Abstract: A casing for a projection screen and a motorized projection screen system and method for controlling the same are disclosed herein. The casing includes a fascia and endcaps which are affixed to the casing spine without the use of tools thereby providing easy access to the working components housed within the casing and providing flexibility to the consumer in the appearance of the casing. The motorized projection screen system includes a roller having a projection screen attached thereto and a reversible motor operatively connected to the roller such that rotation of the motor causes the roller to rotate and the projection screen to be raised or lowered. The system also includes a biasing mechanism operatively connected to the roller such that rotation of the roller to lower the projection screen biases the roller toward rotation in the opposite direction. The biasing mechanism reduces the power requirements of the reversible motor of the system as it assists in lifting the weight of the projection screen.

Abstract: A print processing method used in a photographic printer which can print images on a negative film which have different aspect ratios. The print processing method comprises the steps of judging the aspect ratio of each of the images printed on photographic paper, and printing cumulative numbers of prints of each aspect ratio onto the photographic paper of a final printing. The number of prints per aspect ratio can be easily known, and the cost of the prints can be calculated more efficiently.

Abstract: An object of the present invention is to provide an optical system for lithography wherein the zero order component of the main lithographic image is unobstructed and the zero order component in the ghost image is removed. The optical system includes a beamsplitter component and a condensor lens structure for illuminating a lithographic mask from a range of directions which excludes a range of directions that are sufficiently close to the axis to add undesired background to the exposure field after multiple reflections with the lens. The optical system further includes an excimer laser and a lens system having an array of stops for intercepting multiple images of the excimer laser after they reflect from the primary wafer image or other surfaces such as the mask or lens surfaces.The illuminating zero-order beams reflect obliquely off the wafer after contributing to the image, where they are then refocussed to the opposite side of the pupil (the primary mirror).

Abstract: The present invention is a method for forming a graphic image web including a precursor image web combined with a congruent lenticular lens web to produce the illusion of three dimensionality in a visually perceptible image on the graphic image web. To produce this illusion of three dimensionality, an image field including an object is defined. The object is imagewise exposed onto a photographically sensitive element over a plurality of spatially disparate views through a lenticular lens having a prescribed optical geometry. Upon developing the latent image on said element, it is printed to form the precursor image web. The congruent lenticular lens web is then optically combined with the precursor image web to create the graphic image web having graphic information of photographically acceptable quality imparted with the illusion of three dimensionality.

Abstract: A system for producing a full color enlarged reproduction of a color transparency or negative on a photographic paper. The system makes use of a continuous tone scanner having a given contrast range to produce enlarged color separation negatives of the original transparency or negative on a continuous tone photographic film. Prior to producing these enlarged color separation negatives, the continuous tone scanner is adjusted to condensate its contrast range to accommodate the photographic paper. The color separation negatives that are so obtained may be used, after development, for producing the requested full color enlarged reproduction on the photographic paper, using a three color printing system to do so. the color print that is so obtained has an excellent definition and color reproduction.

The aperture member has a light transmission region for transmitting the light from the light source and a light-interrupting member disposed to extend across the light transmission region. The shape or configuration of the light-interrupting member is determined in accordance with the geometry of the circuit pattern formed on the mask.

Abstract: An image forming apparatus is capable of forming a good image without a color shade and a dropped color by coating uniformly photosensitive toner particles on a supporting member. The image forming apparatus includes a coating amount detecting unit for detecting an amount of the photosensitive toner particles coated on the supporting member, in the vicinity of a coating unit. Therefore, the image forming apparatus can determined whether a required amount of the photosensitive toner particles is coated on the supporting member, or not. When a required amount of the photosensitive toner particles is coated on the supporting member, an exposure operation is executed. When there is a part on the supporting member which is not coated with enough photosensitive toner particles, the coating unit is operated again. This processing is repeated until the whole of the supporting member is coated with the enough photosensitive toner particles. After this, the exposure operation is executed.

Abstract: Clamping of different format sizes of film is achieved by aperatured inserts of the required size being insertable in a base member and a platen. The base member is provided with a relatively flat surface and an aperature therein over which a film strip is positioned. The platen is provided with an aperture therethrough and a gripping strips positioned around the periphery of the aperature with the gripping strips being angled away from the aperture. A clamping of the platen to the base member, with said apertures in alignment, provides a tension in the film along all sides of the aperture as the gripping strips are urged outward from the aperture. A two degree of freedom gimbal is formed in the platen to insures that the gripping strips clamp parallel to the aperture plate. Also the design will apply an equal and even clamping force and tension around the film because the two degrees of fredom of rotations are about the center of the clamping plate inserts.

Abstract: Successive exposed photographic films are connected, either individually or in groups of two or more, to discrete sheet-like leaders which are transported along an elongated first path extending through the baths and the dryer of a developing unit. The leaders are separated from the respective webs downstream of the developing unit but upstream of a copying unit for developed films, and the separated leaders are directed into a second path to be gathered in a receptacle. The separation involves severing the leading end of each web close behind the respective leader, and the thus separated webs are caused to continue to advance along the first path through a magazine and thence into the copying unit.
