A metal annular gasket comprising an annular metal base plate; a compound layer integrally laminated on both surfaces of the annular metal base plate, the compound layer being made of synthetic resin or a rubber material mixed with a fiber material; and an annular seal layer having a circumferential covering portion which covers the inner circumferential edge of the annular metal plate and the inner circumferential edge of both compound layers, the compound layer being made of synthetic resin or a rubber material. The annular seal layer is formed such that the surface of the annular seal layer is so connected to the surfaces of the compound layer as to provide smooth transition in its thickness direction.

Disclosure of information is controlled selectively depending on users such that a plurality of users having different roles bearing no inclusive relation with one another can access the same area. Content is divided into a plurality of areas. For each of the areas obtained by division, secret keys (encryption/decryption keys in symmetric-key cryptography) are generated. The generated keys are encrypted using public keys in public-key cryptography, which are set in advance for the users depending on their respective roles. In the case where the content is to be disclosed to a plurality of users having different roles, the encryption of secret keys is performed separately for each user. These encrypted contents and encrypted secret keys are used to generate encrypted text.

The present invention provides an imaging lens device, which has a widely extended focusing range and exhibits good resolution over the entire focusing range. The imaging lens device comprises a liquid crystal lens for focusing an object at a prescribed distance, comprising a liquid crystal layer, a first transparent substrate disposed adjacent to one surface of the liquid crystal layer and having a first electrode and having Fresnel lens surface formed on the boundary with the liquid crystal layer, a second transparent substrate disposed adjacent to the other surface of the liquid crystal layer and having a second electrode; a controller for changing the refractive index of the liquid crystal layer for extraordinary ray by changing electric voltage applied between the first electrode and the second electrode; and an imaging element for taking an image of the object. The liquid crystal lens functions as a diffractive optical element for an extraordinary ray when the liquid crystal layer has a prescribed refractive index for an extraordinary ray incident upon the liquid crystal layer.

When a ratio R between a total angle φ of a widening angle in a median intensity of light of a light source (a GaN based semiconductor laser) and a total angle 2/φ of a widening angle of light defining a numerical aperture NA of a collimator optical system (collimator lens) is defined as R=(sin−1NA)×2/φ, the numerical aperture of the collimator optical system (collimator lens) is set so that 2.0≧R≧0.58. Thus, an image exposure device is provided that can suppress stray light of a light source that emits a large amount of stray light.
