Abstract: An image pickup lens unit includes, as viewed from an object side, a retainer having an aperture stop, an image pickup lens, and a holder. The retainer having an aperture stop and the image pickup lens are united with each other. The holder assumes a substantially cylindrical shape and accommodates the image pickup lens such that the image pickup lens is united with the holder in a manner movable in relation to the holder, whereby movement of the retainer having an aperture stop causes the image pickup lens to move in relation to the holder to thereby carry out focus adjustment.

Abstract: The present invention presents a particle-size distribution measuring apparatus which allows measuring simultaneously the dispersion state of particles in suspension medium and the particle-size distribution of the particles. The present invention is a particle-size distribution measuring apparatus which measures the particle-size distribution of particles included in a sample. The particle-size distribution measuring apparatus comprises a pH meter for measuring the pH value of the sample and an information processing portion which determines the relation between the pH value and the particle-size distribution on the basis that the pH value measured by the pH meter and the measured particle-size distribution are in the same state.

Abstract: A substrate (25) and a lens holder (26) for supporting an objective lens (52) of the lens driving apparatus are integrally molded by synthetic resin using a predetermined mold. In the case of the integral molding, while long lengths of projection portions (31, 32, 33, 34) are integrally molded in four corners of the substrate (25), elastic wires (27, 28, 29, 30) are buried in the rear ends (47, 48, 49, 50) of the substrate (25) and are supported. By filling gaps (39, 40, 41, 42) defined by the projection portions (31, 32, 33, 34) and the substrate (25) by this integral molding with ultraviolet cure resins (43, 44, 45, 46) to cure the resins, the elastic wires (27, 28, 29, 30) are buried in the ultraviolet cure resins (43, 44, 45, 46).

Abstract: A synthetic erector lens mount for use in a rifle scope or similar optical instrument incorporating glides, or rails, which ride on the inner surface of the guide tube. Biasing fingers, or tabs, incorporate raised bulges, or angle radially outward from the body of the mount, or both, so that they push outward on the walls of the guide tube, pushing the mount against the glides. Preferably the mount incorporates a recess on the inner wall of the mount for capturing a nut or other fastener, a hole through the wall of the mount, and a flattened area of the outer surface of the mount, parallel to the recess and aligned with the hole, for removably attaching a guide sleeve which engages the slots in the guide tube and cam tube for adjustment of the erector lens.

Abstract: The present invention relates to an image reading apparatus which has an original supporting surface on which a sheet original is placed, reading means for reading an image of the sheet original placed on the original supporting surface, and an abutting portion which is provided on the original supporting surface and against which an end portion of the sheet original abuts, and the autting portion has a positioning portion for positioning the end portion of the sheet original so that when the original supporting surface is brought into an inclined state with respect to a horizontal, the sheet original may not float up relative to the original supporting surface.

Abstract: A bayonet fixing device includes a cylindrical member; an annular member attached to one end of the cylindrical member; and a retainer ring attached to the cylindrical member to fix the annular member to the cylindrical member. The cylindrical member includes engaging lugs and insertion areas which are alternately arranged along the circumference at one end of the cylindrical member; grooves formed behind the engaging lugs; and recesses formed behind the grooves. The annular member includes a plurality of projections which are respectively fitted into the recesses via the insertion areas and the grooves. The retainer ring includes engaging blades which are fitted into the grooves via the insertion areas to be positioned between the engaging lugs and the projections in an axial direction of the cylindrical member.

Abstract: To image the surface, provided with an analysis preparation, of the bottom of a well of a microtiter plate (16) made of a transparent material, provision is made for an optical system with a magnifying objective and an incident-light illumination formed by an annular, diffuse light source (15) which is arranged concentrically with the optical axis (19). The microtiter plate (16) has its rear side illuminated by an approximately point-shaped light source (17) arranged behind a diffuser disk (18) and located centrally relative to the optical axis (19). Reflections and material interferences occurring in the area lying outside the measurement surface subject to evaluation are thereby rendered invisible.

Abstract: In a liquid-crystal display device, a light pipe including an upper surface, a lower surface opposite to the upper surface, an incidence side surface, and a light output means formed in the upper surface is provided, the light pipe has a retardation of not larger than 40 nm between the upper and lower surfaces. Further, a light source is disposed on the incidence side surface, a reflection layer is disposed on the lower surface, and a liquid-crystal shutter is disposed on the upper surface and includes a liquid-crystal cell and at least one polarizer. Light incident on the incidence side surface from the light source goes out from the lower surface through the light output means, the outgoing light is then reflected on the reflection layer, and the reflected light is then transmitted through the light pipe so as to go out from the upper surface finally.

Abstract: An optical device that modifies a conventional anisotropic lens array to enable the viewer to perceive a repertoire of preselected images over a first range of angles of regard or to see through the device to a scene beyond the device without distortion. The preselected images in one orientation gives the illusion of a repertoire of images at differing depths. The preselected images at a second orientation can produce a set of optical effects wherein one image gradually transforms to another, or the repertoire of images are unrelated and change suddenly one to another or the repertoire of images are frames of a motion scene or finally, the repertoire of images represent a scene at differing magnifications. The optical device provides distortion-free windowing and a reasonably rich repertoire of images. The device may also be applied to applications requiring optical anisotropy such as privacy filtering.

Abstract: An erect image magnifying lens device having a higher magnification is provided. The erect image magnifying lens device comprises a display element for displaying an image; a fresnel lens provided on the display element for refracting a light emitted by the display element to a direction to magnify the image; an erect image magnifying lens consisted of stacked two micro-lens arrays and positioned in opposition to the fresnel lens; and an image plane positioned in opposition to the errect image magnifying lens, on which the image from the display element is formed.
