support, and a component in the transfer material layer that is to form the organic electroluminescent light-emitting layer is transferred to the workpiece. Accordingly, efficient transfer processing is enabled when a transfer material is transferred to a transfer object by a thermal imaging process.
