A cover plate for covering an opening of a casing in which a solid state imaging device is disposed. The cover plate comprises a transparent cover plate member and a conductive film layer. The cover plate hermetically covers the opening of the casing and the conductive film layer covers the outermost surface of the transparent cover plate member. The transparent cover plate member is comprised of a plurality of laminated transparent plates such as lithium niobate plates for an optical low-pass filter and a plate for an infrared cut-off filter. An example of the conductive film layer is a metallic film such as Cr or Au, coated on the surface.

An electronic camera is provided that prevents deterioration of quality of an object image obtained by an image-pickup device due to dust adhered on an optical element. The electronic camera includes an ion generator for taking off the electric charges from the optical element, such as a low-pass filter, arranged in front of the image-pickup device. The ion generator is provided in the camera body and ionizes the air inside the camera body. The ionized air diffuses toward the low-pass filter and binds with the charge on the low-pass filter. Thus, the electric charge of the low-pass filter is taken off and the low-pass filter does not attract dust which cause the quality decrease of the object's image obtained by the image-pickup device.

There is provided a method of processing an optical fiber having a core and a clad. The optical fiber has a first facet and a second facet. The method includes fixing the optical fiber in a state in which at least a portion thereof is bent in a predetermined curvature radius, applying a resist to a region on the first facet at least including an entirety of the core, irradiating the second facet with light of a predetermined wavelength so that only the resist applied to the core in the first facet is exposed to the light through an inside of the optical fiber, developing the resist, and forming a level gap at a boundary between the core and the clad in the first facet utilizing the resist remaining after the irradiating and the developing.

There is provided an optical communication apparatus, which is provided with a light emitting device that emits a transmission light signal modulated with transmission data, an optical fiber, and a deflecting system that is located between the light emitting device and the optical fiber so as to move a position of the transmission light signal on an entrance surface of the optical fiber. The optical communication apparatus is further provided with a feedback control system that controls the deflecting system so as to move the position of the transmission light signal to a center of a core of the optical fiber based on intensity of a portion of the transmission light signal.

In a manufacturing method of a spacer for an electron-beam apparatus which includes an airtight container and an electron source, the spacer is arranged in the airtight container. The method includes the step of heating and drawing a base material of the spacer to form a desired rough state on the surface of the base material, the step of heating and drawing the base material of the spacer to form the desired rough state and an electroconductive film on the surface of the base material, or the step of heating and drawing the base material of the spacer having the rough state on its surface. According to the present invention, the spacer having a surface structure which can suppress charging can be manufactured at a low cost, and an electron-beam apparatus such as an image-forming apparatus having a sufficient display luminance can also be manufactured.

A support member (20) for maintaining the distance between a face plate (30) and a rear plate (31) is interposed between the face plate (30) and the rear plate (31). An insulating film is formed on the support member (20) or its surface. An intermediate layer (21) is formed at a portion near the rear plate (31). The intermediate layer (21) is set at a low resistance and the same potential as that of the rear plate (31). As a result, an electron beam emitted from an electron-emitting portion near the support member (20) follows an orbit which is directed temporarily away from the support member and then comes close to the support member near the face plate (30) due to the steady charge-up of the support member. Then, the electron beam is irradiated on a defined position on the face plate (30).

In an image forming apparatus, a support member (50) for maintaining the distance between a face plate (30) and a rear plate (31) is interposed between the face plate (30) and the rear plate (31). An intermediate layer (52) is formed at apportion near the face plate (30). The intermediate layer (52) is a low-resistance film, and is set to have almost the same potential as that of the face plate (30). As a result, an electron beam from an electron-emitting portion near the support member (50) follows an orbit which steadily comes close to the support member near the face plate. By setting the interval between electron-emitting devices adjacent to each other via the support member to be larger than the interval between devices adjacent to each other without the mediacy of the support member, the electron beam is irradiated on a proper position on the face plate (30).

Anodic bonding of an insulator containing no movable ion and a conductor through the medium of a conductive film and an insulator layer containing a movable ion affords a bonded member of the insulator containing no movable ion and the conductor without use of any adhesive agent. A method for effecting the anodic bonding is also provided.

A microactuator having a piezoelectric material and a drive electrode formed adjacent to the piezoelectric material is manufactured by forming an electroplating electrode on a substrate and providing a photosensitive material layer on the substrate on which the electroplating electrode is formed. The photosensitive material layer is exposed in a desired pattern. The exposed photosensitive material layer is developed to partially remove the exposed photosensitive material layer. A metal with electroplating is filled in a substrate portion from which the photosensitive material layer is removed, so that a drive electrode is formed. A remaining photosensitive material layer is removed. Finally, a piezoelectric material is selectively filled in a substrate portion adjacent to the drive electrode.
