Patent ES-8606996-A1 (ES)
Title: A method of producing an airtight and waterproof slide fastener.
IPC: A44B19/32
Filed: 1985-05-17
Abstract: A method of producing a slide fastener wherein a series of fastener elements are secured to each of a pair of fastener tapes along one edge each thereof, each said fastener tape is formed thereon with a waterproof sealing layer, and when said series of fastener elements on each said pair of fastener tapes are engaged with each other, the edges of said waterproof sealing layers on each said pair of fastener tapes are press-contacted with each other so as to provide airtightness and waterproofness. The improvement comprises forming said pair of fastener tapes in one piece with a thin connecting portion therebetween, securing a pair of said series of fastener elements to one side of said pair of fastener tapes formed in one piece on the edges along both sides of said connecting portion so that they face each other without being engaged with each other, applying a resiliently deformable waterproof sealing layer all over the other side of said pair of fastener tapes formed in one piece including said connecting portion, then cutting said pair of fastener tapes formed in one piece away from each other longitudinally along said connecting portion so that each cut edge of said waterproof sealing layer projects over a line which will become the center line of engagement of said pair of series of fastener elements when they are engaged with each other. The above method according to the invention produces an airtight and waterproof slide fastener in a simplified manner without impairing the engaging function of the slide fastener and without rendering any damage to the fastener elements.

Patent IE-901529-A1 (IE)
Title: Write back buffer with error correcting capabilities
IPC: G06F/
Filed: 1990-04-27
Abstract: In the operation of high-speed computers, it is frequently advantageous to employ a high speed cache memory within each CPU of a multiple CPU computer system. A standard, slower memory configuration remains in use 10 for the large, common main memory, but those portions of main memory which are expected to be used heavily are copied into the cache memory. Thus, on many memory references, the faster cache memory is exploited, while only infrequent references to the slower main memory are 15 necessary. This configuration generally speeds the overall operation of the computer system; however, memory integrity problems arise by maintaining two separate copies of selected portions of main memory. Accordingly, the memory access unit of the CPU uses error correction 20 code (ECC) hardware to ensure the integrity of the data delivered between the cache and main memory. To prevent the ECC hardware from slowing the overall operation of the CPU, the error correction is performed underneath a write back operation. Data contained in the cache, which 25 will be displaced by data received from main memory 10, is transferred to a write back buffer (WBB) during that period of time between the request for data from the main memory and actual delivery of the requested data. Further, the ECC hardware also operates on the cache data 30 being written to the WBB. Accordingly, a performance penalty is avoided by performing error correction and preremoving the cache data during that idle period of time.
