  • Publication number: 20120152714
    Abstract: A switch includes a movable contact piece having one end as a supporting point of turn and the other end arranged with a movable contact, a turning member having the other end as a supporting point of turn, a coil spring having one end locked to one end of the turning member and the other end locked to an intermediate portion of the movable contact piece, and a push button supported and slidable in an up and down direction. The movable contact piece is inverted by pushing down the one end of the turning member with the push button so as to make the movable contact approach and separate from a fixed contact. The turning member includes a position regulating portion that is brought into contact with the coil spring and brings the movable contact into contact with the fixed contact while maintaining a contact state with the coil spring.

  • Publication number: 20120141007
    Abstract: 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.
