摘要:
A rotor of a synchronous motor, according to the present invention, includes a plurality of permanent magnets 12 radially arranged around a rotating shaft 10, and a plurality of laminated core members 14 arranged around the rotating shaft 10 and holding each permanent magnet 12 therebetween so as to constitute magnetic poles. Each permanent magnet 12 extends, as a continuum, along the substantially axial entire length of the laminated core members 14. Each laminated core member 14 is separated into two parts by a circular-plate member 24 disposed at generally center position of the laminated construction. The circular-plate member 24 is provided with a shaft hole 26 at the center thereof, into which the rotating shaft 10 is fitted, and a plurality of magnet-fastening holes 28 around the shaft hole 26. The magnet-fastening holes 28 have peripheral edges 32 with substantially the same profile as a cross-section of the permanent magnets 12, and are formed at the positions substantially corresponding to the positions of the permanent magnets 12. Therefore, each permanent magnet 12 is fastened at a predetermined position in a radial direction by the magnet-fastening hole 28 of the circular-plate member 24, against an external force acting radially outwardly such as centrifugal force.

The present invention provides a rotor for a synchronous rotary machine, having a rotor core (23) provided in its outer circumference with recesses (26), and permanent magnets (25) each fitted radially in each recess (26) so that its lower surface (25b) will be seated on the bottom surface of the recess (26). Each permanent magnet (25) and each recess (26) are formed so that gaps are formed between the inclined side surfaces (27a, 27b) of the permanent magnet (25) and the corresponding inclined side surfaces (26b, 26c) of the recess (26), and an adhesive filling up the gaps is hardened to form wedging layers (30) capable of restraining the permanent magnet (25) from being separated from the surface of the rotor core (23) by forces acting on the permanent magnet (25) to separate the permanent magnet (25) from the surface of the rotor core (23).

A nonlinear diode having a first electrode, a second electrode, and a nonlinear resistance film of hydrogenated amorphous silicon nitride formed between the first and second electrodes and having an optical bandgap ranging between 2.0 and 2.2 eV. The nonlinear diode further comprises an additional hydrogenated amorphous silicon nitride film between the nonlinear resistance film and the second electrode. The additional hydrogenated amorphous silicon nitride film has an optical bandgap greater than that of the hydrogenated amorphous silicon nitride in said nonlinear film. A nonlinear diode according to the present invention may also comprise first and second electrodes and an amorphous film formed between the first and second electrodes. The amorphous film includes a first hydrogenated amorphous silicon nitride film and a second hydrogenated amorphous silicon nitride film. The first hydrogenated amorphous silicon nitride film has an optical bandgap ranging from 2.0 to 2.2 eV and the second hydrogenated amorphous silicon nitride film has an optical bandgap greater than that of the first hydrogenated amorphous silicon nitride film.

An inorganic ion exchanger prepared by kneading a blend of anatase type titanic acid or amorphous titanic acid with sulfuric acid, hydrochloric acid or phosphoric acid and water, extrusion molding the blend, and thereafter, heat treating the extruded product at an elevated temperature. The inorganic ion exchanger has high strength in water and is suitable for use in the removal or the concentration and recovery of injurious or beneficial materials contained in water.
摘要:
A mode changing apparatus for a tape recorder to initiate a change in mode including a loading gear having at least a portion magnetized in N and S poles and an electromagnet adjacent to the magnetized portion of the loading gear. When a trigger signal is applied to the electromagnet responsive to the selection of a mode of operation for the tape recorder, the loading gear is brought into meshing engagement with a drive gear. The drive gear is driven and disposed so it does not mesh with the loading gear until the electromagnet is energized. Once the electromagnet is energized to engage the drive gear and loading gear the rotation of the loading gear effects the mode change of the tape recorder.
