Abstract: A stator for a rotating electric machine includes a stator core and a stator coil. The stator core is formed of a band-shaped steel sheet that is helically bent and laminated. The stator core has slots each opening at an inner periphery of the stator core and spaced from one another in a circumferential direction. The stator coil is formed of electrical conductor segments that are inserted in the slots of the stator core and connected with one another. The band-shaped steel sheet has slits each of which is formed, at a position corresponding to one of the slots, to be open to the corresponding slot. Each of the electrical conductor segments is substantially U-shaped and has a pair of leg portions respectively inserted in corresponding two of the slots of the stator core; the corresponding two slots are circumferentially apart from each other by two or more slot-pitches.

Abstract: A method of visually representing output data on a screen by deflecting a laser beam in both horizontal and vertical directions for scanning, and an indicating device for performing the above method. The laser beam is first divided into two polarized waves which are, after being modulated in accordance with the output data, combined into a first synthesized laser beam. The two polarized waves are alternately extinguished synchronously with a predetermined simple harmonic oscillation. The synthesized laser beam is then horizontally deflected by means of a sinusoidally oscillating mirror so that the angular displacement of the deflection oscillates in synchronism with the predetermined simple harmonic oscillation. The resultant deflected beam is again divided into two polarized waves, one of which is then inverted. The resulting two polarized waves are combined to obtain a second synthesized laser beam whose angular displacement in deflection is unidirectional at any phase.
