    • A compressed gas storage tank 10 utilizes a rock-bed cavity 11 in which a bentonite slurry is fed into an underground cavity 11 formed in a rock-bed, a forcibly fed compressed gas is stored in the rock-bed cavity in a state in which the compressed gas is loaded with a pressure load of the bentonite slurry from the underside of the compressed gas, the bentonite slurry in the rock-bed cavity 11 is of a dual layer structure consisting of an upper layer composed of a light bentonite slurry 30 mixed with a filling-up material invading into and filling up a void and a crack formed in an inner wall surface of the rock-bed cavity and a lower layer composed of a heavy bentonite slurry 13 mixed with a high specific gravity fine powder as a load condition material. The filling-up effect of the bentonite slurry secures sufficient liquid-tightness and air-tightness in the ceiling part of the rock-bed cavity, making it possible to efficiently and economically store compressed gases such as compressed air or natural gas without allowing them to escape.

    • A duplicating photosensitive material film is brought into close contact with an ND glass reduced in thickness so as to become flexible or a flexible sheet or an ND glass coated with a cushioning layer through an optical contacting liquid containing a surface active agent. In addition, a spacer is interposed between a hologram original plate and a duplicating photosensitive material, and a space defined by the spacer is filled with an optical contacting liquid, thereby regulating the thickness of the optical contacting liquid layer with the spacer. Therefore, when pressure is applied, the optical contacting liquid is uniformly pressed, so that it can be made uniform and thin in thickness. Accordingly, it is possible to prevent a failure of duplication of a hologram image due to undesirable flow of the optical contacting liquid. In addition, the wettability of the optical contacting liquid improves, so that it is possible to prevent trapping of air and foaming and to make the optical contacting liquid uniform and thin in thickness. Thus, it becomes possible to duplicate a hologram image excellently. In addition, a cushioning layer is provided on the inner side of an AR coated ND glass or on the upper side of a photosensitive material film, and another cushioning layer is provided on the side of an original plate protecting glass which is closer to the optical contacting liquid or on the lower side of the photosensitive material film. With this arrangement, even if dust enters, it can be effectively held inside the cushioning layers. Thus, it is possible to prevent undesirable flow of the optical contacting liquid and lifting of the film due to dust and hence possible to perform duplication effectively without any hindrance. Also disclosed is a hologram producing apparatus which includes mechanisms for feeding and taking up a duplicating photosensitive material film, and a contacting liquid dropping mechanism. The apparatus further includes a mechanism for nipping an excess of contacting liquid dropped, a mechanism for drying the contacting liquid attached to the exposed duplicating photosensitive material film, a mechanism for positioning the film, etc.
