Abstract: A detecting system of the position and the posture of a capsule medical device includes a main body of the capsule medical device that is inserted in a living body, a coil in a capsule that is arranged to the main body of the capsule medical device and forms a resonant circuit, a magnetic field generating device that is arranged around the living body and generates the Alternating magnetic field for generating an induced magnetic field in the coil in the capsule, and a plurality of magnetic field detecting devices that detect the strength of the induced magnetic field generated by the coil in the capsule by the magnetic field generated by the magnetic field generating device.

Abstract: In a capsule 3 as a medical apparatus inserted into a body cavity, the lengthwise direction of the capsule 3 is used as an insert axis, a manipulation/input device 8, which is magnetized in a direction orthogonal to the insert axis, is disposed at the center position of the insert axis. A magnetic field generation device 4, which is disposed outside of a body, is caused to generate a vibration magnetic field in a direction parallel with the insert axis of the capsule 3 by turning on a vibration (ON/OFF) switch 8f of a manipulation/input device 8 so that couples having lines of action, which are in parallel with the insert axis, are exerted on the capsule 3, thereby the capsule 3 executes a swiveling motion about the insert axis and smoothly travels along a cavity organ.

Abstract: A medical apparatus main body such as a capsule main body inserted in the body cavity includes a thrust generating mechanism such as a spiral projection. The medical apparatus main body further forms an information providing unit comprising at least one of a storing unit for storing a state of the thrust generating mechanism and a direction detecting unit for detecting the direction of the medical apparatus main body. An input unit instructs a thrust generating direction of the thrust generating mechanism and thus a control unit changes continuously or the like a thrust generating state of the thrust generating mechanism based on information from the information providing unit.

Abstract: The present invention provides a method of manufacturing a silicon steel sheet having grains precisely arranged in the Goss orientation, comprising the steps of preparing a steel material containing 0.01 wt % or less of C, 2.5 to 7.0 wt % of Si, 0.01 wt % or less of S, 0.01 wt % or less of Al, 0.01 wt % or less of N, subjecting the steel material to hot rolling maintained 1000.degree. C. or higher such that the temperature of the rolled material at an end of the hot rolling step falls within the range of 700.degree. to 950.degree. C., subjecting the steel material to a primary cold rolling process at a rolling reduction of 30 to 85%, annealing the steel material at a temperature of 600.degree. to 900.degree. C., subjecting the steel material to a secondary cold rolling process at a rolling reduction of 40 to 80%, annealing the steel material again at a temperature of 600.degree. to 900.degree. C.
