20110158375 | FUEL ASSEMBLY - A fuel assembly has a regular dodecagon fuel rod arrangement with a single fuel rod provided to each apex of a regular dodecagon having lines of length A. Assuming a direction within a horizontal plane is transverse, and a direction perpendicular to the transverse direction is longitudinal, regular dodecagon fuel rod arrangements are arranged in regular intervals in the transverse direction and the longitudinal direction. In the transverse direction, two adjacent regular dodecagon fuel rod arrangements are arranged having opposing two sides of the regular dodecagons parallel to each other with the distance of mA, wherein m is a nonnegative integer, apart from each other. With respect to the longitudinal direction, two adjacent regular dodecagon fuel rod arrangements are arranged so that the opposing two sides of the regular dodecagons are parallel to each other with the distance of nA, wherein n is a nonnegative integer, apart from each other. | 06-30-2011 |

20120031202 | TORQUE SENSOR - An excitation AC signal biased by a predetermined DC voltage is applied to a coil to allow a DC voltage component in a coil output signal to contain failure information about disconnection, partial disconnection, or the like of the coil. The DC voltage component contained in the coil output signal is detected, and the detected DC voltage is provided as an offset voltage for a failure diagnosis. Further, to check a peak level of the excitation AC voltage, a DC voltage corresponding to the peak level may be contained in the offset voltage. A differential amplifier circuit for obtaining a difference between a coil detection output AC voltage component and a reference AC voltage component outputs an obtained differential signal offset by the offset voltage. Accordingly, the differential signal containing the offset voltage as the failure information is transmitted to a circuit for torque measurement as a torque detection signal via a single output line. The circuit for torque measurement provides the torque detection data based on the transmitted differential signal and at the same time extracts the offset voltage to use it for the failure diagnosis. | 02-09-2012 |

20140239861 | Inverter Apparatus - An objective of the present invention is to improve current detection accuracy and to reduce noise of carrier frequency. A motor apparatus and a motor drive apparatus calculate motor currents Iu, Iv, and Iw using a DC bus current detected value Idc of an inverter and control a magnitude and a phase of an applied voltage of a motor to drive the motor. A carrier adjuster decreases a carrier frequency Fc of the inverter if a motor output is relatively larger and that increases the carrier frequency Fc of the inverter if the motor output is relatively smaller. A pulse shift adjuster shifts an interphase waveform of a PWM pulse according to the carrier frequency Fc. | 08-28-2014 |

20140347075 | POSITION DETECTION DEVICE - A detection coil is incorporated in a self-oscillation circuit. The oscillation frequency of the self-oscillation circuit, which comprises the coil and a capacitor, is set to a high frequency band (e.g., around 1 MHz or higher). A target section whose relative position to the coil section varies in response to displacement of a detection object, and includes a magnetism-responsive member constructed to cause inductance of the coil to vary with the relative position. A rectifier circuit extracts an amplitude level of an oscillation output signal of the self-oscillation circuit and outputs the extracted level as detected position data. For example, a plurality of self-oscillation circuits are provided. Alternatively, a single self-oscillation circuit forms a plurality of series circuits by, for each coil pair, connecting in series the two coils of the coil pair, and includes the result of connecting the series circuits in parallel as an inductor element for self-oscillation. | 11-27-2014 |

20150130444 | POSITION DETECTION DEVICE - In a position detection device of a type that omits a secondary coil, various inconveniences arising from the use of a voltage-dividing resistance (fixed resistor) are eliminated. At least two pairs of coils are provided. A magnetism-responsive member are placed so as to effect relative displacement in relation to the coils, the relative position of the member in relation to the coils varies with a position of a detection object, and impedance of each coil is varied with the relative position. The impedance changes of two coils constituting each one of coil pairs present characteristics of mutually opposite phase characteristics. For each coil pair, the two coils constituting the pair are connected in series with each other, and from a connection point thereof, a voltage-divided output voltage according to the impedance of the two coils is taken out as a detection output signal for the pair. | 05-14-2015 |
