摘要:
A rotation control device is configured so that a spring force of a torsion coil spring holds an attitude of a rotation body at a pre-advancement position corresponding to a post-return position (a), and a post-advancement position corresponding to a pre-return position (b), respectively. The rotation control device includes a first rotation part supporting one end of the torsion coil spring and supported on a fixed body so as to rotate as the rotation body rotates, and a second rotation part rotatably supported on the fixed body at a first rotation part side and supporting the other end of the torsion coil spring. When the first rotation part rotates, the second rotation part rotates together with the first rotation part. A wound portion of the torsion coil spring is most elastically deformed when the rotation body is at an intermediate position (c) between the position (a) and the position (b).

A lens array includes: a substrate in which a plurality of through holes are formed; and a plurality of lenses provided in the substrate by burying the plurality of through holes. A part of the through hole is different in at least one of sectional shape and opening area of the through hole, which are taken in parallel with a surface of the substrate, from another part of the through hole in a depth direction.

An image-recording apparatus. In a housing of the apparatus are a casing section that encases a light and heat sensitive recording material, an optical recording section that exposes the light and heat sensitive recording material fed from the casing section to record a latent image, a thermal developing section that develops the latent image by heating, an optical fixing section that fixes the developed image by irradiating it with light, and an outlet through which the image-recorded material is taken out.
摘要:
A functional film, which has photo-catalytic effects, is overlaid on a surface of each of at least two substrate materials. The functional film, which has been overlaid on the surface of each of the substrate materials, is exposed to light having a wavelength falling within an absorption wavelength range of the functional film. The substrate materials are then bonded to each other with the functional films, which have been exposed to the light, intervening between the substrate materials. The functional film may be a film containing TiO2, and the light irradiated to the functional film may be ultraviolet light. In cases where a film other than the functional film is also overlaid on the surface of each of the substrate materials, the functional film is formed as a top layer.

摘要:
An image-recording apparatus including a casing section that encases a light and heat sensitive recording material therein; an optical recording section that exposes to light a light and heat sensitive recording material fed from the casing section, and thereby records a latent image thereon; a thermal developing section that develops the latent image with heat; a moisture content-controlling section that controls moisture content of the light and heat sensitive recording material after exposure and before development; and an optical fixing section that fixes the developed image by irradiating it with light. The image-recording apparatus can be a completely dry system that is capable of forming good print images without producing waste materials such as image transfer sheets. By controlling moisture content of the recording material, problems such as mottling of images can be prevented.
摘要:
A ferroelectric substance such as LiNbO.sub.3 that possesses a unipolarized non-linear optical effect is etched on its surface. An earth electrode is formed on one surface (the +z plane) of a ferroelectric substance. Domain reversals are created on the opposite side (the -z plane) of the substrate relative to the +z plane by irradiating electron beams onto the -z plane.
摘要:
An optical wavelength converting apparatus comprises a fundamental wave source, which produces a laser beam serving as a fundamental wave, and an optical wavelength converting device, which is provided with an optical waveguide constituted of a nonlinear optical material. The optical wavelength converting device converts a wavelength of the laser beam impinging upon and guided through the optical waveguide. The optical waveguide is provided with a plurality of periodic domain-inverted structures, which effect phase matching between the laser beam and wavelength-converted waves. Reflection of the fundamental wave or wavelength-converted waves from end faces of the optical wavelength converting device is thereby minimized, and a plurality of wavelength-converted waves having high intensities are obtained in a state combined with one another.
