Patent EP-0296720-A2 (EP)
Inventor: CHIU KIN-CHUNG RAY
IPC: B01D53/64
Filed: 1988-05-27
Abstract: Vapor phase waste species are removed from effluent gas streams using a plasma extraction reactor (10) comprising a pair of parallel, spaced-apart electrodes (20,22). The electrodes are driven under conditions, usually at radio frequency, to induce a glow discharge in the waste species, and the excited species are deposited directly on the electrode surface. By providing a very high ratio of electrode area to reactor volume and waste gas volumetric flow rate, substantially complete removal of the waste species can be effected. The system is particularly useful in removing contaminant species discharged from semiconductor processing operations, such as chemical vapor deposition and plasma etching. The method and system are particularly advantageous in that the vapor phase waste products are converted to a solid phase deposited directly on the electrodes which may then be disposed.

Abstract: A composition and process of use for a bath comprising a sulfonic acid as a cleaning or microetch solution in one of the preparation steps for preparing printed circuit boards for acid copper electroplating thereon. The metal surfaces of the copper laminate glass epoxy sheets which have been previously imaged with a photoimageable dry film resist must be cleaned to remove any organic residues of the resist which remain to avoid causing defects in the electroplated copper. The sulfonic acid solution may also contain surface active agents, complexing agents, chelating agents, or other salts such as phosphates, polyphosphates, sulfates, sulfonates or chlorides. The additives are soluble, free-rinsing, and stable in the acid solution and exhibit the required cleaning action on the surface of the copper.

Abstract: In order to produce relatively large quantities of recombinant polypeptides having good ovine growth hormone activity which can be used  in vivo  as effective substitutes for the natural hormone, a complementary DNA (cDNA) sequence coding for a recombinant polypeptide having ovine growth hormone activity is provided together with a suitable cloning vector, so that the DNA sequence and cloning vector are ligated to deploy the DNA sequence into the cloning vector to form a molecular clone. The vector so formed may include a complete or partial copy of the ovine growth hormone polypeptide coding region, encompassing the mature hormone, extending past the 3′ termination codon. The DNA sequence coding may be derived from polyadenylated messenger RNA (mRNA) isolated from ovine pituitary glands by treating the mRNA with reverse transcriptase in the presence of oligodT primer to synthesize first strand complementary DNA (cDNA), enzymatically removing the mRNA with RNase H, and subsequently synthesising the second cDNA strand with DNA polymerase I, and treating the double stranded complementary DNA (cDNA) so formed with T4 DNA polymerase to create flush (blunt) ended molecules.

Abstract: A toner mass developed control system for use with electronic printers or copiers provides for the measurement of toned photoconductor reflectivity and bare photoconductor reflectivity. The standard control ratio is modified by characterizing the particular sensor unit in use and by taking into account the reflectance from both photoconductor and toner in the toned patch reflectivity measurement. These factors together with a modification for photoconductor reflectance degradation enable accurate control in high optical density development and with highly reflective color toners by altering the control ratio in accordance with these factors.
