First and second protruding portions are disposed so as to project from inner wall surfaces of portions of first and second yoke portions at root portions of first and second claw-shaped magnetic pole portions, and first and second recess portions are recessed into inner wall surfaces of portions of the first and second yoke portions that face the second and first protruding portions. In addition, a shape of a region in which the field coil is disposed is configured into a wave shape that has a cross-sectional shape in a plane that includes a central axis of the pole core that is approximately constant in a circumferential direction and that zigzags alternately in an axial direction at positions of each of the first and second claw-shaped magnetic pole portions.

Abstract: A wire rope flaw detector comprises a back yoke and excitation permanent magnets, which form a main magnetic path in a predetermined section of a wire rope in the axial direction; a magnetic path member arranged in the predetermined section to be magnetically insulated from the back yoke and the permanent magnets and making the leakage flux generated from a damaged part of wire rope detour to the outside of the wire rope; and a detection coil wound around the magnetic path member for detecting leakage flux. The amount of leakage flux can be increased by providing the magnetic path member and since the windable area of the detection coil is increased, the number of turns of detection coil can be increased.

Abstract: A dynamoelectric machine including first and second permanent magnets held by first and second magnet seats on first and second yoke portions so as to face inner circumferential surfaces of tip end portions of first and second claw-shaped magnetic pole portions. The first and second permanent magnets are magnetically oriented in a reverse direction to orientation of a magnetic field that the field coil produces. The dynamoelectric machine enables permanent magnet holding reliability to be increased, induced voltage during no-load de-energization to be suppressed, and thermal demagnetization of magnets due to high-frequency magnetic fields that are induced by stator slots to be avoided.

Abstract: Survey of fishery resources is automatically effected by providing an identification element (i.e. IC tag) to each fishing gear, locating a plurality of such fishing gears under the sea to catch fishery resources, thereafter, using a reading device (e.g. tag reader) to read all the identification elements to obtain an identification data for each of the fishing gears, while obtaining an operating position in this survey by GPS device, and then counting number of fish catches for each of the fishing gears. All the data thus obtained are processed by a computer, so that a data of fishery resources distribution under the sea can be obtained automatically, without requiring much labor and expenses in conducting the survey. A device for effecting such method is also provided.

Abstract: An image distortion correcting device with reduced cost and reduced consumption power is provided. Horizontal correction coils (L1) and (L2) are wound around partial cores (4a) and (4b). The two horizontal correction coils (L1) and (L2) are wound in such winding directions that they produce magnetic fields in opposite directions. A bobbin (5) having an insulating property covers the partial cores (4a) and (4b) and magnets (2) and (3) in the winding direction of the horizontal correction coils (L1) and (L2), and a vertical correction coil (L3) is wound on the bobbin (5) around the partial cores (4a) and (4b) along the windings of the horizontal correction coils (L1) and (L2). That is to say, the vertical correction coil (L3) is wound over the horizontal correction coils (L1) and (L2) along the periphery of their windings with the bobbin (5) interposed therebetween.

Abstract: An image distortion correction circuit is provided in which a horizontal deflection current (IH) flows through horizontal correction coils (L1, L2) and a vertical deflection current (IV) flows through either of vertical correction coils (L3, L4). The vertical correction coils (L3, L4) and the horizontal correction coils (L1, L2) are wound on the same core (4). A pair of magnets (2, 3) on opposite ends of the core (4) apply a biased magnetic field from the north pole toward the south pole. The anode of a diode (D1), the cathode of a diode (D2) and a first end of a resistor (R1) are connected to an intermediate terminal (P11) through which the vertical deflection current (IV) flows. A first end of the vertical correction coil (L3) is connected to the cathode of the diode (D1). A second end of the resistor (R1) and a terminal (P4) are connected to a second end of the vertical correction coil (L3).

Abstract: A belt-shaped member cut into a predetermined length is fed from a feeding devices to a tire forming drum and is wound on its cylindrical peripheral surface. Center portions of the opposite ends of the belt-shaped member are pushed to be joined to each other and the side portions of at least one of the opposite ends of the belt-shaped member are held by upper and lower holding pawls. Such holding pawls are swung along an arcuate path so that both side portions of the opposite ends of the belt-shaped member are drawn near each other to abut against each other. The abutting end portions are pushed toward the peripheral surface of the drum by pushing devices for joining them together.
