Abstract: A liquid germicide is measured; the measured liquid germicide is injected into hollows of concave articles (1); the more or less of volume of the liquid germicide is discriminated from the injected liquid germicide; only concave articles (1) which each have a proper volume of the liquid germicide attached thereto are stored into a storage (6); thereafter the storage is closed, and the concave articles are left to stand in the closed storage for a prescribed period of time. Since the liquid germicide is injected into the hollow of the concave article (1) after measuring, and the more or less of volume of volume of the solution is discriminated from the injected liquid germicide as described above, it is possible to attach a proper amount of liquid germicide to concave article (1) such as vessel or preform, and hence to accomplish efficient sterilization in the storage (6), without the risk of the defective sterilization.

The coating die head includes a lip 12b having a lip surface 12b and a side having a side surface 12c. A contact angle of the surface 12c with respect to the coating liquid is greater than a contact angle of the surface 12b with respect to the coating liquid. This configuration enhances stabilization of bead of the coating liquid during application process of the coating liquid, preventing stripes and steps from appearing in the coating layer. This coating die head makes it possible to carry out high precision coating required for fabrication of color filters for liquid crystal displays.

Abstract: A projection screen includes a cholesteric liquid crystalline, polarized-light selective reflection layer for selectively diffuse-reflecting a specific polarized-light component. The layer has, on its observation-side surface, a roughened part for controlling the direction of interfacial reflection of imaging light that is projected on the layer. Imaging light projected on the projection screen from a projector enters the layer and is diffuse-reflected inside this layer; this light is diffused as diffuse-reflected light, in directions included in an approximately constant range. On the other hand, part of the light projected on the projection screen from the projector is reflected, by interfacial reflection, from the inclined planes of the roughened part. The reflected light emerges from the layer in a direction different from the main direction in which the light diffuse-reflected from the layer emerges and returns to the observation side as light reflected by interfacial reflection.

There is thus finally obtained an optical element 10 comprising the cholesteric layer 12 formed on the alignment substrate 13.
