摘要： When one or more storage data are coincident with single search data (105), an associative memory with a shortest mask producing function carries out logical multiplication for all of mask information corresponding to the coincident storage data with a mask valid state as true. The result of logical multiplication is used as shortest mask information. In a primary searching operation, the associative memory with a shortest mask producing function is supplied with the search data (105) to provide the shortest mask information on shortest mask lines. Then, as a secondary searching operation, the shortest mask information thus extracted is used as the search data and supplied to the associative memory with a shortest mask producing function. Among the coincident storage data, only a mask match line connected to a particular word having mask information coincident with the shortest mask information is selected as the secondary search result. The associative memory is used in a network router, to calculate an optimum memory address signal (303) by encoding the selected mask match line. In response to the memory address signal (303), a memory data signal (305) enabling shortest network connection is produced as a transfer network address (313). The transfer network address (313) is combined with a data area (312) and a destination network address (311) contained in input transfer data (308) to produce output transfer data (309).

摘要： There is provided a projection image display apparatus which is excellent in quality of a display screen image even if a projection lens using a plastic lens having an asymmetrical shape with respect to an optical axis is used. The apparatus includes a projection lens which obliquely projects video light on a screen, an integrator which aligns a polarization direction of light from a light source, and an image display element (P, PL) which modulates light having the aligned polarization direction by an image signal. The projection lens includes multiple plastic lenses, and each of the multiple plastic lenses is arrayed, respectively, by shifting a gate direction to each other by 180 degrees. When the projection lens includes n sheets (n is a natural number) of plastic lenses, each of the multiple plastic lenses may be arrayed, respectively, by shifting a gate direction to each other by (360/n) degrees.

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： An associative memory 4 for primary searching operation of an associative memory 23 supplies a valid state to a primary match line 13 corresponding to storage data coincident with search data 10 taking mask information into account, and supplies a value obtained from a result of a logical sum operation (an OR operation), with a valid state for the storage data as true, of all said coincident storage data to a counting means 25 as intermediate data 15. The counting means 25 supplies a result of an operation to the intermediate data 15 for counting the number of bits in an invalid state for the storage data to an associative memory 3 for secondary searching operations as secondary search data 19. Among secondary storage data obtained by carrying out said operation to said storage data, the associative memory 3 for secondary searching operation supplies a result of carrying out the searching operation of the secondary search data 19 to a secondary match line 21. The invalidation means 22 changes a secondary match line 21 corresponding to a primary match line 13 in an invalid state into an invalid state to supply to an external source as a match line 11.

摘要： An image that has been displayed on the display screen of an image generator 1 is first passed through a projection lens section 2 consisting of a front group and a rear group. Next after being reflected on the reflecting surface of a free-form surface mirror 5, the image is further reflected by a planar reflecting mirror 4 and then obliquely projected from the lower section of a projection screen 3 onto the screen 3. The front group of the projection lens section 2 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 5 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 2 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.
