Patent number: 8516310Abstract: The embodiments provide a failure diagnosis method for a main memory in an information processing device equipped with a write-back cache. According to the method, an application program stored in the main memory is divided by the storage size of write-back cache, and the regions are stored in advance. Then, a read signal from the main memory to the write-back cache is detected. It is determined whether the region corresponding to the read signal has yet to be diagnosed. If the region has yet to be diagnosed, a command to diagnose failure of the region is issued. If a write signal (write back) to a particular region is detected during the diagnosis of the particular region, the diagnosis of the particular region is stopped. Thus, the failure diagnosis of the main memory is executed in parallel with the execution of the application program.Type: GrantFiled: February 11, 2011Date of Patent: August 20, 2013Assignee: Kabushiki Kaisha ToshibaInventors: Naoya Ohnishi, Hiroshi Nakatani, Yoshito Sameda

Patent number: 8219330Abstract: A gas appliance judgment apparatus and method by which a type of gas appliance in use and the existence of a gas leak can be identified. In operation, noise is removed from measured instantaneous flow volume, whereupon the “length”, “initial flow volume” and “sequence of transited regions” of the variable portion of the flow volume and the “length”, “average value” and “gradient” of the flat portion of the flow volume are extracted. A rule having characteristics data which matches the characteristics of the variable portion and the flat portion of the flow volume is then searched, and points are added respectively for the type of gas appliance and for the existence of a gas leak. When the added points are not less than a previously established threshold value, then the type of gas appliance in use is determined, and appliance type information is output as a judgment result.Type: GrantFiled: June 2, 2011Date of Patent: July 10, 2012Assignee: Toshiba Toko Meter Systems Co., Ltd.Inventors: Yoshito Sameda, Kenji Nakano, Yukio Takanohashi, Hiroto Uyama, Masaaki Ishino

Patent number: 8131900Abstract: A memory control unit controls writing and reading of data to the slave device according to an instruction from the master device. A bus diagnosis line is directly connected from the bus signal control circuit to a bus signal receiving terminal of the slave device without passing through the address bus and the control signal line. A bus signal abnormality processing unit compares an output bus signal output from the bus signal control circuit to the address bus and the control signal line with a feedback bus signal fed back through the bus diagnosis line to determine the presence/absence of a difference. The memory control unit elongates a bus cycle period of a bus cycle of operation being executed when it is determined in the bus signal abnormality processing unit that the difference is present.Type: GrantFiled: April 30, 2009Date of Patent: March 6, 2012Assignee: Kabushiki Kaisha ToshibaInventors: Jun Takehara, Naruhiko Aramaki, Toshikazu Kawamura, Yoshito Sameda, Hiroshi Nakatani, Motohiko Okabe, Yukitaka Yoshida
