Patent EP-0272419-A3 (EP)
IPC: C08G63/64
Filed: 1987-11-05
Abstract: Thermoplastic copolyester-carbonate resins are 
described, having included in their polymer chains, a 
moiety of the formula:-

     The resins are useful intermediates for branched 
or cross-linked molding compositions.
Patent EP-0270045-A3 (EP)
IPC: G02B6/32
Filed: 1987-11-28
Abstract: An optic fiber connection system is provided which 
enables the forming of a lens or bead (112) at the end of an 
optic fiber (114) and the positioning of the lens for 
coupling to another optic fiber. The contact (118) has a 
front end portion formed of a dielectric. A hole 
extends along the contact axis for receiving the optic 
fiber. A cross aperture in the dielectric front end 
portion extends perpendicular to the hole. With the 
tip of the optic fiber lying in the cross aperture, 
heat is applied to the tip to form a nearly spherically 
shaped lens thereon by electric arc heating. Because 
the front end portion is formed of a dielectric, it 
does not interfere with the creation of the arc and the 
heating of the fiber. The arc (132) is formed by positioning 
the tips (120,122) of a pair of electrodes (124,126) to lie 
slightly within opposite ends of the cross-aperture, to avoid 
establishing an arc between the electrodes which passes 
around the contact instead of through the 
cross-aperture. The electrodes are spaced apart by at 
least about eight times the diameter of the optic 
fiber, to avoid deposition of vapors from the heated 
optic fiber onto the electrodes.

Title: Low cost symbol error correction coding and decoding
IPC: H03M13/13
Filed: 1990-02-16
Abstract: Byte or symbol organized linear block codes are optimized 
in terms of reducing the number of ones in their parity 
check matrices by means of symbol column transformations 
carried out by multiplication by non-singular matrices. 
Each optimized symbol column preferably, and probably 
necessarily, includes a submatrix which is the identity 
matrix which contributes to low weight check matrices and 
also to simplified decoding procedures and apparatus. 
Since circuit cost and layout area are proportional to 
the number of Exclusive-OR gates which is determined by 
the number of ones in the check matrix, it is seen that 
the reduction procedures carried out in accordance with 
the present invention solve significant problems that are 
particularly applicable in the utilization of byte 
organized semiconductor memory systems. Reduced weight 
coding systems are also generated in accordance with 
weight reducing procedures used in conjunction with 
modified Reed Solomon codes. The decoding and encoding 
methods and apparatus are extendable to the inclusion of 
any number of check symbols.
