Publication number: 20150161006Abstract: A method is provided for testing a processor of an information processing apparatus that includes a cache memory, a first memory, and a second memory. Backups of a first instruction sequence and first data that, when a modification is made thereto, is incapable of being recovered using an instruction sequence held in the first memory are made in the second memory, the second memory being not accessed by the cache memory. In causing the processor to execute the instruction sequence, a second instruction sequence and second data that is fetched and put in the cache memory is modified. While the processor is executing the instruction sequence, when an error occurs due to a modification in a third instruction sequence that is incapable of being recovered using the instruction sequence, the first instruction sequence in the second memory is written to the first memory.Type: ApplicationFiled: October 27, 2014Publication date: June 11, 2015Inventors: Akira NAKAMIZU, Tatsuki KOBAYASHI, Tetsuya MORIOKA, Hiroki NARITA

Patent number: 5039614Abstract: An automated, on-line solvent elimination interface system is described for use in characterizing the Composition Distribution (CD) of unknown materials emerging from a fractionating unit or a process stream. Fractionated samples to be analyzed, such as a polymer, in highly diluted form in one or more solvents, are provided by a fractionation unit such as a gel permeation chromatograph (GPC), a high pressure liquid chromatograph (HPLC), or a field flow fractionator (FFF). A number of discharges of each particular fraction are supplied to individual collection units within the interface system under controlled conditions of flow rate, temperature and pressure (vacuum) such that the solvents are flash-evaporated at the collection unit. A sufficient solid residue is built up on the collection unit for analysis by, for example, a Fourier transform infrared (FTIR) analyzer.Type: GrantFiled: June 15, 1990Date of Patent: August 13, 1991Inventors: Armenag Dekmezian, Tetsuya Morioka
