摘要:
A rotating electrical machine includes a rotor, in which a plurality of magnetic poles are provided in circumferential direction, and a stator, within which the rotor is disposed. In the stator, two stator magnetic poles are formed by winding coils of one phase and by a stator core of the stator within 360° of electrical angle defined by the magnetic poles of the rotor. The coils that form respective stator magnetic poles have angular widths in circumferential direction of less than 180° of electrical angle, the coils that form the respective two stator magnetic poles are provided so as not to mutually overlap and are wound so that adjacent ones of the stator magnetic poles have mutually opposite polarities, and, in the stator, each winding of each coil consists of an external bridge wire, a turn portion, an internal bridge wire, and a turn portion, in that order.

According to the present invention, a capsular endoscope having at least an image pickup optical system, an illumination unit, an image pickup portion, and a circuit board comprises a marker shooting unit that indwells a marker member in a body cavity. Consequently, a predetermined marker is indwelled in a desired region such as a lesion discovered using the capsular endoscope so that the region can be readily rediscovered during reexamination.

To obtain a paste for electron sources which can enhance heat resistance of carbon nanotubes, which can suppress burn-out of the carbon nanotubes even during heating at a high temperature, and can exhibit a high electron emission performance, boron (B) is added to the paste formed of the carbon nanotubes and metal. Due to the addition of boron, the oxidation of the carbon nanotubes can be suppressed, and the degradation of the electron emission characteristics and the degradation of the uniformity of the emission of electrons during the heating process such as baking can be prevented.

A wire-stranded hollow coil body (1) has a multitude of coil line elements (2) stranded along a predetermined circular line to form a flexible wire tube having a central axial hollow portion (3), the flexible wire tube is stranded under a strand-turn resistant load and heat treated to remove a residual stress upon formation so as to provide a high rotation-following capability and a high straightness. Further, a method provides a way to strand the coil line elements (2) under a strand-turn resistant load while heat treating the coil line elements (2).

An information preparation device, such as a personal computer, detects non-consecutive position information, such as times and dates, based on parameters (S11), such as preinputted non-consecutive point detection margins, and prepares (S12) an information table with image information for each non-consecutive position. Based on editing parameters, the device synthesizes and edits (S13) the information in the information table by date and the like. Then the device divides the information into objects, which is a data format, by data The device retrieves contents information and the like that corresponds to the divided information, and generates (S14) and outputs (S15) scenario information. The date and the like indicated by the divided regions serve as an index on buttons of menus that the user operates to easily select and display a desired images.

A gap defined between cathode wires 2 having electron emitting sources 2a and control electrodes 4 is made uniform and a thickness of an insulation layer 3 interposed between both of them is made thin or the insulation layer 3 is eliminated whereby the electron emission characteristics and the high-frequency driving of high performance can be realized. The control electrodes 4 which have recessed portions 4c in plate-like members and have holes 4a for allowing electrons to pass therethrough in bottom portions thereof restrict the gap defined between the cathode wires 2 and the control electrodes 4 by adjusting a plate-thickness direction size of the holes 4a formed in the control electrodes 4.

A method of analyzing electromagnetic fields created in a rotary machine and an analyzer. The method and analyzer provide for an electromagnetic field in a total analysis space of a rotary machine including a stator space containing a stator and a rotor space containing a rotor to be analyzed to determined a boundary field between the stator space and the rotor space. The boundary field in a direction of rotation in modes is expanded and the modes obtained by expansion are converted into rotating magnetic field components. using the rotating magnetic field components as boundary conditions for a boundary between the stator space and the rotor space, an electromagnetic field in the stator space is analyzed and an electromagnetic field in the rotor space is analyzed.
