Patent number: 7847574Abstract: When a stop condition is satisfied, a stop condition determination circuit (10) issues a stop instruction to an operation stop control circuit (11) to stop the operation of a functional circuit (14). A storage device (12) stores therein determination results made by the stop condition determination circuit (10) and operation conditions in the functional circuit (14). An external conveying means (13) conveys the determination results made by the stop condition determination circuit (10) to outside the semiconductor device. If these determination results are used by a peripheral device external to the semiconductor device, it is possible to prevent failures in the peripheral device and malfunctions in the system caused by faults in the semiconductor device.Type: GrantFiled: July 17, 2007Date of Patent: December 7, 2010Assignee: Panasonic CorporationInventors: Hisao Kamiya, Kazuhiro Yoshida, Takashi Ohtori

Publication number: 20090195285Abstract: A semiconductor integrated circuit is provided with one or more flip-flop circuits (10a and 10b) and a control signal generating section (20). The control signal generating section (20) outputs a control signal to control ON/OFF of the flip-flop circuits (10a and 10b). Each of the flip-flop circuits (10a and 10b) operates by receiving the clock signal and the control signal output from the control signal generating section (20).Type: ApplicationFiled: December 14, 2006Publication date: August 6, 2009Applicant: PANASONIC CORPORATIONInventors: Hisao Kamiya, Motohiro Ohki

Publication number: 20040244888Abstract: To provide a titanium alloy which is a high-strength low-alloy with a 750 MPa or more in terms of tensile strength. A production method is capable of producing the titanium alloy by using a low-priced, low-grade sponge titanium as a raw material. This high-strength low-alloy titanium alloy has an alloy composition containing O of from 0.2 to 0.8%, C of from 0.01 to 0.15%, N of from 0.01 to 0.07%, Fe of from 0.3 to 1.0% and the balance being substantially Ti. At the time of production, a low-grade sponge Ti containing N of 0.01% or more and Fe of 0.2% or more is used in at least a portion of raw materials to allow it to be a source of the aforementioned Ni and Fe components.Type: ApplicationFiled: March 9, 2004Publication date: December 9, 2004Inventors: Hiroyuki Horimura, Kosuke Doi, Akihiro Suzuki, Hisao Kamiya
