Abstract:
A circuit pattern surface curving in correspondence with the surface shape of a ball-like semiconductor device material such as a silicon ball is formed in a reticle. A resist-applied surface of the device material is so exposed as to move the ball-like semiconductor device material close to the circuit pattern surface. In this manner, a circuit pattern is formed on the surface of the ball-like device material.
Abstract:
A projecting device comprising an array of axial element lens systems, wherein each element lens system includes a single bar lens having an axial length larger than the effective aperture and adapted to form an intermediate image of a pixel of the object plane and an erect image of a magnification of unity not vertically nor laterally inverted in such a manner that the light intensity on the image plane corresponding to said pixel is defined in the form of Gaussian distribution by the eclipse of the aperture. The element lens systems are arranged in a plane perpendicular to the optical axis so as to cause the light intensity distributions of said systems to mutually overlap in the peripheral areas thereof on the image plane, wherein each row of the systems in the array is displaced by a half pitch with respect to the neighboring row to constitute a staggered arrangement thereby achieving a uniform exposure distribution, integrated in time, in the scanning direction.
Abstract:
A projection apparatus for forming an image of original on a photosensitive material opposed to the plane of the original. The projection apparatus has a projecting system composed of a plurality of projection optical system arrays. Each individual projection optical system is composed of a first and a second lens coaxially disposed and having a relatively large length as compared with its effective lens diameter respectively. The first lens is an exit side telecentric lens whereas the second one is an incident side telecentric lens. The first lens forms an intermediate image of a portion of the original on a plane between the first and second lenses and the second lens reforms the intermediate image on the photosensitive material.
Abstract:
A copying apparatus comprising a flat stationary original support table, at least a movable mirror for scanning the surface of an original placed on said original support table, and an imaging optical system adapted for focusing the light beam from said movable mirror onto a photosensitive member and capable of compensating the change in the light path length from said original support table to the photosensitive member resulting from the displacement of said movable mirror while maintaining a constant image magnification.

A scanning device for scanning a flat scanned surface by means of a rotating or rotatively vibrating deflector. The scanning device is provided with a rotational asymmetric image forming optical system disposed between the deflector and the scanned surface for forming an image of the scanned surface at a substantially equal distance from the deflecting surface of the deflector in the plane defined by the path of movement of the normal to the deflecting surface of the deflector in accordance with the rotation thereof.
Abstract:
A light beam scanning device provided with a rotationally vibrating deflector having at least two deflective and reflective surfaces, a scanning surface subjected to scanning operation with light beam deflected by the deflector, an image-forming optical system interposed between the deflector and the scanning surface to focus the light beam from the deflector onto the scanning surface, and a light source section which emits light beam to the deflector, in which device a first deflected light beam plane to be formed by the deflected light beam immediately before entering the image-forming optical system at the forward movement of the deflector is made parallel with a second deflected light beam plane to be formed by the deflected light beam immediately before entering the image-forming optical system at the return movement of the deflector, and the deflecting direction of each beam to be deflected by the first deflected light beam plane and the second deflected light beam plane is made identical.
Abstract:
A projecting device is disclosed which has plural element lens systems arranged in at least two rows in a staggered fashion in two grooved blocks, with one row displaced relative to the adjacent row by a distance equal to half the pitch of the adjacent row. Each lens system is composed of at least one bar lens for imaging a part of the object as a part of the corresponding image. An opaque elastomer material fills the space between the rows for preventing light from entering into the space while allowing the positional relation between the rows to be fine-adjusted.
Abstract:
This specification discloses a projection device in which a plurality of element lens systems for projecting a part area of an object onto a predetermined part area on the image plane at erect one-to-one magnification are arranged parallel to one another in a plane perpendicular to the optical axis. Each element lens system is a telecentric system comprising three thin lenses of the same shape arranged in the direction of the optical axis, and an intermediate lens is provided at a position deviated from the intermediate point between the object side lens and the image plane side lens. A light absorbing member for extinguishing any light rays exceeding the effective lens diameter is provided between the lenses, and the light intensity distribution on the image plane of each element lens system is controlled substantially to Gauss distribution form by aperture eclipse and, even if there is any error in the arrangement interval, the exposure amount distribution in the arrangement direction superposed on the image plane is uniform.

Abstract:
An ommateal image projector of a type, in which a single or a plurality of rows of the so-called bar lenses having a longer length in the direction of its optical axis than the effective lens diameter thereof are arranged, each bar lens projecting a partial image of an object to be projected onto a mirror surface, and the partial image formed on this mirror surface forming again this partial image onto the image projecting surface by the same bar lens. The entire image of the object is formed on the projecting surface by row of the bar lenses, and the total image thus formed is an erected image.
