    • A CVD apparatus for fabricating a titanium nitride thin film is provided. The apparatus comprises an evacuatable reaction vessel having an interior, a pumping apparatus capable of exhausting the reaction vessel and maintaining the interior of the reaction vessel at a prescribed pressure, a gas feeder for introducing a mixed gas into the reaction vessel, a substrate holder in the reaction vessel for holding a substrate to be coated with a titanium nitride thin film, and a heater for heating the substrate. The gas feeder is equipped with the following components: (a) a vaporizer for vaporizing tetrakis(dialkylamino)titanium (TDAAT) from a liquid source material, (b) a first flow controller capable of setting a flow rate of the vaporized TDAAT to any level within a range of 0.004-02 g/min, (c) a second flow controller capable of setting a flow rate of a first carrier gas mixed with the TDAAT to any level within a range of 100-1000 sccm, (d) a third flow controller capable of setting a flow rate of an added gas reactable with the TDAAT to any level within a range of 10-100 sccm, (e) a fourth flow controller capable of setting a flow rate of a second carrier gas being mixed with the added gas to any level within a range of 10-500 sccm, (f) a first supply conduit for mixing the TDAAT and the first carrier gas to create a first mixed gas and guiding the resulting first mixed gas into the reaction vessel, (g) a second supply conduit for mixing the added gas and the second carrier gas to create a second mixed gas and guiding the resulting second mixed gas into the reaction vessel, and (h) a shower head which is provided with a plurality of first nozzles connected to the first supply conduit, and a plurality of second nozzles connected to the second supply conduit, and which is configured such that the first and second mixed gases are fed into the reaction vessel through the nozzles.

    • 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.

    • 将复制的感光材料膜通过含有表面活性剂的光学接触液体与薄的柔性ND玻璃或涂有缓冲层的ND玻璃紧密接触。 在全息图原版和复制感光材料之间插入间隔物,并且由间隔物限定的空间填充有光学接触液体,间隔物由此调节光学接触液体层的厚度。 此外,在AR涂覆的ND玻璃的内侧或感光材料膜的上侧上设置缓冲层,在全息原版的原版保护玻璃的侧面设置另一缓冲层, 更靠近光学接触液体或感光材料膜的下侧。 通过这种布置,即使灰尘进入,也可以有效地保持在缓冲层内。 因此,可以防止光学接触液体的不期望的流动和由于灰尘而导致的膜的提升,从而可能在没有任何障碍的情况下有效地进行重复。
