摘要： A signal processing circuit of an external device includes a CPU and a memory which are not shown. A program for estimating at least one of the position and orientation of a capsule endoscope on the basis of strength signals received through respective antennas is installed in the signal processing circuit. A single-core coil to generate a magnetic field is arranged in the capsule endoscope. The generated magnetic field is detected by a plurality of coils arranged outside a body, whereby a distance that the capsule endoscope has traveled can be obtained with accuracy. This arrangement controls image-capture timing to reliably capture images necessary for a diagnosis and prevent unnecessary image capture.

摘要： A shield member (90) is arranged on the rotor end face (18a) of an electric rotating machine (10). As the rotational velocity of a rotor (18) increases, the shield member (90) moves outward in the radial direction of a rotating shaft (12) to cover a part of the opening (86) of a slot (82). The shield member (90) controls inflow of lubricant from a portion in the axial-direction of the rotating shaft (12) on the outside of the rotor end face (18a) to the slot (82). Rotational resistance of the rotor (18) caused by stirring of lubricant can be reduced during high velocity rotation of the rotor (18).
