Patent GB-2263213-A (GB)
Title: Coded qam system
Inventor: WILLIAMS RICHARD GUY CARRINGTO
IPC: H04L27/34
Filed: 1993-02-04
Abstract: A block of output symbols is generated, using quadrature amplitude modulation, from a block of input bits. The input bits are processed, using one or more redundant codes having a Hamming distance greater than one, to produce digital words which control the in-phase components and digital words which control the quadrature components of the output symbols. A group of bits generated by a single coding step supplies bits for both types of digital word, thereby enabling that coding step to process simultaneously a larger number of bits than would be the case if separate coding were used for producing the two types of word.

Title: Optical radiation devices
Inventor: WOOD DAVID CHARLES
IPC: H04B10/112
Filed: 1993-07-28
Abstract: A device, particularly an antenna device, for emitting a beam of optical radiation to irradiate a remote target area. The device includes an optical source (10) having a limited wavelength band, and a hologram pattern (14) positioned in the path of a light beam originating from the source, the pattern being selected to produce a composite beam (20) having a predetermined shape or far field pattern conforming to the target area and/or a predetermined distribution of light intensity in the target area. Where the optical source is a point source, the hologram pattern (10) selectively retards the phase of respective components of the incident wavefront to produce a composite beam having a far field pattern that precludes focusing of the beam into a single small spot The device has particular application in a telecommunication system wherein a data signal is transmitted through free space by an optical beam, at least one characteristic of the beam being controlled by the hologram pattern in the path of the beam. <IMAGE>

Title: Bonding method for electric element
Inventor: KIMURA YUJI
IPC: H01L23/492
Filed: 1995-07-31
Abstract: A method for bonding a semiconductor device to a pedestal, which can obtain a sufficient bonding strength and stable electric contact, are disclosed. On an n-type electrode constituting an ohmic electrode for a semiconductor laser device are formed a Ni layer and a Sn-containing solder layer. Then, the solder layer is melted and bonded to a heat sink provided with Au-plating. The film thickness of the Ni layer is set to approximately 500Ñ or more. When the solder layer is melted, Ni in the Ni layer diffuses into the solder layer and Sn in the solder layer diffuses into the Ni layer. By this mutual diffusion, bonding strength and wettability between the semiconductor device and pedestal can be improved.

IPC: H04N7/18
Filed: 1997-12-05
Abstract: An image capturing device 2, 3 transmits image information to a receiving station 4 where images of a scene 26 are displayed. The devices 2,3 respond to a request for a specific image from the receiving station 4 by transmitting a specific differential image from a stored 12 set of differential images. The differential image is then merged with a reference image 8 in the device to provide a new reference image for future use in deriving new differential images. The previously held set of differential images is discarded. At the receiving station 4 the differential image is combined with the locally stored (and displayed) image to produce a new image for display and storage.
