20100085060 | ELECTRIC POWER SOURCE CIRCUIT AND ABNORMALITY DIAGNOSIS SYSTEM - In a power source circuit for supplying electric power of a battery, a capacitor is charged by the battery when an ignition switch and a power supply relay are closed. The power supply relay is opened after the ignition switch is closed. The charge voltage of the capacitor falls, if the power supply relay has no fixed-closure abnormality. The charge voltage of the capacitor does not fall, if the power supply relay has the fixed-closure abnormality. A microcomputer diagnoses the power supply relay with respect to its fixed-closure abnormality based on the charge voltage of the capacitor when the ignition switch and the power supply relay are operated to open. | 04-08-2010 |
20130119782 | ELECTRIC POWER SOURCE CIRCUIT AND ABNORMALITY DIAGNOSIS SYSTEM - A control unit for a rotary electric machine includes a first current command module, a second current command module, a change module, and a return module. The first module performs a first current command on a maximum efficiency characteristic line on a d-q plane thereby to drive the machine at a maximum efficiency. The second module performs a second current command on a switching line set at a retard angle side relative to the maximum efficiency characteristic line. The change module changes a control mode from a rectangular wave voltage phase control mode to an overmodulation current control mode when an operation point of the machine reaches the switching line. The return module returns the current command from the second command to the first command after performance of the second command for a predetermined period. | 05-16-2013 |

20110112395 | MEASUREMENT DEVICE AND MEASUREMENT METHOD - A measurement device and measurement method make it possible to eliminate the load generated by stopping on a measurement subject that is moved among multiple magnetic field generating devices. The measurement device includes a first external magnetic field generating device that generates a magnetic field of a set size, a second external magnetic field generating device that generates a magnetic field of a size that differs from that of the magnetic field of the first external magnetic field generating device, a rotating table that causes the subject of measurement to pass in sequence through the magnetic fields of the first and second external magnetic field generating devices by causing the subject of measurement to move rotationally, and an OMRI measurement processing part and MRI measurement processing part that measures images such as functional images or structural images of the subject of measurement while it is being moved rotationally by the rotating table. | 05-12-2011 |
20120068705 | MEASUREMENT DEVICE AND MEASUREMENT METHOD - A measuring instrument and a measurement method which measures, using magnetic resonance, images such as a functional image, a morphologic image of an object to be measured eliminate the influences of the moving speed of the object to be measured during moving, thereby obtaining a precise measured image. The instrument comprises: the first and second external magnetic field generation devices which generate magnetic fields for exciting the magnetic resonance of a mouse (M) as a living body to be measured; a turntable which rotates and moves the mouse (M) as an object to be measured, thereby moving the mouse (M) in the magnetic fields of the first and second external magnetic field generation devices; an OMRI measurement processing unit and an MRI measurement processing unit which obtain measured image signals within the mouse (M) by phase encoding while applying a gradient magnetic field in the moving direction (y) of the mouse (M) without stopping during the movement by the turntable; and a measured signal correction unit which corrects the measured image signal (S (k., ky)), thereby obtaining a corrected image signal (S′ (k., ky)) wherein influence of movement in y-direction is corrected. | 03-22-2012 |

20150227419 | ERROR CORRECTION DECODER BASED ON LOG-LIKELIHOOD RATIO DATA - According to one embodiment, an error correction decoder includes a selecting section, calculating section, check section, and updating section. The selecting section selects data used for matrix processing applied to a process target row from LLR data stored in the first memory section based on a check matrix, and stores the data in a second memory section. The calculating section executes the matrix processing based on the data stored in the second memory section, and writes updated data back to the second memory section. The check section checks a parity based on a calculating result of the calculating section. The updating section updates the LLR data of the first memory section based on the updated data of the second memory section. | 08-13-2015 |
