Title: Semiconductor laser
Inventor: NAKATSUKA SHINICHI
IPC: H01S3/00
Filed: 1993-08-20
Abstract: PURPOSE:To obtain a beam deflection semiconductor laser so constituted that the position and direction of projection, of the laser beam can be easily varied by controlling injection current. CONSTITUTION:An independent current injection region, deviated from the axis of a waveguide (straight line position 10), is formed in the waveguide (boundary portion 11) in proximity to the end face of a semiconductor laser. A desired refractive index distribution is formed by modulating current injection to the current injection region. Thus both the position and direction of laser beam projection can be controlled by varying current injection to the end face region and thereby refracting laser light.

IPC: H04N7/081
Filed: 1992-08-04
Abstract: PURPOSE:To insert and demodulate information signals which can not be easily decoded, altered nor deleted without influencing video signals. CONSTITUTION:The difference of the information signals whose phases are opposite with each other inserted to two horizontal lines with strong line correlation in one or plural adjacent fields in the fields same or different for the video signals is found by the combination of a delay circuit 36 and a subtracter 38.

Abstract: PURPOSE:To attain erasure of a desired vertical Bloch line pair indeqendently of an information string by providing a planer magnetizing layer and injecting one Bloch point of a vertical Bloch line pair. CONSTITUTION:In applying a planer rotating field to a plane magnetizing layer 32 extended over a major loop, a stripe domain is extended and reaches the end of a minor loop 31. In taking off the planer rotating field succeedingly, the magnetization of a vertical Bloch line (VBL) in the layer 32 is inverted partially by a floating magnetic field from a stripe domain storage layer, and the Bloch point being the boundary section is injected, the direction of the magnetization of the VBL34 is inverted and becomes the same direction as the other VBL pairs remaining at the outside of the layer 32. Then, the VBL pairs in the same direction are approached and combined on the loop 31 and a pair of the VBL pair is erased. The desired VBL pair is erased by injecting one Bloch point of the VBL pair desired to be erased via the planer rotating field, independently of the information train, even if the VBL pairs are not continuous.
