Patent CA-2142941-A1 (CA)
Inventor: ANICHINI LUCIANO
IPC: H02K15/09
Filed: 1995-02-20
Abstract: Dynamo-electric machine armatures which have commutators and cores that are axially close to one another are wound with the aid of wire guiding hooking plates that are inclined to reach into the portion of the commutator that is axially adjacent to the core where the coil leads must be attached to the commutator. The hooking plate may also perform an additional extension motion in order to press the coil leads out of the way of a subsequent fusing operation.    This function may alternatively be performed by a separate pusher member which is either associated with the hooking plate or independent of the hooking plate.      The fusing electrode may be specially shaped to facilitate performing fusing operations axially close to the armature core.

Patent CA-2155310-A1 (CA)
Inventor: GIBEAU FRANK C
IPC: G03B21/00
Filed: 1994-02-01
Abstract: Method and apparatus (10) for a multi-application, laser-array-based image system are disclosed. The preferred embodiment of the invention utilizes three linear laser arrays (104, 106, 108). Each linear array generates multiple (N>1) parallel output beamlets at one of the three primary colors (red, green, blue) (110, 112, 114). The corresponding 1 to N output beamlets of the three linear arrays, each individually modulated in luminance according to a specific encoding scheme representing the video image to be produced on the viewing screen (400), are combined spatially to form a single white light linear array source (100). Through a projection/scanner optical system, the N output beamlets of the white light source are simultaneously directed to, and swept horizontally across a distant viewing screen (400), resulting in a swath of N lines of a graphic video image. By producing M contiguous swaths vertically down the viewing screen, a full image of MxN lines is produced. The red, green, and blue linear laser arrays may consist of arrays of semiconductor laser diodes made of suitable semiconductor materials so as to directly emit radiation at wavelengths corresponding to red, green, and blue colors, respectively. Alternatively, the red, green and blue color arrays may be formed by arrays of semiconductor laser diodes emitting radiation at twice the desired red, green and blue wavelengths, whose radiation is coupled to arrays of second harmonic generation crystal elements. In the present invention, the simultaneous writing of N>1 lines of graphic video information (instead of N = 1 as in conventional laser projection systems) enables significant performance improvements in the optical projection/image-forming subsystems, the video luminance and chrominance encoding schemes, and the video information processing electronics.

Abstract: This invention relates to a diode pumped slab laser in the form of a slab (1) where two opposite faces (2, 3) are adapted to receive pumping radiation with the faces being cut at the Brewsters angle at one sad (6, 7) to provide entrance/exit faces for the lasing radiation. The laser radiation beam follows a zig-zag path in the slab (1) and is contained within the slab by total internal resection. The laser slab (1) is contained within an optical cavity which results in the laser beam completing a double zig-zag beam path. The design results in good pump/mode matching, mitigates thermally induced birefringence problems, overcomes amplified spontaneous emission problems, requires no coatings or curved surfaces, and is easy and relatively inexpensive to make. The slab (1) can be used within both Quasi-CW and CW modes.
