摘要： An image that has been displayed on the display screen of an image generator is first passed through a projection lens section consisting of a front group and a rear group. Next after being reflected on the reflecting surface of a free-form surface mirror, the image is further reflected by a planar reflecting mirror and then obliquely projected from the lower section of a projection screen onto the screen. The front group of the projection lens section is provided for enlarging the image. In order to correct aberration due to oblique projection onto the projection screen, the rear group uses a free-form surface lens that forms a concave shape with respect to the exit side of light from the lens. The free-form surface mirror corrects trapezoidal distortion due to oblique projection onto the projection screen. The free-form surface lens in the rear group of the projection lens section can accommodate changes in environmental conditions by using one edge as a reference edge and rendering the other edge expandable. The free-form surface mirror can likewise use one edge as a reference edge and render the other edge expandable. For adjustment, the free-form surface mirror can also be pivoted about the reference edge.

摘要： When one or more storage data are coincident with single search data (12), an associative memory (1) carries out logical sum for all of storage data with a valid state for storage data as true. The result of logical sum is used as matched data logical-OR information. In a primary searching operation, the associative memory (1) is supplied with the search data (12) to provide the matched data logical-OR information on matched data logical-OR lines. Then, the associative memory (1) carries out a secondary searching operation supplied as search data with the matched data logical-OR information obtained by all of storage data coincident upon the primary searching operation. Only a match line (5) coincident with the matched data logical-OR information is selected as the secondary search result. The associative memory is used in a network router to calculate an optimum memory address signal (403) by encoding the selected match line (5). In response to the memory address signal (403), a memory data signal (405) enabling shortest network connection is produced as a transfer network address (413). The transfer network address (413) is combined with a data area (412) and a destination network address (411) contained in input transfer data (408) to produce output transfer data (409).

摘要： A projection lens system for enlarging and displaying on a screen an original image from an image generating source, includes a first lens having positive refractive power, a second aberration correction lens, and a third lens, positioned nearest the image generating source and having a concave lens surface thereof facing the screen. The third lens has a profile such that its refractive power at a marginal area adjacent a peripheral edge thereof is less than its refractive power at an area adjacent an optical axis of said projection lens system. The surface of the third lens facing the image generating source is in contact with a cooling liquid which cools the image generating source.

摘要： In a multiple determination apparatus for determining whether or not a dividend is a multiple of a divisor which is represented by D=.alpha..multidot.2.sup.r where .alpha. is an odd number and r is 0, 1, 2, . . . , a non-zero determination circuit determines whether or not a remainder of a division of the dividend by 2.sup.r is zero. A selector circuit replaces a first number with a quotient of the division. An operational circuit determines whether or not a greatest common measure between .alpha. and the first number coincides with .alpha., when the remainder is zero. Thus, it is determined that the dividend is a multiple of the divisor when the greatest common measure coincides with .alpha..

摘要： When a projection lens system used for a rear projection type image display apparatus has a first lens group having an aspherical lens surface, a second lens group, a third lens group sharing almost all the positive refractive power of the overall system, a fourth lens group having an aspherical lens surface, a fifth lens group, and a sixth lens group including a lens having a profile of aspherical surface in which the concave surface thereof faces the screen side and the refractive power in the marginal area is weaker than the refractive power around the optical axis, a projection lens system having a large aperture ratio (low F-number), high focus, wide field angle, and sufficient marginal light amount ratio can be realized at a low cost. When a predetermined opening portion is formed in the projection lens and lens barrel, the lens elements are cooled by air suction and exhaust and the lowering of the lens performance due to temperature change can be prevented. When a flange is arranged in a suitable location of the opening portion, entry of a foreign material from the opening portion and light leakage from the inside are prevented and the contrast performance of the projection type image display apparatus can be prevented from lowering.
