The mask has a pattern formation surface on which the pattern is formed and that is placed around a predetermined axis, and the mask is able to rotate, with the predetermined axis taken as an axis of rotation, in synchronization with a movement of the substrate in at least a predetermined one-dimensional direction. When a diameter of the mask on the pattern formation surface is taken as D, and a maximum length of the substrate in the one-dimensional direction is taken as L, and a projection ratio of the projection optical system is taken as ?, and circumference ratio is taken as ?, then the conditions for D?(?×L)/? are satisfied.

Abstract: In a multi-exposure drawing method for drawing a pattern on a drawing surface, using an exposure unit including a plurality of optical modulation elements arranged in a matrix manner, the unit is continuously and relatively moved at a constant velocity with respect to the drawing surface in an array-direction defined by a matrix-arrangement of the modulation elements. Optical modulation elements, spaced at a regular interval in an alignment of optical modulation elements along the array-direction, are successively and selectively driven based on a same bit datum, to thereby modulate a light beam made incident thereon, whenever the exposure unit is moved by a distance corresponding to the regular interval, resulting in the production of a pixel dot on the drawing surface in a multi-exposure manner by the modulated light beams.

Abstract: A semiconductor manufacturing station (50) exposes light on a surface area of a spherical semiconductor device or ball (52). A mask pattern generator (56) provides a pattern of light, which undergoes temporal changes to collectively represent an image. The mask pattern generator has an active exposure contour (80) that provides a portion of the overall image. The pattern of light is directed though a lens (62) to the surface area of the semiconductor device. The semiconductor device rotates in relation to the temporal changes in the pattern of light to expose the pattern of light over a portion of a surface area of the semiconductor device. The exposure contour has a narrower center and becomes wider moving away from the center. The exposure contour may have a curvature.

Abstract: The axial length of a center roller (subroller) (30) is made shorter than the axial length of a main roller (28), and the center roller (30) is placed so that an axis of the center roller (30) is parallel to an axis of the main roller (28) in a base position and so that a nipping pressure is generated in the center position in the axial direction of the main roller (28). A film (sheet) (20) is thereby subjected to a tension in the center portion thereof due to the pulling force of the center roller (30), and the feeding amounts of the film (20) at the left and right portions therefore vary relative to each other. The film (20) thus displaces in the axial direction of the main roller (28) around the center roller (30).

Abstract: A rotating drum recorder includes a rotatable mounted drum having a cylindrical outer surface and an internal cavity adapted to receive a strip of light-sensitive recording material. An exposure gate defines (1) an aperture extending through the cylindrical outer surface of the drum and (2) a radially inwardly-facing media-locating surface. A drive mechanism is adapted to transport a received strip of light-sensitive recording material through the exposure gate internal to the cylindrical outer surface of the drum, whereby centrifical force on the strip of light-sensitive recording material acts to press the strip of light-sensitive recording material against the media-locating surface of the exposure gate as the drum rotates. The exposure source includes a source of a collimated light beam and an electro-optic modulator between the source and the drum surface for varying the intensity of the collimated light beam.

Abstract: A printer film carrier turning apparatus for obtaining a photograph by irradiating light onto a film comprises a film carrier for supporting the film, a carrier supporting table for supporting the film carrier parallel with the film to make the film carrier turn through a 90.degree. range, and a light diffusion box for diffusing illuminance light to uniformly illuminate a film range which is to be printed. The film turning apparatus is constructed such that the film carrier turns in unison with the light diffusion box. Therefore, transferring rollers of the film carrier cannot interfere with the light diffusion box, which allows the light diffusion box to be placed very close to the film carrier and thereby increases the efficiency of the light source. Also, the film carrier can be turned in unison with the light diffusion box, thereby improving the operating mechanism.

Abstract: An original drum and a recording drum are driven independently by individual synchronous motors. Encoders output respective rotation timing pulses (P.sub.a, P.sub.b) at every rotation of the recording drum and the original drum. If an interval separating the timing pulses (P.sub.a, P.sub.b) becomes smaller than a prescribed value, a scanning line deviation control circuit generates a motor control signal (T.sub.b) which interrupts the delivery of electrical power to the faster moving motor for a limited period such as to restore a correct relationship between the timing pulses.

Abstract: By means of two cylinders each composed of two interconnected discs, and which cylinders are rotatable in synchronism about a common axis and respectively transport along portions of their circumference an image carrier and a copy carrier, such carriers are continuously forwardly moved at identical angular velocities. A light source projects the negative located at the image carrier through an objective arranged at the common axis upon the copy carrier. The magnification and ratio reduction ratio is proportional to the ratio of the diameters of both cylinders. The light beam which passes through a slotted diaphragm projects continuously and in a strip-shaped configuration the negative from the image carrier to the copy carrier with constant opposite sense movement of such image and copy carriers.

Abstract: A printing head assembly is disclosed for use in a contact film printer for exposing raw stock film with a preprint film or negative. The printing head assembly includes an aperture jaw through which light is projected onto the film strips to transfer the images from the preprint film onto the raw stock. The printing head is adapted to be mounted with the aperture jaw adjacent a drive sprocket for driving the film webs past the aperture in a contact relationship and at a predetermined rate. The edge of the preprint film strip opposite the drive sprocket is supported by a shoulder or idler ring rotatably mounted within the printing head by a stationary support shaft. The support shaft is mounted with its axis extending at a small angle with respect to the horizontal. The rotating shoulder thus rotates in a plane offset from the vertical to permit sufficient clearance for the printing light beam to be projected through the printing aperture.
