Publication number: 20110015916Abstract: A simulation system having multiple peripherals that communicate with each other. The system includes a weighted graph with weights set as communication times. The peripherals are represented as nodes and connection paths are represented as edges. Among the communication times in the loop, the minimum time is set as first synchronization timing. Timing with an acceptable delay added is set as second synchronization timing. Timing set by a user to be longer than the first and second timings is set as third synchronization timing. The third synchronization timing is used in a portion where the timing is usable, thus synchronizing the peripherals at the longest possible synchronization timing.Type: ApplicationFiled: July 12, 2010Publication date: January 20, 2011Applicant: International Business Machines CorporationInventors: Masaki Kataoka, Hideaki Komatsu, Goh Kondoh, Fumitomo Ohsawa

Publication number: 20100293314Abstract: CPU architecture is modified so that content of the interrupt mask register can be changed directly based on a decoding result of an instruction decoder of a CPU. Such modification does not require a great deal of labor in changing a CPU design. In addition, an extended CALL instruction and an extended software interrupt instruction are added to the CPU, and each of the extended CALL instruction and the extended software interrupt instruction additionally has a function of changing the value of the interrupt mask register. Atomicity is achieved by: allowing such a single instruction to concurrently execute a call of a process and a value change of the interrupt mask register; and disabling other interrupts during execution of the single instruction.Type: ApplicationFiled: May 13, 2010Publication date: November 18, 2010Applicant: INTERNATIONAL BUSINESS MACHINES CORPORATIONInventors: Masaki Kataoka, Hideaki Komatsu

Patent number: 7632400Abstract: A water treatment equipment has a raw water tank as a mixing section, a micronanobubble generation tank, a floatation tank, and a treated water tank. Waste water as treatment water is introduced into the raw water tank and mixed with the water containing micronanobubbles produced by the micronanobubble generation tank. Thereafter, the waste water, as treatment water, is introduced into a lower mixing section of the floatation tank from the raw tank by a raw water tank pump. Also, treatment water containing fine bubbles is introduced into the lower mixing section from a pressure tank. Therefore, the micronanobubbles is mixed with the fine bubbles in the lower mixing section of the floatation tank, thereby almost all the suspended matter in the treatment water is surfaced. Thus, the water treatment equipment enhances separatability of suspended matter.Type: GrantFiled: June 19, 2007Date of Patent: December 15, 2009Assignee: Sharp Kabushiki KaishaInventors: Kazuyuki Yamasaki, Kazuyuki Sakata, Kazumi Chuhjoh, Masaki Kataoka

Patent number: 7628912Abstract: The application device for liquid containing micro-nano bubbles generates micro-nano bubbles in a wide size distribution with use of a submerged pump-type micro-nano bubble generator and a spiral flow-type micro-nano bubble generator. A micro-nano bubble generating aid metering pump is controlled by a bubble level meter and a level controller, so that the supply amount of a micro-nano bubble generating aid is controlled in response to the level of bubbles from a fluid level. The supply amount of a micro-nano bubble generating aid is also controlled by a turbidimeter and a controller in response to the turbidity of the liquid in a micro-nano bubble generation tank, while the amount of air supplied to the submerged pump-type micro-nano bubble generator is controlled in response to the turbidity of the liquid. Therefore, the device can produce a large amount of various micro-nano bubbles in a wide size distribution more economically.Type: GrantFiled: September 4, 2007Date of Patent: December 8, 2009Assignee: Sharp Kabushiki KaishaInventors: Kazuyuki Yamasaki, Kazuyuki Sakata, Kazumi Chuhjoh, Masaki Kataoka
