摘要:
In multi-echo multi-contrast imaging, the image quality is improved by suppressing an increase in imaging time. In order to do so, the arrangement order of echo signals that form an echo train and k space filled with each echo signal are determined such that the continuity of the echo arrangement is maintained while sharing an echo signal between contrasts in multi-echo multi-contrast imaging. Echo trains that perform echo sharing are arranged in non-oscillatory centric view ordering (NOCO). In addition, the starting point of echo sharing of one echo train is connected to the same position of another echo train. When some discontinuous regions are present, the discontinuous regions may be corrected using continuous data of regions symmetrical thereto on the k space.

The threshold voltage is shifted in a negative or positive direction in some cases by an unspecified factor in a manufacturing process of the thin film transistor. If the amount of shift from 0 V is large, driving voltage is increased, which results in an increase in power consumption of a semiconductor device. Thus, a resin layer having good flatness is formed as a first protective insulating film covering the oxide semiconductor layer, and then a second protective insulating film is formed by a sputtering method or a plasma CVD method under a low power condition over the resin layer. Further, in order to adjust the threshold voltage to a desired value, gate electrodes are provided over and below an oxide semiconductor layer.

In an information processing apparatus, a first processor executes firmware and data processing instructions, a second processor conducts management of firmware updating and system settings, first and second memories store current and updated firmware, a third memory stores system settings information, and a switch changes connections of the first and second memories under control of the second processor, to connect one of the first and second memories to a bus connected to the first processor and to connect the other to the second processor. During firmware execution by the first processor, the second processor reads the system settings information from the third memory and provides it to the first processor. The first processor reflects firmware data from updated firmware in the second memory in the system settings information and the second processor stores the system settings information in which updated firmware data is reflected into the third memory.

An image with a desired contrast is obtained while suppressing body motion artifacts caused by both random motion and periodic motion of an object. In order to do so, an imaging sequence using a non-Cartesian sampling method is executed so as to synchronize with a biological signal only at the start time and a repetition time (TR), which is an execution interval between shots within the imaging sequence, is maintained. In addition, a time difference between a delay time and a start time of each shot is calculated, and a shot with a predetermined time difference or more is executed again after the TR time.

A flexible coupling includes: spool members disposed equidistantly on a circumference; torque transmission lines disposed around adjacent pairs of the spool members; and an annular elastic body in which the spool members and the torque transmission lines are embedded. The torque transmission lines consist of first torque transmission lines, and second torque transmission lines whose total sum of cross-sectional area is a half of that of the first torque transmission lines. The flexible coupling is constructed so that the first torque transmission lines transmit positive torque and the second torque transmission lines transmit negative torque, and is incorporated into a vehicle motive power transmission apparatus that has a hypoid gear whose mesh transmission error is greater during transmission of negative torque than during transmission of positive torque.
