Abstract: CT images near the pelvis are obtained before surgery, and a three-dimensional model of a pelvis part is created on a computer. The virtual three-dimensional bone model is used to plan an installation position of a guide instrument etc., and a virtual three-dimensional surgical site model including the guide instrument is constructed. Subsequently, during surgery, the guide instrument is installed, and three-dimensional images of a surgical site are obtained, and a measured three-dimensional surgical site model including the guide instrument is obtained. The virtual three-dimensional surgical site model and the measured three-dimensional surgical site model are compared, and an error between an ideal installation position of the guide instrument and an actual installation position of the guide instrument is detected to guide the operator to reduce the error.

Abstract: Common mode choke coil device includes four coils wound on a core in a same direction. Hot-side outputs of first and second class-D amplifiers are connected to respective ones of first ends of two of the four coils, and first and second hot-side output terminals are connected to respective ones of second ends of the two coils. Ground-side outputs of the first and second class-D amplifiers are connected to respective ones of the first ends of remaining two of the four coils, and first and second ground-side output terminals are connected to respective ones of the second ends of the remaining two coils. Single-end connection is realized by connecting a separate load to each of the class-D amplifiers via the corresponding first (or second) hot-side and ground-side output terminals. BTL connection is realized by connecting a single load to the class-D amplifiers via the first and second hot-side output terminals.

Abstract: A head apparatus includes: a head unit where a plurality of magnetic elements, which carry out reproducing and/or recording on data tracks on a magnetic tape, are disposed at equal intervals on a first straight line; a moving mechanism that moves the head unit; and a controller that carries out tracking control to cause the moving mechanism to move the head unit and keep the magnetic elements on the data tracks. The moving mechanism can rotate the head unit so as to increase or decrease an angle between a second straight line along a width of the magnetic tape and the first straight line. During tracking control, the controller causes the moving mechanism to rotate the head unit so as to increase or decrease the angle in accordance with changes in an interval between the data tracks and keep the respective magnetic elements on the respective data tracks.

Abstract: A burst interval measuring apparatus includes: a detector that outputs detection signals that can to measure a burst interval of servo patterns for a tracking servo; and a measuring unit that measures the burst interval based on the detection signals. The detector is constructed so as to be capable of outputting the detection signals that can measure the burst interval at plural positions that are separated in a width direction of the magnetic tape inside one of the servo patterns. The measuring unit uses measurement values for the burst interval at at least two positions out of the plural positions that have been measured based on the detection signals to specify velocity fluctuations in a movement velocity of the magnetic tape in the length direction and corrects the measurement values based on the velocity fluctuations.
