Abstract: Stator coils each consist of a plurality of rectangular conductor coil pieces, the adjacent connection ends of which are connected to each other on the outer diameter side of a stator. The coil pieces each have: a folded portion folded in a rotation axis direction on the inner diameter side of the stator; inner diameter-side open leg portions opened from both sides of the folded portion toward the circumferential directions of the rotation axis; linear portions each bent from each of the inner diameter-side open leg portions and disposed so as to pass through the stator from the inner diameter side to the outer diameter side; and an outer diameter-side open leg portions opened from the linear portions toward the circumferential directions of the rotation axis and extending to the connection ends. The inner diameter-side open leg portions extending to the folded portion have a correction portion for correcting the position of the rectangular conductor and are formed so as to align the connection end extending to the correction portion with the connection end of the adjacent coil piece.

Abstract: It is an object of the present invention to improve visibility for observation with naked eyes or for camera shooting without spoiling the appearance during marking inside a transparent medium using a laser. By irradiating an inside of a transparent medium with a laser, the present invention forms a micro-denatured region in each of a first layer and a second layer inside the medium. The micro-denatured regions in the respective layers are arranged out of alignment with each other on a two-dimensional plane (refer to FIG. 1).

Abstract: It is made possible to amplify signal light of an optical fiber sensor and to perform measurement in a long distance. At least one of a plurality of core wires in a multicore optical fiber is used as a signal-light propagating core wire 133 and the other is used as a reference-light propagating core wire 134. Also, homodyne detection of signal light and reference light reflected by an FBG sensor unit 132 arranged in each measurement point is performed. Thus, signal light is amplified. In order to make a difference between optical path lengths of the signal light and the reference light equal to or smaller than a coherence length, an optical path-length adjustment unit including a piezoelectric element or the like is arranged in an optical path of the reference light.

Abstract: In recording technologies for batch formation of a plurality of recording bits in a recording medium by forming a plurality of optical spots using an ultrashort pulse laser and a spatial optical modulator, the batch recordable bit number has an upper limit, resulting in restricted recording speed. The intensity of the optical spot is corrected to increase the batch recordable bit number for increasing the recording speed.
