    摘要: To provide a control circuit and control method of a step-up/step-down type DC-DC converter capable of realizing high efficiency. In a state (1), a terminal Tx of a choke coil L1 is connected to an input terminal Tin, and a terminal Ty is connected to a reference potential. In a state (2), the terminal Tx is connected to the reference potential, and the terminal Ty is connected to an output terminal Tout. In the state (3), the terminal Tx is connected to the input terminal Tin, and the terminal Ty is connected to the output terminal Tout. A first period operation TO1 is constituted by the states (1) and (2), and a second period operation TO2 is constituted by the states (1) and (3). A second period T2, in which the second period operation TO2 is performed, is a value n times as long as a first period T1, in which the first period operation TO1 is performed. In the second period operation TO2, the state (1) is switched to the state (3) so that an increasing slope of an inductor current IL is reduced.

    摘要: A processing circuit, which carries out coincidence counting, acquires calibration data so that time delays of γ-ray detection signals from radiation detectors coincide with one another. A technique for acquiring calibration data faster and easily is provided to attain high time precision and respond to multi-channeling of detectors. A signal from a test signal generator is sent to signal processing apparatuses and coincidence count events are generated as a test. The events generated are processed by a delay time control apparatus and a variable delay circuit is controlled to improve the accuracy of coincidence counting.

    摘要: A diagnostic system for an engine includes: a plurality of cylinders, in-cylinder injectors, port injectors and an electronic control unit. The electronic control unit configured to make an abnormality diagnosis of an air-fuel ratio due to the in-cylinder injectors and then to make an abnormality diagnosis of the air-fuel ratio due to the port injectors. The electronic control unit is configured to make an abnormality diagnosis of the air-fuel ratio due to the in-cylinder injectors in an operating situation in which fuel is injected from only the in-cylinder injectors, and to make an abnormality diagnosis of the air-fuel ratio due to the port injectors by increasing a ratio of an injection amount of the port injectors when the electronic control unit has diagnosed that there is an abnormality of the air-fuel ratio in an operating situation in which fuel is injected from both the in-cylinder injectors and the port injectors.
