Filed: 1992-02-17
Abstract: PURPOSE: To accelerate the access speed of main memory data by a computer processor. CONSTITUTION: A computer system is composed of a data processor 26, a main memory 20, a cache memory 14 and an in-page buffer 12. A part of line data bypasses the in-page butter 12 and is transferred to the cache memory 14 first and the remainder is transferred to the in-page butter 12 in succession. The processor 26 accesses data inside the cache memory 14 by one set of clocks, and in the meantime, the remaining line data are transferred to the in-page butter 12 by the different set of the clocks. The two sets of the clocks optimize the operations of the processor and the main memory. Contents inside the in- page buffer 12 are continuously transferred to the cache memory 14 at the time of starting a different in-page operation, and in the meantime, the next line data are fetched from the main memory 20.

Filed: 1992-01-21
Abstract: PURPOSE:To prevent the deterioration of the previously formed thin oxide superconducting film by coating the specific region of a heater surface with the above device having a substrate holder contg. the heater and a vacuum chamber housing a target holder. CONSTITUTION:The target 4 held on the target holder 5 is irradiated with a laser beam from a laser device 10 via a window 9 of the vacuum chamber 8 by using, for example, a laser vapor deposition device, by which the thin oxide superconducting film is formed on a substrate 2 heated by the heater 1 built in the substrate holder 3.
